ISO 27001 - Cryptographic Controls Policy Template
Cryptographic Controls Policy – Governing The Use of Encryption Within Your ISMS
Required under ISO/IEC 27001:2022 Annex A (Cryptography) - examined during certification and surveillance audits.
The Cryptographic Controls Policy is a critical ISMS policy required to demonstrate how an organisation governs the use of encryption and cryptographic techniques to protect information. It defines approved cryptographic methods, key management responsibilities, usage rules, and control ownership in line with risk treatment decisions.
Auditors assess this policy to verify that encryption is controlled and consistently implemented, not applied informally or left to technical teams without governance. Weak or generic cryptographic policies often lead to nonconformities where encryption is undocumented, unmanaged, or misaligned with risk assessments.
This template delivers a clear, structured, and audit-defensible Cryptographic Controls Policy, aligned with ISO/IEC 27001:2022 Annex A, helping organisations demonstrate cryptographic control and avoid audit findings.
Why This Document Matters?
- Defines approved cryptographic controls to protect sensitive information.
- Establishes clear rules for the use of encryption and cryptographic techniques.
- Assigns responsibility for cryptographic key management and controls ownership.
- Confirms cryptographic controls are selected based on risk treatment decisions.
- Provides documented evidence of approved and reviewed cryptographic practices.
What's Included in This Template?
- ISO/IEC 27001:2022–aligned cryptographic policy structure.
- Approved cryptographic principles and control objectives.
- Encryption usage and applicability guidelines.
- Cryptographic key management roles and responsibilities.
- Defined ownership for cryptographic controls and approvals.
- Risk-based selection of cryptographic controls.
Common Audit Issues This Helps You Avoid
- Vague or generic cryptography policy statements.
- Missing approval or ownership of cryptographic controls.
- Undefined encryption standards or usage rules.
- Cryptographic controls not aligned with risk treatment decisions.
- Weak or undocumented key management practices.
- Annex A Non-conformities related to cryptographic controls.
Who Should Use This Template
- Organisations implementing cryptographic controls within an ISO/IEC 27001 ISMS.
- Companies preparing for certification or surveillance audits with encryption in scope.
- Businesses formalising or updating cryptography and key management practices.
- Consultants supporting multiple ISO/IEC 27001 clients with cryptographic governance.
- Teams transitioning cryptographic controls to ISO/IEC 27001:2022 requirements.

Compliance Note
The Cryptographic Controls Policy is one component of a complete ISO/IEC 27001 ISMS. Certification also requires cryptographic standards, key management procedures, risk assessments, and implemented controls. All cryptography-related documentation must work together to demonstrate effective information protection during certification and surveillance audits.
