Software Development Estero, Florida 51–200 employees Founded 2009 Privately Held

CloudLinux builds a commercially supported Linux OS and security tooling for shared hosting providers and datacenters, with deep integrations into cPanel, Plesk and DirectAdmin. Active work on KernelCare live patching, CVE patch-testing automation and SecureChain supply-chain security shows a pivot toward patch and supply-chain security, while Terraform and Ansible adoption plus senior-heavy engineering hiring point to infrastructure-as-code maturation.
