Fewer support tickets. More revenue per server. A hosting stack that sells itself.

Compatibility
The CloudLinux foundation
Stability, performance, and longevity for every server you run.
One noisy account slowing down the whole server
Resource spikes stay isolated per account. Neighbors stay unaffected.
CloudLinux
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.
Slow sites generating complaints and churn

AccelerateWP + MAx Cache
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.
End-of-life software as a growing attack surface
Security fixes for the software you still run, without a forced migration.
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.
Kernel patches requiring scheduled downtime
Zero reboots to the live kernel patching applied without maintenance windows or downtime
KernelCare
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.
Hacked sites flooding your support queue
~80% reduction in “hacked site” tickets after standardizing on Imunify360

Imunify360
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.
Vulnerable WordPress plugins and themes
53% of providers cite outdated or vulnerable software as their top security challenge (2026 Hosting Trends Report)
WAF for WordPress
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 one million 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.
Outbound spam getting your mail servers blacklisted
Outbound spam blocked before it reaches the recipient and damages your sender reputation
Imunify Email + Imunify Email Gateway
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.
VPS customers expecting shared-hosting reliability
Shared and VPS on the same tools, training, and support workflow
The CloudLinux VPS Bundle
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.
Hosting providers are already seeing the results.

Esmero
Hands down, the best decision that a web hosting company can make is to incorporate the CloudLinux OS and Imunify360 bundle on their VPS services.
With CloudLinux and Imunify, we do not have many support tickets anymore.
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.
