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.

Halcyon is seeking a highly skilled and experienced Senior Technical Support Engineer to join our growing support team.
