Island Enterprise Browser vs Menlo Security (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 Menlo Security if

• Fits if your company wants browser protection added to the browsers staff already use
• Makes sense if you have higher-risk users who need cloud-based protection

Look elsewhere if

• Skip it if you want a posted price: only a budget estimate and a sales quote exist
• Not for you if you want something free to try, as no plan or trial is listed
• Pricey if you add features: HEAT Shield AI and file sanitization cost extra
• Watch out: Protect, Secure and Manage are priced separately
• Too heavy for one person: it is sold to organizations by user license

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.

Menlo Security

• No prices are published: Menlo quotes by the products deployed and the number of user licenses.
• A self-service pricing tool gives a budget estimate, and a custom quote comes through sales.
• Products such as Protect, Secure and Manage are priced separately, and add-ons like HEAT Shield AI and file sanitization cost extra.

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.

Menlo Security

Hybrid architecture

Menlo says it combines local in-browser controls with cloud-based protection, and admins can send high-risk locations or users to cloud-based protection.

Menlo IRIS extension

A browser extension adds data and file security, web governance and an inventory of installed extensions with risk scores to browsers already in use.

Add-on threat protection

Add-ons cover zero-day phishing protection (HEAT Shield AI) and file sanitization through content disarm and reconstruction.

AI agent security

The platform applies policies to AI agents browsing the web alongside human users and helps agents reach web applications that lack APIs.

Secure enterprise browser

Menlo lists a secure enterprise browser, remote browser isolation and secure extension among its products.
