TRUSTED BY HOSTING PROVIDERS WORLDWIDE
Works with cPanel, Plesk, and DirectAdmin on AlmaLinux, Ubuntu, and CentOS.
Your biggest challenges, solved by the CloudLinux product family
Hosting providers’ hardest problems rarely have a single cause, so CloudLinux products address them as a connected ecosystem. Start with what you need today and extend as you grow.
The CloudLinux foundation
Stability, performance, and longevity for every server you run.
CHALLENGE 01
One noisy account slowing down the whole server
Contained
Resource spikes stay isolated per account. Neighbors stay unaffected.
SOLVED BY
Lightweight Virtualized Environment (LVE) caps CPU, memory, I/O, and more, while CageFS isolates each account’s filesystem. Isolates extend that isolation down to the individual site, and PHP Selector lets each site run the exact PHP version it needs. One account hitting its limits affects only that account.
Consistent performance for every customer, even during traffic spikes.
CHALLENGE 02
Slow sites generating complaints and churn

SOLVED BY
Automated caching, image optimization, and SmartAdvice recommendations speed up WordPress sites with no manual tuning. MAX Cache serves cached pages straight from Apache or Nginx without running PHP at all, for roughly 3x the requests per second and 75 to 80% lower CPU. Both are included with your CloudLinux subscription.
Faster sites, lower server load, and higher density across your customer base.
CHALLENGE 03
End-of-life software as a growing attack surface
Patched
Security fixes for the software you still run, without a forced migration.
SOLVED BY
HardenedPHP + ELS
HardenedPHP backports security fixes to end-of-life PHP versions, included with CloudLinux, so legacy sites stay patched on the exact version they need. Endless Lifecycle Support extends that coverage to the rest of your stack: end-of-life operating systems, databases like MariaDB and MySQL, Apache, and system libraries, delivered as drop-in updates through the package manager you already use.
Stay secure and compliant on the stack you run today, and upgrade on your own schedule.
CHALLENGE 04
Kernel patches requiring scheduled downtime
Zero reboots
Live kernel patching applied without maintenance windows or downtime.
SOLVED BY
KernelCare applies kernel security updates live, with no reboots and no maintenance windows, so there’s no exposure gap between a patch release and your next scheduled downtime. It runs as a standalone product on your servers, and is also included with an Imunify360 subscription.
Servers stay patched and available, with no customer-facing disruption during security updates.
The Imunify security layer
Automated protection that stops attacks and cuts the tickets they generate.
CHALLENGE 05
Hacked sites flooding your support queue
-80%
reduction in “hacked site” tickets after standardizing on Imunify360
HostArmada
SOLVED BY
Proactive, multi-layered protection blocks attacks in real time, removes infections automatically, and forces the resets of compromised passwords to break the reinfection cycle.
Fewer “my site is hacked” tickets and far less reactive firefighting.
CHALLENGE 06
Vulnerable WordPress plugins and themes
53%
of providers cite outdated or vulnerable software as their top security challenge
2026 Hosting Trends Report
SOLVED BY
A dedicated WordPress layer on the Imunify360 web application firewall virtually patches vulnerable plugins and themes, blocking known exploits so customer sites are shielded before they can update. It already protects more than 860,000 WordPress sites, and it’s included with Imunify360 at no extra cost.
The number-one hosting security challenge handled, without touching a line of customer code.
CHALLENGE 07
Outbound spam getting your mail servers blacklisted
Protected
Outbound spam blocked before it reaches the recipient and damages your sender reputation
SOLVED BY
Imunify Email filters spam in both directions right on the server. It stops the outbound spam that lands IPs on blocklists, routes inbound spam and phishing to Junk, and monitors your server IPs against major blacklists for early warning. For outbreak-proof delivery, Imunify Email Gateway routes outbound mail through a managed cloud IP pool, so a single compromised account never blacklists your servers.
Fewer email deliverability tickets and a protected sender reputation across your mail servers.
CHALLENGE 08
VPS customers expecting shared-hosting reliability
One unified stack
Shared and VPS on the same tools, training, and support workflow
Hosting Ireland & LetsHost
SOLVED BY
The CloudLinux VPS Bundle ships CloudLinux and Imunify360 together for VPS and dedicated servers at up to 55% off standard licensing. The same stack your shared hosting already runs.
One vendor. One support channel. One licensing structure for both shared and VPS.
A NEW KIND OF OPPORTUNITY… AND RISK
Your customers are about to run AI agents on your servers
AI agents like OpenClaw don't just answer questions. They read files, run commands, and make network calls on their own. That's a new revenue tier for you, and a new kind of risk: traditional security is built to keep attackers out, not to keep an authorized agent inside the lines. A prompt-injected or compromised agent can read private keys and send them anywhere.
Imunify for AI Agents monitors and controls what every agent does, enforced at the operating-system level so even a fully compromised agent can't bypass it. Dangerous actions are blocked automatically, and anything that needs judgment is held for your approval.
Offer AI-enabled hosting as a premium capability, without taking on unmonitored risk.
From the makers of Imunify360, the engine protecting 65M+ domains. Imunify for AI Agents is in its Priority Access Program, free for hosting providers joining as design partners.
Turn your infrastructure into a revenue line, not just a cost
CloudLinux products are built with upsell mechanics and billing integrations that let you grow average revenue per user without adding headcount.
Start with the foundation
CloudLinux and Imunify360 give every customer on your server a faster, more secure environment as a baseline. Fewer tickets. Better retention.
Upsell performance features for WordPress
AccelerateWP Premium features integrate directly with WHMCS. SmartAdvice identifies which customers are ready to upgrade. Revenue per account grows automatically.
Differentiate your premium plans
Bundle the full stack, from performance to security to longevity, into higher tiers that command a premium instead of competing on price. The value your customers can see is the value they will pay for.
Already selling VPS or dedicated? Enhance your plans with value-adds and grow your margins
The CloudLinux VPS Bundle lets you add Imunify360 and CloudLinux to your VPS and dedicated plans at partner pricing, with up to 55% off standard licensing. HostArmada, Hosting Ireland, LetsHost, HostPress, Esmero, and more than 100 partners already made this their standard managed VPS offering.
Hosting providers are already seeing the results.

Hands down, the best decision that a web hosting company can make is to incorporate the CloudLinux OS and Imunify360 on their VPS services.
Less problems for the customer means happier customers. Which means happier employees, and a more profitable business. So everyone’s a winner.
If I were starting a new hosting company offering hosting for WordPress, I’d always start with CloudLinux and Imunify360. It’s a Swiss knife solution. All the features you need, in one bundle.
Questions hosting providers ask first
CloudLinux handles stability and isolation, but stability alone doesn't grow revenue or reduce every support drain. Providers running the full stack (CloudLinux, Imunify360, AccelerateWP, and KernelCare) report fewer security tickets, faster sites, and new upsell revenue from the same servers. Everything runs in the environment you already have.
No. Imunify360 runs on most major Linux distributions, including CentOS, AlmaLinux, and Ubuntu, without CloudLinux. Running both together unlocks the full stability and performance stack: LVE resource isolation, CageFS, HardenedPHP, and AccelerateWP. Most providers who start with one end up running both.
Yes. Both products support file-based and command-line driven configuration, built for automation with tools like Ansible and Puppet. Centralized monitoring gives you fleet-wide visibility from a single dashboard once deployed.
No. It's the same products, packaged together at discounted licensing.
AccelerateWP Premium integrates with WHMCS directly. SmartAdvice surfaces upsell opportunities inside the hosting panel, so the upgrade path is smooth for your customers.
Endless Lifecycle Support keeps end-of-life software patched (operating systems, databases, and more) without a forced migration, delivered as drop-in package-manager updates. If you run legacy OS versions or databases, ELS keeps them secure while you plan the upgrade on your own schedule.
