Company Overview

Fireglass developed remote browser isolation technology to separate users from active web threats, reducing exposure to phishing, exploit kits, and malicious content. The model became a key architectural approach for high-risk browsing environments.

The company was Israel-founded, venture-backed, and later acquired by Symantec. Its technical approach helped establish browser isolation as a practical cyber-defense control in enterprise and regulated sectors.

Dual-use relevance is clear: isolation-based browsing safeguards can protect both private-sector operations and government/defense-adjacent organizations handling sensitive workflows online.
