Cylance was founded in 2012 in Irvine, California, focusing on using artificial intelligence to prevent cybersecurity threats proactively. While their early success was rooted in enterprise solutions, they expanded into the consumer space in 2018 with Cylance Smart Antivirus—a lightweight, AI-based security tool designed to stop threats before they could run.

Users could manage multiple devices through a centralized, cloud-based dashboard.
