Shift5 MIL-STD-1553 Detection Suite
Enterprise defense teams protecting military aircraft and defense platforms need the Shift5 MIL-STD-1553 Detection Suite because it's the only tool that monitors the serial bus itself,the actual data lines where avionics and weapons systems talk to each other,rather than waiting for attacks to surface in logs or network traffic. The suite delivers near-real-time anomaly detection and post-mission forensics across all protocol layers, with direct integration into Electronic Flight Bags and ground stations so threats get escalated where pilots and operators can act on them. This is not for organizations running commercial aviation or non-military platforms; the MIL-STD-1553 bus is specialized hardware, and this tool has zero value outside that ecosystem.
Gambit KnightGuard for OT & Critical Infra
Mid-market and enterprise OT teams managing legacy industrial systems without dedicated threat intelligence will find real value in Gambit KnightGuard for OT & Critical Infra because it consolidates threat-informed defense and continuous monitoring in a single platform rather than forcing you to stitch together separate CTI tools and asset scanners. The hybrid deployment model and strong coverage across NIST ID.RA and DE.CM functions mean you actually get visibility into anomalies without ripping out critical infrastructure to add agents. Skip this if your organization already has mature threat intelligence operations and just needs a narrow detection layer; Gambit's strength is for teams that need the intelligence and monitoring together, not for bolt-on deployments.
