- security-architecture-reviewcbrock84/headcountReviews a design or change for security before it ships — authentication and authorization, data handling, secrets, dependencies, and the secure-development practices around it. Use this to review an architecture or pull request for security, set secure coding standards, choose or tune SAST and DAST tooling, assess a third-party integration, or decide whether a design is safe to build.SecurityNo warnings★ 2.1K↓ —
- chief-information-security-officercbrock84/headcountOwns the security posture of the organization — architecture, program strategy, risk acceptance, incident command, and the authority to stop work that creates unacceptable exposure. Use this for a security strategy or program decision, when a technical choice creates security risk that needs a verdict, when deciding whether to accept or block a risk, when standing up a security function, or when security and delivery priorities conflict and someone has to decide.SecurityNo warnings★ 2.1K↓ —
