🟢 EXECUTIVE INSIGHTS

📣 VENDOR SPOTLIGHT

Spotlight Rationale

Today’s most impactful news is the discovery of a backdoor in the TETRA radio encryption standard, affecting critical communications for police, military, and OT environments. This is not a traditional IT threat; it exists in the specialized world of cyber-physical systems. Therefore, we are spotlighting Armis, a leader in asset intelligence and security for IoT, OT, and ICS environments. Their recent acquisition of OT security specialist Otorio, combined with their core competency in identifying and profiling connected devices, makes them uniquely suited to address this specific, emergent threat.

Threat Context: Backdoor in Widely Used Radio Encryption Standard

Platform Focus: Armis Centurion

Summary & Significance: Armis Centurion is designed to discover, classify, and assess the security posture of every connected asset, including specialized radio equipment that uses the TETRA standard. Unlike traditional IT security tools, Armis can passively monitor network traffic (including wireless spectra) to identify these devices, flag them as running a vulnerable protocol, and alert security teams to the risk of eavesdropping, even when the devices can't host a traditional security agent.
