Building an endpoint security baseline for startups
An endpoint security baseline is the fastest way for startups to look credible in enterprise security reviews—and avoid rebuilding device management under audit pressure. You do not need a 200-page security program on day one. You need five enforced checks on every laptop, MDM enrollment before production access, and continuous proof that controls are working.
This guide covers:
- Why startups should implement endpoint baseline before the first SOC 2 or ISO 27001 audit
- Five core checks: HD encryption, anti-virus, password policy, screen policy, and firewall
- A week-one implementation plan for teams of 5–50 people
- MDM selection criteria for small teams
- How SecureSlate Asset Management turns enforcement into audit-ready evidence

Key takeaways
- Five checks, one baseline — encryption, anti-virus, password policy, screen policy, firewall on every in-scope device.
- MDM enforces; SecureSlate proves — configuration profiles push settings; Asset Management tracks 5/5 pass status for audits.
- Enroll before production access — no exceptions for founders, early engineers, or "just this one contractor."
- Week one is enough to start — perfect is the enemy of enrolled; iterate profiles after visibility exists.
- Enterprise deals ask for evidence — a 5/5 dashboard answers DDQ questions before the security review call.
Why startups need a baseline now
Startups delay endpoint security because headcount is small and audits feel far away. Then a Series B lead or enterprise pilot triggers a 200-question security review—and the team spends six weeks scrambling.
Common triggers that expose endpoint gaps:
- First SOC 2 Type II observation window starting
- Enterprise customer security questionnaire (SIG Lite, CAIQ, or custom DDQ)
- ISO 27001 certification for EU market entry
- Investor due diligence before a funding round
- Cyber insurance application requiring device management evidence
A baseline implemented at 15 employees takes one week. The same program rebuilt at 80 employees during audit prep takes two months and generates findings on devices that operated unmanaged for a year.
The five-check baseline
SecureSlate Asset Management monitors five checks that map to virtually every framework's endpoint requirements:
| # | Check | Startup minimum | Why auditors care |
|---|---|---|---|
| 1 | HD Encryption | FileVault (Mac) / BitLocker (Windows) enabled | Lost laptop ≠ data breach |
| 2 | Anti-Virus | Approved EDR/AV agent installed and running | Malware protection on endpoints |
| 3 | Password Policy | ≥12 characters; lockout after failed attempts | Stolen device credential resistance |
| 4 | Screen Policy | Auto-lock ≤5 minutes; password required to unlock | Unattended device exposure window |
| 5 | Firewall | Host firewall enabled; user cannot disable | Network attack surface reduction |
Target: 5/5 on every enrolled device. SecureSlate shows pass/fail per check so you fix gaps before an auditor samples your worst laptop.
Choosing MDM for a small team
Startups typically choose MDM based on fleet composition and existing stack:
| Factor | Apple-heavy team | Mixed Mac + Windows | Microsoft 365 shop |
|---|---|---|---|
| Common choice | Jamf, Kandji | Kandji, Hexnode, Intune | Intune |
| Setup time | 1–2 days | 2–3 days | 1–2 days (if M365 licensed) |
| Cost driver | Per-device pricing | Per-device pricing | Often included in M365 |
| SecureSlate integration | Supported MDM connectors | Supported MDM connectors | Supported MDM connectors |
Pick one MDM and enroll every device. Running two MDMs at 20 people creates confusion; running zero MDMs creates audit findings.
For program design beyond tool selection, see the MDM compliance guide.
Week-one implementation plan
Day 1–2: Inventory and policy
- List every laptop/phone with company data access (include founders and contractors).
- Draft a one-page endpoint security standard referencing the five checks.
- Choose MDM; create admin account.
Day 3–4: MDM profiles
- Deploy encryption enforcement profile.
- Deploy AV/EDR requirement (or bundle with your chosen agent).
- Deploy password policy (≥12 chars, max failed attempts).
- Deploy screen lock (≤5 min idle timeout).
- Deploy firewall profile (enabled, locked).
Day 5: Enrollment blitz
- Enroll all company-owned devices—schedule 30-minute slots if needed.
- Gate IdP / email access on MDM compliance where supported.
- Document any exceptions with risk acceptance and expiry date.
Day 6–7: SecureSlate connection
- Connect MDM to SecureSlate Asset Management.
- Verify 5/5 dashboard populates for enrolled devices.
- Remediate any device below 5/5 checks.
- Export baseline report for your records.
One week later you have a defensible baseline—not a perfect program, but enrolled, enforced, and visible.
Baseline configuration reference
| Check | Mac (Apple) | Windows | MDM profile type |
|---|---|---|---|
| HD Encryption | FileVault required | BitLocker required | Disk encryption / compliance policy |
| Anti-Virus | Approved EDR agent | Approved EDR agent | App requirement / compliance check |
| Password Policy | ≥12 chars; 10 max failures | ≥12 chars; lockout threshold | Passcode / password policy |
| Screen Policy | Lock ≤5 min; passcode to wake | Lock ≤5 min; password to wake | Screen saver / idle timeout |
| Firewall | Application firewall enabled | Windows Defender Firewall on | Firewall configuration profile |
Adjust values to match your written policy—auditors compare all three layers (policy, MDM, SecureSlate).
From baseline to audit-ready
| Milestone | What you have | What to add |
|---|---|---|
| Week 1 | 5/5 baseline on enrolled devices | Nothing—ship it |
| Month 1 | SecureSlate weekly monitoring cadence | Offboarding tied to MDM removal |
| Month 2–3 | Policy approved; control mapping started | HR onboarding requires enrollment |
| Month 3–6 | Continuous evidence for Type II window | Internal mock audit sample |
| Audit season | Population export from SecureSlate | Device samples on request |
Startups pursuing SOC 2 should read MDM for SOC 2 Type II endpoint evidence. ISO 27001 teams should see MDM for ISO 27001 endpoint controls.
If you allow BYOD, add enrollment before personal devices get email access—BYOD and MDM.
Shortcuts that backfire
- "Founders are exempt" — auditors sample executive devices; unencrypted CEO laptop = finding.
- Spreadsheet device inventory — stale within weeks; use MDM enrollment as source of truth.
- Manual encryption checks — "I asked everyone in Slack" is not operating evidence.
- Deploy MDM but skip SecureSlate — you can enforce but cannot prove continuous compliance.
- Wait until SOC 2 scoping call — Type II observation windows need months of history you do not have yet.
Scaling the program
As headcount grows from 20 to 200:
| Growth stage | Endpoint focus |
|---|---|
| 20–50 employees | Automate onboarding enrollment; weekly 5/5 review |
| 50–100 employees | Tiered policies (engineering vs sales); BYOD program if needed |
| 100–200 employees | Dedicated endpoint owner; integration with HRIS offboarding |
| 200+ employees | Separate COBO and BYOD populations; quarterly internal audit samples |
The five-check baseline does not change as you scale—only enrollment automation and ownership mature.
Prepare for incidents before they happen: lost laptop playbook.

FAQ: Startup endpoint baseline
How many employees before we need MDM?
If anyone accesses customer data or production systems on a laptop—now. Five-person teams lose devices too.
Can we pass SOC 2 with just the five checks?
Endpoint baseline covers a major slice of CC6.x/CC7.x evidence, but SOC 2 requires additional controls (access, monitoring, policies). SecureSlate supports the full program—not just endpoints.
What if we cannot afford a separate MDM?
Microsoft Intune may be included in existing M365 licensing. Jamf and Kandji offer startup-friendly tiers. Cost of one audit finding exceeds annual MDM fees.
Do contractors need the same baseline?
If contractors access company systems on their own devices—yes. Enroll via BYOD model or require company-owned hardware.
How long until SecureSlate shows 5/5 data?
After MDM connection and first sync—typically within 24 hours of enrollment.
Should we write a formal policy first or deploy MDM first?
Deploy MDM first for visibility; publish policy within the same week. Auditors want both, but enforcement without documentation beats documentation without enforcement.
Can we reuse this baseline for ISO 27001?
Yes—the five checks map to Annex A 8.x controls. See MDM for ISO 27001.
What is the biggest mistake startups make?
Delaying enrollment until audit prep—Type II needs months of continuous evidence you cannot backfill.
