We're Pioneering the Anti-Ransomware Engine

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

Halcyon is built by offensive security experts to stop attackers.

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 is a last resort to prevent the spread of ransomware across your company.

Features & Benefits


Modern SOC and MSS teams need products that integrate with their workflows. The Halcyon platform can be deployed and managed entirely via API.

Pre-Execution Defense

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


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 alongside EPP/EDR/XDR without issue.

Resiliency and Isolation

Defense against ransomware is an all-or-nothing game, when ransomware gets by any security product, it results in a catastrophic failure of varying size. Halcyon has recovery, resiliency and automatic isolation to ensure all risk of ransomware is mitigated.

Deception and Anti-Detonation

Ransomware won’t run if it thinks it’s being monitored or running on a system it shouldn’t. Halcyon is the first security product to include deception as a core feature to compliment layers of proactive and reactive defense.

Built for the Enterprise

Halcyon currently offers support for Windows 10 & 11, and Windows Server 2012 R2, 2016, 2019, 2022. Additional Windows support coming soon. MacOS and Linux available soon. Legacy systems supported by request.

Ransomware Protection Without the Expensive Managed Services

Most security vendors that claim to offer ransomware protection only do so with expensive managed service tier offerings. Our anti-ransomware engine works out of the box without an additional services contract.

Enterprise Security Shouldn't Be Difficult

No Services Required + No Conflicts + No Headaches
