Security and Redundancy


Security at CellTrust

The CellTrust Data Centers provide a secure computing environment suitable for hosting critical applications and sensitive data. Physical and environmental controls protect the computer room itself from interruptions and unauthorized intrusions, while technical controls on all platforms protect applications and data from unauthorized disclosure and manipulation. CellTrust Data Centers have uninterruptible power supplies (UPS,) physical access control procedures, and climate control. Central backup and recovery systems, a disaster recovery program, and security management and operations procedures for all platforms ensure the confidentiality, integrity, and availability of customer applications and data. The Data Centers' staff members manage and monitor all host systems to guarantee continued availability and effective operations. CellTrust's security management program continually reviews and refines its security operations.

Redundancy at CellTrust

Gateways are judged by their ability to provide continuous operations for the network services they support. Gateway availability is affected by both planned (scheduled maintenance) and unplanned events (e.g., failures.) To maximize availability, the impact from each of these events must be minimized and/or eliminated. The CellTrust Gateway is maintained on a regular basis. During these planned outages, customers are switched to the secondary data center to eliminate any downtime. To mitigate unplanned outages, both redundancy and fault-tolerance are incorporated into the CellTrust Gateway. High-availability is accomplished by providing redundancy for all systems, thereby eliminating single points of failure. Additionally, our data centers offer predictable uptime by incorporating fault-tolerance against hard failures. (A hard failure is a failure in which the component must be replaced to return to an operational steady state.) The CellTrust Gateway achieves high-availability by implementing a fully redundant, fault-tolerant, and concurrently maintainable IT and support infrastructure architecture in which all possible hard failures are predictable and deterministic.
