We're Pioneering Ransomware Resilience

Halcyon is the industry’s first ransomware resilience platform that combines multiple advanced prevention engines along with AI models focused specifically on stopping ransomware.

Halcyon is built by offensive security experts to stop attackers cold.

Here's How It Works

Ransomware protection requires multiple layers of defense; the risk of letting ransomware run rampant through an organization is too large to leave to a single AI or behavioral model. Halcyon uses several unique layers to stop the process of ransomware from completing its task. If a single layer fails Halcyon is able to respond accordingly. Even the best defenses can be breached by a persistent actor which is why Halcyon designed an autonomous isolation and recovery layer as a last resort to prevent the spread of ransomware across your company.

AI Prevention

Halcyon is built exclusively to combat targeted ransomware before it can execute, by using industry-first applications of next-generation machine learning trained solely on ransomware and enhanced by CapsNets.


Security teams use countless products for triage, management and defense. Halcyon is designed to be conflict-free from the outset allowing your organization to deploy it alongside other security tools without issue.

Reduce Downtime 90%

With the average ransomware incident taking 21 days to recovery, each minute spent on triage, recovery from backups and rebuilding critical systems means lost revenue. With Halcyon's ability to restore at the system level, we get you back up and running in a fraction of the time it takes traditional IR efforts.

Data Exfiltration Prevention

It's not just about encrypting data, attackers attempt to pull as much sensitive info off the network as possible. With the Halcyon DXP engine, mass data extortion is a thing of the past.

Built for All Sizes

Whether you have 100 or 100,000 endpoints, Halcyon's ransomware protection is right for you. Halcyon offers support for Windows 10 & 11, and Windows Server 2012 R2, 2016, 2019, 2022. RedHat Linux available in 2H 2024.

Ransomware Protection
Without Compromise

Most security vendors that claim to offer ransomware protection only do so with expensive managed service tier offerings or by hardening backups. Our anti-ransomware engine works out of the box without an additional support contracts to make it work.
