Why a security suite
A hosting server faces the same attacks every day: password guessing on logins, exploit attempts against old plugins, uploaded web shells, and malware injected into PHP files. A suite combines the defences in one place, with one dashboard and one set of alerts, instead of separate tools for the firewall, scanner and WAF.
Feature overview
| Area | Imunify360 | cPGuard |
|---|---|---|
| Malware scanning | Real-time and scheduled scanning, with automatic clean-up | Real-time and scheduled scanning, with automatic clean-up |
| Web application firewall | Yes, with rules maintained by the vendor | Yes, with its own rule set |
| Brute-force and login protection | Yes, with IP reputation data | Yes |
| Proactive protection | Proactive Defense can block malicious PHP while it runs | Check the vendor’s current feature list |
| Patch management | Kernel live patching (KernelCare) and CMS vulnerability patching as add-ons | Not a main feature |
| Control panels | cPanel, Plesk, DirectAdmin and standalone | cPanel, DirectAdmin, Plesk and others |
| Free option | ImunifyAV (scanner only) | Check the vendor |
Both products change often. Check each vendor’s current feature list and pricing before you decide.
When Imunify360 fits better
- Shared or reseller servers with many accounts, where proactive PHP protection and automatic clean-up save support time.
- Servers already running CloudLinux, where Imunify360 works together with CageFS and LVE limits.
- Teams that want vulnerability patching for WordPress plugins and live kernel patching from the same vendor.
When cPGuard fits better
- Smaller servers where licence cost is a large part of the budget.
- Administrators who want a lighter tool and are comfortable tuning rules themselves.
- Servers on panels or setups where you prefer cPGuard’s integration.
How to compare them on your own server
- Take a backup or snapshot of the server.
- Install one product with a trial licence, and leave it in a monitoring or report-only mode where possible.
- Run a full scan, and review what it finds and what it would change.
- Watch CPU, memory and disk use during scans, and the false positives reported by your users.
- Remove it cleanly, then repeat with the other product, before you choose.
Do not run both at once:
Two security suites on one server conflict over the firewall, the WAF rules and file scanning. Uninstall one completely before installing the other.
What to check before you buy
- ✓ Licence model: per server, per number of accounts, or per domain.
- ✓ Support for your control panel version and operating system.
- ✓ How malware clean-up works, and whether you can restore a cleaned file.
- ✓ How the firewall works with your existing one, such as CSF.
- ✓ Resource use during full scans on a server like yours.
What happens when a site is infected
Both suites can find an infected file and either clean it, quarantine it, or report it. Before you turn on automatic clean-up, decide how you want to handle false positives: a cleaned file that was actually needed can break a site. Start with reports only, review the first results, and keep backups, so any file can be restored. After an infection, always find the cause, usually an outdated plugin or a stolen password, or the site will be infected again.
Security basics that matter whichever you choose
- Keep the operating system, cPanel and PHP updated.
- Use strong passwords and two-factor authentication for WHM and cPanel.
- Keep off-server backups and test restores.
- Harden SSH and the firewall. See our cPanel security tips and CSF firewall guide.

Frequently asked questions
Is Imunify360 better than cPGuard?
Neither is best for everyone. Imunify360 offers a broader platform; cPGuard is lighter and often cheaper on small servers. Test both on your server.
Can I run Imunify360 and cPGuard together?
No. They conflict. Use one security suite per server.
Is there a free version of Imunify360?
ImunifyAV is free and scans for malware. Clean-up and the full firewall and WAF need paid editions.
Do I still need CSF with a security suite?
Usually not. Imunify360 and cPGuard include firewall features, and running two firewall managers causes conflicts.
Can UnderHost install a security suite for me?
Yes. Our server management team can install, configure and monitor a security suite on your VPS or dedicated server.
