Do You Really Need a VPN?
Every VPN website will tell you that you need a VPN. They have strong financial incentives to do so. This guide is different — it tells you when a VPN is genuinely worth it, and when you are probably paying for something you do not need.
When You Actually Need a VPN
You use public WiFi regularly. Airport, coffee shop, hotel, a friend's house — any network you do not control is a potential attack surface. Someone on the same network can potentially intercept your traffic, read passwords, or access your accounts. A VPN makes this impossible. If you travel and work from public places, this is a genuine need, not marketing hype.
You are a journalist, researcher, or activist. If your work involves sensitive communications or you operate in a jurisdiction where internet activity is monitored, a VPN is a basic security tool — not a luxury. Combined with other practices (Signal, Tor, secure browsers), it is part of a layered approach to privacy.
You need to access work resources remotely. If you connect to your company's internal network, file servers, or applications from home, your employer almost certainly requires a VPN. Do not set up your own for this — use whatever your IT department provides.
You want to access streaming content from another country. If you travel internationally and want to watch your home country's Netflix, or want to access BBC iPlayer from outside the UK, a VPN is the standard solution. This is a legitimate use case that works reliably with the right VPN.
When You Probably Do Not Need a VPN
You are at home on your own private network. If you are on your home WiFi, your ISP's network is reasonably secure. Someone would need physical proximity or a compromised router to intercept your traffic. A VPN does add a layer of protection here, but for most people on a trusted home network, the incremental security benefit is small.
You just want to hide your browsing from your ISP. Yes, a VPN prevents your ISP from seeing your traffic. But your ISP can see that you are using a VPN, and VPN providers can see everything you do. You are trading one observer for another. If your ISP is the threat (say, they have a history of throttling BitTorrent), a VPN makes sense. If it is just general privacy, consider whether the VPN provider is actually more trustworthy than your ISP.
You think it makes you "anonymous." It does not. Logging into your Google account, using Facebook, or visiting websites with cookies in your browseridentifies you just as easily whether you are using a VPN or not. A VPN hides your IP address — a useful piece of data, but just one of many signals used to identify users online.
You are already using Tor. Tor Browser is designed for anonymity. Layering a VPN on top of Tor is debated among security experts — it can introduce additional trust points without meaningfully improving security for most users, and sometimes weakens your anonymity.
Common Misconceptions
"Free VPNs are fine for casual use." Running a VPN network costs real money — servers, bandwidth, staff, infrastructure. If a company offers a free product, they are making money somehow. Studies repeatedly find that free VPNs harvest and sell user data, inject ads, and sometimes bundle malware. ProtonVPN's free tier is the one exception worth trusting, because the company's business model is built on paid subscriptions, not data.
"All VPNs are the same." Not even close. Some keep detailed logs despite claiming they do not. Some have catastrophic security breaches and cover them up. Some are operated by companies in surveillance-friendly jurisdictions. Some have been served subpoenas and had to hand over what data they had. The difference between a trustworthy VPN and a sketchy one is enormous.
"A VPN will protect me from everything." A VPN is one tool, not a security suite. It does not protect against phishing, malware, weak passwords, or using the same password on every site. If you are clicking links in suspicious emails, no VPN will save you.
What a VPN Cannot Do
- Make you completely anonymous online
- Protect you from phishing or social engineering attacks
- Prevent websites from tracking you through cookies, fingerprints, or account logins
- Protect you from your own bad password habits
- Speed up your internet (it will usually slow it down slightly)
- Unblock every streaming service (streaming platforms actively block VPN IPs)
The Verdict
A VPN is a genuine security tool for specific use cases: public WiFi, remote work access, accessing content from other countries, and situations where you need protection from network-level surveillance. If one or more of those applies to you, it is worth paying for a trustworthy provider.
If your situation is "I want more privacy generally" and "I browse from home on my own WiFi," the case is weaker. A VPN adds some protection but trades your ISP's visibility for your VPN provider's visibility. Whether that trade is worth it depends on how much you trust each party.
The worst reason to buy a VPN is because "everyone needs one" and "you'll be tracked without it." That is marketing, not security advice.
