I Built a Product Security Knowledge Base — A Public Reference System for Engineers, Architects, and Security Leaders

There is no shortage of security content on the internet. There are blog posts, vendor docs, conference talks, GitHub repositories, whitepapers, checklists, cheat sheets, diagrams, bookmarks, saved screenshots, half-finished notes, and “I should come back to this later” tabs that quietly die in the browser. The problem is not that information is missing. The problem is that useful Product Security knowledge is often fragmented, uneven, and hard to navigate when you actually need it. And that becomes a serious issue the moment you work across modern engineering environments. Because Product Security is not one narrow box. It lives at the intersection of Application Security, API Security, DevSecOps, cloud security, Kubernetes, software supply chain security, secure architecture, identity, platform access, abuse prevention, governance, and leadership. In real life, those areas do not stay neatly separated. They overlap constantly. One hour you are thinking about secrets exposure in CI/CD
