Features and specs

What each product offers, as listed by its team.

AuthKong 5 features
CloudLinux 5 features
  • User-Friendly Interface
    AuthKong provides an intuitive and easy-to-navigate interface that simplifies user management for both developers and administrators.
  • Scalability
    The platform is designed to handle a large number of users and authentication requests efficiently, making it suitable for growing companies.
  • Robust Security Features
    Offers strong authentication protocols and encryption standards to ensure user data is protected from unauthorized access.
  • Comprehensive Documentation
    AuthKong provides thorough and well-organized documentation that helps developers integrate authentication services seamlessly into their applications.
  • Customizable Authentication Flows
    Allows businesses to tailor authentication flows to suit their unique needs, enhancing user experience and security.

Possible disadvantages

  • Cost
    AuthKong may have a higher price point compared to other authentication solutions, which could be a barrier for small businesses or startups.
  • Learning Curve
    Despite its user-friendly design, some advanced features require a learning curve for new users who are unfamiliar with authentication systems.
  • Limited Integrations
    While AuthKong supports many popular integrations, it might lack connectivity with some less common or niche platforms.
  • Technical Support
    Some users have reported delays in receiving technical support, which can be critical during implementation or troubleshooting.
  • Dependency on Internet
    As a cloud-based service, it requires a reliable internet connection for optimal functionality, which might be challenging in areas with unstable internet access.
  • 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.

  • 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
