View company profile

CloudLinux is dedicated to enhancing the security, stability, and profitability of Linux for hosting providers and data centers. With a collective experience of over 500 years in Linux, the company is transforming how these entities utilize the technology, extending its benefits to millions of their customers. CloudLinux boasts over 500,000 product installations and serves more than 4,000 customers, including prominent names like Liquid Web, 1&1, and Dell. The company merges profound technical expertise in hosting, kernel development, and open source with exceptional client care. Cloud Linux, Inc. was consolidated into Cloud Linux Software, Inc., which now operates under the TUXCARE trade name (DBA).

The core offering, CloudLinux OS, is specifically engineered for shared hosting environments. It isolates each tenant into a Lightweight Virtualized Environment (LVE), which partitions, allocates, and limits server resources such as CPU, memory, I/O, and the number of processes. This prevents any single user from monopolizing server resources and causing performance degradation or downtime for other users on the same server. This LVE technology is a key differentiator, ensuring a more stable and reliable hosting environment. CloudLinux OS also incorporates features like CageFS, a virtualized file system that encapsulates each user, preventing them from seeing each other's sensitive information or accessing server configuration files. This significantly enhances security in a multi-tenant setup. Furthermore, HardenedPHP ensures the security of the host system by automatically patching older and unsupported PHP versions. The OS is compatible with major control panels like cPanel, Plesk, and DirectAdmin, facilitating easier adoption and management for hosting providers. Beyond the operating system, CloudLinux has expanded its product portfolio with solutions like Imunify360, a comprehensive security suite for Linux web servers, and KernelCare, which provides automated, rebootless kernel patching. The company also initiated AlmaLinux OS, a free, open-source, community-driven enterprise-grade Linux distribution intended as a CentOS alternative, and continues to sponsor the AlmaLinux OS Foundation.
