Halcyon Anti-Ransomware & Cyber Resilience Platform is paid security software focused on ransomware from pre-execution through data exfiltration and encryption. Its AI models draw on ransomware signals, samples, tactics, techniques, procedures, playbooks, and incident-response engagements. A behavioral engine uses threat modeling, anti-detonation, and deception exploitation to detect ransomware activity. Halcyon can capture symmetric encryption keys and decrypt affected data to restore files. Data Exfiltration Protection detects unusual movement, including unauthorized file-sharing services, cloud tunneling, and known malicious command-and-control infrastructure. EDR Tamper Detection monitors attempts to evade or disable endpoint detection and response tools. Each deployment includes a 24/7/365 Ransomware Operations Center to investigate alerts, respond to threats, and lead recovery at no additional cost. If an attack breaches its defenses, the warranty includes expert-led response and recovery at no additional cost, with a stated minimum value of $50,000. Halcyon works alongside endpoint products including Microsoft Defender, CrowdStrike Falcon, SentinelOne Singularity, and Palo Alto Cortex XDR. Pricing is on request and there is no free plan. Supported platforms include Windows, Linux, and web.

Halcyon is aimed at mid-market and enterprise customers seeking ransomware prevention and response, with a separate deployment option for small and midsize businesses. It may suit organizations that already use endpoint products and want a platform that works alongside them.
