Tidal Cyber

Tidal Cyber is a cybersecurity company founded in 2022 by former MITRE ATT&CK experts and the co-founder of MITRE's Center for Threat-Informed Defense, built to make threat-led defense practical and sustainable for enterprises of all sizes. The company's platform maps real-world threats to MITRE ATT&CK frameworks, enabling security teams to justify security investments by showing which tools can defend against specific threats and which cannot. Tidal Cyber's Enterprise Edition helps organizations adopt a threat-informed defense posture by correlating threat intelligence with security tool coverage and capability gaps. The company is backed by leading cybersecurity investors and has partnerships with organizations including The Chertoff Group. Headquartered in Clifton, Virginia, Tidal Cyber raised $10 million in a Series A funding round in 2025.
