Reliability

 

We understand the critical nature of email communications and the importance of providing filtering that is effective and reliable.

The robust network and software architecture were designed to handle both the rapidly growing volume of email and the heavy peak loads that are characteristic of SMTP traffic. Scalability is due to several elements including:

• A proven, highly optimized software architecture with fully automatic, real-time message processing

• Parallel systems architecture (fully redundant sets of systems running in parallel)

• Redundant, geographically distributed datacenters with 24x7 security guards, video surveillance, and biometric security measures

• Fault-tolerant local network architecture at each datacenter

• Robust UPS systems and diesel backup (with enough fuel on-site to provide power at full load for over a month)

• 24x7 automated systems and full-path monitoring from multiple locations

The result is an email security solution that has no single point of failure and that can comfortably scale to meet the needs of large enterprises, Internet Service Providers, and other high-traffic customers.

With a 99.999% uptime guarantee, customers can depend on the network for true messaging continuity.
