Our Mission

Make Ransomware History

Modern defensive cyber solutions, while impressive, have failed in the face of cheap and easy-to-create – and most importantly lucrative – ransomware. High-profile breaches are disguising an ugly fact; the companies using next-generation NGAV and EPP solutions continue to be impacted by ransomware.

Halcyon has built the first anti-ransomware engine to tackle this problem. Our team has spent decades building name-brand security products and delivering security consulting to much of the Fortune 500.

BACKED BY THE BEST

Our Origin Story

Halcyon formed in 2021 by a team of cybersecurity industry veterans after battling the scourge of ransomware (and advanced threats) for years, at some of the largest global security vendors.

Comprised of leaders from Boldend, Cylance (now Blackberry), Accuvant (now Optiv), and ISS X-Force (now IBM), Halcyon is focused on building products and solutions for mid-market and enterprise customers.

While technically headquartered in Austin, TX and San Diego, CA we are unified by our globally distributed, 100% remote, workforce and our mission.
