Morae and Halcyon Announce Strategic Partnership

Nov 6, 2025

News provided by Share this article Strengthening Cyber Resilience and Security in the Legal Industry HOUSTON, Nov. 6, 2025 /PRNewswire/ -- Morae, the global leader in digital and business solutions for a constantly changing legal industry, today announced a strategic partnership with Halcyon, the leading anti-ransomware solution provider. This collaboration provides law firms and corporate legal teams with a powerful cyber defense, combining Halcyon's best-in-class technology and advanced ransomware detection and recovery capabilities with Morae's legal and information governance expertise. Together, this will ensure clients safeguard sensitive information, ensure regulatory compliance, including GDPR and ISO 27001, build trust and maintain operational continuity. Halcyon Company Logo Press Release Ransomware is one of the most damaging and disruptive cyber threats facing organizations today — and the legal sector is a prime target due to the uniquely high-value, confidential information for which law firms and legal teams are responsible. Research shows that from 2018 to now there have been 195 reported ransomware attacks on legal organizations, impacting more than 2.9 million records and with an average ransomware demand of $2.5 million. With the financial and reputation damage this can cause, it is critical for legal leaders to stay ahead of the threat, protect client data and maintain multi-jurisdictional compliance with global information governance regulations and insurance requirements. Despite this need, traditional security tools often detect ransomware or alert users when it is too late, leading to catastrophic data loss and operational disruption. The Morae–Halcyon partnership takes a fundamentally different approach: it's built for resilience, disruption and rapid recovery, providing legal organizations with end-to-end solutions, delivering tangible, mission-critical benefits: Reduced risk: Ransomware is contained before business impact. Uses advanced AI and behavioral detection to identify and neutralize ransomware signals early, stopping an attack before it spreads. Continuity: Systems and data are restored quickly, minimising downtime and disruption. Resiliency layers ensure business-critical data remains safe, accessible and recoverable. Confidence: Boards, clients, regulators, and insurers know ransomware resilience is built in. Captures intelligence from every attack attempt, continuously improving future protection and contributing to a broader cyber defense ecosystem. "Legal professionals manage some of the most sensitive information in the world therefore excellent information governance and security is not just a compliance requirement — it's a business imperative." said Keith Fenner, Chief Revenue Officer at Morae. "Our clients have must have the highest level of protection and resilience, ensuring their data remains secure across all stages of the information lifecycle - even in the face of today's sophisticated cyber threats. Our partnership with Halcyon means we can offer exactly that."
