Features and specs

What each product offers, as listed by its team.

PEX 5 features
CloudLinux 5 features
  • Expense Management
    PEX offers a robust platform for managing expenses, allowing businesses to track and control spending in real-time. This can lead to improved budgeting and financial oversight.
  • Card Control Features
    With PEX, businesses can set specific spending limits, restrict certain merchant categories, and enable or disable cards instantly, providing greater security and control over company expenditures.
  • Integration Capabilities
    PEX integrates with popular accounting and financial software, streamlining the process of expense reporting and accounting, which can save companies time and reduce errors.
  • Mobile App
    The PEX mobile app allows users to manage their expenses on-the-go, providing flexibility and convenience for employees and employers alike.
  • No Credit Check
    PEX cards do not require a credit check for approval, making them accessible to a wider range of businesses, including startups or those with less established credit histories.

Possible disadvantages

  • Fees
    PEX has associated fees, including monthly fees based on the number of active cards, which can add up for businesses with a large number of cardholders.
  • Limited Use Cases
    PEX cards are primarily designed for business expenses and cannot be used for personal banking needs, which limits their versatility compared to traditional corporate credit cards.
  • Fund Preloading Requirement
    PEX operates on a prepaid basis, requiring businesses to preload funds onto cards, which can impact cash flow management compared to using a credit-based system.
  • Lack of Rewards Program
    Unlike some credit cards, PEX does not offer a rewards program, which may be a downside for businesses looking to earn cash back or points on their spending.
  • Customer Support Limitations
    While PEX offers customer support, some users have reported limited customer service hours or responsiveness, which can be frustrating in urgent situations.
  • 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.

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
