The hosting-optimized Linux OS with per-account resource isolation. Eliminate noisy neighbors, improve server density, and boost PHP performance with LVE technology.
CloudLinux OS is purpose-built for hosting providers and resellers. Its Lightweight Virtual Environment (LVE) technology isolates each account, preventing resource abuse. CageFS provides filesystem isolation, and PHP Selector allows per-user PHP version control.
Lightweight Virtual Environment limits CPU, RAM, I/O, and entry processes per account. No single user can bring down your entire VPS — guaranteed stability.
Each user is confined to their own virtualized filesystem. Users cannot see other accounts, system files, or sensitive configurations. Prevents escalation attacks.
Let each hosting account choose their PHP version (5.6 through 8.3) with per-user php.ini customization. No server-wide PHP changes needed.
Automatically throttles abusive MySQL queries before they impact other accounts. Prevents database overload and maintains server-wide responsiveness.
Prevents symlink attacks that target shared hosting. HardenedPHP patches known vulnerabilities in unsupported PHP versions.
Deep integration with cPanel/WHM including LVE Manager plugin. Set and monitor resource limits directly from WHM interface.
