AI writes software faster than teams can secure it. Attackers use AI to exploit the gaps.
Your security needs not only to find vulnerabilities, but also to fix them automatically.
Security handled, 24/7.
0.security closes the loop:
We find vulnerabilities before your code ships & deliver the 1-click fix.
Cyber Intelligence
Tracks newly disclosed vulnerabilities and known exploits, and matches them against your codebases.
Auto-remediation
Creates fixes for vulnerabilities found in pull requests. Apply the fix with 1 click directly in the same PR.
Dependency Security
Uses software composition analysis (SCA) and 24/7 CVE monitoring to find & fix security issues in all your dependencies.
Codebase Pentest
AI agents find & fix previously unknown vulnerabilities (0-days) and known CVEs across your stack. Run tests hourly, daily, or on your own schedule.
Continuous Pentesting
AI agent swarms find attack paths like a real attacker & fix previously unknown vulnerabilities (0-days) and known CVEs across your website, live app, infrastructure etc.
Binary Pentest
Binary-native Cyber Reasoning System for reverse engineering and vulnerability discovery in compiled programs, with no access to source code.
The world’s best security should be accessible to everyone.
How it works
Indexes & understands your codebase
Builds a graph of your repo, dependencies and infrastructure and analyzes your coding conventions.
Swarms of AI security agents find & fix
Parallel agents investigate like a real AI-powered attacker to find, verify and prepare fixes for complex vulnerabilities.
- Kernel-level isolation✓
Verifies findings & filters out false alarms
Agents independently reproduce findings in isolated sandboxes and verify fixes. Only verified findings reach your team.
Learns your code and gets better over time
Context about your code, architecture and past findings carries into the next investigation.
Why not just prompt
Codex or Claude Code?
Your coding agent
| Your coding agent | 0security |
|---|---|
| You find less. | Optimized multi-model orchestration, hacking tools and codebase context uncover more vulnerabilities. |
| You have to start and manage every check. | Security tests run on schedule and with code changes. Dependency checks run automatically and are monitored 24/7. |
| You end up with more work. | We verify findings, deliver only tested fixes and learn from every review. |
| You don’t know what matters most. | Real exploits prove vulnerabilities and show their business impact. |
| You can’t scale safely and put your machine at risk. | Agent swarms investigate in parallel with dedicated sandboxes and compute. |
For wherever your team already builds.
No new dashboard to babysit.
Fix with your coding agent
Give Codex, Claude Code or Cursor the finding context and a prompt to investigate, fix and verify it.
