Island Enterprise Browser vs Kasm Workspaces (2026): which should you pick?

Pick Island Enterprise Browser if

• Fits if your IT team wants browser rules over copy, print and download
• Makes sense if you want one policy set on laptops and phones

Look elsewhere if

• Skip it if you need a price before talking to sales, as none is published
• Not for you if you work alone, since it is sold to organizations
• Watch out: there is no free plan or trial listed, only a demo
• Watch out: the extension supports most but not all of the full browser's capabilities
• Tight if you cannot get a login: the download requires being an existing Island user

Pick Kasm Workspaces if

• Fits if you want isolated browsers for your own non-commercial use
• Makes sense if your team already runs Docker or Kubernetes servers

Look elsewhere if

• Skip it if you want a price list, since paid editions are contact-sales
• Not for you if you use it commercially on the free tier: Community is for individuals, nonprofits and non-commercial use
• Tight if you need more than 5 concurrent sessions on Community
• Watch out: paid editions require a standard support subscription
• Too heavy if you do not run servers: self-hosting means installing on a Linux server you run

Island Enterprise Browser

• No prices are published: the site offers a demo and a quote request, and its /pricing page returns an error.
• Aimed at organizations; the download requires logging in as an existing Island user.
• The extension supports most but not all of the full browser's capabilities because extensions have restrictions.

Kasm Workspaces

• No prices are published for the paid editions; Basic, Essentials and Premier are contact-sales.
• Community Edition is limited to 5 concurrent sessions and to individual, nonprofit or non-commercial use.
• Paid editions need a support subscription: the feature matrix marks standard support as required.
• Self-hosting means installing on a Linux server you run.

Island Enterprise Browser

Conditional application access

Admins set access rules that check identity, device, network, location and application, enforced inside the browser.

Data controls

Policies govern print, downloads, screenshots and copy/paste, including after data leaves the browser, to limit leakage between apps.

Activity visibility

Work activity is logged and can be shared with a SIEM, while a privacy indicator tells users when they are monitored and personal browsing stays private.

Web threat protection

The browser includes protections against malware, phishing and session hijacking, per Island's product page.

Extension option

A browser extension covers most of the full browser's capabilities on Chrome, Edge, Safari, Firefox and other Chromium-based browsers.

Built-in productivity tools

Users get an AI assistant, a smart clipboard, an ad and tracker blocker and a geolocation anonymizer, according to Island.

Kasm Workspaces

Browser isolation

Web isolation workspaces run browsing in a container away from the endpoint, with web content filtering.

Desktops and apps

Streams Linux desktops, Windows desktops and individual applications to the browser, with no client install needed.

Workspace images

A library of images including Chrome, Firefox, Brave, Edge, Chromium and Vivaldi browsers, development tools and OSINT tools.

Admin controls

User groups, single sign-on, two-factor authentication, DLP controls and an admin console with session history.

Flexible hosting

Single-server, multi-server and Kubernetes deployments, or hosted by Kasm in the cloud.
