Halcyon Introduces File Resilience to Combat Ransomware Encryption

On July 28, 2026, Halcyon launched File Resilience (FiRe), a new feature designed to prevent ransomware encryption before it occurs. Operating at the Windows kernel level, FiRe intercepts encryption attempts, making successful attacks virtually impossible. This new capability is part of Halcyon's ransomware resilience platform, which now includes native support for macOS and enhanced integrations with Microsoft Defender and Microsoft Sentinel. The system aims to keep organizations operational during ransomware attacks by terminating encryption attempts immediately. Halcyon emphasizes that this proactive approach differs from traditional security tools that focus on detection or recovery. The feature is available immediately, with macOS support expected in August 2026. Halcyon will showcase these advancements at Black Hat USA 2026.

Key Points: • Halcyon's File Resilience prevents ransomware encryption at the Windows kernel level. • The new feature is designed to keep businesses operational during ransomware attacks. • Enhanced integrations with Microsoft security tools are now available.
