Features and specs

What each product offers, as listed by its team.

CloudLinux 5 features
Prolyz 5 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.
  • Real-time CDC
    Log-based change data capture streams every insert, update and delete the moment it is committed, across 50+ connectors.
  • Built-in OLAP analytics
    ClickHouse engine included: interactive reports and ML forecasting on live data, with no separate warehouse to stand up.
  • Causal AI
    Causal inference (Pearl, DoWhy) explains why a number moved, not just that it did, with the reasoning attached.
  • Privacy-first local AI
    All AI reasoning runs on a local model inside your environment. Neither data nor metadata leaves it. GDPR and KVKK aligned.
  • Governed catalog & lineage
    Every asset cataloged with column-level lineage, quality scoring, quarantine rules and domain ownership.

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 CloudLinux and Prolyz.

What makes your product unique?

Prolyz's answer:

Three things that rarely ship together in one platform:

  • Built-in OLAP. A ClickHouse engine is part of the product, so interactive analysis and ML forecasting run on live data with no separate warehouse to stand up.
  • Causal AI, not correlation. Prolyz Agent uses causal inference (Pearl's framework via DoWhy) to isolate why a number moved, and returns the reasoning with the answer.
  • Privacy-first local AI. All reasoning runs on a model inside your environment. Neither data nor metadata leaves it, which is what makes on-premise and air-gapped deployments possible.

Underneath, four governed layers hand data to each other: Data (catalog, lineage, quality), Sync (real-time CDC and ETL), Report (OLAP analytics) and Agent (decisions).

Why should a person choose your product over its competitors?

Prolyz's answer:

It depends on what you already run, and we try to be honest about that.

  • Against pipeline tools (Fivetran, Airbyte): they move data into a warehouse you still have to buy, model and report on. Prolyz moves it and then governs, analyses and explains it in one platform.
  • Against enterprise suites (Informatica): they are deeper in master data management, but reporting and reasoning live in other vendors' tools. Prolyz ships built-in OLAP and causal AI.
  • Against BI (Power BI, Tableau): a dashboard shows what changed. Prolyz Agent traces why, with causal inference rather than correlation.

And one hard requirement others rarely meet: everything, including the AI, can run on-premise or air-gapped, with no data or metadata leaving your environment.

How would you describe the primary audience of your product?

Prolyz's answer:

Data and analytics teams in mid-market and enterprise organisations that run business-critical systems (SAP, CRM, operational databases) and are expected to answer questions faster than a nightly batch allows.

Typical buyers: heads of data, BI and analytics leads, data engineers and CTOs. The strongest fit is regulated sectors, finance, insurance, healthcare, public sector and manufacturing, where data has to stay on-premise or in-country and every number needs an audit trail.

Common starting point: a team that already has dashboards, but where the question "why did this change?" still takes days.

What's the story behind your product?

Prolyz's answer:

Prolyz was founded in 2026 by two engineers who had spent years building data platforms for enterprises, and kept watching the same thing happen: the pipelines worked, the dashboards were accurate, and nobody could say why a number moved. Answering that took days of exports, meetings and guesswork.

The second pattern was regulatory. In finance, insurance and the public sector, the answer to "can we send this data to a cloud model?" was simply no, which ended most AI projects before they started.

So Prolyz was built around two commitments: reason about causes rather than correlations, and do it entirely inside the customer's environment. The company is registered in London as Prolyz Ltd, with engineering in Istanbul.

Which are the primary technologies used for building your product?

Prolyz's answer:

  • Services: .NET 8 microservices behind a YARP gateway, OAuth 2.0 / OIDC via OpenIddict, RabbitMQ and MassTransit for events.
  • Data path: PostgreSQL for OLTP, log-based CDC into ClickHouse for OLAP, Redis for cache, Qdrant for vector search.
  • AI: Python and FastAPI with DoWhy for causal inference and local LLMs (Ollama) so nothing leaves the customer's environment; MCP servers pull external context.
  • Frontend: React and Next.js.
  • Operations: Docker and Kubernetes with Helm, OpenTelemetry, Prometheus, Grafana, Loki and Tempo.

Deployment: managed SaaS, hybrid, or fully on-premise and air-gapped, from the same codebase.
