An Imunify360 license lets you run Imunify360, a security suite for Linux web hosting servers, on your own VPS or dedicated server. It combines a web application firewall, malware scanning and clean-up, intrusion detection and a network firewall that work together to block attacks on the sites you host. Tremhost supplies Imunify360 licences at $5 a month or $190 once off for a lifetime licence.
What Imunify360 is
Imunify360 is developed by CloudLinux, the company behind the CloudLinux operating system. It is built for servers that host many websites, typically with a control panel such as cPanel and WHM, Plesk or DirectAdmin. Instead of a single antivirus or firewall, it combines several layers that share information with each other, managed from one dashboard inside your control panel.
The main layers of protection
Web application firewall
The WAF inspects HTTP requests before they reach your sites and blocks common attack patterns, such as SQL injection, cross-site scripting and attempts to exploit known flaws in popular applications like WordPress.
Malware scanning and clean-up
Imunify360 scans files in hosting accounts as they are uploaded or changed and on a schedule. When it finds infected files it can clean or quarantine them, which saves you restoring a whole site from backup.
Proactive defence for PHP
Many website compromises run through malicious PHP scripts. Imunify360 analyses PHP execution in real time and can stop dangerous scripts from running, including ones that have not been seen before.
Network firewall and brute-force protection
The firewall uses IP reputation data and rate limits to block repeated failed logins against SSH, FTP, email and control panels, as well as known malicious addresses.
Shared threat intelligence
Imunify360 servers report attacks centrally. When one server detects a new attack source, others running Imunify360 can block it too, which helps against distributed brute-force campaigns.
Why it matters on a shared or reseller server
On a server with many accounts, one outdated plugin can let an attacker in. Without isolation and scanning, that one site can be used to send spam, host phishing pages or attack its neighbours, and the server’s IP address can end up on blocklists that affect everyone’s email. Imunify360 reduces that risk by catching malware early and blocking the requests that lead to infection. It works well alongside CloudLinux, which isolates each account so one site cannot read another’s files.
No tool removes the need for basic hygiene. Keep applications and plugins updated, remove plugins and themes you no longer use, use strong passwords and two-factor authentication, and keep off-server backups.
Imunify360 license options at Tremhost
- Monthly: $5 a month.
- Lifetime: $190 once off.
- Bundles: cPanel licence bundles that add CloudLinux, Imunify360, JetBackup and LiteSpeed start at $12 a month for a VPS.
These are shared licences supplied by Tremhost that receive official vendor updates, so your server runs current Imunify360 versions and threat data. They are not licences issued directly to you by CloudLinux. Prices are in US dollars, payable by EcoCash, InnBucks, ZimSwitch, Omari, Visa, Mastercard or cryptocurrency, and support is by ticket or WhatsApp, Monday to Friday, 08:00 to 17:00 CAT.
When you already have Imunify360 without buying a licence
You do not need your own licence if Tremhost runs the server for you. Imunify360 is included on:
- Reseller hosting, from $7 a month, alongside LiteSpeed and CloudLinux.
- Managed cPanel VPS, from $80 a month, with cPanel and WHM, LiteSpeed, CloudLinux and backups.
A separate Imunify360 licence makes sense when you run your own unmanaged VPS or dedicated server with a control panel and want to secure it yourself.
Setting up Imunify360 on your server
- Order the licence for your server’s IP address.
- Install Imunify360 using the vendor’s installer for your control panel, then activate the licence as shown on the licence page.
- Open the Imunify360 section in WHM, Plesk or DirectAdmin and review the default settings.
- Decide what happens to detected malware: clean automatically, quarantine or alert only.
- Enable scheduled scans and check the incidents list after the first few days to whitelist any false positives, such as your own office IP address.
If you buy any Tremhost licence, the team will configure the server for you free of charge.
Imunify360 and website-edge protection
Imunify360 protects the server. A content delivery network with a firewall at the edge, such as Cloudflare, stops many attacks before they reach the server at all and absorbs traffic floods that a server-side tool cannot. Tremhost’s Armor Guard is Cloudflare Pro, configured and monitored by Tremhost, for $9 a month for one site. Many busy sites use both layers together.
Frequently asked questions
Does Imunify360 replace backups?
No. It reduces the chance of infection and can clean many infected files, but backups stored off the server are still your recovery plan if something goes wrong.
Will Imunify360 slow my server down?
Scanning and filtering use some CPU and memory. On a correctly sized server the impact is usually small; you can schedule full scans for quiet hours.
Can I use Imunify360 without cPanel?
Yes. It supports other panels, including Plesk and DirectAdmin, and can run on servers without a panel.
My site is already hacked. What should I do?
Use Armor SOS for free same-day triage, then put prevention in place once the site is clean.
