iDirect Government Debuts Evolution Defense 4.4 Software with Enhanced Security

Complete CSIR™ Interference Mitigation Solutions Round Out Security Features for MILSATCOM

Herndon, Va., November 30, 2021 – iDirect Government (iDirectGov), a leading provider of satellite communications to the military and government, today announced its newest software release, Evolution® Defense 4.4, for enhanced military satellite communications (MILSATCOM) protection.

Evolution Defense 4.4 technology advancements are targeted at the DLC-R line cards, enabling Communication Signal Interference Removal (CSIR™) on the DLC-R line cards, and other security improvements.

CSIR represents a real-time streaming technology to mitigate interference, and the introduction of Evolution Defense 4.4 now applies to both iDirectGov’s remote and line cards. This release complements the previous Evolution Defense software release, which provided CSIR protection on the 9-Series, establishing a complete end-to-end interference mitigation solution.

The DLC-R and 9-Series remote interference reporting work in the company’s iMonitor network management software, which provides in-depth views into both real-time and historical network performance. This includes the health status of remotes, graphical displays, network probes and detailed bandwidth usage. The DLC-R-measured interference alerts and warnings thresholds are user configurable, as are the satellite remote alerts and warnings.

With security as the highest priority for iDirectGov, the Evolution Defense platform is continuously tested and evaluated to ensure mission critical data is protected. To reinforce this security posture, the deployment of the Evolution Defense 4.4 software will have the protection of the Federal Information Processing Standards (FIPS) 140-2 Level 1, enabled along with the backing of the security enhancements in Red Hat Enterprise Linux 8 (RHEL8). This implementation is applicable to all the servers associated with the platform beginning with Evolution Defense 4.4.

“Enhanced security solutions in Evolution Defense 4.4 create a multi-layered approach to MILSATCOM protection,” said John Ratigan, President of iDirect Government. “We have engineered this specialized software release to enable interference mitigation on our line cards to create an end-to-end solution for interference when combined with our 9-Series remotes.”

These security enhancements help to combat adversaries who are increasing their implementations of signal intelligence (SIGINT) to attack military and government spectrum use, as enemies seek to jam transmissions intended for radio communications, radar and various operations.

“Evolution Defense 4.4 meets military communications requirements worldwide,” said Ratigan. “Our security solution offers a Defense-in-Depth approach for reliable and secure communications.”
