Features and specs

What each product offers, as listed by its team.

Hudson Rock 8 features
CloudLinux 5 features
  • Compromised Employees
  • Compromised Customers & Users
  • Compromised Supply Chain
  • Compromised Android Users
  • Compromised Leaked Database
  • Compromised CXO’s & Family Members
  • Assets Discovery (Shadow IT)
  • Supply Chain Risk Assessment
  • 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.

Overall verdict

  • CloudLinux is a well-regarded, mature Linux OS distribution and toolset specifically designed for shared hosting and multi-tenant server environments, offering strong isolation, resource management, and security features that make it a solid choice for hosting providers.

Why this product is good

  • Provides LVE (Lightweight Virtual Environment) technology for per-tenant resource isolation, preventing 'bad neighbor' effects on shared servers
  • Enhances server stability and security by isolating users so that one account's issues (crashes, resource spikes) don't affect others
  • Offers extended lifecycle support (longer than standard CentOS/RHEL support windows), which is valuable for legacy systems
  • Includes tools like CloudLinux OS Shield, Imunify360 integration, and hardened kernel options for improved security
  • Compatible with popular control panels like cPanel and Plesk, making it easy to integrate into existing hosting stacks
  • Backed by an established company with a long track record in the hosting industry and responsive support
  • Offers granular control over CPU, memory, I/O, and other resources per user account
  • Provides PHP Selector and multiple PHP version support, useful for hosting providers serving diverse client needs

Recommended for

  • Web hosting companies running shared or reseller hosting environments
  • Hosting providers needing to isolate customer accounts on the same physical server
  • Businesses requiring extended OS support lifecycles beyond standard RHEL/CentOS EOL dates
  • Enterprises using cPanel or Plesk that want tighter security and resource control
  • Hosting companies looking to reduce support tickets caused by noisy-neighbor resource contention
  • IT teams managing multi-tenant infrastructure who need governance and monitoring tools built into the OS layer

Questions & Answers

As answered by people managing Hudson Rock and CloudLinux.

Why should a person choose your product over its competitors?

Hudson Rock's answer

Many cybercrime intelligence intelligence platforms aggregate data from publicly available database leaks, whereas Hudson Rock does not pursue generally available credentials as its main goal. Publicly available databases enable finding old or unrelated credentials by the same user, leaving the hacker to check if they were reused in other, more sensitive services that they’re trying to access. We consider this information to be less valuable, for several reasons:

  1. Time - stolen credentials are usually published (for free) after hackers think the leads are not very valuable. This is usually AFTER the actionable threats occurred. Hudson Rock integrates data from compromised computers merely days after they were compromised, and at the same time they are obtained by sophisticated threat actors attempting to perform data breaches and ransomware attacks.
  2. Relevancy to clients - data from info-stealers is the most prominent attack vector used by sophisticated hacking groups to obtain initial access to company servers, or to overtake end-user accounts, the data is unrivalled because hackers are able to bypass traditional security measures such as 2 factor authentication by injecting cookies from the compromised computers, or finding the backup codes for revoking the 2 factor authentication stored on the compromised computer.
  3. Password reuse dependency - While password reuse is an issue, employees don't tend to reuse passwords to critical infrastructure across different services and end users don’t always reuse passwords across all services they use. The passwords originating from leaked databases are not remotely as impactful as passwords stolen from the browsers of the victims where there is a direct link between the domain they browsed into and their emails and plaintext passwords. This is because when a victim has had a stealer executed on their machine, all the domains, emails, usernames, and passwords they have ever used are captured. This is because when a victim had a stealer executed on his machine, all the domains, emails, usernames, and passwords they have ever used are captured.

What makes your product unique?

Hudson Rock's answer

Every credential presented in Cavalier was stolen directly from the browsers of victims who had a stealer type malware executed on their machine. These malwares are spread by tricking a victim to download a malicious file through various methods. the attacks are usually performed by threat actors in global opportunistic campaigns, with little discretion, so employees in companies that aren't even targeted often have their corporate credentials stolen.

Hudson Rock acquires and purchases compromised information directly from top-tier threat actors, and closed circle hacking groups. What sets this information apart, is its low availability in other high-fidelity threat intelligence companies, and its high accessibility to hacker groups looking for potential targets. Our operational knowhow, and our boots-on-the-ground approach to cybercrime comes from the IDF's 8200 Cybercrime division, and its efforts to thwart nation-state adversaries and professional threat actors.
