About

Codex Security is an AI-powered application security agent developed by OpenAI to help teams detect and fix vulnerabilities in software systems. The tool analyzes code repositories to understand the structure, architecture, and potential risk areas within a project. Using this context, it identifies complex security issues that traditional scanning tools might overlook. Codex Security prioritizes vulnerabilities based on their real-world impact, helping security teams focus on the most critical threats. The system also validates findings through sandboxed testing environments to reduce false positives and improve accuracy. Once vulnerabilities are confirmed, it proposes patches and remediation steps that align with the system’s existing behavior. By combining AI reasoning with automated validation, Codex Security helps development teams ship more secure code faster.

About

Your AI agent ships thousands of lines a day, and most of them never get a real review. CybeDefend works inside the agent while it codes. One command installs VibeDefend on Claude Code, Cursor, Windsurf, GitHub Copilot, Codex and other agents. From then on the agent writes with your business rules in its context, mined automatically from your repo (tenant scoping, soft delete, audit on write), next to your security rules (OWASP, SOC 2, GDPR, ISO 27001). It scans each diff while the file is still open, and a guard refuses commands like rm -rf, sudo or a read of your secrets before they run. Behind it sits a full AppSec platform with SAST, SCA, secrets, IaC, CI/CD and container scanning, plus AutoFix. The free plan needs no card and includes 10 static scans and 50 AI credits. Paid plans start at $19 a month. npx -y @cybedefend/vibedefend@latest install
