    Hi @Lillike You will not be able to get KernelCare in any form on the VPS Container you're running. The symlink protection patch would need to be applied to the hostnode it cannot be applied at the container level. This is detailed here in the comments: How to Harden Your cPanel System's Kernel - cPanel Knowledge Base - cPanel Documentation [root@]# uname -a Linux ~server.com 2.6.32-696.299.10.3.cp6.x86_64 #1 SMP Thu Sep 28 21:04:26 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux 2. Is it compatible for VPS virtuozzo or only VPS KVM / Server? Waiting for your info? How to Harden Your cPanel System's Kernel - cPanel Knowledge Base - cPanel Documentation) 2. It is compatible only with virtual machines or server. It is not compatible with containers.
