SOC-2 Controls Library

SOC-2 Controls for Startups

A practical, copy-paste library of SOC-2 controls sized for solopreneurs and small teams (2-5 people). Pick what fits your stage, stack, and risk profile.

The SOC-2 Mental Model

Every control traces back through this hierarchy. Auditors walk this chain top-to-bottom to verify completeness.

1

Trust Services Criteria (TSC)

Why / Objectives. The five AICPA categories: Security (CC), Availability (A), Processing Integrity (PI), Confidentiality (C), Privacy (P). Security is always required; others are optional.

2

Policies

Rules / Intent. Board-level documents that state what the company commits to. "We will encrypt data at rest." Reviewed annually.

3

Controls

Testable Requirements. Specific, auditable statements that implement a policy. "All S3 buckets must have AES-256 encryption enabled." An auditor can verify pass/fail.

4

Procedures

Execution Steps. Step-by-step runbooks that people follow to satisfy controls. "Run aws s3api get-bucket-encryption quarterly and log output."

5

People & Roles

Ownership. Named individuals (not teams) responsible for each control. In a startup, one person often wears 3-4 hats.

6

Systems

Enforcement Layer. Tooling that automates or enforces the control: AWS Config rules, GitHub branch protection, MDM policies, SSO providers.

7

Evidence

Proof. Artifacts an auditor reviews: screenshots, logs, config exports, signed policy docs, ticket histories. Collected continuously, not scrambled before audit.

Trust Services Criteria

SOC-2 is organized around these five categories. Most startups begin with Security only, then add others as customers require them.

CC - Security

Protection against unauthorized access. Always in scope.

A - Availability

System uptime and disaster recovery commitments.

PI - Processing Integrity

Data processing is complete, accurate, timely.

C - Confidentiality

Protection of confidential information (NDA-level).

P - Privacy

PII collection, use, retention, and disposal practices.

Core Policies

These are the written documents your company commits to. Each policy spawns multiple controls. Start with the required ones.

How access to systems is granted, reviewed, and revoked. Principle of least privilege.

  • MFA enforcement rules

  • Quarterly access reviews
  • Maps to: CC6.1, CC6.2, CC6.3

Change Management Policy Required

How code and infrastructure changes are proposed, reviewed, approved, and deployed.

Acceptable Use Policy Recommended

Rules for employee use of company systems, devices, and data.

  • Approved software list

  • Data subject rights process
  • Retention schedules
  • Consent mechanisms
  • Maps to: P1.1, P1.2

People & Roles

In a startup, one person often fills multiple roles. What matters is that every control has a named owner. Here is a typical mapping for a 1-5 person team.
