Menlo Security provides enterprise browser security solutions designed to protect organizations from internet-borne attacks and data leakage. The company's core offering is the Secure Enterprise Browser, which works with existing local browsers to manage browser attack surfaces, deploy security policies, and provide forensics capabilities. The solution includes category-based filtering, keyword filtering, and URL filtering to block access to harmful content and problematic websites. The platform operates as a cloud service that enables organizations to secure web sessions while allowing users to maintain their preferred browsers. Menlo Security's approach includes browser security policies, monitoring and reporting through Menlo Browsing Forensics, and circumvention prevention measures to block proxy servers and VPNs used for malicious purposes. The solution supports compliance requirements such as CIPA (Children's Internet Protection Act) through customizable content filtering and policy enforcement. The company serves enterprises and government organizations worldwide, with particular adoption among large financial institutions. Founded by veterans from Check Point Software, Juniper Networks, and Altor Networks, Menlo Security positions itself as a pioneer in browser security, addressing the browser as both an entry point for attacks and an exit point for data leakage. The platform provides centralized updates and management capabilities for distributed workforces accessing applications through web browsers.
