Intruder Likes & Dislikes

What stands out most about Intruder is the platform's ability to deliver clear, high-quality vulnerability intelligence while suppressing noise. The automated scans, combined with meaningful prioritization, allow our team to focus quickly on the most critical issues.

It helps us strengthen our security posture.

It does what we need it to do for us Requires very little interaction/maintenance on our part We haven't had any issues with it - it just works

There is nothing to dislike about the Intruder platform.

The licensing model makes it impossible for us to cover our entire organization with this product. The product does not catch all vulnerabilities, and does not check for outdated software, only issues with an attached CVE (which it does not catch all of them).

* The Help Center is buried under my account info but instead should be more prominent on the screen. It took me a while to find it. * More specific information on Ciphers and how they should be used for different situations * When requiring a software upgrade as the fix, sometimes we are unable to upgrade due to legacy concerns - suggestions on alternative methods to help protect would be nice (or a place to find such info)
