What is ZeroFlaw?
ZeroFlaw is a security scanner that automatically checks your source code and domains for vulnerabilities. You get a clear overview with letter grades (A–F) so you can immediately see where action is needed.
You don't need security expertise – ZeroFlaw explains every issue it finds in plain language and shows you exactly where it is in the code.

Tip
Start with a code scan – that's where you'll get the most detailed results.
Reading results
After the scan completes you'll see a grade from A to F and a list of all vulnerabilities found. Each finding has:
- A severity (Critical, High, Medium, Low, Info)
- A description explaining the issue
- The exact location in the code (file and line)
