Cybersecurity experts from Halcyon and Sophos have joined forces to establish a new threat intelligence sharing partnership. This collaboration will involve the exchange of crucial data such as indicators of compromise (IoCs), known adversary behaviors, and attack patterns.
Unveiled at the annual Black Hat USA conference in Las Vegas, this alliance between two highly skilled teams aims to combat the ever-evolving ransomware threat landscape by leveraging their combined resources to enhance detection, improve protection, and strengthen response capabilities.
Sophos’ Chief Research and Scientific Officer, Simon Reed, emphasized the importance of timely and relevant intelligence in defending against ransomware attacks. By sharing insights with Halcyon, they aim to enhance detection capabilities and strengthen protection for all their clients.
Halcyon’s CEO and co-founder, Jon Miller, expressed his admiration for Sophos and highlighted their effectiveness in disrupting attackers. The partnership will allow them to leverage Sophos’ innovative features and cutting-edge technologies to stay ahead of sophisticated cyber threats.
In addition to their collaboration, Halcyon recently launched a Ransomware Research Center, while Sophos acquired threat hunting capabilities through the acquisition of Secureworks. This partnership will inform the development of both parties’ solutions, including Sophos Endpoint, Managed Detection and Response (MDR), and Halcyon’s Anti-Ransomware Platform.
Furthermore, Halcyon and Sophos plan to implement mutual anti-tampering protections in their platforms to monitor and safeguard each other’s agents in customer environments. This initiative aims to enhance resilience and protect against ransomware attacks, ultimately strengthening overall cyber protection strategies.
Halcyon also released its quarterly Malicious Quartile ransomware report for the second quarter of 2025, highlighting trends such as the rise of the Akira cyber crime crew and the evolution of attack techniques like Bring-Your-Own-Vulnerable-Driver (BYOVD). The report also noted a shift towards data theft and extortion models among ransomware gangs, underscoring the evolving nature of cyber threats.
Overall, the partnership between Halcyon and Sophos represents a strategic collaboration to enhance threat intelligence sharing, improve defense mechanisms, and stay ahead of emerging cyber threats.
