Enterprise browser startup Island has secured a massive $250 million Series E funding round, pushing its valuation close to $5 billion. This latest investment, led by Coatue Management, reflects strong investor confidence in the security browser space, even as tech giants like Microsoft and Google intensify competition.
With this new round, Island’s total funding now stands at around $730 million since its launch in 2020. Headquartered in both Texas and Israel, the startup is positioning its enterprise-grade browser as a secure alternative to traditional consumer browsers frequently targeted by cyber threats.
Island’s CEO, Mike Fey, emphasized the growing demand for a dedicated enterprise browser that blends productivity with robust security controls. According to Fey, Island’s solution serves as a critical piece in modern IT infrastructure, providing organizations with the tools to streamline workflows while enhancing cybersecurity.
Fey noted:
“The Enterprise Browser transforms a basic web browser into a powerful business tool. It drives productivity, simplifies IT operations, reduces complexity, and embeds security at the core. Our technology offers granular control over sensitive actions like copy, paste, download, and upload while enabling features like data redaction, watermarking, and integrated multi-factor authentication.”
The company plans to use the fresh capital to accelerate product development and expand its workforce. Currently, Island employs around 500 people, with over 200 dedicated to engineering and product innovation.
Since coming out of stealth mode in February 2022, Island has rapidly grown its customer base to over 450 companies across multiple sectors. These range from Fortune 1000 enterprises and mid-sized firms to government agencies and academic institutions—all seeking better control over browser-based security threats.
Island’s rise coincides with major moves from industry leaders like Microsoft, which recently introduced Microsoft Edge for Business. This new version of Edge creates distinct environments for personal and professional browsing, with separate caches, favorites, and storage settings aimed at boosting security.
Meanwhile, Google continues to pitch its enterprise-focused Chrome offering, designed to protect organizations from web-based attacks while simplifying browser management.
Island’s impressive growth and investor backing underscore the increasing importance of secure enterprise browsers as companies face mounting cybersecurity threats. The Series E funding positions Island to scale further and compete head-to-head with Big Tech players in this fast-evolving market.
