What we do:
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.
Who we are:
Halcyon was formed in 2021 by a team of cyber 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 Cylance (now Blackberry), Accuvant (now Optiv), Fireye and ISS X-Force (now IBM), Halcyon is focused on building products and solutions for mid-market and enterprise customers.
As a remote-native, completely distributed global team, we recognize great talent can exist anywhere. We invite you to apply to a job you’re interested in and we’ll work a plan to meet your needs.
Halcyon’s goal is to deliver an anti-ransomware solution that breaks new ground in what a security product can achieve. Aligned with this vision, we are seeking an experienced engineer to contribute to the development of our macOS agent. This agent combines macOS extensions with a user-level service written in Rust, C++, and Swift. By expanding platform support, we are ensuring our customers are further protected from ransomware threats. If you’re passionate about macOS security and want to make a real difference, we’d love to hear from you.
