When your “safe tunnel” becomes a target
A VPN is meant to make remote work safer. It creates a protected connection between an employee and your business network—like a private tunnel into your systems.
But here’s the catch: the VPN login page is the entrance to that tunnel. If it’s exposed to the public internet and protected by only a password, it becomes a very attractive target.
Why this is dangerous
Hackers constantly look for VPN login pages. Once they find one, they try to get in by:
- Using stolen passwords (often purchased online or taken from older breaches)
- Tricking employees into giving up login info (phishing)
- Trying common passwords automatically until something works
- Exploiting outdated VPN software that hasn’t been updated—sometimes allowing access without logging in normally
The big issue: a VPN doesn’t just give access to one computer. It can provide a path into your entire network.
How to reduce the risk
You can keep the benefits of a VPN without leaving the door wide open:
- Only allow VPN access if you truly need it.
If some users or systems don’t require VPN access, don’t leave it turned on “just in case.” - Require multi-factor authentication (MFA) for every VPN user.
This is one of the strongest protections you can add. - Keep the VPN system updated.
VPN appliances and software need regular security updates, just like computers do. - Limit who can attempt to connect.
Restrict access to trusted devices and/or approved locations so random outsiders can’t even try.
The takeaway
Think of your VPN as a tunnel into a castle. It works great when only trusted people can open the gate.
But if the gate is always visible to the public—and guarded by nothing more than a password—you’re inviting trouble.
Use the tunnel only when needed, lock it down with MFA, keep it updated, and limit who can approach the entrance.
