As the Vibe Coding development model becomes increasingly popular, more non-developer groups are able to quickly build and launch their own products with the help of agents like Codex and Claude Code. However, behind the significant reduction in barriers, product security often becomes the most easily overlooked blind spot.

Recently, OpenAI officially open-sourced a previously internally named security review tool called Aardvark, now named Codex Security. The open-sourcing of this tool means that the previously closed security scanning capabilities within the Codex ecosystem are now becoming open, allowing various external agents to directly call it.

As a security assistant driven by advanced large models, Codex Security can deeply access code repositories, autonomously read code, identify vulnerabilities, verify risks, and provide specific solutions for fixes. In practical use, users can not only directly call it through Codex authorization login or OpenAI API Key, but also integrate third-party models via OpenRouter, such as choosing cost-effective models like DeepSeek for vulnerability reviews, thus meeting the different cost and preference needs of various developers.

Industry experts point out that although these tools can significantly enhance the security at the code level, network security is not a one-time solution. Facing complex challenges such as daily backend maintenance, CDN protection, and potential DDoS attacks, developers still need to maintain a regular habit of security reviews to effectively prevent losses caused by vulnerabilities or interface permission issues.
