Authentic8 Silo vs Island Enterprise Browser (2026): which should you pick?

Pick Authentic8 Silo if

• Fits if you investigate sites and need your own systems kept out of it
• Makes sense if you need research traffic to come from chosen regions

Look elsewhere if

• Pricey if you are one person: the lowest tier is $1,450 per user a year for one region
• Skip it if you want everyday browsing: Authentic8 says it is not a VPN, VDI or enterprise browser
• Tight if you need AI: Nexus AI is capped at 10 prompts a day on the listed tiers
• Watch out: the price rises with regions, to $3,450 for all of them
• Watch out: the trial has limited egress nodes

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

Authentic8 Silo

• Pricing is per user per year, and the price rises with the number of regions covered.
• Nexus AI is capped at 10 prompts a day on the listed tiers; unlimited use is an enterprise option.
• Authentic8 says it is not a VPN, VDI or enterprise browser, so it does not replace everyday browsing.
• The pages read do not list client operating systems; Silo is described as a cloud environment.

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.

Authentic8 Silo

Isolated workspaces

Each workspace runs apps in separate containers away from the user's network, so content from the threat space cannot reach local systems.

Managed attribution network

Traffic exits through 700+ endpoints across 100+ regions, with residential, mobile, data center, Tor and dark web options.

Apps beside the browser

Workspaces combine the Silo for Research browser with apps such as Telegram, Signal, Maltego, LibreOffice and Obsidian.

Governance and audit

Admins enforce access, data and usage policies, watch activity in real time and keep encrypted audit logs.

Nexus AI

An AI assistant with source-grounded responses and live content capture is included, limited to 10 prompts a day on listed plans.

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.
