Best for anonymous web research for investigators
Silo Workspace is a cloud investigation environment where analysts research the web through isolated workspaces and the vendor's own network of endpoints. It costs $1,450 to $3,450 per user a year by regions covered, and Authentic8 says it does not replace everyday browsing.
Who Authentic8 Silo is for
- 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
Who Authentic8 Silo is not for
- 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
Why Authentic8 Silo gets a 1.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- DValue for money$1,450 to $3,450 per user a year, which is about $121 to $288 a month, far above this category's $21 dearest-tenth line. Its rivals publish no prices to set against.
- DFree plan and trialA 30-day trial with limited egress nodes is listed, but the listing does not say whether it needs a card, so it is graded as one that might.
- CFeaturesIsolated workspaces, a managed attribution network and audit, but Nexus AI is capped at 10 prompts a day on these tiers.
- CEase of useNo rating on record. It is a cloud environment where analysts set up regions and workspaces, with a learning curve.
- CPlatforms and integrationsA cloud environment reached from the web. The pages do not list client operating systems, though Telegram, Signal and Maltego run inside.

Keep Authentic8 Silo, or make your own?
Keep it
To replace Authentic8 Silo you would be making a web browser. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 58 of the 60 other browsers grade higher. It costs $1,450 a year.
What you could not
- A web browser.
- A library of papers and sources to search.
- It is priced for each person, which means accounts and billing for a team.
- It plugs into other products, Telegram, Signal and Maltego among them.
- AI features, unless you pay a model provider for each request yourself.
- What a company asks for before it lets staff use something: audit logs.
What this rests on. Authentic8 Silo’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Authentic8 Silo?
Silo Workspace from Authentic8 is a cloud-based investigation environment built around the Silo for Research browser. Analysts open isolated workspaces that route traffic through the vendor's own network of regional endpoints, so web research does not touch their own systems or reveal their identity. It is priced per user per year by how many regions are covered.
Worth knowing
- 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.
Key features
- 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.
