About Halcyon
Ransomware will come for your business. Halcyon makes sure it doesn't win. Ransomware has evolved into a human-led operation, with real attackers using AI-powered tools to evade your defenses, destroy your backups, and shut your business down. Halcyon adds a ransomware-native defense layer that catches what generalist tools were never designed to stop, across every stage of the attack chain. And when something gets through, we recover in minutes, not weeks. Turning what could have been a business-ending event into a non-event.
