CloudLinux OS

CloudLinux Features

CloudLinux is designed from the ground up to secure and control individual tenants in shared hosting environments. CloudLinux stops intruders, prevents various attacks and increases server performance. Linux was never meant to be used by a large number of unvetted users. It is too easy for a hacker to obtain an account by signing up or by abusing some script, gain inside access to the server and begin poking around. CloudLinux stops that.

While a normal Linux server may go offline due to sudden spikes caused by a single tenant, CloudLinux stays stable by isolating the impact to the offending tenant. It creates a Lightweight Virtualized Environment (LVE) with CageFS for each tenant and "cages" them, separating from issues caused by others. Any error or failure specific to a single tenant will only affect that tenant and others will not experience any of it. All tenants on the server are isolated from each other so if one goes down everyone else is still stable and safe.

CageFS Virtualized File System

CageFS is a virtualized, per-user file system that encapsulates each user, isolates them in "cages" to increase security. It prevents them from seeing each other and stops most information disclosure attacks and privilege escalation attacks.

KernelCare Automatic Security Patches

KernelCare makes sure our servers will always be amongst the firsts to be patched in the event of a zero-day vulnerability being discovered. KernelCare automatically installs kernel updates without any reboot required.

Lightweight Virtual Environment (LVE)

The Lightweight Virtualized Environment (LVE) shields the server from performance spikes, slowdowns and downtimes by isolating each tenant into their own environment. This makes it rock-solid stable, even in the most stressful situations.

Prevent Attacks Using SecureLinks

SecureLinks is a kernel-level technology that prevents intruders from creating symlinks and hardlinks to files that they don’t own and prevents all known symbolic link attacks, which further enhances server security.

Lighting Fast PHP Using Mod_lsapi

Mod_lsapi is the fastest and most reliable way to serve PHP pages, keeping servers lightning-fast. It is a drop-in replacement for SuPHP, FCGID, RUID2, and ITK. It has a low memory footprint and doesn't suffer from stability issues.

PHP Selector & MySQL Governor

The PHP Selector allows end users to select the specific version of PHP they need. MySQL Governor monitors MySQL usage, prevents overloads and improves overall stability and keeps the server high-performing all the time.
