Tidal Cyber Secures $10M to Advance Threat-Informed Defense

Daily Security Review

Cybersecurity startup Tidal Cyber, founded in 2022 by three former MITRE experts, has raised $10 million in Series A funding, bringing its total capital to $15 million. The funding will accelerate the company’s product innovation and expansion, advancing its mission to operationalize the MITRE ATT&CK framework and empower organizations with threat-informed defense.

Unlike traditional security approaches that rely on compliance checklists or vulnerability counts, Tidal Cyber focuses on real-world adversary behavior. Its platform maps tactics, techniques, and procedures (TTPs) used by threat actors, providing defenders with actionable intelligence that goes far beyond indicators of compromise. A standout feature is its Procedures Library, an industry-first repository of real-world adversary actions curated from thousands of technical reports, delivering granular detail on how attackers actually operate.

Tidal Cyber also introduces a rigorous approach to residual risk management, helping organizations understand exposures that persist even after security controls are applied. By continuously calculating residual risk for each adversarial technique, the platform enables defenders to prioritize resources and close gaps against the most relevant threats. This aligns cybersecurity strategy with real adversary tradecraft, rather than abstract frameworks or outdated compliance models.

The funding comes at a time when venture capital in cybersecurity is surging, particularly for AI-powered solutions. With attackers leveraging AI and increasingly sophisticated methods, defenders need platforms that can adapt dynamically. Tidal Cyber’s blend of MITRE ATT&CK operationalization, AI-driven procedural insights, and proactive risk management positions it as a leading player in this transformation.

CEO Rick Gordon emphasizes the shift: “Tidal Cyber flips the security model, putting adversary behavior at the center of defense. Organizations can move beyond assumptions and checkbox compliance toward a truly threat-led defense.”

As organizations grapple with fast-evolving threats, Tidal Cyber’s rise signals a broader industry move toward continuous, proactive, and intelligence-driven security — a necessary evolution in a landscape where attackers innovate daily.
