Self-Contained, Hardened Appliance

The twin demands of strong security and low cost of ownership require a self-contained, hardened appliance. This is important since strong security requires simplicity of installation and operation: every point of contact between a security device and the outside world is a point of vulnerability and error. Simplicity and the absence of external hardware or software also leads to low cost of ownership.

The WSA is designed as a hardened device using the best security principles. For example, the WSA uses a simplified, real-time operating kernel. All of the WSA's critical functions like protocol handling and web services were implemented by Sevan, and all sensitive data is encrypted.

Benefits:

• A self-contained appliance is easy to install: no integration or reliance on external devices

• The simplicity of a self-contained appliance is the basis for realistically strong security. There are simply fewer things to go wrong

• A hardened appliance provides security that you can trust. The appliance, rather than your servers, takes the brunt of hacker attacks
