It’s Free

We want to make the web safer, so we are letting everyone benefit from PT BlackBox Scanner for free. It’s based on the same innovative technologies as our highly-regarded PT Application Firewall and PT Application Inspector, the result of years of research and practical pentesting. Now we’re sharing that experience with the world!

It’s Simple

We’ve worked hard to make PT BlackBox Scanner quick and easy to use. Enter the website address below and click SCAN. There’s a simple registration process and then the free website security scan begins, even if your website is behind NAT. You’ll soon have a set of clear and easy-to-understand results.

It’s Accurate

We’ve optimized PT BlackBox Scanner for speed and detection rates. It’s built on our proven AppSec technologies that have already uncovered many confirmed vulnerabilities in websites of all kinds, including web services and CMS, allowing the site owners to improve their protection. Try it and see for yourself.

It’s Universal

Our free vulnerability scanner is for everyone, whether they own one website or 100. It’s also the perfect tool for professionals offering penetration testing services.

It’s Safe

We’ve taken steps to prevent illegal use. Users download a lightweight, open-source program that tunnels all requests through the user’s machine, even though our servers carry the load. Alternatively, they place a confirmation file in the root directory to prove they own the website.

It’s from Positive Technologies
