A few months ago it was Alibaba releasing [Open Code Review](https://github.com/alibaba/open-code-review?ref=cephalosec.com). If you prefer the DIY way, [Cloudflare also shared their own blueprint](https://blog.cloudflare.com/build-your-own-vulnerability-harness/?ref=cephalosec.com#two-objections-up-front) for what they call the Vulnerability Discovery Harness and Vulnerability Validation System.\n\nI can see this approach growing if we can keep the token costs manageable, it will for sure cannibalize the bug bounty and maybe parts of penetration testing budgets.", "url": "https://wpnews.pro/news/cybersecurity-harnesses-everywhere", "canonical_source": "https://cephalosec.com/blog/cybersecurity-harnesses-everywhere/", "published_at": "2026-07-28 21:56:03+00:00", "updated_at": "2026-07-28 21:58:06.871091+00:00", "lang": "en", "topics": ["ai-tools", "ai-products", "ai-safety", "developer-tools"], "entities": ["OpenAI", "Codex Security", "Microsoft", "Project Perception", "Strix", "Alibaba", "Open Code Review", "Cloudflare"], "alternates": {"html": "https://wpnews.pro/news/cybersecurity-harnesses-everywhere", "markdown": "https://wpnews.pro/news/cybersecurity-harnesses-everywhere.md", "text": "https://wpnews.pro/news/cybersecurity-harnesses-everywhere.txt", "jsonld": "https://wpnews.pro/news/cybersecurity-harnesses-everywhere.jsonld"}}
