Overview

Island makes a web browser designed for businesses. It looks and works much like Google Chrome, because it's built on the same open-source Chromium foundation, but it adds security and IT controls directly into the browser. Companies can decide which websites and apps employees can use, prevent copying or downloading sensitive data, mask confidential fields, record activity for compliance, and give contractors secure access to company apps from their own laptops without installing complicated software. Island has also positioned the browser as a control point for how employees and AI agents use AI tools.

Mike Fey, the CEO, and Dan Amiga, the CTO, founded Island in 2020. Fey was previously president and chief operating officer of Symantec and CTO of McAfee; Amiga co-founded Fireglass, a browser isolation company acquired by Symantec. Island is headquartered in Dallas, Texas, with a large research and development team in Israel.

Why a browser?

Most work now happens in a browser: email, documents, CRM, HR systems, finance tools and AI assistants are all web apps. Traditional security tools sit around the edges, on the network, on devices or in separate gateways, which can be complex and slow. Island's argument is that the browser is where users actually interact with data, so it's the natural place to apply security policies. Controlling the "last mile" lets companies protect data without routing all traffic through other systems.

Use cases

• Contractors and outsourcing: giving third parties secure access to specific apps from unmanaged devices.
• Call centres and frontline staff: locking down what workers can see and copy.
• Replacing virtual desktops: delivering secure access without expensive virtual desktop infrastructure.
• Data loss prevention: stopping sensitive data being copied into personal accounts or unapproved AI tools.
• Productivity: automating workflows and simplifying logins across many apps.

Business model

Island sells annual subscriptions, usually priced per user, to enterprises. Customers include large banks, healthcare organisations, retailers and government agencies. Because it can replace or reduce spending on other tools, such as virtual desktops and some network security products, Island often pitches cost savings alongside security. It doesn't publish revenue; the company says annual recurring revenue has doubled every fiscal year since its 2022 launch. One report estimated ARR around US$200 million in 2026, which we haven't been able to verify.

Funding

Island has raised money quickly at rising valuations, reaching about US$3 billion in 2024 and about US$4.8 billion in 2025. In September 2026 it raised a US$400 million Series F at US$6.4 billion, led by Evolution Equity Partners, with Sequoia, Coatue, Insight Partners and J.P. Morgan Growth Equity Partners. It said it would use the money for product development and go-to-market expansion, including hiring about 500 more people by mid-2027.

Competition

Island competes with browser makers adding enterprise features, notably Google's Chrome Enterprise Premium and Microsoft Edge for Business, with secure access and browser isolation vendors such as Zscaler and Menlo Security, and with Palo Alto Networks, which acquired enterprise browser company Talon in 2023. Its advantages are its head start as a dedicated enterprise browser, enterprise customer base and rich policy controls. Its main risk is that Google and Microsoft give similar features away with their browsers.

Island at a glance

Island is a Dallas enterprise browser company founded in 2020 by Mike Fey and Dan Amiga. It says its ARR has doubled every fiscal year since its 2022 launch. It raised a US$400 million Series F at a US$6.4 billion valuation in September 2026, led by Evolution Equity Partners, more than double its 2024 valuation.

Browsers and AI agents

As AI agents increasingly carry out tasks in web applications on behalf of employees, companies need ways to control what those agents can access and do. Island argues that the enterprise browser can govern both human and AI activity in the same place, for example limiting which internal apps an AI agent can use, or preventing sensitive data being pasted into external AI tools. That positioning around AI governance was a central theme of its 2026 funding.

Total cost considerations

Companies evaluating an enterprise browser often focus on what it can replace. Virtual desktop infrastructure, used to give contractors and remote workers controlled access, is expensive to license and run, and frustrating for users. If a browser can deliver similar control at lower cost and with a better experience, the savings can fund the purchase. The full picture includes migration effort, user training and the risk of running two browsers side by side during the transition.

Questions to ask before deploying

• Which current tools could it replace, and what savings would result?
• How will employees react to using a different browser?
• How does it handle personal browsing on company devices?
• What happens if Google or Microsoft add similar controls to their browsers?

A pilot with a single department, such as contractors or a call centre, usually shows quickly whether users accept the browser and how much cost it can remove. Early feedback from those users is the best guide to a wider rollout across the rest of the company and its partners.

Next steps to watch

Watch ARR disclosures, large enterprise rollouts, AI agent governance features, competition from Chrome and Edge, and any IPO plans.

Practical notes

IT and security teams can use enterprise browsers to secure contractors and reduce virtual desktop costs. Founders can learn from how Island reframed a familiar product as a security platform. Investors should weigh fast growth against competition from the biggest browser makers. Data security company Cyera shares Island's lead investor.
