ProtonVPN Review

How we tested

We bought a Proton VPN Plus subscription at $9.99 for one month on a personal Visa card and used it as a regular customer. We did not request press access. We tested Proton across three cities on 1 Gbps symmetric fiber lines (Chicago, Los Angeles, New York) over 12 days. Our rigs:

• Windows 11 tower (Intel i7‑12700F, 32 GB RAM, Intel i225‑V 2.5 GbE NIC) on wired Ethernet.
• MacBook Pro M2 (2022) on wired Ethernet via Thunderbolt adapter.
• iPhone 15 Pro and Pixel 7 on Wi‑Fi 6 (separate SSID, no mesh backhaul congestion).

We ran 3,412 total speed measurements: baseline (no VPN) and VPN on WireGuard and OpenVPN UDP, using the Ookla CLI and iPerf3 to fixed endpoints in the same city, same region (500–1,000 miles), and intercontinental (New York–London, Los Angeles–Tokyo). Tests were scheduled at 8:00, 13:00, 18:00, and 23:00 local time to capture peak and off‑peak conditions. We pinned servers by city where Proton exposed city‑level choices; otherwise we used the provider’s nearest server. We repeated each test set three times and logged median values. All software updates were frozen during runs.

For privacy checks, we ran extended tests on dnsleaktest.com and ipleak.net on each platform (Windows, macOS, Android, iOS), five repetitions per platform, with and without the kill switch. We toggled IPv6 on the LAN to watch for leaks. We also stress‑tested the kill switch by yanking the Ethernet cable mid‑session and by forcing the Proton app to crash.

Streaming checks covered eight services: Netflix (US and UK libraries), Hulu, Disney+, BBC iPlayer, Max, Amazon Prime Video, and YouTube TV. Each service got three attempts on different days and times, using fresh browser profiles and native apps where relevant. We recorded a success only if we could play a full episode or movie for 10 minutes without a proxy error.

Customer support timing was measured with three tickets (setup, streaming, and billing questions) submitted over three days at morning, afternoon, and late‑night hours. We looked for live chat, documented first‑response times, and graded answer quality on specificity and actionability.

Speed in real-world use

Proton’s WireGuard implementation is fast on nearby servers and holds up across regions, with a sharper drop on long‑haul routes and when you enable its Secure Core multi‑hop. On our 1 Gbps lines, baseline median downlink hovered at 937 Mbps and uplink at 935 Mbps across cities.

Same‑city on WireGuard, Proton delivered a median 872 Mbps down and 848 Mbps up. That’s a 7%–9% loss versus baseline. On a 500 Mbps home plan, that drop would still leave you with roughly 455–465 Mbps. Regional (500–1,000 miles) medians were 761 Mbps down and 734 Mbps up (19%–22% loss). Transatlantic (New York to London) landed at 604 Mbps down and 588 Mbps up, with latency climbing from 9 ms baseline to 84 ms through the tunnel. Transpacific (Los Angeles to Tokyo) was the toughest: 488 Mbps down and 471 Mbps up, 48%–50% off baseline with 121 ms latency.

Enable Secure Core (double‑hop through Switzerland or Iceland), and you pay a real tax. US to US via a Swiss Secure Core path dropped to 312 Mbps down (−67%) and added 24–36 ms of latency on local routes. That still streams 4K, but large game downloads feel slower. Our longer Secure Core paths (US→CH→UK, US→IS→JP) dipped to 220–280 Mbps down.

OpenVPN UDP was consistently slower than WireGuard, which matches our experience across providers. Same‑city OpenVPN medians were 318–352 Mbps down (62%–66% loss). If your router only supports OpenVPN, plan on that range.

Jitter stayed low on nearby WireGuard servers (1.2–2.9 ms). We saw more variance on transpacific routes (5–11 ms jitter), which lines up with longer RTTs. Across the four daily test windows, speed stability was solid. Same‑city downlink 5th–95th percentile spread was 826–903 Mbps; regional spread was 712–786 Mbps. Peak‑hour slowdowns were present but not severe, generally 4%–8% off the day’s median.

Proton’s “VPN Accelerator” is a set of multi‑threading and routing optimizations. With the toggle on, our same‑city WireGuard median improved from 851 to 872 Mbps on Windows and 816 to 838 Mbps on macOS. That’s a 2%–3% bump. It did not change long‑haul medians in a way we could separate from normal variance.

Mobile results over Wi‑Fi 6 were good. Baseline on the iPhone 15 Pro was 612 Mbps down. Proton on WireGuard landed at 520 Mbps (−15%). On a 200 Mbps cable line, a similar 15% loss would still be 170 Mbps.

In short: Proton is quick when you stick to WireGuard and nearby servers. It keeps respectable rates across the Atlantic. It falls off on transpacific and multi‑hop routes, as expected.

Security and privacy

Proton is based in Switzerland. That matters if you care about legal process. Swiss data‑retention rules do not require logging VPN traffic, and cross‑border requests go through mutual legal assistance channels. Proton’s policy says it does not log user activity or IPs. We read Proton’s transparency report and legal assistance pages; requests are summarized there with case counts, and the company says its no‑logs stance limits what it can hand over.

Apps are open source across platforms. Proton has published third‑party audits of its apps in recent years. We reviewed the public reports linked from its site and GitHub; these covered client code and found medium‑to‑low severity issues that were remediated. We did not find a recent, provider‑wide “no‑logs” audit of server‑side systems by a Big Four or Cure53/Deloitte‑style firm. If you want a documented no‑logs audit that inspects back‑end access controls and logging pipelines, that’s a gap.

Protocol selection is modern. WireGuard (ChaCha20) is the default in our apps. OpenVPN UDP/TCP is available for filtering‑restricted networks. Proton also offers a Stealth mode to obfuscate traffic; in our tests, Stealth connected reliably from a corporate guest network that blocked standard VPN ports, though throughput dropped to 110–190 Mbps.

The kill switch and “always‑on” worked. On Windows and macOS, we cut the physical link and force‑quit the app. No traffic escaped during reconnection in 12/12 tries. DNS requests stayed on Proton’s resolvers. Across 60 leak runs (extended dnsleaktest and ipleak), we saw zero DNS, IPv4, or IPv6 leaks. IPv6 routes were either tunneled or cleanly blocked depending on platform settings.

Proton’s Secure Core is a multi‑hop option that routes through hardened entry points in Switzerland or Iceland before exiting elsewhere. It’s useful if you’re worried about exit‑node monitoring, but you should expect a 40%–70% speed hit on most paths based on our measurements.

NetShield, Proton’s ad/malware/tracker filter, blocked ad domains on our usual test pages and didn’t break login flows on banking or shopping in our week of use. It’s DNS‑based, so it won’t catch every inline tracker, but it meaningfully cuts noise without needing a browser extension.

Account setup requires an email address. We paid by card. The brand advertises privacy‑friendly payment options like cryptocurrency; we did not test cash or crypto. Device limit is 10 on the Plus plan. Router support is manual via OpenVPN or WireGuard config files; there’s no native router app.

Bottom line on privacy posture: Swiss jurisdiction, open‑source clients, clean leak tests, and working kill switch are strong signals. Lack of a recent, broad no‑logs audit keeps us cautious in how far we extrapolate.

Where it falls short

• Streaming is good, not flawless. In our 24‑trial battery, Proton unblocked 6 of 8 services reliably. BBC iPlayer worked 1 of 3 times, and Amazon Prime Video failed all three due to proxy errors. We could usually fix Hulu and Max by switching UK or US servers, but it took trial and error. If your goal is “press play on any service, first try, any night,” Proton misses that bar some nights.

• Secure Core is too slow for many everyday tasks. The privacy value of a multi‑hop is real, but our Secure Core medians fell 40%–70% versus single‑hop WireGuard. That pushes 4K streams close to their margins on weaker home lines and makes big updates drag. The app labels the feature clearly but does not estimate the likely speed hit per path. You have to discover that yourself.

• No dependable live chat. We could not reach an agent in real time. Email replies were detailed and polite, but ranged from under 3 hours to over 11 hours. That’s fine for setup questions, not for “my streaming is down during a live game.”

• macOS and iOS feature gaps. Split tunneling is available on Windows and Android; we did not have it on iOS, and Proton’s macOS app lacked a full per‑app split tunnel in our build. If you want to exclude your banking app or a game from the VPN on Apple devices, you’re out of luck.

• Price beats the most expensive players but not the value leaders. At $4.99/mo on a two‑year term, Proton undercuts premium brands that sit near $6.67/mo, but it’s still pricier than deals we measured from budget leaders that start around $2–$2.50/mo. If you’re optimizing purely for cost per device, Proton’s 10‑device cap versus unlimited‑device rivals also reduces its value for large households.

• Router support is manual. There’s no native router firmware or app. If you want whole‑home coverage, you’ll be loading config files and troubleshooting yourself. Our OpenVPN router tests on an AsusWRT box topped out near 220–280 Mbps, much slower than PC WireGuard.

Who should NOT buy this

Skip Proton if you want a “stream anything, anywhere” tool with near‑perfect consistency. In our tests, Proton got us into Netflix, Disney+, Hulu, and Max most of the time, but BBC iPlayer was hit‑or‑miss and Prime Video failed. If that’s a deal‑breaker, pick a service with a stronger eight‑for‑eight streaming record in our runs.

Price hunters with many devices should also look elsewhere. If you need coverage for 15–20 phones, tablets, TVs, and consoles, a provider with unlimited devices at roughly $2–$2.50/mo on a long plan will be cheaper and simpler. Proton’s 10‑device cap means juggling logins or leaving some gear off.

If you rely on real‑time support, Proton’s email‑only flow will frustrate you the night something breaks. Several competitors answered us on live chat in under 2 minutes with working fixes. Finally, if you plan to run your VPN on a router and want a point‑and‑click setup, Proton’s manual configs and lower OpenVPN router speeds are not the easy path.

The competition

NordVPN was faster and more consistent at streaming in our tests. On the same rigs, Nord’s WireGuard‑based protocol (NordLynx) posted a same‑city median of 905 Mbps down (−3% vs baseline) and 690 Mbps transatlantic, compared to Proton’s 872 and 604 Mbps. Nord unblocked all 8 of our services across 24 attempts, including BBC iPlayer and Prime Video, and its live chat answered in under 2 minutes with specific server picks when we asked. Nord’s two‑year plan also ran cheaper in our price check ($3.39/mo at the time of testing) and now allows 10 devices. Where Proton pulls ahead: fully open‑source apps, Swiss jurisdiction, and the Secure Core multi‑hop option for users who want a hardened entry path. If your top priority is privacy posture and transparent client code, Proton has the edge.

Surfshark traded blows on speed and dominated on price and device count. We measured a same‑city median of 860 Mbps down (−8%) and 630 Mbps transatlantic on its WireGuard stack, a bit slower than Nord but a hair faster than Proton on long‑haul in our sessions. Streaming was 7/8 across our attempts; Prime Video worked twice and failed once. Surfshark’s two‑year plan priced out around $2.19/mo in our snapshot and supports unlimited devices, which is compelling for large households. Proton beats Surfshark on app transparency (open source) and on having a built‑in multi‑hop that routes through Switzerland or Iceland. Surfshark’s live chat was fast, though, and its automation rules are broader on desktop. If you want the highest privacy ceiling, we’d still pick Proton; if you want to cover every device cheaply, Surfshark is hard to argue against.

If you’re deciding among these three: choose Nord for all‑around speed and streaming with quick support, Surfshark for price and unlimited devices, and Proton if privacy posture and open clients matter most and you can live with occasional streaming gaps.

Bottom line

ProtonVPN is a strong pick for privacy‑minded buyers who want WireGuard speeds, open‑source apps, and clean leak protection, and who can tolerate a few streaming misses. It’s priced mid‑pack: cheaper than the priciest “premium” names, but more than the value leaders, with the two‑year plan at $4.99/mo and a 10‑device cap.
