Vale la pena usare una VPN? Un onesto crollo
24 giugno 2026 · 3 minuti di lettura · Commenti
Gli annunci VPN sono ovunque: su YouTube, podcast e ogni sito tecnologico. La maggior parte di loro sopravvaluta ciò che effettivamente fa una VPN. Ecco uno sguardo onesto su quando una VPN aiuta davvero e quando no.
Cosa fa realmente una VPN
- 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.

Quando una VPN aiuta davvero
- 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.
Quando una VPN NON aiuta
- 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.

Quale VPN utilizzare
- 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.
Se utilizzi regolarmente il Wi-Fi pubblico, una VPN vale $ 5-10 al mese. Se navighi principalmente da casa su una rete affidabile, il vantaggio è minore, ma la sola protezione dal tracciamento dell’ISP è una ragione sufficiente per molte persone.
