Weighing other scanners? See our guide to vulnerability scanning tools and how pentesting differs from scanning.
The short version
SecureSlate and Intruder both scan what you expose to the internet and tell you what to fix. They start from different places. Intruder is a dedicated vulnerability scanner built to find weaknesses across your infrastructure, web applications, and cloud. SecureSlate is a compliance and security platform that includes scanning, then ties every finding to the controls and evidence your SOC 2 or ISO 27001 auditor will ask about.
- Choose SecureSlate if vulnerability scanning is one part of a compliance program you also need to run, and you would rather have scanning, code security, cloud posture, and audit evidence in one platform.
- Choose Intruder if you need deep network and infrastructure vulnerability scanning across many hosts, internal and external, and your compliance program already lives somewhere else.
- The honest split: SecureSlate covers the whole job around the scan, from finding to fix to audit evidence. Intruder goes deeper on infrastructure scanning. Below is the detail, including where Intruder wins.
How we compare these platforms
This comparison is published by SecureSlate, so read it with that in mind. To keep it useful, capability is rated in three states:
| Rating | What it means |
|---|---|
| 🟢 | Built in and usable without add-ons |
| 🟠 | Present but limited or partial, or dependent on tier or a separate module |
| 🔴 | Not available natively |
- Intruder gets credit where it earns it. Categories where Intruder is stronger are named in the tables and collected in one section.
- Pricing is directional. Verify both numbers against a written proposal covering the same targets, frameworks, and term.
- Claims map to documentation. SecureSlate capabilities link to product or documentation pages you can check.

If you only read one section, make it scanning depth or compliance, which is where the two products actually separate.
Vulnerability scanning depth
This is Intruder's home ground and it is worth saying plainly. Intruder scans servers, network devices, and cloud workloads for known vulnerabilities, misconfigurations, and exposed services, internally and externally. When a new high-profile CVE lands, a dedicated scanner like Intruder is built to check your estate for it quickly.
SecureSlate does not try to be a network vulnerability scanner. Its DAST and attack surface monitoring scans your live domains from the outside, starting with your primary domain the moment you sign up, and rescans on a recurring interval. It finds issues that only exist in a running application, such as error pages that disclose internal paths, missing or permissive security headers, weak content security policies, and source code or configuration served by the web server. Each finding carries a CWE, a severity, a confidence score, and a recommended solution.
If your audit scope includes a fleet of servers that need authenticated CVE scanning, SecureSlate alone will not cover it. If your risk sits mostly in a SaaS application and its cloud account, SecureSlate covers the surface most auditors and customers ask about.
| SecureSlate | Intruder | |
|---|---|---|
| Web application scanning from outside | 🟢 | 🟢 |
| CWE classification and confidence scores | 🟢 | 🟠 Severity and context |
| Known CVE checks on hosts and services | 🔴 | 🟢 |
| Internal network scanning | 🔴 | 🟢 |
| Recurring automatic rescans | 🟢 | 🟢 |
| On-demand scan after a release | 🟢 | 🟢 |
Attack surface and cloud coverage
Both products care about the assets you forgot. Intruder monitors your external attack surface for changes such as newly opened ports and services. SecureSlate discovers the subdomains sitting under any domain you monitor, so the forgotten staging host gets scanned like everything else.
On cloud, SecureSlate runs agentless, read-only cloud misconfiguration scanning across AWS, Azure, and GCP, using a read-only connection (AWS setup guide). Findings map to SOC 2 and ISO 27001 controls rather than sitting in a separate console. Intruder also connects to cloud accounts to keep targets in sync and run cloud security checks.
| SecureSlate | Intruder | |
|---|---|---|
| Subdomain discovery | 🟢 | 🟢 |
| Port and service change monitoring | 🔴 | 🟢 |
| Cloud misconfiguration checks | 🟢 AWS, Azure, GCP | 🟢 |
| Cloud findings mapped to compliance controls | 🟢 | 🔴 |
Code, secrets, and the rest of the stack
A vulnerability scanner looks at what is deployed. Many of the findings an auditor cares about start earlier, in the repository. SecureSlate includes code security and SAST across 30+ languages (supported languages), secrets detection, outdated and end-of-life software tracking, open source license risk, and dark web monitoring.
SecureSlate also acts on what it finds. The dependency vulnerability auto-remediation agent works on vulnerable packages, and the security issue SLA triage agent keeps findings moving against their deadlines. Intruder's focus is the scan itself, so confirm in a demo which code-level checks are included.

| Secrets detection | 🟢 | Confirm with Intruder |
| Dependency and end-of-life tracking | 🟢 | Confirm with Intruder |
| Dark web credential monitoring | 🟢 | 🔴 |
| Automated remediation agents | 🟢 | 🔴 |
Compliance and audit evidence
This is the category where the products diverge most. Most teams buy a scanner because SOC 2, ISO 27001, PCI DSS, or a customer questionnaire told them to. The scan is the evidence. The program around it is the work.
Intruder produces scan reports you can hand to an auditor, and it integrates with other tools to share results. You still need somewhere to hold policies, run access reviews, assess vendors, map controls, and organize evidence for fieldwork.
SecureSlate is that place. Scan findings land next to the controls they satisfy, alongside multi-framework control mapping, policies, access reviews, vendor risk, a trust center, and audit management. When the auditor asks how you identify and remediate technical vulnerabilities, the record of what was scanned, what was found, and what happened to it is already in the platform.
| SecureSlate | Intruder | |
|---|---|---|
| SOC 2, ISO 27001, HIPAA, GDPR frameworks | 🟢 | 🔴 |
| Scan results mapped to controls | 🟢 | 🔴 |
| Shareable scan reports | 🟢 | 🟢 |
| Policies, access reviews, vendor risk | 🟢 | 🔴 |
| Audit management and data room | 🟢 | 🔴 |
Pricing
Both vendors publish pricing, which makes this easier than most comparisons. Intruder prices its plans by the number of targets you scan, with tiers that add features such as authenticated web app scanning and broader attack surface coverage. Check Intruder's pricing page for current figures at your target count.
SecureSlate includes vulnerability scanners from the Pro plan at $4,788 per year, which also covers a compliance framework, automated control testing, risk management, and user access reviews. Ultra at $8,500 per year adds a penetration test and a framework audit. See the pricing page or model it with the savings calculator.
The fair way to compare is total cost. If you would buy Intruder and a compliance platform, add both. If you already own a GRC tool you like, compare Intruder against the scanning you actually need.
| SecureSlate | Intruder | |
|---|---|---|
| Published list pricing | 🟢 | 🟢 Entry tiers |
| Pricing basis | Plan and framework | Number of targets |
| Compliance program included | 🟢 | 🔴 |
| Penetration test option | 🟢 Included in Ultra | 🟠 Separate offering |
Where Intruder wins
Infrastructure scanning depth. Intruder scans hosts, services, and network devices for known vulnerabilities, internally and externally. SecureSlate does not. If servers and network gear are in scope, this alone may decide it.
Emerging threat response. A dedicated scanner is built to check your estate quickly when a new critical CVE is published. That is a real advantage for teams with a large, mixed infrastructure.
Focus. Intruder does one job and its interface is built around it. Security teams who want a scanner and nothing else will find less to configure.
Fits an existing GRC stack. If you already run a compliance platform you are happy with, Intruder can sit alongside it as the scanning layer.
Who each platform is for
Choose SecureSlate if
- You need SOC 2, ISO 27001, or HIPAA and want scanning to feed straight into that program.
- Your exposure is mostly a web application, its domains, its code, and its cloud account.
- You want code, secrets, cloud, and dark web findings in the same place as your controls.
- You would rather consolidate a scanner and a compliance tool into one contract.
Choose Intruder if
- You have many servers, network devices, or internal hosts that need CVE scanning.
- Fast checks for newly published vulnerabilities across your estate matter most.
- Your compliance program is already settled in another platform.
FAQ
Is SecureSlate an Intruder alternative?
For teams whose main exposure is a web application and its cloud account, and who need compliance as well, yes. SecureSlate covers DAST, attack surface discovery, cloud misconfiguration, and code security inside a compliance platform. For deep network and host vulnerability scanning, Intruder is the stronger tool.
Does SecureSlate do network vulnerability scanning like Intruder?
No. SecureSlate scans live domains and web applications from the outside, scans cloud accounts for misconfigurations, and scans code and dependencies. It does not run CVE scans against internal hosts or network devices.
Can I use Intruder and SecureSlate together?
Yes. Some teams run a dedicated infrastructure scanner and use SecureSlate for compliance, code security, and web application scanning. Upload Intruder reports to the SecureSlate data room so they sit next to the controls they support.
Which is cheaper, SecureSlate or Intruder?
It depends on what you are buying. Intruder alone may cost less than SecureSlate if you only need scanning. If you need a scanner and a compliance platform, SecureSlate Pro at $4,788 per year usually costs less than buying both separately. Compare written quotes for the same scope.
Is vulnerability scanning required for SOC 2?
SOC 2 does not name a specific tool, but auditors expect you to identify and remediate vulnerabilities in systems you expose. Scanning with a documented remediation record is the usual way to show it. See how often to scan.
Is this comparison biased?
It is published by SecureSlate, so treat it as a vendor's argument. We have tried to make it checkable: SecureSlate claims link to documentation, and the categories where Intruder is stronger are named in Where Intruder wins.
