Sevan Networks Logo Identity Authentication for Web Security
home solutions products white papers about us
"The product relies on public key authentication to increase user convenience and strengthen security. However, deployment and management are simple and the cost of ownership is low because the product doesn’t require an infrastructure like other public key based solutions."

Scalable Performance and Reliability

As required by good security practices, the WSA isolates the web site from all networks. Any traffic going to or from the web site must pass through the WSA. The WSA's clustering feature ensures that the WSA will never throttle your site's performance or bring your site down.

In situations needing improved performance or enhanced availability, two or more WSAs can be installed "in parallel" as a cluster. The WSAs in the cluster share the load, so the capacity of the cluster is greater than the capacity of a single WSA. The WSAs also monitor each other so in the unlikely event that a WSA fails, the surviving WSAs pick up its traffic.

Adding a WSA to a cluster is as simple as cabling. The WSA requires no special clustering hardware or software. A cluster of WSAs is administered as a single unit, so the WSAs automatically share configuration, security policy, user information, and logs.


  • Clustering increases the performance of the WSA

  • Clustering enhances the availability of the WSAs by adding n-way redundancy

  • Forming a WSA cluster is as simple as adding a WSA - no special hardware, software, or configuration.
