| ScanSafe's managed
Web security services are built upon a state-of-the-art network
architecture deploying advanced software for filtering undesirable
Web content and supported by continuous network and service
management. Our scalable, high performance and always available
processing centers scan billions of Web requests each month.
Distributed across multiple data centers, ScanSafe's managed
service infrastructure is sourced from industry-leading suppliers
and designed with inbuilt high capacity, resilience and scalability.
The architecture is configured to maximize redundancy and all
hardware is replicated to avoid single points of failure. Scanning
servers are deployed in a fault tolerant stateless configuration
and our high performance network is implemented using fast,
mirrored drives. Regional load balancing is used to distribute
traffic providing additional resilience and performance. Configuration
provides fully replicated internal redundancy such that no single
point of failure exists. Our track record is continuous 99.999%
availability. For more information on our commitment to maintaining
uptime through comprehensive availability guarantees read more

Traffic Processing Centers:

Global Infrastructure:
In the United States, Europe and Asia we partner with the
largest and most advanced data network providers.
Our network utilizes high-performance route-optimized bandwidth
to the Internet via a proprietary distributed metro NAP architecture
and regional backbone network. With metropolitan SONET rings
connected to multiple Tier-1 backbone providers, and by having
direct private peering with numerous broadband ISPs, backbones
and content providers, ScanSafe takes advantage of the fastest,
most reliable Internet connectivity currently available.

Network and Service Monitoring:
ScanSafe continuously monitors and optimizes the service
to ensure maximum performance and reliability. Automated monitoring
software continuously verifies that all primary and secondary
services are fully operational and that traffic levels are maintained
within expected limits. Virus and Spyware definitions plus content
filtering rules are continuously updated and customers are notified
automatically via email whenever a threat is detected and neutralized.
Any exceptions are notified immediately to our skilled engineers
responsible for service delivery.
