Tidal Cyber offers a Threat-Led Defense platform that helps organizations measure and improve the effectiveness of their security stack against real-world threats and adversary behavior. The platform operationalizes MITRE ATT&CK and delivers independent tools and services to align security efforts to the threats that matter without vendor bias. Tidal Cyber plans to build a comprehensive CTI and adversary behavior–driven platform to shift organizations from managing intel to proactive, threat-informed defense. The company raised $10 million in Series A funding to accelerate product innovation and fuel company growth. Tidal Cyber was founded in 2022 and is based in Reston, Va. It was co-founded by three former MITRE experts — Rick Gordon, Richard Struse, and Frank Duff — who bring extensive experience in threat-informed defense and related standards and programs. Tidal Cyber offers a Threat-Informed Defense SaaS platform (Enterprise Edition) that aggregates MITRE ATT&CK®, third-party threat intelligence, and internal research to produce Tidal Confidence Scores and Coverage Maps. The platform recently integrated Breach and Attack Simulation (BAS) test results to compare tests against existing confidence scores. The company also maintains a freely available Community Edition used by over 3,000 security professionals globally. Tidal Cyber plans to use new investment to accelerate go-to-market activities, expand sales and marketing, and enhance both Community and Enterprise Editions. The company reported customer and financial growth exceeding 10x over the past year. Founded in January 2022 by threat-intelligence veterans with experience at MITRE and the U.S. Department of Homeland Security, Tidal Cyber aims to lead adoption of Threat-Informed Defense across critical infrastructure segments. Tidal Cyber offers a threat-informed defense platform that embeds the MITRE ATT&CK knowledge base to help security operations teams focus on the most relevant adversarial tactics and techniques. The platform includes a threat profile builder to identify and prioritize relevant threats, a prioritized to-do list for daily defensive actions, a map to optimize defensive tooling, and a proprietary confidence score to assess cyber posture. Tidal’s tools aim to align threats with the right defensive capabilities and streamline communication about an organization’s security program. The company is led by CEO Rick Gordon, CTO Richard Struse, and CINO Frank Duff. Tidal plans to use newly raised capital to accelerate growth of its platform. The company is based in Reston, VA. Tidal Cyber offers a SaaS-based threat-informed defense platform that maps an organization’s security capabilities to adversary tactics and techniques, including MITRE ATT&CK and additional intelligence sources. The platform includes a registry of vendor product capabilities mapped to adversary behaviors to produce actionable insight on defensive coverage, gaps, and overlaps. Tidal provides a free Community Edition that was made generally available at Black Hat USA in early August, featuring enriched technique data and the Tidal Product Registry. The company plans an enterprise edition with enhanced features, including reporting driven by a Tidal Confidence Score to help evaluate and communicate cyber risk reduction. Led by CEO Rick Gordon, Tidal intends to use the new funding to expand the platform and ramp up customer acquisition. Financially, the company raised $4M in funding to support these product and go-to-market efforts.
