Codex Security, wherever your teams work
Use Codex Security across the tools your teams already use. Scan code in the cloud, review pull requests automatically, or run local security checks from your terminal with the open-source Codex Security CLI.
Codex Security plugin
Best for trying the workflow, reviewing a branch or investing one codebase.
Codex Security Cloud
Best for managed, ongoing security scans across connected GitHub repositories.
Codex Security CLI
Best for running security scans from your terminal and integrating them into local development or CI/CD workflows. Copy the following code, go to Codex and bash in your CLI: curl -fsSL https://openai.com/codex/security/scan.sh | bash
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.
Move from finding to fix
Codex Security + Daybreak Blue: Generate focused patches, run relevant tests, and produce reviewable changes with evidence for engineering approval.
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.
Trusted by leading security organizations
“We’re excited about the potential of OpenAI’s cyber capabilities to bring stronger reasoning and more agentic execution into security workflows. It’s a big step forward for teams to be able to leverage frontier models not only to accelerate velocity, but also to improve their security posture.”
