Six Capability Areas.
Two Engines.
One analyst-led platform. The face engine reads behavioural signals from existing cameras; EchoDepth Signal reads language. Select a solution area below to explore the use case, capabilities, and deployment options in detail.
EchoDepth is a behavioural threat intelligence platform developed by Cavefish in Cardiff, Wales. Its face engine analyses 44 FACS-compliant facial Action Units in real time to detect stress, deception, cognitive overload, and operator fatigue, with no wearables, no physical contact, and no disruption to existing workflows. EchoDepth Signal analyses language, and is being extended to narrative and influence-tactic analysis and crisis communications testing with design partners.
