• Automate repetitive operational tasks to improve deployment speed and reliability.
• Implement pipeline security gates and automated checks.
• Embed security checks across the SDLC (SAST/DAST/SCA) and container image scanning.
• Manage secrets securely using Vault or AWS Secrets Manager.
• Implement policy-as-code and compliance-as-code to enforce guardrails.
