You've seen the ads. VPN companies position themselves as the missing piece of your online security. But is a VPN really what's missing? Most people don't fully understand what a VPN actually does — and that gap in understanding is exactly what the marketing exploits. Here's what you should know before you assume you're protected.
If you've spent any time online recently you've probably seen a THAT NordVPN ad [with the motorcycle]. The pitch is compelling: your browser security isn't complete without a VPN. Millions of people have signed up believing a VPN is a core piece of their security stack.
It isn't. A VPN is a privacy tool. A useful one in the right context - but a privacy tool nonetheless. The gap between what VPNs are marketed as and what they actually do is significant, and that gap is where people get hurt.
Here's what a VPN does and doesn't do, in plain language.
Myth 1: A VPN keeps you safe online
Reality: A VPN encrypts your connection. That's it.
Think of a VPN as a tunnel. Your internet traffic travels from your home through that tunnel and emerges from a server somewhere else. The website you're visiting sees the server's location, not yours. Your internet provider can't see what you're doing inside the tunnel. Anyone trying to snoop on your connection on the same network gets encrypted gibberish.
That's genuinely useful in specific situations. But it's a very narrow form of protection.
Here's what the tunnel doesn't do: it doesn't evaluate the sites you visit. It doesn't flag suspicious links. It doesn't protect you from handing your email address, password, and credit card number to a site that will leak them in a data breach next year. Once your data leaves your device and lands in someone else's database, the fact that you visited using a VPN is completely irrelevant.
Myth 2: A VPN protects you from phishing and malware
Reality: A VPN has no ability to evaluate whether a site is safe.
This is where the marketing gets genuinely misleading. A VPN routes your traffic - it doesn't inspect it. It has no mechanism to look at the site you're visiting and determine whether it's a legitimate bank login page or a convincing fake designed to steal your credentials.
If you click a link in a phishing email and land on a fake DocuSign page, your VPN will dutifully encrypt your connection to that fake page. It won't warn you. It won't block you. It won't do anything differently than it would if you visited the real DocuSign. We showed exactly what one of these attacks looks like in a real example.
Some VPN providers have started bolting on basic malware blocking as an add-on feature — NordVPN's Threat Protection is one example. This is worth knowing. But these features are secondary additions to a privacy tool, not the core function. They work by checking URLs against known threat databases, which means they have the same structural limitation as every other signature-based tool — they miss attacks that launched this morning.
We wrote about why signature-based tools have this limitation by design
Does a VPN protect against phishing? No. Not in any meaningful way.
Myth 3: A VPN is all the protection you need
Reality: A VPN solves one specific problem. Online safety requires more than one layer.
The "all you need" framing is the most dangerous myth on this list because it creates exactly the kind of false confidence that makes people vulnerable.
A VPN does not protect you from:
Phishing attacks that trick you into handing over your credentials
Malicious extensions installed in your browser
Data breaches at companies that already hold your information
Fake websites that look identical to real ones
Scam emails designed to manipulate you into sending money
What VPN limitations mean in practice is that a person who relies solely on a VPN for their online security has one narrow layer of protection and significant gaps everywhere else. Those gaps are exactly where modern attacks operate.
Layered protection is the honest answer. A VPN for connection privacy on untrusted networks. Browser-level protection (like Haven) for the sites you visit and the links you click. Email scanning for the messages hitting your inbox. Each tool covers what the others can't. None of them alone is enough.
Myth 4: VPN companies are security companies
Reality: They are privacy companies. That distinction matters.
This is the myth that the industry itself perpetuates most aggressively. The ads, the branding, the language — it's all designed to position VPNs as comprehensive security solutions. They aren't.
Privacy and security are related but different things. Privacy is about who can see your data and where it goes. Security is about keeping bad actors from accessing or compromising it. A VPN addresses the first. It has almost nothing to say about the second.
The security industry has a long history of using fear to sell products that provide narrower protection than advertised. VPNs are one of the clearest examples of that pattern. Understanding what you're actually buying is the first step to knowing what else you need.
What VPNs are actually good for
To be fair - and fairness is the point of this post - VPNs are genuinely useful in specific situations:
Public WiFi. If you're working from a coffee shop, airport, or hotel, a VPN protects your connection from anyone snooping on that network. This is the use case VPNs were built for and where they perform well.
Hiding your location. If you want to browse without websites knowing your home IP address or approximate location, a VPN does that cleanly.
Accessing content in other regions. Streaming services, region-locked content, browsing from countries with restricted internet access — VPNs handle this well.
These are real, legitimate use cases. If they apply to you, a VPN is worth having. Just don't confuse having a VPN with being protected online.
The honest bottom line
A VPN is a privacy tool doing privacy work. It is not a security tool. It won't catch the phishing email heading for your inbox, flag the fake site you're about to enter your password into, or alert you when a browser extension is doing something it shouldn't.
If your goal is genuine online security — not just privacy — you need tools built for that specific job. A VPN is not one of them.
Haven works at the browser level to catch what VPNs structurally can't — flagging suspicious sites, scanning emails, and alerting you before you hand anything over to a site that isn't what it looks like. Download Haven free from the Chrome Web Store.
