Re: [gentoo-hardened] Hardening a Kernel post hardened-sources

[Guillaume Ceccarelli]

Hi all,

I’ve been a grsecurity customer for a little over two years now, and my use of it is as a small business, on Gentoo server installations. While I can’t disclose the amount of money I’m paying publicly because every deal is customized, I would encourage you to get in touch using the contact form on grsecurity.net and ask for a quote if you haven’t already.

You might just end up with an arrangement you can afford, and grsec is still certainly worth having today. Not only for the feature set, but also for the constant looking over the mainline Linux kernel code, including fixing and backporting more fixes than the regular kernel stable releases, and for knowledge / emails giving context to important kernel vulnerabilities when they occur.


Best,

– Guillaume Ceccarelli
