Features and specs

What each product offers, as listed by its team.

CloudLinux 5 features

resilienceOS 8 features

Enhanced Server Stability
CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
Improved Security with HardenedPHP and KernelCare
CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
Resource Limit Management
Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
CageFS File System Virtualization
CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
Wide Compatibility with Hosting Panels
CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

Additional Licensing Cost
CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
Limited to CentOS/RHEL-Based Systems
CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
Learning Curve for Configuration
While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
Potential Performance Overhead
The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
Dependency on CloudLinux Ecosystem
Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.

Questions & Answers

As answered by people managing CloudLinux and resilienceOS.

Why should a person choose your product over its competitors?

resilienceOS's answer:

We are born from deep operational 'on the ground' experience and expertise across multiple markets, specifically for crisis response management.

This hands-on experience and knowledge informs our product road-map, allowing us to focus on the things that we KNOW matter, and actually make a critical difference.

Given our global response centre service in Aberdeen, and 80% of operators in the Red Sea using our service, we have the ability to continuously learn from all incidents that occur, and improve our software based on these learnings.

What makes your product unique?

resilienceOS's answer:

We are the only risk management solution to provide a truly unified and open data ecosystem, that allows multiple third-party risk data sources to be integrated and displayed in one single dashboard (no data siloes, no system hopping).

Location Convergence: We take multi-sourced data from HR feeds, travel itinerary systems, access control data, GPS data, etc. and use this data to calculate and present the most accurate picture of where your people are at any given time.

Modular capability: We give organisations the option to deploy our solutions on a scalable level. Starting from a single site location, with the ability to expand on to: country, region, and even completely global.

24/7 Monitoring & Response: Restrata works with organisations around the world to effectively and efficiently manage incidents of every size and nature. Our Global Operations Command Centre (GOCC) sets the standard for round-the-clock international response. Headquartered in the UK with a secondary incident management centre in Dubai, we're well-positioned to respond to any incident regardless of when and where it may occur.

How would you describe the primary audience of your product?
