ISO 27001 requires a functioning Information Security Management System, but most security violations originate in code. MergeGuide maps ISO 27001:2022 Annex A controls to code-level detection patterns, enforcing them at every point in the development workflow.
ISO 27001:2022 is an international standard for information security management. Its Annex A contains 93 controls organized across four themes: Organizational, People, Physical, and Technological. Software teams are primarily responsible for the Technological controls, and these are where most certification gaps are found.
Annex A controls like A.8.24 (cryptography), A.8.25 (secure development lifecycle), A.8.26 (application security requirements), and A.8.28 (secure coding) require demonstrable, repeatable processes, not one-time audits.
MergeGuide includes policies that guide implementation of ISO 27001:2022 requirements, mapping Annex A Technological controls to automated code-level detection patterns that run on every commit, across the languages your team writes in.
MergeGuide templates cover key ISO 27001:2022 Annex A controls relevant to software development:
Every MergeGuide detection rule is mapped to its ISO 27001:2022 Annex A control reference. When a violation is flagged, developers see the exact control number and requirement, not just a generic security warning.
Every PR Gate evaluation generates an immutable, timestamped artifact showing which Annex A controls were evaluated and whether code passed or failed. These artifacts feed directly into your ISMS evidence collection process.
ISO 27001 certification requires that controls operate continuously, not just at audit time. MergeGuide enforces Annex A requirements at IDE write time, AI generation time, git commit, and PR merge, throughout the development lifecycle.
Selected examples of what MergeGuide catches. These patterns run on every commit, across the languages your team writes in.
| Annex A Control | What MergeGuide Detects | Severity |
|---|---|---|
| A.8.24: Cryptography | Hardcoded cryptographic keys or use of deprecated algorithms (MD5, SHA-1) | Critical |
| A.8.24: Cryptography | Data at rest stored without encryption in database schemas and file writes | High |
| A.8.26: App security | SQL injection patterns: unparameterized queries accepting user input | Critical |
| A.8.26: App security | Missing input validation on externally-facing API endpoints | High |
| A.8.28: Secure coding | Command injection via unsanitized shell execution | Critical |
| A.8.20: Network security | TLS 1.0/1.1 usage or disabled certificate verification | High |
| A.8.3: Access restriction | Hardcoded credentials and secrets in source code | Critical |
