OWASP Top 10

A widely used list of the ten most critical web application security risks, maintained by the OWASP foundation.

The OWASP Top 10 is a consensus ranking of the web security risks that cause the most real-world damage, from broken access control and injection to misconfiguration. It's updated every few years and is the closest thing the industry has to a shared baseline checklist.

For a solo founder it's useful precisely because you can't read every security paper. The list tells you where attacks actually concentrate, so you spend your limited time on the bugs that matter instead of obscure edge cases. Most breaches of small products trace back to one of these ten categories.

If you want it in founder terms rather than security jargon, the OWASP Top 10, explained for founders breaks each category down with concrete examples. Kalit Pentest checks your app against these categories before you launch.
