Secure public AI API endpoints
Protect public AI APIs with object authorization, bounded work, cost controls, constrained tools, safe output handling, and tested failure paths.
Secure Session Cookies
Configure host-scoped session cookies, choose SameSite deliberately, rotate identifiers, and test server-side expiry and revocation.
Audit Logs for Security-Sensitive Actions
Design scoped audit events that reconstruct sensitive actions, resist silent changes, protect private data, and survive collection failures.
Add a Security Diff Gate to Pull Requests
Build a pull-request security gate around immutable commits, explicit coverage, scanner failures, reviewable results, and one required decision.
Why Every Security Fix Needs a Retest
Retest a security fix against a fresh build, preserve equivalent coverage, check adjacent paths, and record confirmed or inconclusive outcomes.
Security Headers Every AI-Built App Needs
Build browser security headers from application behavior, stage CSP safely, and verify policies by route instead of chasing a score.
Build a Go / No-Go Security Launch Gate
Turn scoped security evidence into an accountable go, conditional, no-go, or not-evaluated decision with owners and rollback readiness.
Security Monitoring and Alerts Before Launch
Define security events, route actionable alerts to an owner, and test the complete monitoring path before an AI-built app launches.
How to reduce security scanner false positives
Reduce security scanner false positives with context, verification, narrow tuning, recorded suppressions, baselines, and fresh retests.
