Vyplatí se VPN? Poctivé členění
24. června 2026 · 3 minuty čtení · Komentáře
Reklamy VPN jsou všude – na YouTube, v podcastech, na každém technologickém webu. Většina z nich přeprodává to, co VPN skutečně dělá. Zde je upřímný pohled na to, kdy VPN skutečně pomáhá a kdy ne.
Co vlastně VPN dělá
- A VPN (Virtual Private Network) routes your internet traffic through a server run by the VPN company, then out to the internet. This has two effects:
- Websites you visit see the VPN server's IP address, not yours. So your location and identity are hidden from those sites.
- Your internet provider (ISP) can see you're connected to a VPN, but cannot see which sites you're visiting.

Když VPN skutečně pomáhá
- Public Wi-Fi. Coffee shops, airports, and hotels run open networks where other users can sometimes intercept unencrypted traffic. A VPN prevents this. This is the single most compelling everyday use case.
- Stopping your ISP from selling your browsing data. ISPs in many countries are legally allowed to log and sell your browsing history. A VPN stops this, though you're now trusting the VPN company instead.
- Accessing geo-restricted content. Netflix libraries, BBC iPlayer, sports streams. A VPN lets you appear to be in a different country.
Když VPN nepomůže
- Hiding from Google or Facebook. You're logged into these services. They know exactly who you are regardless of your IP address. A VPN does nothing here.
- Complete anonymity. You can still be tracked via browser fingerprinting, cookies, and account logins. A VPN masks your IP — that's all.
- Security on its own. A VPN doesn't protect you from phishing, malware, or weak passwords. It's not a replacement for good security habits.

Jakou VPN použít
- Mullvad — the most privacy-focused option. Accepts cash payment, requires no email to sign up, has a strict no-logs policy that has been independently audited. €5/month.
- ProtonVPN — based in Switzerland (strong privacy laws), open-source, audited, has a free tier. Excellent choice for most people.
- Avoid free VPNs unless they're from a trusted provider like Proton. Free VPN companies often make money by logging and selling your data — the exact opposite of why you'd use a VPN.
Pokud pravidelně používáte veřejné Wi-Fi, VPN stojí 5–10 $ měsíčně. Pokud většinou prohlížíte z domova v důvěryhodné síti, přínos je menší – ale samotná ochrana ISP před sledováním je pro mnoho lidí dostatečným důvodem.
