Public Audits
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.

Whitepaper
Custom security research and analysis of attack surface and technical mitigations enables our customers to go beyond the constant cycle of finding security issues in their software or infrastructure.
One such example is the Browser Whitepaper that X41 created for Google. X41 covers the differences in security design, implementation and user interface of the Google Chrome, Microsoft Edge and Internet Explorer browsers.
