What’s inside HardenedPHP and why it matters for server security
It’s been more than a year since we started our HardenedPHP project. The idea came out of discussions with multiple hosters who expressed their worry about running outdated versions of PHP. While their servers were secured with CageFS , they were still worried that hackers could have a field day with all the sites running PHP 4.4 or 5.1. Even thoug...

Ubuntu LTS 16.04 includes livepatch - now what?
Livepatch, a technology to apply patches to a running kernel, has been available for some time. Now Ubuntu LTS 16.04 became the first major Linux distribution to enable it in their kernel.

HardenedPHP - another day, another security fix

This is where HardenedPHP  comes in - it patches those holes so that your servers can remain secure. On Mar 31, 2016 new versions of PHP were released. With the...

KernelCare prevents from attacks fast - releases patches sometimes even before the native OS updates its kernel
You might say that KernelCare lags slightly behind the upstream distributions of patches. This, however, is normal, and regardless of the delay, most of the time you will be protected by KernelCare much faster than you would do the reboot yourself.
