Tidal Cyber Inc.

Tidal Cyber is a private cybersecurity company headquartered in Reston, Virginia. Founded in January 2022 by former MITRE experts, its core mission is to make threat-led defense practical and sustainable for all enterprises. The company aims to empower organizations to assess, organize, and optimize their cyber defenses by aligning security efforts to real-world threats and adversary behavior, primarily leveraging the MITRE ATT&CK framework.

Tidal Cyber offers a platform that includes both a free Community Edition and an Enterprise Edition, along with products like NARC AI and integrations. Key services include custom threat profiling, coverage mapping, and MITRE ATT&CK® product mapping. Their solutions are designed for Security Operations Center (SOC) teams, detection engineers, threat intelligence and research teams, red/purple teams, and threat hunters, serving market segments such as financial services, healthcare, critical infrastructure, and the public sector. The platform helps organizations understand how their existing defensive stack performs against adversary tactics, techniques, and procedures (TTPs).

The company was co-founded by Rick Gordon (CEO), Richard Struse (CTO), and Frank Duff (CINO), all of whom have extensive backgrounds from MITRE. In September 2025, Tidal Cyber raised $10 million in Series A funding, bringing its total funding to $15 million, with investors including Bright Pixel Capital, Capital One Ventures, Squadra Ventures, and USAA. More recently, in December 2025, they released their 1st Annual Threat-Led Defense Report, and in February 2026, they announced a redefinition of Threat-Led Defense to focus on adversary procedures. CTO Richard Struse was also appointed to the MITRE ATT&CK® Advisory Council in March 2026. Tidal Cyber positions itself as a leader in Threat-Led Defense, emphasizing the operationalization of adversary procedures to enhance cybersecurity resilience.
