The basics

VPN — What Does It Actually Do?

VPN stands for Virtual Private Network. It does two things simultaneously: encrypts your internet traffic and hides your real IP address by routing your connection through a server in another location.

Think of it like sending a letter. Without a VPN — your internet provider sees the recipient, the content, and your return address. With a VPN — your provider only sees that you sent an encrypted package to one location. What's in that package and where it goes next — they can't see.

How the technology works

VPN Encryption — How It Works

When you connect to a VPN, your device creates an encrypted tunnel to the VPN server. All your internet traffic travels through this tunnel — your ISP only sees encrypted data going to the VPN server, nothing else.

Modern VPNs use AES-256-GCM encryption — the same standard used by banks, governments and the military. Breaking AES-256 by brute force would take longer than the age of the universe, even with every computer on Earth working together.

When to use it

Do You Need a VPN?

Yes, you probably do — if any of these apply:

  • You use public Wi-Fi (airports, cafés, hotels): Open networks are easy to intercept. A VPN encrypts everything regardless of the network's security.
  • You want streaming from other countries: Netflix USA has ~3,000 more titles than Netflix Poland. NordVPN unlocks 15+ libraries, ExpressVPN unlocks 20+.
  • You care about ISP privacy: Your internet provider legally can — and in some countries must — record your browsing history. A VPN prevents this.
  • You torrent: VPN hides your IP from BitTorrent swarms and copyright trolls. Only use VPNs with audited no-logs policies (NordVPN: 5× audited).
  • You travel to censored countries: China, Russia, UAE block major websites and apps. A VPN with obfuscation (ExpressVPN Lightway, NordVPN Obfuscated) bypasses the Great Firewall.

You probably don't need a VPN if: you only ever use your own secured home network, you're not concerned about ISP data collection, and you don't travel internationally.

Common myths

VPN Myths — Debunked

❌ VPN makes you completely anonymous
⚠️ Partially true. VPN hides your IP and encrypts traffic, but you can still be identified via cookies, browser fingerprinting, and account logins. It's one layer of privacy — not total anonymity.
❌ Free VPNs are just as good as paid
False. Most free VPNs log your data and sell it to advertisers — that's their business model. The only trustworthy free VPN is ProtonVPN Free (unlimited bandwidth, no logs, audited).
❌ VPN is illegal
False in most countries. VPNs are legal in the EU, USA, UK, Australia, Canada and most of the world. They are restricted (not banned) in Russia and UAE. Banned only in North Korea, Belarus, and Chinese citizens.
❌ VPN dramatically slows your internet
Modern VPNs lose 5–15% speed on nearby servers. In our tests, NordVPN retains 95.3% of a 1 Gbps connection on Polish servers — you won't notice the difference.
❌ You need technical knowledge
Modern VPN apps (NordVPN, Surfshark, CyberGhost) are one-tap connect. Install → tap "Connect" → done. No configuration required.

A VPN is an app that encrypts your internet connection and hides your real IP address. Your internet provider sees only that you're connected to a VPN server — not which websites you visit or what you download.

Yes — in most countries including the entire EU, USA, UK, Canada and Australia. VPNs are restricted (not banned) in Russia and UAE. See our full VPN legality guide →

A good VPN on a nearby server loses only 5–15% speed. NordVPN retains 95.3% of a 1 Gbps line in our tests. On a standard 100 Mbps home connection you won't notice any difference.

A VPN routes your traffic through one server — fast, suitable for streaming and everyday use. Tor routes through 3+ random servers — very slow but more anonymous. For most people, a VPN is the right choice.

Your ISP can see you're connected to a VPN server but not what you're doing through it. With obfuscated servers (NordVPN, ExpressVPN) even this is hidden — traffic looks like regular HTTPS.
