When you use public WiFi, staying safe online is important. Some people recommend using a Virtual Private Network (VPN), while others think it’s not always needed. Let’s explore what a VPN does and whether it’s still useful today.

What Does a VPN Do?
A VPN is like a shield for your internet traffic. It scrambles, or encrypts, the data you send and receive, which adds extra security when you're using public WiFi. This used to be super important when most websites didn’t use HTTPS (the little lock icon in your browser). Back then, hackers could easily spy on what you were doing.
Now, with most websites using HTTPS, your data is already encrypted between you and the site. But here’s the catch: HTTPS doesn’t hide which sites you visit from the WiFi owner or a sneaky hacker on the same network. A VPN steps in here. It hides your activity from the WiFi owner but shifts trust to your VPN provider. That means the VPN provider could technically see what you're doing, so you’ll need to choose one you trust.
Why Public WiFi Isn’t Always Safe
Public WiFi can be risky. Hackers sometimes create fake networks that look real. If you connect to one, they might be able to spy on your online activity and grab sensitive information.
Even with HTTPS protecting most websites, not every site is secure. If you accidentally visit one without HTTPS, your data could be exposed. Hackers also use tricks like DNS spoofing, which can send you to fake websites that look real. Thankfully, modern browsers usually warn you about unsafe sites, which helps a lot.
What VPNs Can and Can’t Do
VPNs are helpful, but they’re not a perfect solution. If most of the websites you visit already use HTTPS, the extra encryption a VPN provides might not make a big difference.
VPNs are important because they protect your privacy by hiding your browsing activity and help keep your online experience secure, even on shared networks.
But remember, even with a VPN, your safety depends on how secure the websites you visit are. If a site has weak security, a VPN can’t fix that.
Should You Use a VPN on Public WiFi?
Using a VPN on public WiFi can still be a good idea. Here’s why:
- Extra Security: Public WiFi isn’t always safe. A VPN adds an extra layer of protection by encrypting all your internet traffic.
- Privacy: A VPN hides your online activity from the WiFi owner, so they can’t see what sites you visit.
- Defense Against Attacks: VPNs help protect you from common public WiFi threats, like fake networks or eavesdropping.
- Safer Online Activities: If you’re doing sensitive things like banking or shopping online, a VPN keeps your data more secure.
Conclusion
With most websites using HTTPS, VPNs aren’t as essential as they used to be, but they’re still useful. Public WiFi comes with risks, and a VPN is one of several tools you can use to stay safe.
The key is to understand what VPNs and HTTPS can and can’t do, so you can make smarter choices about protecting your information online.
