Symantec Enterprise Firewall protects enterprise assets and business transactions by ensuring secure connections with the Internet and between networks. As a comprehensive hybrid firewall, it enables controlled connectivity, providing strong and transparent protection against unwanted intrusion without slowing the flow of approved traffic. Through its optional, standards-based Symantec Enterprise VPN it can also provide low-cost, high-speed connectivity between offices and for mobile workers.

Because of its hybrid architecture, Symantec Enterprise Firewall minimizes vulnerabilities and delivers security, ensuring complete control of information entering and leaving the enterprise while providing partners and customers with secure, unfettered access to corporate resources. Its support for a selection of user authentication methods such as Defender, Radius, Digital Certificates, LDAP, and NT domain authentication, gives administrators the flexibility to use existing security databases in the users' environment.

Symantec Enterprise Firewall offers a choice of hardware- or software-based high-availability and load balancing solutions as well as integrated Web content filtering.
