What Does VPN Do?
🔍 Quick answer:
A VPN does five key things: 1) Hides your real IP address, 2) Encrypts your internet traffic, 3) Protects you on public Wi-Fi, 4) Lets you bypass geo-restrictions to access content from other countries, and 5) Stops your ISP from seeing and selling your browsing history.
The 5 things a VPN actually does
1. Hides your IP address and location
Websites see the VPN server's IP, not yours. This makes it look like you're browsing from wherever that server is located — great for privacy and accessing region-locked content.
2. Encrypts your internet traffic
All your data becomes unreadable gibberish to anyone who intercepts it. Your ISP, hackers on public Wi-Fi, and government agencies can't see what you're doing online.
3. Protects you on public Wi-Fi
Coffee shops, airports, hotels — these networks are often unencrypted and easy to hack. A VPN encrypts everything, making it useless for attackers.
4. Bypasses geo-restrictions
Connect to a server in another country and you can access content that's normally blocked there — like US Netflix abroad, BBC iPlayer outside the UK, or websites censored in your region.
5. Stops ISP spying
Your internet service provider can see every website you visit without a VPN. With a VPN, they only see you're connected to a VPN server — not what you're doing.
What a VPN does NOT do
Block malware
VPNs aren't antivirus software
Stop cookies
Websites can still track you with cookies
Make you anonymous
If you log into accounts, they still know who you are
💡 Pro tip: A VPN is just one tool in your privacy toolkit. For maximum privacy, combine it with a privacy-focused browser (Firefox with privacy extensions), use a search engine like DuckDuckGo, and be mindful of what accounts you're logged into.
