Island, the enterprise browser company, has raised $250 million in Series E funding, elevating its valuation to almost $5 billion. The financing round was led by Coatue, with participation from existing investors. To date, the company has secured $730 million in total funding, with previous rounds including a $175 million raise in 2024 at a valuation of $3 billion.
The new capital infusion will be directed towards product development, team expansion, and accelerating market adoption. Island’s goal is to solidify its leadership in the enterprise browser security space by expanding its solution set and increasing enterprise penetration across industries.
Visionaries behind Island
Island was co-founded by Mike Fey, former CEO of Symantec, and Dan Amiga, a renowned Israeli serial entrepreneur in 2020. Fey brings deep cybersecurity expertise, while Amiga’s technical prowess drives innovation within the company’s architecture. Its workforce has expanded to 500 employees, with over 200 engineers dedicated to product development and innovation.
The team operates across key locations, with its development hub in Tel Aviv and headquarters in Dallas, Texas. Both founders are also Limited Partners (LPs) in Cyberstarts, an early investor in Wiz, and stand to benefit financially from Google’s recent acquisition of Wiz, underscoring their successful track record in cybersecurity.
The Island Enterprise Browser: Transforming security and productivity
Island’s Enterprise Browser serves as a secure, seamless workspace that embeds IT, security, and productivity needs directly into the browser. Designed to empower organisations with unprecedented last-mile control, the browser gives IT and security teams complete visibility while ensuring a native, frictionless experience for end users.
The browser company has developed a communications technology that enables fast remote connection to corporate computers as well as internal corporate communications applications and is seeking to expand the scope to other areas with the aim of keeping employees on their browsers as much as possible and bringing corporate customers to increase their browser usage.
The company calls its Enterprise Browser the “desktop of the future”, empowering organisations to protect users and data and embed productivity features.
It is touted to be the world’s first self-protecting browser. This mode secures the browser through advanced measures, including memory, process, and file exploitation protection, encryption of browser resources, and prevention of network-based attacks such as man-in-the-middle exploits. It thwarts keystroke loggers by feeding false data, blocks screen capture attempts, ensures device integrity, and reduces attack surfaces by disabling critical JavaScript APIs. It also governs browser extension usage, enforces hardened policies on developer tools and settings, and protects users through anti-phishing, URL categorisation, and malware inspection.
A native experience for hybrid workforces
The browser delivers a native user experience for hybrid workers at a fraction of the cost of traditional VDI solutions. Built-in capabilities like web filtering, exploit prevention, and safe browsing enable hybrid workers to remain secure and productive. Organisations can also automate repetitive tasks and create customised workflows, driving improved productivity.
Island is well-positioned to lead the emerging enterprise browser security space, where it competes with other Israeli-founded companies such as Talon Security (acquired by Palo Alto Networks for $625 million) and Guardio, which has its own browser.
While the company began its activities by selling a secure browser to large companies, it expanded to other users to encourage company employees to work from its browser rather than Google’s Chrome browser or Microsoft’s Edge.
What lies ahead?
The company’s vision is to redefine how organisations secure and govern enterprise applications by turning the browser into the “desktop of the future.” As more enterprises migrate to cloud-based applications and hybrid work environments, the demand for secure, high-performance browser experiences will continue to rise.
“The Enterprise Browser upgrades web browsers from a dedicated consumer software package to an enterprise-ready solution, adding value to knowledge workers, IT departments, and security teams. Island improves productivity, simplifies the IT stack, reduces complexity, and embeds security,” said Mike Fey, CEO and Co-founder of Island. “Organisations of all sizes and industries have made Island the cornerstone of their IT modernisation initiatives. The new funding will help scale our product development and talent acquisition to meet enterprises’ demanding and evolving IT needs.”
“Customer collaboration has been the key to building the Enterprise Browser since day one,” said Dan Amiga, CTO and Co-founder of Island. “Creating and growing a new category requires deep technical partnerships and maximum trust between CIOs, CISOs, and product teams. Our customers’ input has been invaluable to securing their sensitive data, eliminating IT inefficiencies, and making IT work best for end users.”
“We’re thrilled to continue our partnership with Island as they scale their vision and bring greater security and productivity to the modern workplace,” said David Schneider, General Partner at Coatue. “Island’s world-class executive team has continued to deliver a product that drives immense value for enterprise executives and end users alike. As AI adoption continues to accelerate, Island is helping establish a new industry standard. Companies of all sizes should now rely on secure environments like Island to remain competitive and protect their operations. We look forward to supporting their next stage of growth.”
