Common questions

What is Simuzo?

Simuzo is a hosting security and resource management plugin that integrates with popular control panels. It provides per-user filesystem isolation (SimuzoFS), cGroup resource limits, MySQL Governor, SecureLinks, audit logging, and a rootless Container Manager for end users.

Which control panels are supported?

Simuzo integrates with Webuzo, cPanel, Plesk, DirectAdmin, and InterWorx. Additional panel support continues to expand—see the Panels page for the current list.

How much does Simuzo cost?

If you already have an active Softaculous license on the server, Simuzo is included at no extra charge. Without Softaculous, licensing is $5 per server per month.

Does Simuzo replace my control panel?

No. Simuzo installs alongside your existing panel and adds isolation, limits, monitoring, and container tools. Your panel remains the primary interface for accounts, domains, and email.
