The Short Answer

Remote desktop can be safe. But most people use it in ways that aren't. The difference comes down to three things: how your connection is established, who can see your traffic, and whether the vendor has already been hacked.

Let's break each of those down — with real examples, not theoretical hand-wringing.

The Real Risks (Not the Paranoid Ones)

When people ask "is remote desktop safe?", they usually mean one of these:

  1. Can someone hack into my computer through it? — Yes, if you expose RDP to the internet without protection (the #1 attack vector for ransomware in 2024-2025).
  2. Can the remote desktop company see my screen? — With most apps, technically yes. Your stream routes through their servers.
  3. What if the company gets breached? — Then your credentials, session tokens, and potentially your data are compromised. This has happened. Twice. Recently.

When It Goes Wrong: Real Breach Stories

These aren't hypothetical scenarios. They happened.

⚠️ AnyDesk Breach — February 2024

AnyDesk confirmed that hackers compromised their production systems and stole source code and code-signing certificates. They had to revoke all security certificates and reset every customer password. The breach went undetected for weeks before disclosure. If you were using AnyDesk during that period, attackers potentially had the keys to impersonate their software.

⚠️ TeamViewer Breach — June 2024

TeamViewer disclosed that a Russian state-sponsored group (APT29/Cozy Bear — the same group behind the SolarWinds attack) breached their corporate network. TeamViewer claimed the breach was limited to their internal IT environment, but the attacker is one of the most sophisticated in the world. When APT29 gets in, they don't usually leave empty-handed.

The pattern is clear: centralized remote desktop vendors are high-value targets. They hold credentials for millions of machines. Breach one vendor, access millions of endpoints. It's the ultimate supply-chain attack.

The Architecture Problem

Most remote desktop apps work like this:

  1. You install the app on both machines
  2. Both machines connect to the vendor's server
  3. The vendor's server brokers the connection
  4. Your video stream and input data flow through (or are relayed by) their infrastructure

This means the vendor is a man in the middle. Even if they encrypt the connection, they hold the keys. Even if they say they don't look at your data, they could. And if they get breached, the attacker inherits that capability.

💡 P2P vs. Relay: Why It Matters

Peer-to-peer (P2P) connections go directly between your two machines. No server in the middle. No one to intercept. Combined with end-to-end encryption (E2E), even the app vendor can't see your data — because they never have the keys. This is how Remio works: the signaling server only helps your devices find each other. After that, data flows directly between them, encrypted with keys only your devices hold.

Windows RDP: The Elephant in the Room

If you Google "remote desktop security," most results are about Microsoft's Remote Desktop Protocol (RDP). And for good reason — exposed RDP is the single biggest attack surface for ransomware.

Here's the problem: RDP was designed for internal corporate networks. Exposing it directly to the internet (port 3389) is like leaving your front door open with a sign that says "everything valuable is inside."

Attackers run automated scanners 24/7 looking for open RDP ports. When they find one, they brute-force the password. If you're using a weak password or no MFA, they're in. From there, it's ransomware, data exfiltration, or both.

"In 2025, exposed RDP was the initial access vector in over 60% of ransomware incidents." — Multiple threat intelligence reports

If you use Windows RDP: never expose it to the internet without a VPN or zero-trust network. Better yet, use a purpose-built remote desktop app that handles the networking for you.

What to Look for in a Secure Remote Desktop App

Not all remote desktop apps are created equal. Here's what matters:

1. End-to-End Encryption (E2E)

Your stream should be encrypted with keys that only your two devices hold. The vendor should not be able to decrypt your session. Ask: "If your servers were compromised, could an attacker see my screen?" If the answer is anything other than "no," walk away.

2. Peer-to-Peer Connections

Your data should flow directly between devices whenever possible. Relay servers should be a fallback, not the default. P2P means less data exposure, lower latency, and no central point of failure.

3. No Account Required

Every account is a credential that can be phished, leaked, or stolen in a breach. The safest credential is the one that doesn't exist. Some apps (like Remio) use temporary PINs instead of accounts — there's nothing to steal.

4. Open Security Architecture

Can you read about how their encryption works? Do they publish security whitepapers? Have they been audited? Transparency isn't just nice-to-have — it's how you know they're not cutting corners.

5. Minimal Permissions

Does the app ask for permissions it doesn't need? Does it run background services? Does it phone home with telemetry? The best security is a small attack surface.

Do You Need a VPN?

It depends on the app.

If you're using Windows RDP directly: yes, absolutely. A VPN creates a secure tunnel that prevents your RDP port from being exposed to the internet.

If you're using a modern remote desktop app with E2E encryption: a VPN is redundant for the remote desktop connection itself. The app already encrypts everything end-to-end. A VPN on top of that just adds latency with no security benefit.

That said, a VPN can still be useful for other reasons — hiding your IP, accessing geo-restricted content, or satisfying corporate compliance requirements. Just don't confuse "I have a VPN" with "my remote desktop is secure." They're different things.

Why We Built Remio's Security This Way

We designed Remio's security model around a simple principle: we shouldn't have to be trusted.

Your connection is peer-to-peer. Your encryption is end-to-end — keys are generated on your devices and never leave them. We don't require an account, so there are no credentials to steal. Our signaling server sees only encrypted metadata (which devices want to connect), never your actual screen or input data.

If our servers were compromised tomorrow, an attacker would get... a list of anonymous device IDs that once tried to connect to each other. No passwords. No session recordings. No screen data. Nothing useful.

That's not because we're more virtuous than other companies. It's because we architected the system so that even a compromised Remio can't hurt you. We think that's how all remote desktop software should work.
