Are you wondering if a VPN is right for you? We first published this article in 2012, and while the internet has changed a lot since then, the core reasons to use a VPN have only become stronger. Here are the practical reasons, updated for today.
A Virtual Private Network creates an encrypted tunnel between your device and a VPN server. Everything you send and receive passes through that tunnel, so the network you are on — and your internet provider — can only see that you are connected to a VPN, not what you do. Websites see the server's IP address instead of yours.
Key takeaways
- A VPN protects everything you do on public Wi-Fi, where anyone nearby can try to intercept traffic.
- It hides your real IP address and location from the websites and services you use.
- It stops your ISP from logging and profiling your browsing or throttling specific traffic.
- It helps you reach content and calling apps that are blocked on your local network.
- HTTPS is great, but it doesn't hide which sites you visit, your DNS lookups or your IP — a VPN does.
1. Securing wireless connections and public Wi-Fi
If you use wireless hotspots or public Wi-Fi, your traffic can be monitored both by whoever provides the access and by others on the same network — they often all share the same password. Back in 2012 a browser extension called FireSheep showed how trivially an attacker in a coffee shop could hijack other people's logged-in sessions on popular social networks.
Most sites now use HTTPS, which closes that particular hole, but public Wi-Fi is still risky: fake “evil twin” hotspots with the same name as the real one, captive portals that inject content, DNS hijacking, and apps that still send some data unencrypted. With a VPN, even on a network with no security at all, everything leaves your device already encrypted.

2. Hiding your IP address and protecting your privacy
As you visit websites, information about you is stored in databases: your IP address, approximate location, the pages you view and when. Combined with cookies and browser fingerprints, it builds a detailed profile.
When you connect to a PD-Proxy server, your IP address is masked by the server's IP. All traffic you send and receive passes through our server, so your online presence is “masked” behind it. Any website or online service will see our server's address, not yours. Try it: check What is my IP? before and after connecting.
A VPN hides your IP, but it doesn't make you invisible if you log in to accounts or accept tracking cookies. Combine it with a privacy-respecting browser and good cookie habits.
3. Preventing passive monitoring by your ISP
All traffic passing from your computer to the internet can be monitored and logged by your internet service provider. Even with HTTPS, your ISP can see the domain names you look up and connect to, and many providers mention in the fine print of their terms that they collect and may share this metadata.
With PD-Proxy, all traffic is encrypted from your device to our VPN server before it goes to the internet — including DNS lookups, which go to our private resolvers inside the tunnel. Your ISP sees one encrypted connection and nothing else.
4. Preventing bandwidth throttling and traffic shaping
Some ISPs and mobile operators slow down particular types of traffic at busy times — video streaming, voice calls or large downloads. Because a VPN hides the ports and protocols inside the tunnel, the provider can no longer single out specific services for slower treatment. If your connection is being shaped, a VPN often restores normal speeds; if it isn't, a nearby server with WireGuard keeps the overhead small. See How to make your VPN faster.
5. Getting around censorship and blocked services
Schools, workplaces, hotels and some countries block websites, messaging or VoIP calls. A VPN connection reaches the open internet from our server, so local filters can't see what you access. On networks that block VPNs themselves, PD-Proxy's Stealth mode wraps the tunnel in ordinary-looking HTTPS on port 443. Always respect the rules and laws that apply to you.
6. Using your services while travelling
We have servers in many countries. When you travel, some websites and online services treat you differently depending on the country your IP address comes from — banking sites may flag logins from abroad, and some services are only available in certain regions. Connecting to a server in your home country gives you a familiar, consistent connection wherever you are. Please make sure you follow the terms of the services you use.
7. One tool for every app on every device
Unlike a proxy, which only covers the application you configure, a VPN protects every app on your device automatically: browser, e-mail, messaging, games, updates. One PD-Proxy Premium account covers up to 5 devices at the same time. Learn more in VPN vs Proxy vs Tor.

Frequently asked questions
Is using a VPN legal?
In most countries, yes. A VPN is a standard security tool used by businesses and individuals. What matters is what you do with it — illegal activity stays illegal. A few countries restrict VPNs, so check local rules.
Does a VPN protect me from viruses?
No. A VPN protects your data in transit; keep your system updated and use reputable security software as well.
Will a VPN slow me down?
Encryption and distance add a little overhead, but with a nearby server most people notice little difference in everyday use.
Can I try it for free?
Yes. A free PD-Proxy account gives you 1 GB per day on our demo servers.
Conclusion
Whether you want to secure public Wi-Fi, keep your ISP out of your business or simply stop websites from knowing where you are, a VPN is one of the simplest and most effective privacy tools available. Premium unlocks every server with unlimited bandwidth.
