Isolate Tenants. Protect the Server.
Keep one runaway account from dragging down the whole server. CloudLinux isolates tenants, caps resources per account, and hardens the kernel.
Each hosting account runs in a sealed filesystem — no account can read, write, or traverse another's files.
CPU, RAM, and I/O capped per account at the kernel level. One runaway site cannot starve the rest of the server.
Kernel-level resource caps prevent overcommit, so you can safely host twice as many accounts on the same hardware.
One flat-rate license covers your entire server with kernel-level protection.
CloudLinux Features
Per-Account Resource Limits
LVE technology caps CPU, RAM, and I/O for every account on the server. When one site gets a traffic spike, the rest stay unaffected.
CageFS Filesystem Isolation
Each account runs inside its own virtual filesystem. Tenants cannot see each other’s files, which blocks most privilege-escalation exploits and stops cross-account data leaks.
Run Up to 2x More Accounts on the Same Server
CloudLinux isolates each account’s CPU, RAM, and I/O, so one account’s traffic spike does not slow the rest. That gives you room to host up to 2x more accounts on the same hardware.
Hardened Kernel
The CloudLinux kernel blocks symlink attacks and trace exploits, restricts /proc visibility, and delivers security patches faster than upstream CentOS or RHEL.
Resource Usage Dashboard
The cPanel & WHM integration gives you and your clients per-account visibility into CPU, RAM, I/O, and connection usage with adjustable limits.
PHP Selector
Each account picks its own PHP version, from 7.4 through 8.3, and controls its own extensions, memory limits, and configuration directives.
MySQL Governor
Throttle database queries by account so a single runaway query cannot starve the MySQL server. Set per-user CPU and I/O limits on database operations.
CloudLinux Pricing
Add CloudLinux to any Togglebox server. One license covers the entire server. Every account gets LVE resource limits, CageFS isolation, and kernel-level protection.
Common Questions
Which add-ons are best for Cloud VPS?
Most Cloud VPS buyers start with performance (LiteSpeed), control panel (cPanel/WHM), and security (Imunify360 or managed firewall) based on workload needs.
Do these add-ons work on App Hosting too?
Many App Hosting features are built in, so not every VPS add-on is required. Use App Hosting for managed platform defaults.
How is add-on billing handled?
Add-ons are billed at the rate and cadence shown on each product page. Usage-based add-ons (such as per-seat licenses) list the exact unit price. You can review current charges in the billing dashboard.
