CloudLinux OS is a commercial Linux distribution specifically designed for shared hosting providers. It isolates each hosting account into its own lightweight virtualized environment (CageFS), prevents any single user from consuming excessive CPU, RAM, I/O or entry processes through the Lightweight Virtual Environment (LVE) technology, and provides HardenedPHP to keep older PHP versions secure with backported patches. Together, these features dramatically improve server stability and security.
CageFS is a virtualized per-user file system that isolates each hosting account from one another and from the server's core system files. When enabled, users cannot see other users' files, processes, or sensitive server configurations. Even if one account is compromised, the attacker is confined within that user's CageFS and cannot escalate privileges or access other accounts. CageFS is completely transparent to end users — they experience normal hosting without knowing they are isolated.
LVE (Lightweight Virtual Environment) Manager allows server administrators to set precise CPU, memory, I/O, entry process and number-of-process limits on a per-account basis. If a user exceeds their allocated resources, only their processes are throttled — other users on the server remain completely unaffected. This prevents the "noisy neighbor" problem common in shared hosting and ensures fair resource distribution across all accounts.
HardenedPHP is a CloudLinux technology that backports security patches to older, end-of-life PHP versions (5.x, 7.x) that many legacy websites still require. Instead of forcing customers to upgrade their code to newer PHP versions, HardenedPHP keeps their current PHP version secure against known vulnerabilities. This is critical for shared hosting providers who host thousands of sites running different PHP versions.
Yes, CloudLinux OS is compatible with both virtual private servers (VPS/VDS) and dedicated/physical servers. The license covers a single server installation regardless of the hardware type. CloudLinux also supports all major control panels including cPanel/WHM, DirectAdmin and Plesk. Installation is straightforward — you can convert an existing CentOS/AlmaLinux server to CloudLinux with a single command.
CloudLinux licenses are issued per server based on the server's primary IP address. After purchasing a license from BurtiNET, your IP is registered instantly and you can install or convert to CloudLinux immediately. The license is validated automatically during system boot and periodically throughout operation. If you change your server's IP, simply update the license through your BurtiNET panel.
CloudLinux OS is the world's most widely deployed commercial Linux distribution for multi-tenant web hosting servers. Trusted by over 4,000 hosting providers and powering more than 200,000 servers globally, CloudLinux transforms a standard Linux server into a secure, stable and fair-usage hosting platform. By isolating users, hardening PHP, and preventing resource abuse, CloudLinux ensures that a single problematic account never impacts the entire server.
CageFS creates a fully virtualized file system for each user on the server. Every hosting account sees only its own files and a safe subset of server utilities — it cannot access other users' home directories, view the process list, or read sensitive configuration files like /etc/passwd or /etc/shadow. This effectively eliminates symlink attacks, local privilege escalation, and information disclosure vulnerabilities that are common on traditional shared hosting servers.
The Lightweight Virtual Environment (LVE) technology is the backbone of CloudLinux's resource management. It allows administrators to assign granular CPU, physical memory, I/O throughput, IOPS, entry processes and number of processes limits to individual accounts. When a user exceeds their allocation, only their processes are throttled or queued — the rest of the server continues operating at full capacity. LVE integrates with all major control panels and provides real-time monitoring dashboards.
Many websites rely on older PHP versions that have reached official end-of-life and no longer receive security patches from PHP.net. HardenedPHP solves this critical problem by backporting security fixes to PHP versions as old as 5.1, covering hundreds of known CVEs. For shared hosting providers, this means customers can continue running their existing applications safely without being forced into potentially breaking PHP upgrades.
SecureLinks is a kernel-level protection that prevents symbolic link (symlink) attacks — one of the most dangerous and commonly exploited vulnerabilities on shared hosting servers. Traditional symlink protection relies on Apache or PHP configuration, which can often be bypassed. SecureLinks operates at the operating system kernel level, making it virtually impossible for attackers to use symlinks to read files belonging to other users or the server itself.
