Ranking the top Island browser alternatives and competitors in 2026

Island is the best-known enterprise browser on the market. It's the most-reviewed product in Gartner Peer Insights' secure enterprise browser category, and it raised $400 million at a $6.4 billion valuation in September.

But plenty of teams that evaluate Island end up looking elsewhere, usually citing the cost or the need to switch browsers as the main drawbacks. This guide recommends the top alternatives and explains why we left the rest out.

What is the Island browser?

Island started as an enterprise browser company and now calls itself "the control plane for your agentic enterprise," positioning more as a modern SASE vendor. It has three product lines:

• Enterprise Browser: The original product, the Island Enterprise Browser, is a Chromium-based secure browser with zero trust access controls that gives IT control over copy/paste, printing, downloads, screenshots, watermarking, and redaction, plus device posture checks, private app access, and privileged session capture. An

  extension brings a subset of those controls to Chrome, Edge, Firefox, and Safari, and Island Desktop covers macOS and Windows endpoints.

• Enterprise Network: Island's "Modern SASE" bundles SWG, ZTNA, CASB, DLP, RBI, and DEX under one policy engine. Because enforcement happens in the browser and on the device, Island says 90% of sessions go direct, without backhaul or default TLS inspection.

• Enterprise AI: Governance for prompts, outputs, and agentic workflows, plus identity, guardrails, human approvals, and cost controls for AI agents, according to its September funding announcement.

Why teams look for Island alternatives

• Cost structure. Island doesn't publish prices, but UK resellers' public price lists give its list price as $250,000 a year per customer for the management console, plus $200 per user per year. Island's AWS Marketplace listing also starts at $250,000 for a 12-month contract.

• A browser switch. Island's extension brings "core capabilities" to existing browsers, but Island reserves "the deepest set of Island capabilities" for its own browser. Getting the full product means moving people onto a new browser, which can be unpopular and adds friction. Rollouts are usually phased as a result, and the people who haven't moved yet, often Mac users on Safari, developers who prefer Chrome, BYOD users, and teams that resist the switch, sit outside the full product until they do.

• A widening platform. Island's latest funding announcement positions it as a control plane for "browsers, endpoints, networks, and data." That's a large platform to buy if what you need are the core enterprise browser use cases: AI visibility and control, data protection, extension and app governance, and protection from browser-based attacks.

• Day-to-day friction. Reviewers on AWS Marketplace say controls like blocking copy/paste and screen sharing "can become inconvenient, and they end up slowing me down," and that conflicting policies are hard to manage. G2's buyer data puts Island's average implementation time at three months.

• Threat protection. On phishing, Island's knowledge hub guide puts URL enforcement first: Blocking "known categories of phishing" and "newly registered or suspicious domains." Reputation-based blocking stops sites that are already flagged, but Spamhaus has found that 89% of phishing domains are active for less than two days, so most phishing pages are gone before a list catches up.

Island alternatives: Quick picks

The best Island alternatives

1. Push Security: Best Island alternative for most organizations

Push brings enterprise browser controls to the browsers your people already use, from Chrome, Edge, Firefox, and Safari to agentic browsers like Comet and Dia, and even Island itself. Push has gone out to 100,000 users in less than an hour. From one console, it covers:

• AI: Discovers AI apps, AI extensions, and agentic browsers, and blocks AI apps you haven't approved.

• Data: Clipboard rules based on content patterns, plus upload and download blocking by file type, file name, or user group.

• Extensions: Inventory, allowlisting, and removal, with alerts when an extension changes owner or asks for new permissions.

• Apps and web access: Shadow IT discovered from real logins, and web filtering across 80+ domain categories.

• Contractors and BYOD: Self-enrollment without MDM, and your identity provider can require a Push-protected browser before granting access.

Stopping browser-based attacks is where Push moves furthest ahead of Island. Push detects attacker techniques from what a page does in the session, not where it's hosted, so detections keep working after a kit moves to new domains. That stops AiTM phishing, ClickFix, device code phishing and other authorization attacks, and stolen session tokens, almost always before the user is compromised.

Those detections come from Push's agentic threat hunting pipeline. AI agents, steered by the research team that discovered ConsentFix, hunt across telemetry from millions of browsers and ship new detections to every customer automatically. Push's July figures show the results:

• New detections shipped have tripled this year, and the time to ship one has dropped from weeks to minutes.

• The agents run 300+ hunts a month and have documented 75+ attacker tools.

• In the three months to July, Push protected 60+ customers targeted with never-before-seen phishing techniques and stopped 225+ such attacks before compromise.

At $5 per user per month billed annually, with volume discounts above 500 users, 500 seats cost $30,000 a year against $350,000 for a direct Island contract at list price.

Choose something else if: What you mainly need is a VDI replacement for web work or contractor access to private apps, which is where Island is strongest.

2. Prisma Browser (formerly Prisma Access Browser): Best if you're a Palo Alto Networks customer and still want a dedicated browser

Of the dedicated browsers on the market, Prisma Browser is the nearest match to Island. Palo Alto Networks acquired it as Talon and sold it as Prisma Access Browser before the current name. It's a Chromium-based browser with last-mile data controls, and it brings Palo Alto's Advanced WildFire sandboxing, known-bad domain blocking, Precision AI phishing scanning, and Enterprise DLP with more than 1,000 classifiers into the browser. For organizations already running Prisma SASE, one policy plane from network to browser is a real advantage over adding Island alongside it.

It's also cheaper at list price. A UK reseller lists the standalone license at $129 (after conversion) per user per year, with no separate console fee, and Prisma Browser for Business, the small-business edition, is $99 per user per year.

Choose something else if: You don't run Palo Alto's stack, or you need coverage on unmanaged devices without moving people to a new browser. Even the standalone license needs a Strata Logging Service instance and covers internet and cloud access only, with private app access requiring Prisma Access. As for the extension, Palo Alto's admin guide positions it as a stepping stone ("a foundational layer in a phased deployment") on the way to the full browser, and the vendor's FAQ advises against secure extensions on unmanaged devices.

3. Chrome Enterprise Premium or Edge for Business: Best if you've standardized on one browser and only need basic controls

If most of your workforce already uses Chrome or Edge, the browser vendor's own enterprise tier gives you a basic set of controls without a new browser, though far fewer than Island or Push.

Chrome Enterprise Premium costs $6 per user per month and adds real-time DLP, watermarking, screenshot blocking, shadow AI controls, and context-aware access to standard Chrome, including on personal devices through managed Chrome profiles. In practice, the shadow AI controls work by URL category: Admins can block, warn on, or apply DLP rules to sites Google classifies as Generative AI, in Chrome only, and a report on which AI sites are in use was announced in April as coming soon. Push, by comparison, discovers AI tools from real logins, including which account was used, and monitors the OAuth permissions people grant to AI agents, in every browser.

Edge for Business comes with Microsoft 365, integrates with Entra, Purview, Intune, and Defender for Endpoint, and can block downloads, screenshots, and copy/paste to personal devices. Its controls for unmanaged AI tools, though, cover a fixed catalog of 19 app entries, including ChatGPT, Gemini, DeepSeek, and Perplexity, and only on Intune-managed Windows devices, according to Microsoft's Purview documentation. Blocking risky prompts also needs Microsoft 365 E5 plus pay-as-you-go Purview billing, per the Edge security page.

Choose something else if: Your users work in more than one browser, you need AI visibility beyond a list of known sites, or you need detection beyond known-bad sites. Both protect only their own browser.

Alternatives we didn't recommend, and why

These products all come up in Island comparisons. Each is a capable product for its own buyer, but none of them is a better fit than the three above for most teams moving away from Island.

• Sophos Protected Browser. It's powered by Island, so it shares Island's architecture and limits. It makes sense if you're already on Sophos, but it isn't really an alternative.

• Menlo Secure Enterprise Browser. Menlo is strongest at keeping malicious files and exploits off the endpoint, by rendering risky pages in its cloud and rebuilding files before they're downloaded. That's a different job from Island's workspace control, and isolation does much less against attacks that work through the user's own actions inside the page. Rollouts also take a while: G2's buyer data puts the average at five months.

• Citrix Enterprise Browser. Its controls come from Citrix Secure Private Access, so it only makes sense if you already run Citrix Workspace.

• Netskope One Enterprise Browser. It's built for Netskope SSE customers covering contractors and unmanaged devices, and there's very little independent user feedback on it yet.

• SURF Security. SURF offers a Chromium browser and an extension with good GenAI data controls, but it's a much smaller vendor, and its extension only covers Chromium browsers such as Chrome and Edge.

• LayerX (Akamai), Seraphic (CrowdStrike), and Keep Aware (Jamf). These are browser security tools rather than replacements for Island's workspace controls, and all three are now part of larger platforms, so their roadmaps follow their new owners' priorities. We cover them in our browser security solutions list.

How much does the Island browser cost? Island pricing compared

Island doesn't publish per-user pricing, but three UK resellers, Somerford, Bytes, and Softcat, publish the same list price: $250,000 a year per customer for the management console plus $200 per user per year. For a 500-person company, that's a total cost of $350,000 a year before discounts, or about $58 per user per month. Because the console fee is fixed, the per-user cost is highest for smaller deployments. Smaller teams can also buy through managed service providers that run Island for them: Obsidian Ridge lists it at $18 per user per month with no minimum, with AI protection and private app access as paid add-ons. That's still more than three times Push's $5.

For comparison, Push lists at $5 per user per month on an annual plan, or $30,000 a year for 500 users. Prisma Browser's standalone license lists at about $129 per user per year, and its small-business edition at $99. Chrome Enterprise Premium is $6 per user per month, and Edge for Business comes with Microsoft 365, with GenAI prompt protection needing E5, which lists at $60 per user per month against $39 for E3. These are list prices before negotiation, and Island's price list notes that volume discounts are available.
