Grsecurity has existed for over 14 years now. During this time it has been the premier solution for hardening Linux against security exploits and served as a role model for many mainstream commercial applications elsewhere. All modern OSes took our lead and implemented to varying degrees a number of security defenses we pioneered; some have even been burned into silicon in newer processors. Over the past decade, these defenses (a small portion of those we've created and have yet to release) have single-handedly caused the greatest increase in security for users worldwide.
