Isolated Browsing: Silo Workspace or Octo Browser?
Choosing silo workspace vs octo browser for isolated browsing means picking between two different products, not two tiers of one. Silo Workspace is Authentic8’s cloud investigation environment: sessions run in ephemeral containers and stream to your device, licensed per user per year. Octo Browser is a local browser profile manager: each profile holds its own cookies, storage and settings on your machine. Your workflow — evidence handling or many owned accounts — decides which one fits.
📌 TL;DR Executive Summary
- Core Takeaway: Silo Workspace streams investigation sessions from isolated cloud containers; Octo Browser isolates local profiles on your own machine. They solve different problems, so workflow fit beats a feature score.
- Key Risk/Challenge: Silo is internet-dependent, quote-priced per user per year, and some sites may still detect managed browsing environments. Octo leaves RAM, disk, backups and local data hygiene to you, and its docs warn that VPN-plus-proxy setups reduce speed.
- Recommended Solution: Choose Silo for evidence work with audit trails, Octo for many owned accounts on one workstation. Teams sharing owned client accounts across devices get isolated profiles, residential proxies and cloud sync with Send.win from $19/mo.
The table below is the short version; each section after it goes deeper on architecture, networks, pricing and data retention.
| Silo Workspace (Authentic8) | Octo Browser | Send.win | |
|---|---|---|---|
| What it is | Cloud investigation environment: Silo for Research browser plus apps such as Telegram, Signal and Maltego | Local browser profile manager | Desktop and cloud browser profile manager |
| Where sessions run | Isolated, ephemeral cloud containers streamed to your device | On your own machine, one profile per identity | Native desktop app, or cloud browser hosted in Helsinki, Finland |
| Isolation unit | Session and workspace, destroyed or deprovisioned at the end | Browser profile with its own proxy, tags and storage toggles | Browser profile with its own cookies, storage, fingerprint settings and proxy |
| Best fit | OSINT, security and investigation teams | Individuals or teams running many owned accounts locally | Agencies, sellers, social media and QA teams sharing owned accounts |
| Pricing model | Per user, per year; tiers differ by regional network coverage | Subscription; price not published in the vendor docs reviewed | Pro $19/mo or $83.88/yr; Team $49/mo or $251.88/yr |
Architecture: Cloud Isolation vs a Local Profile Manager
Architecture is the first fork in silo workspace vs octo browser for isolated browsing: one runs all web code in a remote cloud, the other runs it on your own hardware. Silo Workspace runs web code somewhere else. Remote browser isolation with pixel streaming renders all web code in the remote cloud and sends you an interactive stream; a DOM-mirroring approach instead lets some code render on your device. Authentic8 delivers Silo as a cloud browser-as-a-service, with sessions in isolated, ephemeral containers destroyed at session end and private or hybrid deployments available for residency or compliance needs. Cookies, ETags and temporary files stay in the remote browser’s cloud rather than accumulating on your endpoint.
What a Silo workspace holds
A workspace can combine the Silo for Research browser with applications such as Telegram, Signal, Maltego, LibreOffice and Obsidian, and workspaces launch in seconds. Browsing data, credentials and app state persist across sessions, and you can run unlimited workspace configurations. When an investigation closes, deprovisioning preserves or erases that state with no cross-contamination. For the underlying mechanics of session separation, see our guide to isolated browsing, and Authentic8’s own Silo Workspace product page for the vendor’s current feature set.
What an Octo Browser profile holds
Octo installs locally and isolates at the profile level. Its documentation lists what you configure per profile: icon (up to 20), name, template, folder, description, proxy or VPN, tags, start pages (maximum 20), bookmarks (maximum 100) and cloud storage toggles for cookies, passwords, extensions, local storage, history, bookmarks and service workers. Bulk creation and templates build a batch of similar profiles quickly. Nothing streams, so there is no extra hop — but the RAM, disk space and local cleanup are yours to manage.
Identity, Fingerprints and What Sites Actually See
Identity is the second fork in silo workspace vs octo browser for isolated browsing, because each product separates accounts at a different layer. Silo separates identity at the network layer. Traffic routes through 700+ in-region nodes across all continents, using residential, mobile, data center and dark web connection types, and nodes can be shared or reserved privately for one mission. You choose the regional egress point and can change the browser’s web agent. Authentic8’s own OSINT guidance notes that changing the web agent matters and that extra layers may be needed beyond the cloud provider’s IP.
Octo Browser separates identity at the profile layer. Its documentation recommends against changing the default user agent and says to keep the Chrome version the product ships, because manually changed parameters can compromise profile integrity. Fewer knobs to break, less freedom if a site expects something specific.
Send.win keeps a consistent fingerprint per profile — canvas, WebGL, audio, fonts and hardware characteristics — handled inside the browser engine, so profiles do not share one browser identity. That is per-profile privacy protection in the same spirit as the fingerprinting protection in Firefox or Brave, and it says nothing about how a given site will treat you. Where that fingerprint lives when a profile runs in the cloud is covered in our guide to how cloud browsing works.
None of the three makes a session invisible. Directory listings such as the OSINT Tools Library entry for Silo state that some websites may still detect automated or managed browsing environments, and that platforms may restrict certain target sites. Treat vendor language such as “non-attributable” as positioning, and check each site’s rules before you start.
Network and Proxy Options Compared
Silo bundles the network into the licence: you do not buy proxies separately, and regional coverage of the Silo network is the one thing that changes between tiers. Octo is proxy-agnostic — HTTP, HTTPS, SOCKS5 or SSH, plus WireGuard and AmneziaWG VPNs — and its docs warn that running a VPN and a proxy together reduces speed and usability.
| Network capability | Silo Workspace | Octo Browser | Send.win |
|---|---|---|---|
| Proxy support | Network included; residential, mobile, data center and dark web connection types | HTTP, HTTPS, SOCKS5 and SSH; WireGuard and AmneziaWG VPNs | Residential proxies included on Pro and Team, plus bring-your-own HTTP/SOCKS5 |
| Egress locations | 700+ in-region nodes across all continents, with private nodes for one mission | Whichever endpoint your proxy or VPN provider supplies | Whichever endpoint your proxy supplies; residential bandwidth is metered |
| Identity alignment | You select the regional egress point and can change the browser’s web agent | Proxy and VPN settings live in the profile configuration | Timezone, locale, WebRTC and geolocation follow the proxy’s exit IP automatically |
Bandwidth economics differ as well. A Silo licence folds network use into a per-user fee, so a heavy research month does not create a separate proxy bill. Octo and Send.win keep that cost visible: you pay your own provider or use included residential bandwidth and top it up. Send.win includes 5 GB a month on Pro and 20 GB on Team, with extra bandwidth at $6 per GB and extra profiles at $0.05 each. Our Octo Browser review covers how its plans are structured.
Pricing: Annual Per-User Licences vs Monthly Subscriptions
Pricing is the third fork in silo workspace vs octo browser for isolated browsing, and it is the least comparable: one product is billed per user per year, the other as a subscription. Silo Workspace is priced per user, per year. Every tier includes the full platform — features, productivity tools and Silo Nexus AI — and tiers differ only in regional coverage of the Silo network: one region, two regions, or all of them across North America, Europe, Central and South America, Asia-Pacific, Africa and the Middle East, plus Dark Web and Rapid Response Nodes. The pricing pages reviewed here list no dollar figure, so treat Silo as a quote-based annual purchase.
One cap matters before you lean on the AI features: Nexus AI allows up to 10 prompts per day on the standard tiers, with enterprise options for unlimited use. You are buying geography and egress reach, not extra seats or workspaces.
Octo Browser’s documentation does not publish prices or trial terms, so confirm them on the vendor’s page before budgeting. What the docs do state is that profiles are not deleted automatically and remain stored for 6 months after a subscription expires. Our breakdown of Octo Browser pricing covers how subscription tiers usually map to profile and storage limits.
| Tool | How it is billed | Published price | What changes between tiers |
|---|---|---|---|
| Silo Workspace | Per user, per year | Quote-based; no list price on the pricing pages reviewed | Regional coverage: one, two or all network regions |
| Octo Browser | Subscription, per the vendor’s current plans | Not published in the vendor docs reviewed here | Profile and storage limits on the vendor’s current page |
| Send.win | Monthly or annual | Pro $19/mo or $83.88/yr ($6.99/mo); Team $49/mo or $251.88/yr ($20.99/mo) | Profiles 150 to 500, bandwidth 5 GB to 20 GB, seats 6 to 16, cloud sync 20 to 100 profiles |
Send.win is the simplest of the three to price: Pro gives you 150 saved profiles, 5 GB of residential proxy bandwidth a month and 6 seats; Team gives you 500 profiles, 20 GB and 16 seats. Both allow up to 50 profiles open at once, cover the desktop app and the cloud browser, and the first card purchase carries a 7-day money-back guarantee.
Market context helps frame the spread. Research cited in a 2026 roundup values browser isolation at $2.03 billion in 2025, forecast to grow at a 24.74% CAGR through 2031, with cloud deployments above 60% of revenue. Kasm Workspaces lists self-hosted tiers from $10 per user, and Parallels Browser Isolation starts from $19 a month on an annual plan. Silo’s enterprise licensing and Send.win’s entry price sit at opposite ends of that range.

Which Should You Pick?
After the architecture, identity and pricing sections above, the silo workspace vs octo browser for isolated browsing choice usually reduces to three questions: where the session data must live, who hands work to whom, and whether policy has to be central. Here is how that plays out case by case.
Pick Silo Workspace if…
Your work is investigation, research or evidence collection, you need session data to disappear cleanly at the end, and you want policy controls, session recording and audit trails. A per-user annual licence with regional tiers suits a team that already carries a security or compliance budget — but test latency from your real network first.
Pick Octo Browser if…
You run many accounts you own from one workstation, you already trust a proxy provider, and you want granular per-profile control without paying for cloud infrastructure. It fits cases where local speed matters more than central policy or handing a profile to a teammate.
Pick Send.win if…
You are an agency, seller, social media team or QA group working with accounts you own or are authorised to manage, and handover is the recurring problem. Shared profiles open already signed in, cloud sync carries logins across devices, and public pricing means no sales call: $19 a month for Pro, $49 for Team.
Rules that apply to all three
Use these tools only with accounts you own or are authorised to manage, and follow each platform’s terms. Where a platform limits multiple accounts — Amazon requires approval for an additional seller account, and agencies on Meta work through Business Manager roles — take that official route. A restricted or banned account is resolved through the platform’s own appeal or verification process.
Persistence, Retention and Handover
Silo persists browsing data, credentials and app state across sessions, with unlimited workspace configurations; deprovisioning when a case closes preserves or erases that state without cross-contamination. Individual sessions stay disposable — containers, cookies, ETags and temporary files die at session end — while policy controls and audit trails keep their own retention windows. For evidence work that split is the point: durable case data, single-use session data.
Octo Browser stores profiles for 6 months after a subscription expires instead of deleting them, and cloud storage toggles decide which data categories are kept. Send.win keeps local profiles on your machine and syncs logins across devices — 20 profiles on Pro, 100 on Team — with 1 GB of encrypted cloud storage on Pro and 15 GB on Team. Before any licence ends, export what you need and confirm what the vendor retains.
🏆 Send.win Verdict
Silo Workspace wins when the job is an investigation and you need streamed cloud sessions with policy controls and audit trails. Octo Browser wins when you want granular local profiles and already have proxies you trust. Send.win covers the everyday case this comparison usually skips: teams running accounts they own or are authorised to manage — client profiles, storefronts, ad accounts, QA test users. It runs as a desktop app or a cloud browser, gives every profile its own fingerprint protection, cookies, storage and proxy, includes residential bandwidth, and lets a paid teammate open a shared profile already signed in instead of passing passwords around.

Frequently Asked Questions
Which is better for isolated browsing: Silo Workspace or Octo Browser?
The silo workspace vs octo browser for isolated browsing question has no single winner, because they isolate different things. Silo isolates streamed cloud sessions for investigation work, with ephemeral containers, network-level attribution controls and audit trails. Octo isolates local browser profiles for people running many owned accounts on one machine. Match the architecture to the workflow.
How much does Silo Workspace cost per user?
Authentic8 prices it per user, per year, and every tier includes the full platform plus Nexus AI. Tiers differ only in regional coverage of the Silo network: one region, two regions, or all regions. No list price appears on the pricing pages reviewed here, so expect a quote.
Does Octo Browser have a free trial?
The Octo documentation reviewed here does not state trial terms, so check the vendor’s current page directly. On Send.win, paid plans start at $19/mo with a 7-day money-back guarantee on the first card purchase, and the free cloud demo needs no install.
Can Silo Workspace run multiple isolated sessions at once?
Authentic8 documents unlimited workspace configurations and says workspaces launch in seconds, with each session in its own container. Concurrency is a licensing question rather than a product one, so confirm simultaneous sessions for your tier with the vendor.
Do isolated browsers stop websites from detecting managed environments?
No. Directory listings for Silo note that some websites may still detect automated or managed browsing environments, and that platforms may restrict certain target sites. Isolation controls where sessions and data live, not how a site responds to you.
Is a cloud browser better than a local browser for research work?
Cloud sessions keep cookies, ETags and temporary files off your endpoint and destroy them at session end, which suits evidence collection and shared devices. Local profiles skip the streaming hop and keep working when your connection degrades. Choose by whether session data must be disposable or latency must be minimal.
What proxy types do these platforms provide?
Silo includes residential, mobile, data center and dark web connection types across 700+ in-region nodes, with private nodes for one mission. Octo supports HTTP, HTTPS, SOCKS5 and SSH plus WireGuard and AmneziaWG VPNs. Send.win includes metered residential proxies on Pro and Team and also accepts your own HTTP/SOCKS5 proxy.
How do Octo Browser and Silo Workspace handle profile persistence?
Silo persists browsing data, credentials and app state across sessions, then preserves or erases that state at deprovisioning when an investigation closes. Octo keeps profiles for 6 months after a subscription expires rather than deleting them, with per-profile cloud storage toggles deciding which data categories are stored.
