SOC 2 Compliance for Seed-Stage Startups: The 90-Day Roadmap

TL;DR

SOC 2 Type I in 90 days is achievable for seed-stage startups. The secret: automate evidence collection from day one, pick a compliance platform that does 80% of the work, and focus on the five Trust Service Criteria that actually matter. Skip the $200K consulting engagement. Total cost: ~$15-25K for platform + auditor. Engineering time: 2-4 weeks of focused effort.

Part of the SaaS Architecture Decision Framework ... a comprehensive guide to architecture decisions from MVP to scale.


Why SOC 2 Now

Enterprise sales pipelines die in security questionnaires. I've watched startups with great products lose six-figure deals because they couldn't answer "Are you SOC 2 compliant?" with a yes.

The math is simple:

  • Average enterprise deal: $50-200K ARR
  • Average security questionnaire: 300-500 questions
  • Time to answer without SOC 2: 20-40 hours per questionnaire
  • Time to answer with SOC 2: "Here's our report" (5 minutes)

More importantly, completing SOC 2 forces you to build security infrastructure you'll need anyway. The compliance deadline becomes the accountability mechanism for doing things right.


Type I vs Type II: Start with Type I

Type I: Point-in-time assessment. "Your controls exist as of this date."

Type II: Period assessment. "Your controls existed and operated effectively over 3-12 months."

Start with Type I. It proves you have controls in place. You can pursue Type II afterward with a 3-month observation window.

Enterprise buyers accept Type I reports, especially from startups. The conversation is: "We have Type I, Type II in progress, report expected [date]."


The Five Trust Service Criteria

SOC 2 has five categories. You only need Security for Type I. Add others if customers require them.

Security (Required)

The foundation. Covers:

  • Access control
  • System operations
  • Change management
  • Risk mitigation

This is the one you must get right. The others are optional.

Availability (Optional)

Uptime commitments. Add this if you have SLAs in customer contracts.

Covers:

  • System monitoring
  • Incident response
  • Disaster recovery
  • Capacity planning

Processing Integrity (Rare)

Data processing accuracy. Only needed if you process financial transactions or sensitive calculations.

Confidentiality (Common)

Data protection beyond security. Add if you handle trade secrets, financial data, or other confidential customer information.

Privacy (Situational)

Personal data handling. Overlaps with GDPR. Add if you process PII extensively.

Recommendation for seed-stage: Start with Security + Availability. Add Confidentiality if handling sensitive data. Skip Processing Integrity and Privacy unless required.


The 90-Day Roadmap

Weeks 1-2: Platform Selection and Gap Assessment

Day 1-3: Choose a compliance platform

Don't do this manually. The platforms automate evidence collection, policy generation, and auditor coordination.

PlatformStarting PriceStrengths
Vanta~$10K/yearBest integrations, fast setup
Drata~$12K/yearStrong automation, good UI
Secureframe~$8K/yearCost-effective, solid features
Laika~$15K/yearEnterprise-focused

I've worked with Vanta and Drata. Both integrate with AWS, GCP, GitHub, and major SaaS tools. They pull evidence automatically... no manual screenshot collection.

Day 4-7: Connect integrations

Wire up your infrastructure:

  • Cloud provider (AWS, GCP, Azure)
  • Version control (GitHub, GitLab)
  • Identity provider (Okta, Google Workspace)
  • HR system (Gusto, Rippling)
  • Endpoint management (Jamf, Kandji)
  • Monitoring (Datadog, PagerDuty)

The platform scans your environment and identifies gaps.

Day 8-14: Review gap report

The platform generates a gap assessment. Typical findings for startups:

  • No formal access reviews
  • No background checks policy
  • No security awareness training
  • No documented incident response
  • No encryption at rest (or not enforced)
  • No MFA on all systems

Prioritize by effort vs. impact. Some fixes are one-click. Others require engineering work.


Weeks 3-6: Control Implementation

Access Control

// Example: Role-based access with audit logging interface AccessRequest { userId: string; resource: string; action: "read" | "write" | "delete"; timestamp: Date; granted: boolean; reason?: string; } async function checkAccess(request: AccessRequest): Promise<boolean> { const user = await getUser(request.userId); const permissions = await getPermissions(user.role); const granted = permissions.includes(`${request.resource}:${request.action}`); // Log every access decision for audit trail await logAccessDecision({ ...request, granted, userRole: user.role, }); return granted; }

Key requirements:

  • Unique user accounts: No shared credentials
  • MFA everywhere: All production systems, all admin access
  • Principle of least privilege: Start with no access, add as needed
  • Access reviews: Quarterly review of who has access to what
  • Offboarding procedure: Revoke access within 24 hours of termination

Encryption

  • At rest: Enable encryption on all databases, object storage, backups
  • In transit: TLS 1.2+ everywhere, no exceptions
  • Key management: Use cloud KMS, rotate annually

For AWS:

# Enable default encryption on S3 aws s3api put-bucket-encryption \ --bucket my-bucket \ --server-side-encryption-configuration '{"Rules":[{"ApplyServerSideEncryptionByDefault":{"SSEAlgorithm":"aws:kms"}}]}' # Enable RDS encryption (must be set at creation) aws rds create-db-instance \ --storage-encrypted \ --kms-key-id alias/aws/rds \ ...

Logging and Monitoring

  • Centralized logging (CloudWatch, Datadog, Splunk)
  • Log retention: 1 year minimum
  • Alerting on security events
  • Audit trail immutability
// Example: Immutable audit log structure interface AuditEvent { id: string; timestamp: Date; actor: { userId: string; ipAddress: string; userAgent: string; }; action: string; resource: string; outcome: "success" | "failure"; metadata: Record<string, unknown>; // Tamper detection previousHash: string; hash: string; } function hashEvent(event: Omit<AuditEvent, "hash">): string { return crypto.createHash("sha256").update(JSON.stringify(event)).digest("hex"); }

Change Management

  • All changes through pull requests
  • Required reviews (at least one)
  • CI/CD pipeline with automated tests
  • No direct production access (except break-glass)

Your GitHub settings should include:

  • Branch protection on main
  • Required reviews before merge
  • Status checks must pass
  • No force push

Weeks 7-8: Policy Documentation

The compliance platform generates policy templates. Customize them for your organization.

Required policies (at minimum):

  1. Information Security Policy
  2. Access Control Policy
  3. Change Management Policy
  4. Incident Response Plan
  5. Risk Assessment Procedure
  6. Vendor Management Policy
  7. Data Classification Policy
  8. Acceptable Use Policy
  9. Business Continuity Plan
  10. Password Policy

Don't overthink it. The auditor wants to see that policies exist and are followed. A 2-page policy that's actually enforced beats a 50-page policy nobody reads.

Example policy structure:

# Access Control Policy ## Purpose Define requirements for granting, reviewing, and revoking access. ## Scope All employees and contractors accessing company systems. ## Policy 1. Access granted based on job function (least privilege) 2. All accounts require MFA 3. Access reviewed quarterly by department heads 4. Access revoked within 24 hours of termination 5. Shared accounts prohibited ## Exceptions Emergency break-glass procedures documented in Incident Response Plan. ## Review Annually by Security Lead.

Week 9-10: Evidence Collection and Testing

Automated evidence

Your compliance platform collects most evidence automatically:

  • User access lists
  • MFA enforcement status
  • Encryption configuration
  • Vulnerability scan results
  • Deployment logs
  • Background check completion

Manual evidence

Some evidence requires human action:

  • Security awareness training completion (use a tool like KnowBe4)
  • Access review sign-offs
  • Risk assessment documentation
  • Vendor security reviews
  • Board/management security briefings

Control testing

Before the auditor arrives, test your controls yourself:

  1. Can you create a user without MFA? (Should fail)
  2. Can you merge code without a review? (Should fail)
  3. Can you access production data directly? (Should fail, or be logged)
  4. Can you deploy without passing CI? (Should fail)
  5. Are old user accounts disabled? (Should be)

Fix anything that fails before the audit.


Weeks 11-12: Auditor Engagement

Selecting an auditor

The Big 4 cost $150K+. Don't do that.

Startup-friendly auditors:

AuditorTypical CostNotes
Johanson Group$8-15KFast, startup-focused
A-LIGN$15-25KSolid reputation
Coalfire$20-30KMore enterprise
Prescient Assurance$10-18KGood for first audit

Your compliance platform usually has preferred auditors with discounted rates.

The audit process

  1. Planning call: Scope, timeline, evidence requirements
  2. Evidence submission: Upload through platform or secure portal
  3. Walkthroughs: Video calls to demonstrate controls
  4. Testing: Auditor samples evidence and tests controls
  5. Findings: Any gaps identified
  6. Remediation: Fix findings (usually minor)
  7. Report issuance: Final SOC 2 Type I report

Total auditor time: 2-4 weeks from kickoff to report.

  • Deployment approval process
  • Break-glass procedure documented

People

  • Background checks for all employees
  • Security awareness training completed

Common Pitfalls

1. Starting too early with Type II

Type II requires a 3-12 month observation period. If you're not ready, you're just paying for audit time while you fix things.

Get Type I first. It proves you're serious. Then run controls for 3 months and get Type II.

2. Over-documenting

I've seen startups write 100-page policies that nobody follows. The auditor will ask "how do you enforce this?"

Short, enforceable policies beat comprehensive, ignored ones.

3. Manual evidence collection

If you're taking screenshots manually, you're doing it wrong. Every hour spent on manual evidence is an hour not spent building product.

The compliance platforms pay for themselves in time saved.

4. Waiting for the "right time"

There's no right time. You'll always have higher priorities. The enterprise deal you lose because you don't have SOC 2 is the real cost.

Pick a date 90 days out. Work backward from there.

5. Treating it as a checkbox

SOC 2 isn't a one-time event. It's an annual audit. Build sustainable processes, not temporary fixes.


Cost Breakdown

For a 10-person seed-stage startup:

ItemCost
Compliance platform (annual)$8-15K
Auditor (Type I)$10-20K
Security awareness training$500-2K
Background checks$50-100/person
Endpoint management$5-10/device/month
Total Year 1$20-40K

Engineering time: 80-160 hours (2-4 weeks of one engineer's focused time)

Compare to the alternative:

  • Losing a $100K enterprise deal: Priceless
  • 300-question security questionnaire: 30 hours per prospect
  • DIY compliance without platform: 6-12 months

The ROI is obvious if you're selling to enterprises.


After Type I: The Path to Type II

Once you have Type I:

  1. Continue operating controls for 3-6 months
  2. Platform collects continuous evidence
  3. Schedule Type II audit
  4. Auditor reviews the observation period
  5. Report covers "controls operated effectively from [date] to [date]"

Type II is the gold standard. Most enterprises want to see it within your first year of engagement.


The Real Benefit

SOC 2 forces you to build infrastructure you need anyway:

  • Proper access control (you should have this)
  • Centralized logging (you'll need it for debugging)
  • Change management (you'll need it for reliability)
  • Incident response (you'll need it when things break)

The compliance deadline is just the forcing function. The real value is building a secure, well-operated system.


Planning your SOC 2 journey? I help startups build compliant infrastructure from the ground up... or retrofit existing systems for compliance without the six-month enterprise consulting engagement. The key is automating evidence collection from day one and building security into your architecture, not bolting it on later.
