Its advanced networking, security and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
FreeBSD includes kernel support for stateful IP firewalling, as well as other services, such as IP proxy gateways, access control lists, mandatory access control, jail-based virtual hosting, and cryptographically protected storage.
FreeBSD also includes support for encryption software, secure shells, Kerberos authentication, "virtual servers" created using jails, chroot-ing services to restrict application access to the file system, Secure RPC facilities, and access lists for services that support TCP wrappers.
