NAIROBI, Kenya, Aug 18 – Cybersecurity firms Sophos and Halcyon have announced a joint initiative to boost ransomware detection and response through real-time intelligence sharing and mutual anti-tamper protections.
The partnership will allow the two companies to exchange threat intelligence data — including indicators of compromise, adversary behaviors, and attack patterns — enabling faster and more informed defense strategies across their security platforms.
The collaboration is expected to benefit more than 300,000 organizations worldwide.
The move follows Halcyon’s launch of its community-focused Ransomware Research Center. Under the agreement, intelligence will be integrated into products such as Sophos Endpoint with Intercept X, Sophos Managed Detection and Response (MDR), Sophos XDR, and the Halcyon Anti-Ransomware Platform.
A key element of the initiative is the introduction of mutual anti-tamper protections, where each platform safeguards the other’s agents within customer systems to prevent ransomware from disabling or interfering with security tools during an attack.
“Ransomware tools and tactics are evolving constantly, and the best defense is timely, relevant intelligence that enables defenders to act quickly and with confidence,” said Simon Reed, Chief Research and Scientific Officer at Sophos.
“By sharing insights with Halcyon, we’re improving signal fidelity and accelerating detection across our systems, which strengthens protection for all the organizations we serve.”
Halcyon CEO and co-founder Jon Miller said the partnership validates his company’s view of Sophos as a leader in endpoint security.
“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 disrupting attackers at a level that outperforms the majority of players in the next-generation antivirus and EDR space,” Miller said.
The initiative will be led by Sophos X-Ops, the firm’s cross-functional threat intelligence team, working with Halcyon’s research and engineering staff to operationalize ransomware-related findings.
Both companies said the collaboration will strengthen defenses across products, improve response times, and enhance resilience against increasingly sophisticated ransomware threats.
