Why Halcyon Exists

Ransomware isn't just another threat.
It's a different category of attack.

1

It moves faster than you can

Ransomware collapses your response window — forcing irreversible decisions before your team can coordinate. By the time a detection fires, the leverage is already established.
49%
of victims detected their last attack too late to prevent significant damage — despite 100% expressing confidence in their detection capabilities. *
2

It shuts down your business

Every other threat aims to compromise your environment. Ransomware aims to shut down your business and hold it hostage until you pay. Stopping it requires more than threat detection — it requires ransomware resilience.
89%
of security leaders experienced business operations impact from ransomware — and 93% rank downtime as a top concern. *

It doesn't care about your EDR

Ransomware operators think of your EDR as a speedbump, not a roadblock — using valid credentials and legitimate admin tools to bypass it. They don't trigger alerts. They exploit what EDR was never designed to cover.
25%
of organizations actually trust EDR to defend against today's ransomware, despite 98% using it. *

"EDR solutions have not been designed to tune into the specific behaviors and approaches of ransomware attacks... the amount of undetected ransomware calls into question the effectiveness of those solutions."

The Ransomware Experts

A specialized threat demands a specialized defense.

Generic security operations weren't built to fight ransomware — so we built a platform dedicated entirely to stopping ransomware and backed it with the world's first Ransomware Operations Center (ROC).
