Policy-as-Code

Jan 1, 0001

Definition

Policy-as-Code is the practice of defining and managing security and compliance policies through code, enabling automated enforcement and validation across infrastructure and applications. This approach allows for version control, testing, and integration into CI/CD pipelines, ensuring consistent policy application and reducing human error. By treating policies as code, organizations can achieve greater agility and reliability in maintaining compliance and security standards.
