Vector

Vector is an autonomous pentester. Point it at your web app and our AI agents safely attack it the way a real hacker would, then hand back every weakness they found, proof that each one is exploitable, and the exact fix. It's simple to use, with no security background needed. You get an attacker's view of your app for a small fraction of the price and time. Most software shipped today has holes the people who built it never see. Vector finds them before someone else does.
