SOC 2 Type II and ISO 27001 Engineering Readiness Checklist for SaaS
Technical implementation roadmap for passing SOC 2 Type II and ISO/IEC 27001 audits: infrastructure evidence collection, CI/CD controls, and IAM automation.
For B2B SaaS companies, achieving **SOC 2 Type II** and **ISO/IEC 27001** certification is no longer an optional security milestone; it is an absolute requirement for passing enterprise vendor security assessments and unlocking five
and six-figure enterprise contracts.
Unlike SOC 2 Type I (which assesses security controls at a single static point in time), SOC 2 Type II audits operational effectiveness over a continuous **3 to 12 month monitoring window**.
2. Core Technical Control Domains
To achieve audit readiness without derailing product engineering roadmaps, focus implementation efforts on the following technical domains:
Domain 1: Identity and Access Management (IAM)
Enforce mandatory Single Sign-On (SSO) with FIDO2/WebAuthn Hardware MFA across all corporate and cloud accounts.
Prohibit long-lived AWS IAM secret keys; enforce dynamic, short-lived AWS IAM roles via OpenID Connect (OIDC) from GitHub Actions.
Conduct automated quarterly user access reviews and maintain cryptographic access log trails.
Domain 2: Infrastructure as Code & Change Management
Enforce mandatory branch protection rules on `main` and `master` repositories.
Require at least one peer code review approval and clean static analysis security scans before deployment.
Maintain immutable production release audit logs linking Git commit SHAs directly to deployed container image digests.
Domain 3: Encryption at Rest and in Transit
Mandate TLS 1.3 for all external HTTP traffic and internal service-to-service service mesh communications.
Enable AWS KMS or Azure Key Vault Customer Managed Keys (CMK) with automated annual cryptographic key rotation for all storage volumes and databases.
3. Continuous Compliance Automation Tooling
Modern engineering organizations should avoid manual screenshot-based audits in favor of continuous automated compliance platforms (such as Vanta, Drata, or Secureframe). These tools integrate directly with AWS, GitHub, Google Workspace, and Jira to monitor compliance state continuously and flag configuration drift within minutes.
