SSL VPNs are evolving in a manner similar to IPsec technology. This technology started as dedicated VPN concentrators and slowly became integrated with other network and security services. Two types of SSL VPN solutions are on the market: the pure-play SSL VPN appliances and the solutions that integrate SSL VPN functionalities with other network devices such as routers and firewalls. The emerging Unified Threat Management (UTM) market provides enterprises with options to deploy a single security device that offers multiple security services such as a firewall, a VPN, an IPS, antivirus and antispam software, and other content security services. Each solution has its merits and deployment benefits. Cisco offers the integrated solution with Cisco routers and Adaptive Security Appliances (ASA). A UTM appliance, the Cisco ASA appliances allows security administrators to deploy additional security services to the SSL VPN traffic.
