Kind Words From Our Clients
The technology behind Grsecurity/PaX is known the world over by top tier practitioners as the most effective stack of hardening measures for Linux. What most of us don't learn until we start to work with Grsecurity commercially is that the support deliverable blows the competition away by the same margin.
Boris Lukashev Semper Victus, Principal Architect
For security-oriented webhosters like us, grsecurity is essential. It raises the bar for common exploitation techniques significantly and prevents most kernel-related exploits, saving us a lot of time and stress.
Thibault Koechlin NBS System, Chief Security Officer
When building systems that hold sensitive customer data, no other platform is as trusted by professional security engineers, like those at Immunity, than grsecurity. We have 15 years of experience breaking systems and grsecurity has 15 years of experience protecting them from people like us.
Dave Aitel Immunity Inc., CEO
Draper strongly recommends grsecurity to all of our Department of Defense (DoD) customers so they have the latest and state-of-the-art in vulnerability prevention and exploit defense.
Curtis Walker Draper, Chief Scientist
We have been using grsecurity as part of our container based application streaming delivery solution for the enterprise. Grsecurity has provided us the differentiation we needed over the legacy solutions, especially in the areas of exploitation resilience and trusted execution. I would highly recommend grsecurity to anybody who wants to build a solution over a secure and robust foundation. It is a must-have.
