FedRAMP-compatible trust centers: the complete guide to requirements, architecture, and how SecureSlate meets them

Picture an agency Information System Security Officer on a Tuesday afternoon. Their program office wants to adopt your cloud service. Before anyone signs, they need your current security package, last month's vulnerability scan summary, and your open plan of action items. Under the old model, that meant finding the right portal, filing an access request, waiting for a package administrator, and then reading a PDF that may already be weeks out of date.

FedRAMP is replacing that experience. Under FedRAMP 20x and the Consolidated Rules for 2026, cloud service providers are expected to store and share their certification data through a FedRAMP-compatible trust center: a provider-owned system that keeps security information current, gives agencies self-service access, logs who saw what, and exposes the same data to machines through a documented API.

That is a bigger shift than it sounds. A trust center stops being a sales asset and becomes part of your FedRAMP obligations. FedRAMP can ask for its access inventory. Agencies can point their GRC tools at its API. And a stale or unreachable trust center becomes a compliance problem, not just an awkward sales moment.

This guide is written for security, compliance, and engineering leaders at cloud providers who sell, or plan to sell, to the federal government. It covers:

• What a FedRAMP-compatible trust center is, and how it differs from the model it replaces
• Every requirement, with what good looks like, common pitfalls, and the evidence FedRAMP may ask for
• A reference architecture and examples of machine-readable data and access logs
• An operating model, the mistakes that trip teams up, and a 90-day rollout plan
• How SecureSlate's Trust Center supports each requirement, and what to confirm for your offering

Key takeaways

• FedRAMP now expects providers to store and share certification data (called authorization data in earlier documents) through a FedRAMP-compatible trust center that the provider owns and operates.
• The rules come from FedRAMP's Authorization Data Sharing standard for 20x and continue in the Certification Data Sharing rules within the Consolidated Rules for 2026.
• The MUST requirements: a visible, clearly labeled trust center; public offering information kept consistent across human and machine-readable formats; responsible sharing; documented programmatic access to all certification data; an inventory and history of agency users and systems; access logs with summaries kept for at least six months; and reporting denied agency requests to FedRAMP within five business days.
• The SHOULD requirements: view and download in both human and machine-readable formats, and self-service access management for agencies.
• The Consolidated Rules for 2026 took effect on July 4, 2026, with enforcement beginning after January 1, 2027. FedRAMP has described a transition for Rev5 providers to trust centers extending into 2027.
• A FedRAMP-compatible trust center is an operational system, not a web page. It needs owners, response targets for access requests, an update cadence tied to continuous monitoring, and monitoring of its own.
• SecureSlate's Trust Center provides gated sharing with approval workflows, recorded access decisions, NDA and MSA acceptance, live framework status, controls, subprocessors, and update notifications, fed by continuous monitoring mapped to FedRAMP 20x Key Security Indicators.

What is a FedRAMP-compatible trust center?

Three terms do most of the work in FedRAMP's rules. It helps to pin them down before getting into requirements.

Term	Plain-language meaning
Trust center	The system a cloud service provider uses to store and share FedRAMP certification data with FedRAMP, agencies, and other necessary parties
Certification data	The information that supports a FedRAMP decision and ongoing reuse: package or 20x materials, Key Security Indicator results, continuous monitoring reports, plans of action, incident and significant change communications
FedRAMP-compatible	A trust center that meets FedRAMP's rules for publishing, protecting, providing programmatic access to, and logging access to certification data
Necessary parties	Everyone with a legitimate need for the data: FedRAMP, agencies evaluating or using the service, and others such as assessors acting on their behalf
Key Security Indicators (KSIs)	The measurable security outcomes FedRAMP 20x uses to assess a cloud service, in place of relying mainly on documented narratives

Under the 20x Authorization Data Sharing standard, providers of 20x offerings are required to use a FedRAMP-compatible trust center. Rev5 providers have historically shared through the USDA Connect Community Portal, and FedRAMP has signaled that Rev5 providers are expected to move to FedRAMP-compatible trust centers as well.

The core idea: the provider owns the data and keeps it current, and agencies get direct, logged, self-service access to it. FedRAMP shifts from being the place data lives to being the party that sets the rules and checks they are followed.

---

The old model vs. the trust center model

The easiest way to understand what FedRAMP is asking for is to compare it with how package sharing has traditionally worked.

Dimension	Traditional package sharing	FedRAMP-compatible trust center
Where data lives	Central repository or portal	Provider-operated trust center
Freshness	Point-in-time uploads	Kept current by the provider, ideally automated
Format	Mostly documents and spreadsheets	Human-readable and machine-readable, with API access
Access path	Request through a central gatekeeper	Self-service for agencies, with provider approval where needed
Who logs access	The central repository	The provider, with an inventory FedRAMP can review
Agency tooling	Manual download and review	Agency GRC tools can pull data programmatically
Accountability for availability	The central repository	The provider

Two consequences follow. First, availability of your trust center is now your problem. If it is down when an agency needs it, that reflects on your offering. Second, the trust center becomes evidence. Its access inventory, logs, and decision records are things FedRAMP can ask to see.

Timeline and who it applies to

FedRAMP's rules are evolving, so treat the dates below as a planning guide and confirm current text on fedramp.gov.

Milestone	What happened or is expected
2025	FedRAMP publishes the 20x Authorization Data Sharing standard and pilots trust centers with 20x participants
July 4, 2026	The Consolidated Rules for 2026 take effect, carrying trust center rules into Certification Data Sharing
After January 1, 2027	Enforcement of the Consolidated Rules begins
Through 2027	FedRAMP has described a transition for Rev5 providers toward FedRAMP-compatible trust centers

Who should act now:

• 20x participants and applicants. The trust center is already part of your path. Build it alongside your KSI evidence.
• Rev5 providers with existing authorizations. Plan the move before your transition deadline, and use the time to automate continuous monitoring data so the trust center does not become a second manual process.
• Providers planning a first FedRAMP effort. Design the trust center into your program from day one. Retrofitting access logging and APIs later is harder than building them in.
• Providers selling to state and local government. Programs such as GovRAMP often follow FedRAMP's lead. A FedRAMP-grade trust center also answers many state buyer questions.

---

Who uses your trust center, and what they need

A FedRAMP-compatible trust center serves several audiences at once. Designing for each one keeps you from building a page that satisfies one reviewer and frustrates the rest.

Audience	What they are trying to do	What they need from you
FedRAMP	Confirm you meet the rules and monitor your offering over time	Access inventory, access logs, denied request reports, current certification data
Agency ISSO or security reviewer	Decide whether to accept the risk of using your service	Current package or 20x materials, KSI results, open plan of action items, scan summaries
Agency Authorizing Official	Sign an authority to operate or reuse decision	A clear summary of risk posture and status, without wading through raw data
Agency GRC tools	Pull data into the agency's own risk system automatically	Documented API, stable machine-readable formats, authentication for services
Assessors and advisors	Review evidence on behalf of an agency or the provider	Scoped, time-bound access to specific artifacts
Commercial buyers	Complete vendor due diligence	SOC 2 or ISO 27001 reports, policies, subprocessors, security FAQ

Most providers serve commercial buyers and agencies from one trust center with tiered access, rather than running two. That keeps content consistent and avoids the "which version is current?" problem.

---

The requirements, one by one

FedRAMP's rule identifiers have shifted as drafts moved into the Consolidated Rules for 2026 (for example, FRR-ADS and FRR-ADS-TC in the 20x standard, and CDS and CDS-TRC in later material). The substance has stayed consistent. For each requirement below you will find what the rule asks, what good looks like, common pitfalls, and the evidence you should be able to produce.

1. Be visible and clearly labeled (MUST)

What the rule asks. The trust center must be easy to find from your main website, and must clearly state that it contains FedRAMP materials.

What good looks like.

• A link labeled "Trust Center" or "Security" in your main navigation or footer
• A FedRAMP section near the top of the trust center, with your offering name, certification status, and how agencies get access
• A stable URL, ideally on your own domain, that does not change when you switch tools

Common pitfalls. Burying the trust center behind a sales form, hosting it on an unbranded vendor URL that agencies cannot recognize, or listing FedRAMP only as a logo with no explanation of how to reach the data.

Evidence to keep. Screenshots of the navigation link and FedRAMP section, plus the URL history if it ever moves.

2. Publish public offering information (MUST)

What the rule asks. Publish current information about your offering in both human-readable and machine-readable form, and use automation to keep the two consistent. The information includes items such as the offering name and description, certification status, customer support details, and the availability status of the trust center itself.

What good looks like.

• A public page and a structured data file (for example, JSON) generated from the same source
• A visible "last updated" timestamp
• A link to a status page that covers the trust center

Common pitfalls. Maintaining the web page and the data file by hand, so they drift apart. Forgetting that the trust center's own availability is part of what you publish.

Evidence to keep. The generation process (for example, the pipeline or platform setting that produces both formats) and a history of published versions.

3. Share responsibly (MUST)

What the rule asks. Include enough detail for agencies to make informed risk decisions, while leaving out details that would help a threat actor.

What good looks like.

• Every artifact classified into an access tier before it is published
• Sensitive details such as internal hostnames, IP ranges, and exact unpatched software versions limited to approved agency users, or summarized
• A short internal standard explaining how you decide what goes in which tier

Common pitfalls. Treating "responsible" as "share as little as possible." Agencies still need enough to decide. Equally risky is publishing a full SSP publicly because it was the quickest way to meet a deadline.

Evidence to keep. Your classification standard and the access tier of each artifact.

4. Offer human and machine-readable formats (SHOULD)

What the rule asks. Let authorized parties both view and download certification data in human-readable and machine-readable formats.

What good looks like.

• Readable web views for people, with download options
• Structured files for tools, in the formats FedRAMP specifies for your path. FedRAMP's 2026 direction favors simplified JSON documents, with OSCAL still relevant in some cases, such as higher-impact Rev5 packages.

Common pitfalls. Treating a PDF as machine-readable, or exporting a spreadsheet once and calling it a feed.

Evidence to keep. Examples of each format and the process that keeps them current.

5. Provide documented programmatic access (MUST)

What the rule asks. Provide documented programmatic access to all certification data, including the human-readable materials.

What good looks like.

• Published API documentation that an agency engineer can follow without a call
• Authentication suitable for both people and services, such as API keys or tokens scoped per agency
• Endpoints for listing and retrieving every artifact, with stable identifiers and version information
• Programmatic access governed by the same tiers, approvals, and logging as the web interface

Common pitfalls. An API that covers the machine-readable files but not the human-readable documents. Undocumented endpoints that only your own front end uses. Service accounts that bypass access logging.

Evidence to keep. The API documentation, authentication model, and logs showing programmatic access is recorded like any other access.

6. Support self-service access management (SHOULD)

What the rule asks. Include features that let necessary parties provision and manage access for their own users and services directly.

What good looks like.

• Agencies request access without emailing your team
• Once an agency is approved, it can add reviewers or service accounts within the scope you approved
• Access can be revoked, and expires when it is no longer needed

Common pitfalls. Requiring a manual ticket for every new reviewer, which creates delays and pushes agencies to share credentials.

Evidence to keep. The request and provisioning workflow, and records of access changes.

7. Maintain an inventory and history of agency access (MUST)

What the rule asks. Keep an inventory and history of federal agency users or systems with access to certification data, and make it available to FedRAMP on request.

What good looks like.

• A current list of every agency user and service with access, their agency, what they can reach, and when access started
• A history that shows past access, including who approved it and when it ended
• An export you can hand to FedRAMP the same day it is requested

Common pitfalls. Access spread across email threads, shared folders, and a portal, with no single record. Deleting records when access ends, which destroys the history.

Evidence to keep. The inventory itself, plus exports provided to FedRAMP.

8. Log access and keep summaries (MUST)

What the rule asks. Log access to certification data and store summaries of access for at least six months, with party-specific detail available on request. FedRAMP's guidance notes that authenticated access should be logged with the user and time, while anonymous access can be logged with the source IP address and time.

What good looks like.

• Logs for views, downloads, and API calls, across every tier
• Summaries per artifact and per party, retained for at least six months
• Logs protected from tampering, and reviewed for unusual access patterns

Common pitfalls. Logging downloads but not views, or the web interface but not the API. Short default retention in a logging tool that silently drops data after 30 or 90 days.

Evidence to keep. The logs, the summaries, and the retention configuration.

9. Report denied agency requests (MUST)

What the rule asks. Under the Consolidated Rules for 2026, notify FedRAMP within five business days when you deny an agency's request for access to certification data.

What good looks like.

• Every decision recorded with who decided, when, and why
• A defined owner who reports denials to FedRAMP
• A reminder or workflow so the five-day window is never missed

Common pitfalls. Letting requests sit undecided indefinitely, which is a denial in practice. Rejecting a request informally by email with no record.

Evidence to keep. Decision records and copies of notifications sent to FedRAMP.

Reference architecture

A FedRAMP-compatible trust center has more moving parts than a commercial security page. Thinking about it in layers keeps the design clean.

Layer	Purpose	Key capabilities
Source of truth	Where certification data is produced	GRC platform, control library, continuous monitoring, scan tools, POA&M tracking
Content and classification	Decides what is published and to whom	Artifact catalog, access tiers, versioning, review and approval before publishing
Access control	Decides who can see what	Identity for people and services, request and approval workflow, NDA acceptance, expiry and revocation
Delivery	Serves content to people and machines	Web views, downloads, documented API, machine-readable files
Accountability	Proves who saw what	Access logs, six-month summaries, agency inventory, decision records, denial reporting
Operations	Keeps it running	Availability monitoring, status page, update notifications, incident communication

A three-tier access model

Most providers land on three tiers. The names vary, but the logic is consistent.

Tier	Who can access	Typical content
Public	Anyone	Offering description, certification status, public offering data file, security overview, subprocessors, high-level controls, FAQ, trust center status
Registered	Verified agency users and services after a lightweight request	KSI summaries, continuous monitoring summaries, policies, customer responsibility guidance
Approved	Specific agency users after explicit approval, often with an NDA	Full package or 20x materials, detailed scan results, open plan of action items, incident reports

Every tier is logged. Public access is logged by source IP and time, and authenticated access by user and time.

How an agency request flows

1. An agency reviewer finds your trust center from your homepage and reads the public FedRAMP section.
2. They request access to the specific artifacts they need, identifying their agency.
3. Your team reviews the request, confirms the requester is legitimate, and the requester accepts your NDA if required.
4. You approve, and the decision is recorded with who approved and when. If you deny, the denial is recorded and reported to FedRAMP within five business days.
5. The reviewer views or downloads the artifacts. Their agency's GRC tool can pull the same data through the API.
6. Every view, download, and API call is logged, and the agency appears in your access inventory.
7. When new continuous monitoring data is published, subscribers are notified and the API returns the new version.
8. Access expires or is revoked when the engagement ends, and the history is kept.

What machine-readable looks like in practice

FedRAMP specifies formats for each path, and you should follow the official schemas when publishing. The examples below are illustrative only and show the kind of structure that makes a trust center easy for agency tools to consume. They are not FedRAMP schemas and not a SecureSlate API.

Public offering information

{
  "offering": {
    "name": "Example Cloud Platform",
    "provider": "Example Corp",
    "description": "Multi-tenant SaaS for case management",
    "certification": {
      "program": "FedRAMP",
      "path": "20x",
      "status": "Certified",
      "lastUpdated": "2026-10-01"
    }
  },
  "trustCenter": {
    "url": "https://trust.example.com",
    "statusUrl": "https://status.example.com",
    "apiDocumentation": "https://trust.example.com/docs/api"
  },
  "support": {
    "email": "federal-support@example.com",
    "hours": "24x7"
  }
}

The same source should generate the public web page, so the two never disagree.

An access log summary record

{
  "period": "2026-09",
  "artifact": "continuous-monitoring-summary-2026-09",
  "accessTier": "registered",
  "party": {
    "type": "federal-agency",
    "agency": "Example Agency",
    "subject": "service:example-agency-grc"
  },
  "views": 4,
  "downloads": 2,
  "apiRequests": 31,
  "firstAccess": "2026-09-03T14:12:00Z",
  "lastAccess": "2026-09-28T09:40:00Z"
}

Keep records like this for at least six months, and keep the underlying events so you can provide party-specific detail when FedRAMP asks.

What a good API covers

• List all certification data the caller is entitled to, with identifiers, titles, versions, and dates
• Retrieve each artifact in every format you publish, including the human-readable documents
• Show history so agency tools can see what changed since their last pull
• Authenticate people and services separately, with scopes that match your access tiers
• Log every call in the same access record as web activity

Commercial trust center vs. FedRAMP-compatible

If you already run a trust center for commercial sales, you have a head start. Here is where the gaps usually are.

Capability	Typical commercial trust center	FedRAMP-compatible trust center
Public security overview	Yes	Yes, with a clearly labeled FedRAMP section
Gated documents with NDA	Yes	Yes
Access approval workflow	Often	Required in practice, with decision records
Machine-readable public data	Rare	Required, kept consistent with the web page
Documented API for all data	Rare	Required
Agency user and service inventory	Rare	Required, with history
Access logs with six-month summaries	Varies	Required
Denied request reporting	Not applicable	Required within five business days
Availability published as data	Rare	Required
Update cadence	When marketing updates it	Tied to continuous monitoring

The pattern is clear: commercial trust centers optimize for conversion, FedRAMP-compatible trust centers optimize for accountability. You need both, and the good news is that one well-designed platform can do both.

Running the trust center day to day

The rules describe what the trust center must do. Meeting them consistently is an operational question.

Ownership

Activity	Responsible	Accountable	Consulted
Publishing certification data	Compliance or GRC lead	CISO	Engineering, legal
Classifying artifacts into tiers	Compliance lead	CISO	Security engineering, legal
Approving or denying access requests	Compliance lead or delegate	CISO	Federal sales
Reporting denials to FedRAMP	Compliance lead	CISO	Legal
API and availability	Platform engineering	Engineering leader	Compliance
Reviewing access logs	Security operations	CISO	Compliance
Updating public offering data	Compliance lead	CISO	Marketing, support

Service levels to set

• Access request decision: set an internal target well inside the five-business-day denial reporting window, so no request is ever left hanging. Many teams aim for one to two business days.
• Continuous monitoring updates: publish on the same cadence as your continuous monitoring reporting, so the trust center is never behind your reports.
• Trust center availability: monitor it like a production service, and publish its status.
• Incident communication: decide in advance how incident and significant change notices reach agencies through the trust center.

Monthly routine

1. Publish the latest continuous monitoring data and plan of action updates.
2. Confirm the public web page and data file match.
3. Review the access inventory and remove access that is no longer needed.
4. Review access logs for unusual patterns, such as bulk downloads or access from unexpected parties.
5. Confirm every access request from the month has a recorded decision, and every denial was reported.
6. Check that log summaries older than six months are still retained.

---

Ten mistakes to avoid

1. Treating the trust center as a marketing project. It is now part of your compliance obligations. Give it a compliance owner.
2. Maintaining two sources of truth. If the trust center content is copied by hand from your GRC system, it will drift. Generate it from the source.
3. Leaving requests undecided. An unanswered request is a denial in practice, and denials must be reported.
4. Logging the website but not the API. Programmatic access must be logged like everything else.
5. Relying on default log retention. Many tools keep logs for 30 or 90 days. FedRAMP expects summaries for at least six months.
6. Publishing too much publicly. A full SSP or detailed scan results in the public tier is a gift to attackers.
7. Publishing too little. Agencies still need enough detail to decide. Overly thin content just produces more access requests.
8. Forgetting service accounts. Agency GRC tools need their own identities, not shared human credentials.
9. Ignoring the trust center's own availability. It is part of your public information, and agencies notice when it is down.
10. Deleting history. When access ends, keep the record. FedRAMP asks for history, not just the current list.

How SecureSlate meets these requirements

SecureSlate's Trust Center is built into the same platform you use to run your FedRAMP program. The content it shares comes from your live controls, policies, and evidence, rather than from a separate spreadsheet that someone has to remember to update. Here is how it maps to each part of the architecture above.

Source of truth: continuous monitoring mapped to FedRAMP 20x

A trust center is only as good as the data behind it. SecureSlate keeps that data current:

• Cloud findings mapped to FedRAMP 20x Key Security Indicators, alongside SOC 2, ISO 27001, and other frameworks, so KSI evidence comes from live checks rather than screenshots.
• Automated control tests and evidence collection across 200+ integrations, giving you current continuous monitoring material to publish.
• Policies, risk registers, vendor risk, and audit workflows in one platform, so your package, plan of action items, and trust center tell the same story.
• One control library mapped across frameworks, so FedRAMP work also strengthens your SOC 2, ISO 27001, and CMMC posture.

Visibility: a branded home for FedRAMP materials

• Hosted trust center on your own domain. Publish on a SecureSlate-hosted page, or connect a custom domain such as trust.yourcompany.com, verified through DNS, so the trust center lives where agencies expect it.
• Framework status at a glance. Show FedRAMP alongside SOC 2, ISO 27001, CMMC, and others, each marked Compliant or Ongoing.
• Header, description, and links that state plainly that the trust center contains FedRAMP materials, and link to your main site, privacy policy, and support contacts.

Public information: current by default

• Public documents and policies, published with one setting per item.
• Security controls drawn from your SecureSlate control library and grouped by category, so the public view reflects how you actually operate.
• Subprocessors with hosting regions, which matters to agencies asking where federal data is processed.
• FAQ, with AI-assisted drafting from your existing program data, so answers stay consistent with your policies.
• Trust updates with confirmed subscribers. Post security and continuous monitoring updates and notify subscribers by email. Public sign-ups confirm their address first, so updates only reach people who asked for them.

Responsible sharing: tiers you control per item

• Public or Restricted, per policy and document. For restricted items, file links stay on the server until access is approved, so a copied link cannot expose your package.
• NDA and MSA acceptance before restricted access is granted.
• Role-based access for your own team, controlling who can publish content and who can approve requests.

Access control: a request workflow with a paper trail

• Request access per resource. Agency reviewers request the specific documents they need, without emailing your team.
• Every request is recorded with the requester's name, email, organization, and the resources requested.
• Clear statuses: each request is Needs Decision, Approved, or Rejected, so nothing gets lost in an inbox.
• CRM visibility. With the Salesforce integration, access requests and approvals sit next to the opportunity, so federal sales and security share one view.

Accountability: records you can show FedRAMP

• Recorded decisions. Every approval or rejection stores who made the decision and when. That gives you a history of which agency users were granted which documents.
• Denials ready to report. Rejected requests are recorded with the decision maker and date, so you can report them to FedRAMP inside the five-business-day window.
• A request queue you can work daily. Requests that still need a decision are visible in one place, which helps you hit your internal response target.

Walkthrough: an agency request in SecureSlate

1. The agency reviewer opens trust.yourcompany.com, sees FedRAMP marked with its status, and reads your public overview, controls, and subprocessors.
2. They click Request Access, choose the restricted documents they need, enter their details, and accept your NDA.
3. The request appears in SecureSlate as Needs Decision, and in Salesforce next to the opportunity.
4. Your compliance lead reviews it and approves. SecureSlate records who approved and when.
5. The reviewer receives access to the approved documents. Restricted file links were never exposed before this point.
6. Next month, you publish a new continuous monitoring update. Subscribers are notified by email.

What to confirm for your offering

FedRAMP's trust center rules are new, and several of them go beyond what commercial trust centers were built for: documented API access to all certification data, machine-readable data kept consistent with the web page, self-service management of agency users and services, and access logs with six months of retained summaries. When you evaluate any trust center, SecureSlate included, ask for a walkthrough of exactly how each of these is handled for your path, impact level, and certification class. Our team will map your FedRAMP path against these rules during onboarding and show you where the SecureSlate Trust Center covers each one today.

Mapping summary

A 90-day rollout plan

You do not need to do everything at once. This plan gets a FedRAMP-ready trust center live in a quarter.

Days 1 to 30: foundation

• Inventory your certification data: package or 20x materials, KSI results, scan reports, plan of action items, incident and change notices.
• Write a one-page classification standard and assign every artifact to a tier.
• Choose your trust center platform and domain, and add the trust center to your main website.
• Assign owners for publishing, access decisions, denial reporting, and availability.
• Connect your cloud and identity integrations so continuous monitoring data flows automatically.

Days 31 to 60: access and accountability

• Publish public content: offering overview, FedRAMP status, controls, subprocessors, FAQ.
• Upload restricted artifacts and require NDA acceptance where needed.
• Turn on the access request workflow and set an internal decision target.
• Confirm how access is logged and retained, and how you will export the agency inventory for FedRAMP.
• Write the procedure for reporting denials within five business days.

Days 61 to 90: automation and rehearsal

• Confirm your machine-readable and API approach for your path, and publish API documentation.
• Connect monthly continuous monitoring publishing to the trust center, with subscriber notifications.
• Run a tabletop: a mock agency requests access, you approve one request and deny another, and you produce the inventory, logs, and denial report.
• Add the trust center to your availability monitoring and status page.
• Start the monthly routine from the operating model above.

Questions to ask any trust center vendor

Use these in any evaluation, including ours.

1. How do you support FedRAMP's requirement for documented programmatic access to all certification data, including human-readable documents?
2. Which machine-readable formats do you support, and how do you keep them consistent with the web view?
3. Can agencies provision and manage their own users and service accounts after approval?
4. How is access logged for views, downloads, and API calls? Is anonymous public access logged by IP and time?
5. How long are access logs and summaries retained, and can retention be set to at least six months?
6. Can I export a full inventory and history of agency users and systems with access?
7. How are access decisions recorded, and how do you help me report denials within five business days?
8. Are restricted file links protected from being shared or reused outside approved access?
9. Can I host the trust center on my own domain?

Metrics that show it is working

Track a handful of measures so you know the trust center is doing its job, and can show it.

Metric	Why it matters
Median time to decide an access request	Shows agencies are not waiting, and keeps you clear of the denial reporting window
Requests older than your target	Early warning before a request becomes a reporting issue
Days since last certification data update	Shows the trust center is keeping pace with continuous monitoring
Web page and data file mismatches	Should be zero if both come from one source
Agency users and services with active access	Tracks reuse of your certification across agencies
Stale access (no use in 90 days)	Candidates for revocation, keeping the inventory tight
Trust center availability	Part of your public information, and a signal of reliability
Sales cycles shortened by self-service access	Connects the trust center to revenue

FAQ

Is a FedRAMP-compatible trust center required?

For FedRAMP 20x offerings, yes. The Authorization Data Sharing standard requires providers to use a FedRAMP-compatible trust center. Rev5 providers have historically used the USDA Connect Community Portal, and FedRAMP has signaled a transition to trust centers for them too. Check the current rules on fedramp.gov for your certification class.

Is a commercial trust center the same as a FedRAMP-compatible one?

Not automatically. A commercial trust center typically focuses on sharing SOC 2 reports and policies with buyers. A FedRAMP-compatible trust center adds documented programmatic access, machine-readable data, an inventory of agency users and systems, access logging with retention, and reporting of denied agency requests.

What counts as certification data?

The information that supports your FedRAMP certification and ongoing monitoring: your security package or 20x materials, Key Security Indicator results, vulnerability and continuous monitoring reports, plans of action, and incident and significant change communications.

How long must trust center access logs be kept?

FedRAMP's rules require trust centers to store summaries of access for at least six months, with party-specific detail available on request.

Do I have to log access to public content?

Yes. FedRAMP's guidance says anonymous access can be logged with the source IP address and time of access, while authenticated access should be logged with the user and time.

What happens if I deny an agency's access request?

Under the Consolidated Rules for 2026, you must notify FedRAMP within five business days of denying an agency's request for certification data. Record every decision so the report is easy to produce.

Can I put my full SSP on the public tier to keep things simple?

You should not. FedRAMP asks providers to share enough for agencies to decide, without exposing details that would help a threat actor. Detailed package content belongs in a restricted or approved tier.

Is OSCAL required?

It depends on your path. FedRAMP's 2026 direction favors simplified JSON documents, with OSCAL still relevant in some cases, such as higher-impact Rev5 packages. Follow the formats FedRAMP specifies for your certification class.

Can I use one trust center for FedRAMP and commercial customers?

Yes. Many providers run a single trust center with tiered access, so commercial buyers and agency reviewers each see what they are entitled to, and content stays consistent.

Does SecureSlate support FedRAMP 20x?

Yes. SecureSlate supports FedRAMP readiness and continuous monitoring, including cloud findings mapped to FedRAMP 20x Key Security Indicators. See FedRAMP compliance with SecureSlate.

How long does it take to launch a FedRAMP-ready trust center?

With your certification data inventoried and a platform in place, most teams can follow a plan like the 90-day rollout above. The hardest parts are usually classification decisions and automating continuous monitoring data, not the page itself.
