Work can happen anywhere now—on a managed laptop, a personal Mac, a borrowed Chromebook, or a contractor’s machine you’ll never control. That flexibility fuels productivity, but it also increases risk. One risky click, one unpatched plugin, or one “just for this campaign” browser profile can expose accounts and data.
Remote Browser Isolation (RBI) flips that risk model. Instead of letting websites run on your device, RBI runs the page remotely and streams an interactive view back to you. The result is safe, policy-controlled access to the web from any device—including unmanaged or BYOD—without slowing your team down.
In this guide, you’ll learn what RBI is, how it works (pixel streaming vs. DOM mirroring), where it shines for BYOD and hybrid teams, and why Sendwin—a cloud browser at https://send.win—is a practical way to bring RBI benefits into everyday workflows. No extensions. No local installs. Just safe, flexible browsing that supports multi-login at scale.
What Is Remote Browser Isolation (RBI)?
RBI keeps risky web code off your endpoint. A remote server fetches and renders the page, executes scripts, and handles all the messy parts. Your device receives only a safe, interactive representation of that session—like a high-fidelity stream. Because nothing from the original site executes on your machine, malware, zero-days, and drive-by downloads don’t land on your device.
RBI also pairs beautifully with zero-trust security. You can enforce least-privilege policies right at the session layer—disable form input on suspicious pages, limit uploads or downloads, redact sensitive fields, and gate permissions by risk level.
How RBI Works: Pixel Streaming vs. DOM Mirroring
There are two common ways to deliver an isolated browsing experience:
- Pixel streaming (sometimes called “pixel pushing”). A real browser runs remotely and streams the visuals to you, similar to a responsive remote desktop. This keeps all original page content and code off the endpoint.
- DOM mirroring (reconstruction). The provider reconstructs a safe version of the page on your device based on a sanitized model from the remote browser. This can be very fast while still reducing risk.
Both isolate risk. Pixel streaming maximizes separation because nothing from the original page executes locally. DOM mirroring can feel extra snappy in some cases. Many platforms blend techniques or switch modes based on content type. Your choice depends on your use case, latency needs, and data-exfiltration controls.
Why RBI Matters for BYOD and Unmanaged Devices
Today’s teams are fluid: agencies, contractors, freelancers, and remote hires often use their own machines. Traditional controls—heavy agents, strict MDM, or mandatory VPNs—can be hard to deploy, intrusive, or simply not an option.
RBI makes device posture less critical because the risky part (the browser session) runs off-device. You can grant temporary, policy-controlled access from any machine without leaving behind sensitive cookies, tokens, or downloads.
Benefits teams typically see:
- Malware stays off endpoints. Active content runs remotely; your device gets only a safe, interactive view.
- Built-in phishing friction. You can add warnings, disable form fields on suspicious pages, or require extra confirmation before posting credentials.
- Lower compliance footprint. Fewer local artifacts to audit on personal hardware.
- Faster onboarding/offboarding. Provision access to a browser session—not to the device. When a project ends, access ends with it.
Cloud Browser vs. Legacy Approaches (VPN, Profiles, VDI)
If you’ve tried to scale multi-login and safe browsing with older tactics, you’ve felt the pain:
- Profiles/incognito/secondary browsers separate identities a bit, but they still execute code locally and can bleed system context. They don’t stop malicious scripts.
- VPNs protect traffic in transit but don’t isolate the browser; hostile pages still run on your device.
- Full VDI isolates well but can be heavy, costly, and overkill for everyday web tasks.
A cloud browser using RBI delivers an easier middle ground: agentless, fast isolation that spins up in seconds, keeps the endpoint clean, and lets each login live in its own tab. For multi-account and BYOD scenarios, that’s the sweet spot.
Meet Sendwin: Zero-Trust Cloud Browser for Multi-Login + Isolation
Sendwin is a cloud browser designed for teams that juggle many logins and want secure, separate, and speedy workflows. Instead of extensions or local profiles, each login runs in its own isolated, cloud-hosted tab—a real desktop browser streamed to you—so sessions never collide and nothing executes on your machine. No client install required.
Because Sendwin follows RBI principles, it’s ideal for secure access from any device—including unmanaged laptops and contractor machines—while still delivering everyday productivity wins for marketers, e-commerce operators, SEO pros, developers/testers, remote workers, and power users.
What Makes Sendwin Different
- Real browsers on real computers. Sendwin runs custom desktop browsers inside virtual machines. This isn’t an emulator or a “fake” browser, so modern sites work as expected.
- Agentless by design. Launch sessions from a dashboard. No extension or client install needed for the cloud version—perfect for BYOD or locked-down environments.
- Zero-trust browser isolation. Keep browsing secure, private, and non-attributable. Nothing from the original site runs locally.
- Built for multi-login. Open several accounts on the same site at once, each with its own storage, identity, IP, and optional proxy.
Key Features of Sendwin (and Why They Matter)
These capabilities help teams move faster while reducing risk. (Availability may vary by plan.)
Multiple Logins Made Easy
Run many accounts on the same site side-by-side. Skip relogins and tab gymnastics. This is a huge time saver for social, ads, marketplace ops, and customer support workflows.
Session Isolation on Every Tab
Each tab is a fully independent browser with separate cookies, cache, and local storage. You can A/B test copy and creatives without cross-contamination, and sensitive sessions stay separated.
Different Browsers in a Single Window
No more juggling secondary browsers or private windows. Keep everything in one interface while Sendwin handles the isolation under the hood.
Premium Proxy Add-On (Bring Your Own Proxy)
Attach proxies per session to keep identity consistent, test geo-specific experiences, and route traffic per client. Ideal for ad verification, SEO checks, and marketplace operations.
Protect Every Session Page
Blur or block sensitive pages (like billing or account settings) when sharing a session for review, training, or QA. Keep credentials and private data out of recordings and live shares.
Share Account, Not Password
Grant a teammate time-boxed access to a live session so they can work “as if” they’re logged in—without ever seeing the password. Revoke access with a click.
Session Timer per Session
Set a one-hour, 30-minute, or one-day access window for a specific session. Great for contractors, reviewers, or quick approvals.
Blur Pages on Demand
Need to redact something right now? Blur sensitive views in one click and keep the workflow moving.
We Protect Your Privacy
No shared storage. Tabs and websites can’t silently monitor activity across sessions. Cookies, cache, and local storage are isolated to each tab.
Rock-Solid Security
Sendwin emphasizes strong encryption—AES-256 for symmetric operations and RSA-2048 for asymmetric operations—alongside an isolation model where content never executes on your endpoint.
Switch Accounts with Ease
Hop between live sessions without relogging—perfect for social scheduling, multi-brand support, or agency workflows.
Zero-Trust Browser Isolation
Browse privately and non-attributably with minimal endpoint risk. Sensitive tokens and cookies stay off your local machine.
IP/Location Anonymity
Match each session with a specific proxy or region to maintain consistent location signals per client or test.
No VPN/Client Install Required
Because the browser is cloud-hosted, access is agentless. That’s a big win for BYOD or environments where software installs are restricted.
Nightly Version Updates
Let Sendwin handle browser patching and upgrades. Security teams love having fewer local dependencies to manage.
Isolation From Malware/Phishing
Agentless, isolated sessions mean malicious code never runs on your device. This lowers the blast radius of phishing and drive-by attacks.
Disposable Browser
Spin up clean, single-use environments for research, competitor checks, or “open this unknown link” moments—then dispose of them when you’re done.
Real Browsers Running on Real Computers
Compatibility matters. Sendwin uses custom desktop browsers on real VMs so sites behave like they do locally—minus the risk.
Safe Browsing, No Time Limits on Paid Plans
Run long test cycles or ongoing operations without per-session countdowns on paid tiers.
Intuitive Interface
A clean, simple dashboard helps non-technical users get value right away—launch, switch, share, and protect sessions with minimal setup.
Global Endpoints
Choose locations in the Americas, Europe, or Asia for better performance and realistic geo testing.

Security and Privacy Model in Plain English
What executes where?
In the cloud version of Sendwin, all page code runs in Sendwin’s infrastructure. Your laptop receives an interactive stream from a real desktop browser in a virtual machine. That means no active web code runs on your device—you get RBI benefits without heavy VDI.
What gets stored locally?
Because sessions are isolated per tab/server, cookies, cache, and local storage are siloed in Sendwin’s environment and not shared across tabs. That reduces cross-session tracking and keeps local machines clean.
How is each session protected?
Sendwin uses strong encryption (AES-256 and RSA-2048) and practical session controls (blur, block, timers, permissions). Combined with isolation, this helps contain malware, phishing, and accidental data leakage.
Why BYOD loves this model.
You can grant access to a session without touching the user’s device, installing an agent, or trusting the endpoint. When a contractor leaves, you revoke session access—no awkward “please wipe your laptop” requests.

RBI FAQs (Quick Answers)
Is a cloud browser the same as RBI?
A cloud browser implements RBI by running sessions remotely and streaming the results back. Different providers use different rendering methods, but the core idea is the same: keep risky code off your device.
Will it feel slow?
Modern streaming and smart policy enforcement feel natural for standard SaaS work. Choosing a region (Americas, Europe, Asia) helps minimize latency.
What about phishing?
RBI lets you add guardrails—warnings, input restrictions, and extra prompts—so credential theft is less likely.
Why not just use profiles or incognito?
Profiles separate identities but still run code locally. They don’t prevent malware, trackers, or rogue scripts from touching your device. RBI does.
Are these “real” browsers?
Yes. Sendwin runs real desktop browsers on server VMs for full site compatibility, streamed securely to your device.
