ProtonVPN vs PIA in 2026: Privacy Specialist or Budget Powerhouse?

ProtonVPN and Private Internet Access get recommended for almost opposite reasons. ProtonVPN is the Swiss privacy specialist built by the team behind Proton Mail. PIA is the American budget option with a server count that dwarfs almost everyone else’s. Comparing them head to head shows exactly where each one earns its reputation, and where it doesn’t.

The quick verdict

ProtonVPN wins on overall score (4.24/5 vs 3.64/5), largely on the strength of its jurisdiction, its KPMG-audited no-logs policy, and its transparent ownership. PIA answers back with a server network of nearly 29,000 servers in 77 countries, a lower long-term price, and encryption settings you can tune yourself.

If jurisdiction and independent verification matter most to you, ProtonVPN is the stronger choice. If you want the largest server footprint on the market at the lowest price, PIA is genuinely competitive, provided you’re comfortable trusting a court record instead of an audit report.

Head-to-head comparison

Jurisdiction: Switzerland pulls ahead

This is the category where the two VPNs diverge most. ProtonVPN is based in Switzerland, outside any surveillance-sharing alliance and protected by some of the strongest data privacy law in Europe. It scores a full 5/5 on jurisdiction.

PIA is incorporated in the United States, a Five Eyes member with a legal system that can compel companies to hand over data through subpoenas and national security requests. That earns it a 3/5. For most everyday users this gap is theoretical. For journalists, activists, or anyone whose threat model includes government requests, it is the single biggest reason to lean ProtonVPN.

No-logs claims: audit versus courtroom

ProtonVPN’s no-logs policy was last verified by KPMG, one of the “Big Four” accounting firms, giving it a clean 5/5 on our audit criterion. Independent audits are the gold standard because a third party actually inspects the infrastructure rather than taking the company’s word for it.

PIA has never commissioned a formal third-party no-logs audit, which is a real gap. What it has instead is a rarer form of proof: on at least two occasions, US courts have subpoenaed PIA for user data related to criminal investigations, and PIA had nothing to produce because nothing was logged. That’s not a paper audit, but it is hard evidence collected under legal pressure, which is why we still score it 4/5.

Encryption: PIA’s default is weaker, but configurable

This is PIA’s clearest technical weak point. Out of the box, PIA defaults to AES-128 encryption rather than AES-256, which is why it only scores 2/5 on our encryption criterion. AES-128 is not broken or considered unsafe by any credible standard, but it is a lower security margin than what ProtonVPN and most competitors ship by default. PIA does let you manually switch to AES-256 in the app settings, so the fix is available, it’s just not the default.

ProtonVPN ships AES-256 by default across the board and scores 4/5 here. Neither VPN uses ChaCha20 as its default cipher, which is one reason both sit slightly behind providers like NordVPN or Surfshark on this specific metric.

Server network: PIA’s biggest advantage

PIA operates close to 29,000 servers in 77 countries, one of the largest networks of any VPN on the market. ProtonVPN runs a leaner 2,950 servers across 65 countries. In practice, more servers generally means less congestion during peak hours and more granular city-level location choices, both of which PIA delivers.

ProtonVPN compensates with its free tier, unique among major VPNs, and with Secure Core, a feature that routes traffic through hardened servers in privacy-friendly countries before it exits to the wider internet. Raw server count isn’t everything, but for users who split traffic across many simultaneous locations, PIA’s network depth is a real advantage.

Ownership and transparency: a wide gap

ProtonVPN is run by Proton Technologies AG and scores 4/5 on ownership transparency. PIA is owned by Kape Technologies, the same parent company behind ExpressVPN and CyberGhost, and scores just 1/5 here, the same low mark every Kape-owned brand gets on our table. Kape doesn’t hide its ownership, but its history in the adware business before pivoting to VPNs is the reason the score stays low across its entire portfolio.

Streaming and everyday use

Neither of these is primarily a streaming VPN. ProtonVPN scores 4/5, reliably unblocking Netflix but delivering inconsistent results on Disney+, BBC iPlayer, and Peacock. PIA scores 3.5/5, with similarly mixed results across the same platforms. If unblocking streaming libraries is your main use case, our best VPN for Netflix guide points to stronger dedicated options.

Price: PIA wins on the long-term plan

PIA’s 1-year plan works out to roughly $3.33 a month, with a 2-year plan totaling $79. ProtonVPN’s 1-year plan lands around $4.99 a month, with a 2-year total of $71.76. Both providers offer a 30-day money-back guarantee, and neither offers a free trial, though ProtonVPN’s permanent free tier functions as a way to test the service without any commitment at all.

Torrenting and P2P support

Both VPNs are solid choices for torrenting, though for different reasons. PIA supports Shadowsocks and offers dedicated IP add-ons, both useful for users who want a consistent, unblocked connection for P2P traffic without repeatedly triggering anti-VPN measures on torrent trackers. Its enormous server count also means less congestion on P2P-friendly servers during peak hours.

ProtonVPN allows P2P traffic on most of its servers and includes Secure Core routing as an option, which adds a privacy layer for torrenting through hardened, privacy-jurisdiction servers before traffic exits to the wider internet. Its smaller server count is less of a downside here than it is for streaming, since torrenting doesn’t depend on unblocking region-specific content.

Neither VPN publishes a hard cap on P2P bandwidth, and both include a kill switch, which matters more for torrenting than almost any other use case: a dropped connection mid-download exposes your real IP to every peer in the swarm instantly.

Apps and platform coverage

ProtonVPN covers Windows, macOS, Linux, iOS, Android, and smart TV apps, but has no dedicated Chrome or Firefox browser extension, scoring 3/5 on our availability criterion. PIA covers the same core platforms plus both Chrome and Firefox extensions, and additional platform support beyond the standard list, scoring 4/5.

For users who want a lightweight browser-only VPN for quick tasks alongside a full desktop client, PIA’s extension support gives it a practical edge. ProtonVPN’s apps are generally considered cleaner and simpler to navigate, which matters if you’re setting this up for a less technical family member rather than yourself.
