A full security engineering field guide for developers, founders, and anyone building in public. Free to read. Built from real knowledge. Written for real people.

🌐 Read it live at secureyour.sh

Secure Your Ship is a comprehensive, plain-English security field guide built for developers, self-taught builders, bootcamp grads, indie hackers, founders, and anyone who has ever Googled "how do I secure my GitHub repo" and gotten a Stack Overflow thread that assumed they already knew what they didn't.

Nobody handed me a roadmap when I started. I found my way into tech from a kitchen — no CS degree, no connections, no one telling me where to start. After engineering courses, AI training, and graduating a cybersecurity program, I still felt like pieces were missing. The knowledge existed — scattered across bookmarks, Notion docs, Obsidian vaults, Slack threads, and textbooks. Nothing connected.

So I built the guide I needed and couldn't find. Then I put it on the internet. For free.

This is that guide.
