About Tidal Cyber

Tidal Cyber helps security teams decide where their defenses fall short against the attackers most likely to target them.

Its platform holds a library of adversary procedures mapped to MITRE ATT&CK and calculates residual risk for each technique based on the tools a company runs. An AI engine the company calls NARC turns unstructured threat reports into ATT&CK-aligned procedures.

Integrations with defensive tools and breach and attack simulation products validate coverage. A free Community edition sits alongside the Enterprise product. Tidal Cyber is based in Washington, D.C. and was founded in 2022 by former MITRE staff.
