The VPN you bought to keep attackers out just became a way in

A quick, plain-English translation of a security headline that actually matters this month — and what it means for your business.

Most companies let people work from home or on the road through a VPN (a Virtual Private Network) — the secure connection that lets an employee's laptop reach the company's systems as if they were sitting in the office. Think of it as a side door you open on purpose, with a good lock on it.

In early June, the maker of a widely used VPN product warned that attackers had found a way to walk through that door without a password. The whole point of a VPN is to check "are you allowed in?" — and this flaw let attackers skip that check completely. And it wasn't just theory: criminals had quietly been using it for about a month before anyone noticed.

Here's why that's serious. At least one of these break-ins has been tied to a ransomware gang — the kind of attack that locks up all your files and demands a payment to get them back. Once someone is through the VPN, they're standing inside the trusted part of your network, which is exactly where that kind of damage begins.

The alarm was raised by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) — the federal agency that warns American businesses about active threats. CISA gave companies only about three days to fix this. When the government puts a clock that short on something, it's saying, in plain terms: this is already being used against real people, so don't wait.

The part the scary headlines leave out

This is not an everyone-panic moment, and I won't pretend it is. The flaw only affects systems set up a specific, outdated way — old configurations that should have been retired years ago. If your equipment is reasonably current, your risk is low. The businesses getting hurt are the ones who didn't realize they were still running the old setup.

I point that out on purpose. Fear isn't a strategy, and an advisor who sounds the alarm over every headline gets tuned out right before the one that truly matters. The useful reaction isn't panic — it's simply knowing what you actually have, and keeping it current.

What this means for you

You don't need to touch any of this yourself. You just need to ask the right questions and get clear answers. This week, ask whoever handles your technology — your in-house person or your outside IT provider — three things:

1. "Do we use a VPN for remote access, and is it fully up to date?" If they can't answer right away, that's a reason to dig further.
2. "When the government flags an urgent threat like this, how fast can we actually apply the fix?" The right answer is hours or a day — not "we'll get to it eventually."
3. "If we had been exposed before the fix, how would we know whether anyone already got in?" Closing the door matters; so does checking whether someone already slipped through it.

If any of those gets you a shrug, the real problem isn't this one flaw — it's that nobody is watching your doors closely enough. That's the thing worth fixing, and it's far cheaper to handle before an incident than after one.

The tools you buy to keep attackers out can quietly become the way in — if no one keeps them current. Watch the doors first.
