Features and specs

What each product offers, as listed by its team.

CloudLinux 5 features
Passary 9 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.
  • Zero-Knowledge Architecture
    Passary never sends or stores any password data on servers; all encryption happens locally.
  • AES-256-GCM Encryption
    Strong symmetric encryption for securing all stored credentials.
  • Argon2id Key Derivation
    Modern password-based key derivation to protect the master password from brute-force attacks.
  • Local Vault Storage
    Vaults are saved directly on the user’s local filesystem using the File System Access API.
  • No Accounts Required
    No registration, syncing, or cloud infrastructure; nothing is transmitted externally.
  • Secure Password Generator
    Built-in generator for strong, customizable passwords.
  • Auto-Lock and Timeouts
    Vault automatically locks after inactivity for improved security.
  • Modern, Lightweight UI
    Fast, minimal interface built with React and Next.js.
  • Open Security Model
    Designed so users maintain full control over their encrypted vaults with complete transparency.

Analysis

Passary

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

Overall verdict

  • Passary appears to be a password management and digital security tool, but limited independent verification and third-party reviews are available, making it difficult to fully confirm its reliability, security standards, and overall performance compared to more established competitors in the space.

Why this product is good

  • May offer password storage and management features
  • Could provide a straightforward user interface for organizing credentials
  • Might include basic security features like encryption
  • Potentially offers a lower-cost alternative to premium password managers

Recommended for

  • Users seeking a lesser-known password management alternative
  • Individuals wanting basic credential organization without extensive features
  • Those willing to research and verify security credentials independently before committing
  • Budget-conscious users exploring simpler password management solutions

Questions & Answers

As answered by people managing CloudLinux and Passary.

What makes your product unique?

Passary's answer:

Passary is built around a strict offline-first, zero-trust philosophy. All vault data is encrypted and stored locally on the user’s device, never synced to the cloud, and never processed by external servers. This approach eliminates common risks associated with centralized password managers and provides a simpler, more predictable security model. Passary combines modern cryptography with a lightweight, privacy-focused design that requires no account, no tracking, and no internet connection to function.

Why should a person choose your product over its competitors?

Passary's answer:

Users who value maximum privacy and full control over their data choose Passary because it never transmits, stores, or syncs passwords to any server. There is no cloud, no account, and no central storage to compromise. Passary uses strong encryption, a zero-knowledge architecture, and a minimal attack surface, making it ideal for people who want a password manager that remains entirely under their control. It is also lightweight, easy to use, and avoids the complexity found in many cloud-based tools.
