Does Your Business Need a VPN?
"Use a VPN" is everywhere as security advice — but it's one of the most misunderstood tools in IT. A VPN (virtual private network) creates an encrypted tunnel for your internet traffic. That's genuinely useful, but it's not the magic shield the adverts imply, and for a business the term covers two quite different things. Here's a plain-English look at what a VPN really does, what it doesn't, and whether your business actually needs one.
What a VPN actually does
- Encrypts your connection, so your data can't be read by others on an untrusted network — public café or hotel Wi-Fi being the classic example.
- Gives secure remote access to office systems — shared drives, servers, line-of-business apps — for staff working away from the premises.
- Hides your traffic from the local network you're connected to, and masks your location from the websites you visit.
Business VPN vs consumer "privacy" VPN
This is the distinction that causes most of the confusion. The VPNs advertised heavily online are consumer privacy VPNs — mainly about hiding your browsing and getting around regional restrictions. A business VPN is a different beast entirely: it's about securely connecting your staff to your own systems. Buying a consumer VPN subscription does nothing to give your team safe access to the office server, and a business setup isn't about anonymous browsing. Knowing which problem you're actually trying to solve is the first step.
The modern alternative: zero trust
For many small businesses, the traditional "tunnel everything back to the office" VPN model is being replaced by a zero-trust approach: instead of trusting anyone inside a network tunnel, you secure each application directly with strong identity checks and multi-factor authentication. If your systems live mostly in the cloud (Microsoft 365, Google Workspace and the like), zero trust is often simpler, faster and more secure than funnelling everything through one VPN. The right choice genuinely depends on where your data and applications actually live.
What a VPN doesn't do
This is where people get a false sense of security. A VPN is not antivirus and won't stop phishing, ransomware, malware or weak passwords. It protects data in transit — that's one layer of a much bigger picture. Treating "we have a VPN" as "we're secure" is a common and genuinely risky mistake; plenty of breaches have happened on networks that had a VPN the whole time.
The danger of a badly configured VPN
Worse than no VPN is a poorly set-up one. A business VPN with weak authentication, no MFA, or unpatched software doesn't just fail to help — it can become the way in for an attacker, a single front door to your whole network, while giving everyone a false sense that things are locked down. VPN appliances are a favourite target precisely because they're often left unpatched. If you run one, keeping it updated and protected with MFA is not optional.
Does your business actually need one?
Ask where your systems live and how your people work. If staff regularly need to reach in-office systems — a local server, shared drives, an on-premise application — from home or on the road, then properly configured secure remote access (a VPN or a zero-trust equivalent) is well worth it. If your team lives entirely in cloud services protected with MFA, your security priorities may lie elsewhere and a traditional VPN might add little. The answer is rarely "everyone needs a VPN" or "nobody does" — it's "it depends on your setup", which is exactly the kind of thing worth getting an honest assessment of.
Setting it up the right way
Whichever model fits, a few principles always apply: insist on MFA, keep everything patched, give people only the access they need rather than blanket entry, and choose a reputable business solution rather than a cheap consumer app pressed into service. Done well, secure remote access is invisible to your team and quietly does its job; done badly, it's either a constant frustration or a security hole.
We'll set it up right
Our cyber security and business IT support services design secure remote access that fits how your team actually works — whether that's a VPN, zero trust, or a sensible mix — and keep it patched and protected. See also our guide to setting up remote working securely.
