Cloud Linux Inc. product offering
Product offeringCore offering
CloudLinux develops and sells a Linux-based operating system platform and security software suite engineered specifically for shared and VPS web hosting providers. Its core product, CloudLinux OS, isolates tenants and allocates CPU, IO, memory, and database resources per user, while Imunify360 and the TuxCare family provide malware protection, WAF, firewall, rebootless kernel patching, and lifecycle support for end-of-life open-source software.
Product overview
CloudLinux offers a comprehensive portfolio of products organized around three main pillars: CloudLinux OS (the foundational operating system for shared hosting stability and multi-tenant isolation), Imunify360 (the flagship security platform covering malware scanning, WAF, firewall, and email security), and TuxCare (kernel and software lifecycle management including KernelCare rebootless patching, Endless Lifecycle Support for EOL software, and Radar vulnerability scanning). The product architecture is platform-plus-modules: CloudLinux OS serves as the core OS with integrated features like LVE Manager for resource allocation, CageFS for tenant isolation, and MySQL Governor for database throttling; Imunify360 is the umbrella security brand with specialized add-ons including ImunifyAV/AV+ (malware scanner), Imunify Email (spam filtering), Imunify Patch (auto-patching), Imunify Connect (SDK for developers), and Imunify Security for WordPress (WAF); and TuxCare services extend the security story to kernel and application patching. Performance optimization is handled through AccelerateWP (WordPress optimization suite) and MAx Cache (Apache/Nginx caching module). The VPS Bundle packages CloudLinux OS with Imunify360 for VPS providers, while Imunify for AI Agents addresses emerging security needs for AI agent workloads.
