Find tomorrow’s vulnerabilities today!
We help you handle vulnerabilities in products you use or develop. Beyond identifying individual vulnerabilities, X41 shows you how to improve your products and infrastructure in design and make it resilient even against future threats.
We take care of vendor contacts and work out the technical details with security researchers and developers to do vulnerability reporting.
Our process for finding vulnerabilities and getting them fixed is based on years of experience in uncovering vulnerabilities.
Some of our customers love transparency and publish the results of security audits together with X41. This helps them to show that they actually care about security and aim to improve the robustness of their software and lets the user base of these applications verify that security is not just an empty claim.
