Built for the full security workflow
Find vulnerabilities in code
Codex Security + Daybreak Blue: Scan repositories and code changes for likely vulnerabilities, using codebase context to surface high-signal findings before they reach production.
Validate what matters
Codex Security + Daybreak Blue: Reproduce candidate findings, establish reachability and impact, and capture evidence so teams can focus on vulnerabilities that present real risk.
Anticipate how systems may be attacked
Daybreak Blue: Map assets, entry points, trust boundaries, sensitive data paths, and abuse cases to help teams prioritize security work before incidents occur.
Test systems like an adversary
Daybreak Red: Conduct scoped penetration tests and realistic red-team exercises to validate defenses and demonstrate how vulnerabilities could be chained, under clear authorization and rules of engagement.
Investigate complex security targets
Daybreak Red: Analyze malware, binaries, firmware, and controlled proofs of concept to investigate bounded security hypotheses when source code is incomplete or unavailable.
