REDCOM adds FIPS 140-3 cryptography and a redesigned Windows client to Sigma 4.4

REDCOM Laboratories has released Sigma 4.4 and Sigma Client for Windows 6.4, adding a grid-based control view, expanded radio status reporting, and FIPS 140-3 validated cryptography. The updates are aimed at giving tactical users a single application for voice, PTT, video, and chat at the edge. Why it matters: - REDCOM is targeting tactical teams that need to manage voice traffic, push-to-talk, video, and chat from one interface instead of switching between apps. - The new release is designed to reduce friction during time-sensitive operations where users need faster access to communication controls. - FIPS 140-3 validated cryptography adds a security upgrade for environments that require certified encryption. What happened: - REDCOM Laboratories released Sigma 4.4, its flagship C2 communications platform, along with Sigma Client for Windows 6.4. - The company says the updates strengthen Sigma as a unified platform for command and control voice traffic at the tactical edge. - John Kelliher, REDCOM’s director of strategy and R&D, said the new layout is intended to cut delays caused by juggling multiple applications. The details: - The Windows client now uses a grid-based channel view that puts channels, radio status, PTT controls, video, and chat messages on one pane of glass. - Users can drag and drop widgets to customize the layout. - The client adds improved integration with external PTT devices and headsets. - A visual indicator shows the current talker. - Channels can be muted or unmuted individually. - Users can send PTT to a single channel, a group of channels, or all channels at once. - Radio connectivity now reports real-time status to channel clients. - Status details include radio presence and connectivity, plaintext or ciphertext state, preset number and name, and waveform information. - The release includes FIPS 140-3 validated cryptography. - REDCOM also points users to a features overview video and a Sigma 4.4 Feature List PDF for more detail. - REDCOM says its tactical products are optimized for low size, weight, and power use and are built for denied environments and deployment to the tactical edge. - REDCOM says its customers include military branches, government agencies, emergency responders, integrators, and enterprises. - REDCOM says all products are designed, built, and supported in the United States. Between the lines: - The release pairs user-interface simplification with stronger encryption, suggesting REDCOM is trying to serve both usability and security needs in the same update. - The emphasis on radio presence, cipher state, and waveform details points to workflows where operators need immediate situational awareness, not just basic call control. - The single-pane design is a clear signal that REDCOM is competing on workflow consolidation, not only on communications hardware or protocol support. What’s next: - REDCOM is steering users to the feature overview video and the Sigma 4.4 Feature List PDF for a closer look at the new capabilities. - The company is likely positioning Sigma 4.4 and Sigma Client 6.4 as the latest baseline for tactical unified communications deployments. - REDCOM’s broader message is that future edge communications tools will need to combine secure voice control with simpler operator workflows.
