Remote desktop tools (like Microsoft Remote Desktop, AnyDesk, or similar) are designed for convenience. Your IT provider—or someone on your team—can log into a computer from anywhere, fix an issue, and move on. No onsite visit. No downtime waiting for help.
That convenience is exactly what makes it risky when it’s set up the wrong way.
The convenience that can turn into a problem
If remote desktop access is left open to the public internet, it’s not just your IT team who can find it.
Hackers run automated “search tools” around the clock looking for businesses that have remote access exposed. When they find one, they try to get in by:
- guessing weak passwords,
- using stolen usernames and passwords (often bought online),
- or taking advantage of known software weaknesses that weren’t patched.
And once they’re in, they don’t just “peek around.” They can take control—just like a legitimate user.
Real-world impact
Remote desktop exposure is a popular entry point for ransomware and other attacks because it’s:
- fast (easy to find),
- simple (often protected by only a password),
- and sometimes unnoticed until damage is already done.
If your remote access setup isn’t locked down, you’re increasing the odds that you’ll eventually deal with a serious cyber incident.
How to protect your firm (without losing convenience)
You can still use remote access—just put it behind the right protections:
- Don’t leave it open to the public internet.
Route remote access through a secure “front door” (like a VPN or a modern secure access tool). - Require multi-factor authentication (MFA).
So a stolen password alone won’t get someone in. - Limit where logins can come from.
Only allow access from approved locations or devices (like your IT provider’s systems). - Watch for suspicious activity.
Have tools in place that can flag unusual behavior—like logins at odd hours or unexpected software being installed.
The takeaway
Think of remote desktop like a garage door opener. It’s incredibly convenient—until someone else gets a copy of the remote.
If you don’t absolutely need that access exposed to the world, close it—and make people go through a secure entry point instead.
