# Replit adds black-box penetration testing for apps

By Steven Van · 2026-08-17

Scans probe a running Replit app like an outside attacker would, and Replit's Agent can apply a fix in one click.

Replit apps can now be scanned with black-box penetration tests, security checks that probe a running app the way an outside attacker would rather than by reading its code. When a scan turns something up, [Replit](<https://creatorstoolbox.com/tools/replit>)'s Agent can apply a fix in a single click.
