Public Wi-Fi feels convenient, but it’s one of the easiest places for someone to quietly watch what you’re doing online. These networks are open by nature, which means your browsing, logins, and personal data can be visible to people on the same Wi-Fi. That makes airports, cafés, hotels, and other shared hotspots far riskier than they seem.
The moment you connect to these networks, you’re exposed in ways you can’t see. So, what actually makes public Wi-Fi risky, and why does it leave your data so vulnerable? And more importantly, what role can PureVPN play in keeping your public Wi-Fi connections secure? Learn all this and more below.
Why is public Wi-Fi so risky?
Here are some of the most common risks you’ll face on public Wi-Fi networks:
Packet sniffing
Public Wi-Fi makes it easy for someone on the same hotspot to watch the traffic that flows across it. While many websites encrypt their pages, plenty of information like the sites you visit and the apps you’re using can still leak out. Older or poorly built services may expose even more. Packet sniffing is one of the simplest ways attackers learn about your activity without ever touching your device.
MiTM attacks
An attacker can quietly slip between you and the site you’re trying to reach on an open Wi-Fi network. Everything looks normal on your screen, but your connection is being intercepted in the background, allowing someone to tamper with unencrypted traffic, redirect you, or collect information as it passes through. Because there are no obvious signs, man-in-the-middle attacks often go unnoticed.
Evil twin hotspots
Attackers can set up fake Wi-Fi networks that look identical to the real ones you expect to see in airports or cafés. You connect to them without a second thought, and suddenly all your browsing goes through a hotspot they control. From there, they can observe unprotected data or steer you toward malicious pages. Evil twin attacks work because the fake network blends perfectly with the real one.
Session hijacking
Many websites use something called session tokens to keep you logged in. If an app or service doesn’t protect these properly, someone on the same public Wi-Fi can capture them and slip into your account. They don’t even need your password, just the token that says you’re already signed in. Session hijacking mostly targets older or unsecured apps, but the risk increases on shared networks.
DNS spoofing
The Domain Name System is what helps your browser find the right website. Attackers can interfere with that process on public Wi-Fi and send you somewhere completely different, usually a fake login page or a malicious site designed to look legitimate. You typed the correct address, but the hotspot quietly directed you elsewhere. That silent redirect is what makes DNS spoofing so effective.
How does PureVPN protect you on public Wi-Fi
A VPN changes the way your data travels across a public hotspot so it’s no longer exposed to the people around you. Here’s what happens behind the scenes:
Your data is scrambled before it leaves your device
When you connect to PureVPN, the information you send like the sites you open or the accounts you sign into is turned into unreadable text. Anyone on the same Wi-Fi trying to look at passing traffic only sees noise, not what you’re actually doing.
Your traffic takes its own private path
Instead of moving through the public Wi-Fi in a way the network can inspect or tamper with, your data travels inside a protected channel straight to PureVPN’s server. Even if the hotspot is fake or misconfigured, your connection doesn’t depend on how safe the Wi-Fi is.
Your real online identity stays hidden
When your traffic reaches PureVPN’s server, it goes out to the internet using PureVPN’s IP address instead of the one tied to your personal connection. Those trying to trace activity back to you see PureVPN’s details, and not yours.
Your information stays unreadable the entire time
Everything that you send and receive remains scrambled from the moment it leaves your device until it reaches PureVPN’s server. At no point on the public Wi-Fi does it appear in a form anyone can use, which takes away the openings attackers normally rely on.
Steps to secure your public Wi-Fi connection with PureVPN
Protecting yourself on public Wi-Fi only takes a moment. Here’s the simplest way to stay safe whenever you’re using an airport, café, hotel, or any other shared hotspot:

- Connect to the public Wi-Fi as usual: Connect to the hotspot the same way you normally would. Once you’re online, you can turn on PureVPN to secure your connection before doing anything sensitive.
- Open PureVPN on your device: Launch the PureVPN app on your phone or laptop. It works the same way on public Wi-Fi as it does on your home network, so there’s nothing special you need to configure.
- Choose any server and connect: Pick a server that gives you good speed. Once the connection activates, your browsing and app traffic travel across the hotspot in a scrambled, protected form.
- Keep PureVPN running while you browse: Everything you send or receive stays inside the secure tunnel until you disconnect, even if the Wi-Fi drops for a moment or becomes unstable.
Tips to browse safely on public Wi-Fi
Public Wi-Fi can be useful, but a few simple habits make it far safer to use. These are some measures you should take alongside using PureVPN to protect yourself on shared networks:
Avoid accessing sensitive accounts
Try not to open banking apps, work dashboards, or anything that exposes personal details while you’re on public Wi-Fi. Even with protection in place, it’s better to save important tasks for a network you trust.
Stick to websites and apps that use HTTPS
Most sites encrypt their pages, but not all do. If a site loads without HTTPS, anything you enter on it may be exposed. PureVPN protects your connection, but avoiding unsecured sites adds an extra layer of safety.
Turn off sharing features
Options like file sharing, device discovery, or AirDrop can make your device more visible on public networks. Keeping them off reduces the ways someone on the same hotspot can interact with your device.
Disable auto-connect
Many devices try to join open networks on their own, which can accidentally connect you to a fake or unsafe hotspot. Turn off auto-join for public Wi-Fi so your device only connects when you choose to.
Use two-factor authentication
Even if someone captures your login details, they can’t get into your account without the second verification step. 2FA adds a simple but effective barrier that makes stolen passwords far less useful on public Wi-Fi.
Frequently Asked Questions
A VPN encrypts your internet traffic before it touches the public Wi-Fi, which means people on the same hotspot can’t read or intercept what you’re doing. It also sends your data through a protected tunnel to a secure server instead of exposing it on the shared network, significantly reducing the risks tied to open hotspots.
Yes, airport Wi-Fi is often crowded and fully open, so it’s easier for attackers to monitor or redirect traffic. A VPN scrambles everything you send and receive and keeps it inside a secure tunnel, preventing others on the same network from learning anything about your activity.
Absolutely! A VPN protects your phone the same way it does your laptop by encrypting your apps, browsing, and logins before they travel across the hotspot. As long as the VPN is connected, the public Wi-Fi can’t see your activity in a readable form.
A VPN blocks many common hotspot threats by hiding your traffic from people around you and preventing attackers from inspecting or tampering with it. It doesn’t fix unsafe websites or insecure apps, but it removes the visibility attackers rely on in places like cafés.
The best one should encrypt your traffic, prevent leaks, and stay stable even on crowded networks. PureVPN is built with these protections in mind, helping you stay safe when using shared hotspots.
Make sure the VPN offers strong encryption, modern VPN protocols, protection against DNS and IP leaks, and a kill switch that prevents data from escaping if the network drops. These features keep your work activity, logins, and files protected on public Wi-Fi.
