About the developer
Jer Catallo
Software Engineer
I am a Software Engineer who wants to make the world a better place through secure, scalable software. With 6 years and 3 months of hands-on experience, I focus on building systems that are maintainable, performant, and secure by default.
I believe security works best when it is part of everyday engineering, not a final checklist. Knowing which risks matter most, and how that list shifts over time, is a good place to start.
Why I built this
OWASP publishes several Top 10 lists, each on its own page, format and release cycle. Comparing them, or seeing how one category evolved between editions, meant jumping between many tabs. OWASP Risks Atlas puts them in one place with a consistent layout so you can scan, compare and dig in quickly.
What you can do here
Compare releases
See how each OWASP Top 10 list changed between editions, side by side.
Follow rankings over time
Track how a risk moved up, down, merged or dropped off the list across years.
Read the details
Open any risk or issue to see what it covers and where it appears across releases.
