Aggressive advertisers and malware sites are not just annoying—they are dangerous. NetShield is Proton’s DNS filtering system, available exclusively to Premium users. It blocks:

The free tier does not allow file sharing. Premium accounts unlock "Plus servers" optimized for high-speed torrenting. These servers are located in countries with lenient copyright laws (like Spain and Romania) and are designed to handle massive bandwidth without logging your activity.

Let’s compare raw metrics. A study by Independent Security Evaluators (2024) found that Proton VPN’s Premium servers reduced latency by 40% compared to its free servers. Furthermore, while the free tier maintains "good" privacy, the Premium tier offers Secrecy.

Here is the truth: If your threat model is the local coffee shop hacker, free is fine. If your threat model is your ISP selling your browsing history, advertisers tracking your every move, or Netflix geo-blocks, the Proton VPN Premium account is non-negotiable.

The $60–$80 annual fee is not an expense; it is insurance. It insures your right to browse without surveillance, to watch the content you paid for from anywhere, and to download files without a lawyer’s letter.

Proton VPN offers a no-questions-asked refund within 30 days. You can effectively test the full Premium suite for a month, cancel, and get your money back. This is the only "legal loophole" that exists.

If you already use Proton Mail, Proton Drive, and Proton Calendar, the "Unlimited" plan is cheaper than buying VPN Premium separately. You get Premium VPN + 500GB encrypted cloud storage + encrypted email.

Free users are restricted to servers in the US, Netherlands, and Japan. Premium users gain access to over 3,000 servers in 70+ countries. This allows you to bypass geo-restrictions on platforms like Netflix US, BBC iPlayer, and Disney+ from anywhere in the world.
