Sophos announced a strategic threat intelligence sharing partnership with Halcyon. This collaboration brings together two of the most experienced teams in ransomware defence to accelerate detection, enhance protection, and improve response capabilities for more than 300,000 organisations worldwide.
The collaboration between Sophos and Halcyon will exchange threat intelligence in real time, including indicators of compromise (IOCs), adversary behaviours, and attack patterns, to enhance ransomware prevention and accelerate response time. Following Halcyon’s recent announcement of a community-focused Ransomware Research Centre, this data-sharing initiative will inform defences across both Sophos’ and Halcyon’s solutions. It will benefit customers using Sophos Endpoint powered by Intercept X, as well as Sophos Managed Detection and Response (MDR), Sophos XDR, Halcyon’s Anti-Ransomware Platform, and other joint capabilities.
As part of the collaboration, Halcyon and Sophos will also implement mutual anti-tamper protections that allow each platform to monitor and safeguard the other’s agents in customer environments. This helps ensure that organisations using both solutions benefit from added resilience, reducing the risk of ransomware interfering with security defences and preserving the integrity of their overall protection strategy.
The threat intelligence collaboration is part of Sophos’ broader strategy to expand the reach and speed of its threat response through strategic partnerships. Sophos X-Ops, the company’s cross-functional threat intelligence unit, will work closely with Halcyon’s research and engineering teams to share and operationalise ransomware-related insights across a wide array of attack surfaces.
“Ransomware tools and tactics are evolving constantly, and the best defence is timely, relevant intelligence that enables defenders to act quickly and with confidence,” said Simon Reed, chief research and scientific officer, Sophos. “By sharing insights with Halcyon, we’re improving signal fidelity and accelerating detection across our systems, which strengthens protection for all the organisations we serve.”
“Halcyon is honored to partner with Sophos. Over the last four years, based on our telemetry, Sophos has time and time again proven to be one of the most effective endpoint security platforms we have encountered, reliably performing and disrupting attackers at a level that simply outperforms the majority of the players in the next-generation antivirus and endpoint detection and response (EDR) space. Their dedication to innovate and roll out industry-leading and unique features continues to put their customers at an everyday advantage over the most sophisticated attacks affecting enterprises today,” said Jon Miller, CEO and co-founder of Halcyon.
Key benefits of the collaboration between Sophos and Halcyon include:
- Real-time ransomware intelligence: Sophos and Halcyon will share timely threat intelligence, including indicators of compromise (IOCs), attacker behaviors, and tools used in active ransomware campaigns. This intelligence supports earlier detection, broader visibility, and more informed responses.
- Strengthened defences across products and services: Shared intelligence will enhance threat detection models, enrich contextual telemetry, and accelerate protection updates within each company’s solutions, including Sophos Central and Halcyon’s Anti-Ransomware Platform.
- Mutual anti-tamper protections: Each solution actively monitors the other’s agents to prevent tampering or disablement during ransomware attacks, helping ensure that security defences remain intact and effective throughout an incident.
This collaboration highlights Sophos’ and Halcyon’s continued commitment to cybersecurity innovation, industry cooperation, and the mission to defeat cybercriminals. Together, Sophos and Halcyon are delivering the intelligence needed to stay one step ahead of attackers.
