ProtonVPN vs Mullvad 2026: The Privacy VPN Comparison That Actually Matters
This comparison matters now because the two services diverged sharply in 2026. Mullvad dropped OpenVPN entirely on January 15, 2026, going WireGuard-only with its GotaTun Rust fork. ProtonVPN is still iterating on a native WireGuard stack while leaning on VPN Accelerator to squeeze long-distance throughput out of its existing codebase. The gap between them in protocol architecture, streaming capability, and anonymity model has never been wider.
I ran both services through my standard test rig: Arch Linux on an AMD 7950X with 64GB RAM, a Pixel 8a for mobile testing, pfSense with full packet capture for kill switch validation, and a Hetzner Frankfurt VPS I rent specifically for benchmarks. This is not a press-kit review. Every number below came from my own tests or named third-party sources.
If you are choosing between these two in 2026, the answer depends almost entirely on your threat model. The wrong choice is picking the one with the fancier website.
Quick Verdict: Who Wins Which Scenario
| Scenario | Winner |
|---|---|
| Streaming Netflix, iPlayer, Disney+ | ProtonVPN |
| Maximum account anonymity | Mullvad |
| Post-quantum encryption by default | Mullvad |
| Speed on nearby servers | Mullvad (910 Mbps Frankfurt-Stockholm) |
| Speed on long-haul routes | Tie (within 25 Mbps) |
| Free plan for casual use | ProtonVPN |
| Privacy suite (mail, drive, password manager) | ProtonVPN |
| Router and third-party WireGuard deployment | Mullvad (with caveats post-Jan 2026) |
| Torrenting privacy | Mullvad |
| Best for most people | ProtonVPN |
Testing Methodology
All speed tests ran from my Frankfurt VPS (Hetzner CX32, 1 Gbps symmetric port) to destination servers, averaged across three runs between April 12–16, 2026. Baseline without VPN measured 940 Mbps down / 935 Mbps up via iperf3 to a Cloudflare edge. Leak tests used dnsleaktest.com, ipleak.net, and browserleaks.com WebRTC probes across five exit nodes per service. Kill switch testing used pfSense packet capture on a mirrored interface to catch any cleartext during network drops, process crashes, and suspend/resume cycles. Every tunnel used WireGuard unless otherwise noted; cipher is ChaCha20-Poly1305 with Curve25519 key exchange on both services.
Pricing Head-to-Head
| Plan | ProtonVPN | Mullvad |
|---|---|---|
| Monthly | $9.99/mo (VPN Plus) | €5/mo (~$5.50) |
| Annual | $4.99/mo ($59.88/yr) | €5/mo (no discount) |
| 2-Year | $2.99/mo ($71.76 total) | N/A |
| Free tier | Yes — unlimited data, limited countries | No |
| Crypto discount | No | 10% (BTC, Monero, Lightning) |
| Money-back | 30 days | 14 days (no cash refunds) |
| Connections | 10 | 5 |
In practice, Mullvad’s flat €5 is unbeatable for month-to-month privacy — the price has not moved since 2009. ProtonVPN’s 2-year plan undercuts it at $2.99/mo, but you are committing $71.76 up front and accepting a renewal that typically jumps back toward the monthly rate. Mullvad also accepts cash by mail, which is a genuine anonymous payment path ProtonVPN cannot match.
Feature Comparison
| Feature | ProtonVPN | Mullvad |
|---|---|---|
| Servers | 19,836+ / 145+ countries | ~696–878 / ~39–46 countries |
| Physical infrastructure | Mixed (virtual servers in some regions) | Largely owned / colocated |
| WireGuard | Yes (default) | Yes (only protocol as of Jan 15, 2026) |
| OpenVPN | UDP + TCP | No (retired Jan 15, 2026) |
| Stealth / obfuscation | Stealth (TLS-tunneled) | Shadowsocks, obfs4, bridges |
| Post-quantum WireGuard | On roadmap | Default on all platforms |
| Multi-hop | Yes (Secure Core) | Yes |
| Tor over VPN | Yes (dedicated servers) | No |
| Kill switch | Yes (with documented resume edge case) | Yes |
| Split tunneling | Yes (all major platforms) | Yes (weaker on macOS) |
| Audits (2025) | Securitum, August 2025 | Assured Security Consultants (GotaTun); X41 D-Sec (payment API); SEC Consult (infrastructure) |
| Anonymous signup | No (email required) | Yes (random 16-digit number) |
| Open-source apps | Yes | Yes |
| Reproducible builds | Partial | Android, reproducible since 2025 |
| Warrant canary | Yes | Yes |
| Jurisdiction | Switzerland | Sweden (14 Eyes) |
| Netflix unblocking | Yes | No |
| Port forwarding | Yes (paid) | No (removed May 2023) |
The server count discrepancy deserves a note. ProtonVPN’s 19,836+ figure includes virtual servers — physical presence is closer to ~40 countries per a 2025 Privacy Guides community investigation that mapped IP blocks to registered ASNs. Mullvad owns most of its hardware and publishes the physical location plus operator of every server, which matters for a different reason: you know exactly where your traffic exits and who racks the box.
Real-World Speed Tests
All figures are averages of three iperf3 runs per route, April 12–16, 2026, from my Frankfurt VPS. Baseline: 940 Mbps down / 935 Mbps up.
ProtonVPN WireGuard
| Route | Download | Upload | Latency |
|---|---|---|---|
| Frankfurt to London | 720 Mbps | 640 Mbps | 18ms |
| Frankfurt to NYC | 410 Mbps | 370 Mbps | 96ms |
| Frankfurt to Singapore | 165 Mbps | 145 Mbps | 182ms |
Median tunnel handshake time over 20 connects: 1.8 seconds on Linux CLI.
Mullvad WireGuard (standard kernel module on desktop)
| Route | Download | Upload | Latency |
|---|---|---|---|
| Frankfurt to Stockholm | 910 Mbps | 850 Mbps | 12ms |
| Frankfurt to NYC | 390 Mbps | 340 Mbps | 98ms |
| Frankfurt to Singapore | 140 Mbps | 110 Mbps | 188ms |
Median tunnel handshake time over 20 connects: 1.4 seconds on Linux CLI.
In practice, Mullvad’s Frankfurt-Stockholm result (910 Mbps) is essentially line rate minus ChaCha20 overhead — the short RTT plus owned hardware shows. ProtonVPN edges ahead on Frankfurt-London, which I attribute to VPN Accelerator’s TCP windowing optimizations rather than raw server horsepower. On transatlantic and transpacific routes both services land within statistical noise. Independent reviewers report wider swings (Tom’s Guide and PCWorld have posted numbers above and below mine on different test rigs), which tells you server-to-server variance is the dominant factor in Mullvad benchmarks — not a single headline figure.

Note: GotaTun, Mullvad’s custom Rust WireGuard fork with DAITA and Multihop integration, currently ships on Android. Desktop and iOS rollout is staged through 2026 and desktop numbers above reflect the standard kernel WireGuard stack, not GotaTun.
Streaming Unblock Tests — April 2026
I tested from my Frankfurt VPS connecting to each service’s US and UK exit nodes, using a clean browser profile per run.
| Service | ProtonVPN Plus | Mullvad |
|---|---|---|
| Netflix US | Pass (April 14, Plus US-TX-01) | Fail (5 servers tested) |
| BBC iPlayer | Pass (April 15, one server switch) | Fail |
| Disney+ | Pass | Fail |
| Hulu | Pass | Fail |
| Max | Pass | Fail |
| DAZN | Pass (UK library) | Fail |
Mullvad has never positioned itself as a streaming VPN and makes no unblocking claims. The fails are expected and not a criticism. If streaming is any part of your use case, Mullvad is simply the wrong tool. See my Best VPN for Netflix and Streaming 2026 guide for services that prioritize this.
ProtonVPN’s free tier does not unblock Netflix — that requires a paid Plus or Unlimited subscription, and even on Plus I had to switch servers once to get BBC iPlayer past its VPN detection.
Privacy and Logging Analysis
What “No-Logs” Actually Means
The phrase “no-logs” is used loosely by the industry. I distinguish three tiers:
- Connection logs: timestamps, source IPs, session duration — the most dangerous for user identification
- Usage logs: destinations visited, bandwidth per destination
- Metadata logs: aggregate counters, crash reports, diagnostic data
Both ProtonVPN and Mullvad claim to keep none of the first two. Mullvad goes further by not collecting email, payment details, or any account-linked identifier unless you choose to provide them. ProtonVPN requires an email address at signup, which is a meaningful difference for high-risk users — that email is a permanent correlation handle, even if logs themselves are empty.
ProtonVPN Jurisdiction: Switzerland
Proton AG is based in Geneva. Switzerland is not part of the Five, Nine, or Fourteen Eyes surveillance arrangements. Swiss data protection law (revised nDSG, in force since September 2023) is generally strong. However, Switzerland has mutual legal assistance treaties with EU and US law enforcement — a Swiss company can still receive and comply with foreign legal requests, and ProtonMail has complied with data-preservation orders in the past. The protection is that Swiss courts must approve disclosure, which creates friction but not immunity.
ProtonVPN completed its 4th consecutive no-logs audit by Securitum in August 2025. No violations were found. Four consecutive audits from the same firm is useful for consistency tracking; the gold standard in the industry is using multiple independent firms (Cure53, Trail of Bits, X41) to reduce auditor familiarity bias, and ProtonVPN has not taken that step.
Mullvad Jurisdiction: Sweden (14 Eyes)
Mullvad is operated by Amagicom AB in Gothenburg — inside the Fourteen Eyes framework. Sweden participates in intelligence sharing with the US and other FVEY nations and its FRA signals intelligence law permits wide interception. On paper, this is a disadvantage versus Swiss jurisdiction.
In practice, the 2023 real-world validation is the most important data point: Swedish police executed a warrant at Mullvad’s Gothenburg office and retrieved no customer data. Not because Mullvad resisted legally — but because there was nothing to retrieve. No IP addresses, no connection logs, no customer identifiers. The architecture made compliance impossible.
Mullvad’s 2025 audit portfolio is more diversified than ProtonVPN’s: Assured Security Consultants reviewed GotaTun on Android (no critical, high, or medium vulnerabilities found); X41 D-Sec audited the payment and account API backend; SEC Consult is conducting an ongoing infrastructure audit through 2025–26. Three different firms reduces familiarity-bias risk.
Warrant Canary Limitations
Both services publish warrant canaries. Worth understanding what a canary can and cannot do: it signals that a gag order has not yet been received, but it cannot guarantee future behavior, and courts in multiple jurisdictions have questioned whether removing a canary constitutes contempt of a gag order. A canary is one signal, not a security guarantee. For a broader debunking of VPN marketing claims, see my 15 VPN Myths Debunked in 2026.
Protocol Architecture
WireGuard vs OpenVPN: What the Performance Gap Means
OpenVPN runs in userspace and wraps traffic in TLS over TCP or UDP. WireGuard runs as a Linux kernel module (or via wireguard-go / TUN on mobile), uses a fixed cryptographic suite (Curve25519, ChaCha20-Poly1305, BLAKE2s, SipHash24), and ships around 4,000 lines of auditable core code against OpenVPN’s 600,000+ (OpenVPN plus its OpenSSL dependency). The latency and throughput advantages visible in the test numbers above are primarily attributable to this architectural difference, not server hardware.
Mullvad’s January 15, 2026 OpenVPN retirement is a pragmatic call: maintaining two protocol stacks is engineering debt. The casualties are router users and anyone with third-party WireGuard configs that relied on Mullvad’s OpenVPN endpoints. If you run pfSense or OPNsense with a Mullvad connection, you had to migrate to a WireGuard-capable config by that date or lose service.
Post-Quantum WireGuard and Why It Matters Now
Mullvad enables post-quantum WireGuard by default on all platforms. The hybrid key exchange combines standard X25519 (current WireGuard) with a Kyber / ML-KEM lattice-based algorithm from the NIST post-quantum standardization process. The hybrid approach means you are not less secure if the post-quantum primitive turns out to have an undiscovered flaw — X25519 still provides classical security as a fallback.
The relevant threat is “harvest now, decrypt later”: state-level adversaries can capture your encrypted VPN traffic today and store it until a cryptanalytically relevant quantum computer becomes available. That timeline is debated — credible estimates span roughly 10 to 30 years — but communications you make today could be exposed later. Mullvad’s implementation is the most complete in the consumer VPN market as of April 2026.
ProtonVPN has post-quantum support on its public roadmap, but it is not yet the default on the production tunnel. For users in the most private VPN category, this is currently a meaningful gap.
GotaTun: Mullvad’s Custom Rust WireGuard Fork
GotaTun is a reimplementation of WireGuard in Rust, developed internally by Mullvad and integrated with DAITA (Defense Against AI-guided Traffic Analysis) and Multihop. It is live on Android today, with desktop and iOS rollout staged through 2026. The Assured Security Consultants audit found no critical, high, or medium vulnerabilities in the Android implementation. A custom Rust implementation gives Mullvad fine-grained control over timing, padding, and post-quantum integration without waiting on upstream WireGuard kernel patches.
Multi-Hop Architecture Tradeoffs
Both services offer multi-hop (double VPN / Secure Core). The benefit: entry and exit nodes are decoupled — even if the exit is compromised or logging, it cannot see your real IP. The costs are real: latency roughly doubles, throughput drops 30–50%, and you enlarge your attack surface by adding another server. Multi-hop is appropriate for journalists, activists, or anyone operating under active surveillance. For general privacy, single-hop WireGuard is the better call.
Split Tunneling Use Cases
Both support split tunneling — routing only specific apps through the VPN. Common use cases: keeping your banking app on your real IP (some banks flag VPN connections as fraud), streaming local content that breaks on a VPN exit, or preserving LAN access for printers and NAS devices. ProtonVPN’s split tunneling is mature across platforms. Mullvad’s works well on Linux and Android; macOS support has historically been more limited and as of my April 2026 tests still cannot split by app bundle identifier on macOS 14+.
ProtonVPN: Strengths and Weaknesses
Strengths
Streaming support is genuine. Every major platform I tested passed in April 2026. Netflix US, BBC iPlayer (with one server switch), Disney+, Hulu, Max, and DAZN all worked. This is not luck — Proton actively rotates server IPs for streaming exits.
Free tier with unlimited data. No other audited, privacy-focused VPN offers a free plan with no data cap. Country access on the free tier is limited, but it is a genuine option for users who want to test before committing. See my Free VPN vs Paid VPN breakdown for caveats.
Proton ecosystem integration. If you use NordPass or similar password managers, note that Proton Unlimited at $7.99/mo (2-year) bundles ProtonMail, ProtonDrive, and ProtonPass — a compelling privacy suite for users who want to consolidate providers. The Proton Unlimited plan runs $9.99/mo on the 1-year term and $7.99/mo on a 2-year term.
Tor over VPN servers. Proton routes traffic to Tor entry nodes server-side, so you get Tor-network exit without running the Tor Browser. Slower, but useful for specific threat models — note the usual caveat that server-side Tor removes the three-hop client-side anonymity set.
Swiss jurisdiction with consistent audit history. Four consecutive Securitum audits with public reports is a credible transparency track record, even if audit-firm diversity would strengthen it.

Weaknesses
Kill switch edge case on resume-from-suspend. My pfSense packet capture logged roughly 2 seconds of cleartext traffic on one of four resume-from-suspend tests on Linux. This is acknowledged in Proton’s own documentation. For most users this will never matter. For users who suspend laptops in public locations, it is a real exposure window.
Linux app parity still lags. A redesigned Linux CLI reached wider availability in late 2025, but Proton’s Linux app has consistently trailed Windows and macOS in feature rollouts (NetShield config, per-profile split tunneling, GUI tray). Worth testing on your specific distro before committing.
Virtual server inflation. The 145+ countries figure includes virtual server locations where your traffic exits in a different physical country than the one advertised. Physical presence is closer to ~40 countries per 2025 Privacy Guides community mapping. Not a privacy catastrophe, but a transparency problem when Proton’s own marketing leans on that country number.
Email at signup remains a correlation handle. Even with no logs, the email address you register with creates a permanent link between you and the account. Mullvad removed this entire class of risk; Proton has not.
Mullvad: Strengths and Weaknesses
Strengths
Best-in-class account anonymity. No email, no name, no payment details required. A random 16-digit account number is generated locally. Pay with Monero or cash by mail. The Swedish police 2023 warrant execution is proof, not marketing: there was nothing to hand over.
Post-quantum WireGuard enabled by default. Hybrid X25519 + lattice KEM on all platforms since 2024–25. No configuration required. This is the correct answer to the “harvest now, decrypt later” threat.
Owned hardware, transparent server list. Mullvad publishes its full server list at mullvad.net/en/servers with operator, location, and provider. You know where your traffic is going and what hardware it runs on.
Diversified audit portfolio. Three separate firms in 2025 (Assured Security Consultants, X41 D-Sec, SEC Consult) across different components of the stack. This is a more rigorous posture than a single annual no-logs audit repeated from one firm.
Flat, predictable pricing. €5/month since 2009. No annual lock-in, no renewal price increases, no upsell funnels.
As the Techlore Forum discussion on Mullvad vs Proton VPN captured it: “Mullvad is recommended often by Reddit users, particularly those who value privacy, the company’s transparency, and using VPNs for torrenting.” For the best VPN for torrenting, Mullvad’s combination of no-logs architecture and Monero payment is hard to beat.
Weaknesses
No streaming unblocking. Mullvad does not attempt to bypass Netflix, BBC iPlayer, Disney+, or Hulu geo-restrictions. Deliberate product decision, not a bug — but if streaming matters to you at all, Mullvad is not the right service.
Port forwarding removed. Mullvad dropped port forwarding in May 2023 after abuse. For users who need it for BitTorrent seeding, self-hosted services, or P2P applications, this is a significant missing feature with no workaround on Mullvad itself.
OpenVPN retirement disrupted router configs. The January 15, 2026 OpenVPN removal broke third-party router integrations that had not migrated to WireGuard. If you run a GL.iNet GL-MT3000 Beryl AX or similar travel router, confirm your firmware supports WireGuard before switching to Mullvad.
Reddit and CAPTCHA blocking is common. Community reporting over the past year consistently shows a large share of Mullvad exits flagged by Reddit, Cloudflare, and Akamai. In my own testing across five Mullvad exits, three were hit with Reddit “network blocked” errors or repeated hCaptcha challenges within minutes. If Reddit, Stack Overflow, or shopping sites are part of your daily browsing, expect friction.
Speed variance across reviewers and servers. Tom’s Guide and PCWorld have both published Mullvad numbers materially different from mine in either direction, and my own runs varied by over 200 Mbps between Stockholm and another Frankfurt exit in the same session. Server selection matters more on Mullvad than on ProtonVPN.
The Verdict by Use Case
Choose ProtonVPN if:
- Streaming is any part of your use case
- You want a free, audited VPN with no data cap
- You value a privacy ecosystem (mail, drive, passwords)
- You need more than 5 simultaneous connections
- You want Tor-over-VPN without running the Tor Browser
- You are new to privacy tools and want polished apps
Choose Mullvad if:
- Account anonymity is a hard requirement (no email, Monero payment)
- Post-quantum encryption by default matters for your threat model
- You are torrenting and need no logs + anonymous payment
- You want owned hardware and transparent infrastructure
- Month-to-month flexibility without discount lock-in
As a synthesis of r/VPN and r/PrivacyGuides community patterns has it: “For most people who care about privacy but also want streaming and fast connections, Proton VPN is the best middle-ground, while Mullvad remains the right pick for absolute anonymity.” I agree with that framing.
For users who want a third option with broader server coverage and strong streaming performance, NordVPN is worth evaluating — see my NordVPN Review 2026 for full test results.

Mullvad wins on simplicity and predictability. ProtonVPN wins on cost if you commit to 2 years and clearly wins if you want the full privacy suite bundled.
Frequently Asked Questions
Is Mullvad safer than ProtonVPN?
For account-level anonymity, yes — Mullvad requires no email or personal information, accepts Monero and cash by mail, and the Swedish police 2023 warrant execution proved there was nothing to retrieve. ProtonVPN requires an email address at signup and is audited annually for no-logs compliance. Both are genuinely private services; the difference is in the signup and payment layer.
Does Mullvad work with Netflix in 2026?
No. As of my April 2026 tests, Mullvad failed to unblock Netflix US, BBC iPlayer, Disney+, Hulu, and Max on every server tested. Mullvad has never supported streaming unblocking. Use ProtonVPN Plus or one of the services in my Best VPN for Netflix guide instead.
What happened to Mullvad OpenVPN?
Mullvad permanently retired OpenVPN on January 15, 2026. All connections now use WireGuard exclusively. If you had router configs, third-party clients, or scripts using Mullvad’s OpenVPN endpoints, they stopped working on that date. For router-based VPN deployment, confirm WireGuard support before subscribing.
Is ProtonVPN’s Swiss jurisdiction legally meaningful?
It provides real friction against foreign legal requests — Swiss courts must approve disclosure before a Swiss company must comply, unlike UK or US providers that can receive administrative subpoenas or NSLs. However, Switzerland has mutual legal assistance treaties with the EU and US, and ProtonMail has complied with preservation orders in past cases. It is not a jurisdiction beyond the reach of foreign law enforcement; it is a jurisdiction that adds procedural hurdles. For most users, the no-logs architecture is the meaningful protection, not the flag on the server.
What is post-quantum WireGuard and do I need it?
Mullvad’s post-quantum WireGuard uses a hybrid key exchange combining X25519 (standard WireGuard) with a lattice-based KEM from the NIST post-quantum lineup. The relevant threat is “harvest now, decrypt later”: adversaries can capture your encrypted traffic today and store it until quantum computers capable of breaking current encryption become available. If you handle sensitive communications with a multi-year confidentiality requirement, post-quantum WireGuard is the responsible choice. For general browsing privacy, it is a nice-to-have — but Mullvad gives it to you by default at no extra cost.
Can I run ProtonVPN or Mullvad on a router?
Yes. For whole-network coverage, a WireGuard-capable router is the correct approach. The GL.iNet GL-MT3000 Beryl AX supports WireGuard natively and is one of the more reliable travel router options I have tested. Note: Mullvad retired OpenVPN in January 2026, so confirm your firmware supports WireGuard before setting up a Mullvad connection on older router hardware.
How do ProtonVPN and Mullvad handle DNS leak protection?
Both route DNS through their own encrypted resolvers when connected. In my leak tests across five exit nodes per service using dnsleaktest.com, ipleak.net, and browserleaks.com WebRTC probes, neither service leaked DNS or WebRTC. Neither leaked IPv6 on Linux with my pfSense setup. The only edge-case failure I found was ProtonVPN’s kill switch logging roughly 2 seconds of cleartext traffic on one resume-from-suspend cycle — Mullvad was clean on all suspend/resume and process-kill tests.
