Codex Security · The Daybreak model family
Codex Security pairs frontier reasoning with Daybreak Blue and Daybreak Red to surface the vulnerabilities that matter, prove they’re real, and ship the patch — before an attacker gets a vote.
Trusted by the teams the world trusts
The Daybreak family
Daybreak models plug into Codex Security or your own harness. Same frontier reasoning — pointed in opposite directions, on purpose.
Defense
The defender’s model. Trained for vulnerability discovery, exploit-path validation, remediation, threat modeling, and deep security investigation across real codebases.
Authorized offense
The adversary’s model — under your flag. Built for sanctioned red teaming, penetration testing, exploit validation, and tightly controlled security research.
Daybreak access is gated: qualified teams, additional safeguards, explicit authorization for offensive work.
Proof, at production scale
every one judged against the whole repository it lands in
from monorepos to the open-source projects they depend on
validated, patched, and merged — not just reported
See it work
A simulated Codex Security run against a demo service. Watch a finding get discovered, proven exploitable, and patched — the whole loop, no humans paged.
Ready when you are.
Deploy
In the IDE, in the cloud against your GitHub organization, or in your terminal and CI — same engine, three doors in.
The fastest way in. Point it at a branch or a single repository and watch the find–validate–fix loop run inside the tools your engineers already live in.
Best for: trying the workflow on one codebase.
Add the pluginManaged, always-on scanning across connected GitHub repositories. Every pull request reviewed for security before a human ever sees the diff.
Best for: continuous coverage of an entire org.
Connect GitHubOpen source and terminal-native. Run scans locally, wire them into pre-commit hooks, or gate CI/CD pipelines on validated findings.
Best for: local checks and pipeline automation.

Coverage
Sweep repositories and in-flight changes for the bugs that actually bite — with enough codebase context to rank signal over noise before anything ships.
Read the documentationCandidate findings get reproduced in isolation: reachability established, impact measured, evidence captured. Your triage queue becomes a short list of real risk.
Read the documentationTargeted patches, relevant tests, and a reviewable change with the evidence attached — engineering approves, the alert becomes a merged PR.
Read the documentationMap assets, entry points, trust boundaries, and sensitive data paths into a living threat model — so hardening happens before the incident, not after.
Read the documentationScoped penetration tests and realistic red-team exercises that show how weaknesses chain — under clear authorization and explicit rules of engagement.
Read the documentationMalware, binaries, firmware, controlled proofs of concept: when source code is incomplete or gone, Daybreak Red still reads what the attacker shipped.
Read the documentationIn production
“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.”
On-ramps
Start scanning tonight, apply for Daybreak’s gated capabilities, or bring frontier security to your own customers.
Connect a repository and let Codex Security find, validate, and help fix its first vulnerability — usually inside the hour.

03 — Partner with usEmbed frontier cyber capability into the tools and services defenders already rely on, with OpenAI as your model partner.
Questions
Anything you own: a repository, a branch, a single commit, or a local folder. Codex Security builds context around the whole codebase first, then concentrates on plausible, high-impact vulnerabilities rather than pattern-matched noise.
You get the affected code, a severity assessment, and the validation evidence — how it was reproduced and why it’s reachable. From there Codex can draft a targeted patch, run the relevant tests, and hand your team a reviewable change instead of a ticket.
Codex Security covers common defensive workflows out of the box. Daybreak access is for qualified teams doing advanced, authorized work — red teaming, exploit validation, malware analysis — that needs more permissive capability and comes with additional safeguards and controls.
Codex Security is the harness: it reads your repositories, runs scans, orchestrates validation sandboxes, and prepares patches. Daybreak Blue and Daybreak Red are the reasoning engines inside it. You can also call the Daybreak models directly from your own security tooling if you prefer to build the harness yourself.
Scans run against repositories you explicitly connect, validation executes in isolated environments, and business customer data is not used to train models by default. Enterprise agreements cover retention, access controls, and audit requirements — bring your security team to the first call.
Put frontier reasoning on your attack surface — and on your side of it.
