Company History and Business Evolution

Menlo Security was founded in 2013 by security veterans Amir Ben-Amram, Kowsik Guruswamy, and Poornima DeBolle, who recognized that traditional web security measures were failing against advanced threats. The company pioneered the concept of ‘isolation’ – processing all web traffic in a remote container to prevent malware from reaching endpoints. This innovation quickly gained traction, leading to Series A funding from Sutter Hill Ventures and subsequent rounds from General Catalyst, American Express Ventures, and others. In 2016, Menlo Security launched its Cloud Security Platform, integrating RBI with a secure web gateway. The company expanded into the UK market in 2018, opening a London office to serve European customers. Over the years, Menlo Security has achieved significant milestones: surpassing 1,000 enterprise customers, processing over 10 billion web requests monthly, and earning accolades such as ‘Best Security Solution’ at the SC Awards. In 2021, the company introduced its Zero-Trust Browser, extending isolation to SaaS applications. In 2023, Menlo Security UK partnered with major UK telecom providers to offer managed security services. The company continues to evolve, focusing on AI-driven threat detection and seamless integration with existing security stacks. This growth trajectory underscores Menlo Security UK’s commitment to staying ahead of cybercriminals and providing robust defense mechanisms for modern enterprises.
