In-Depth Proton VPN Review 2025
When it comes to privacy-focused VPN providers, Proton VPN has built a reputation that few can match. Created by the same team behind the renowned encrypted email service Proton Mail, this VPN service promises Swiss-grade security with absolute transparency. But how does it perform in everyday use?
We’ve put Proton VPN through comprehensive testing for four full weeks to evaluate everything from its speed and security to its streaming capabilities and ease of use. Here’s our complete analysis to help you decide if Proton VPN deserves your subscription in 2025.
Speed Performance
How Fast Is Proton VPN in 2025?
Speed is critical for any VPN service, and Proton VPN delivers strong performance through its VPN Accelerator technology – a combination of protocol optimizations and routing improvements that significantly boosts connection speeds.
US Server Speed Test Results:
| Connection | Download Speed | Upload Speed | Ping |
|---|---|---|---|
| Baseline (No VPN) | 500 Mbps | 50 Mbps | 5 ms |
| Proton VPN (Nearby Server) | 460 Mbps | 47 Mbps | 8 ms |
| Proton VPN (Cross-Country) | 405 Mbps | 44 Mbps | 70 ms |
| Proton VPN (International) | 340 Mbps | 41 Mbps | 125 ms |
| Proton VPN (Secure Core) | 290 Mbps | 38 Mbps | 150 ms |
These results show an impressive 92% retention of base speeds on nearby servers, which easily handles 4K streaming, video conferencing, and online gaming without any noticeable lag. Even on international connections, Proton VPN maintained 68% of our baseline speed, providing smooth performance for most online activities.
The Secure Core feature, which routes traffic through multiple servers for enhanced privacy, does impact speeds as expected, but still delivered usable performance for everyday browsing and HD streaming.
Protocol Performance Comparison
| Protocol | Average Speed Retention | Best Use Case |
|---|---|---|
| WireGuard | 85-92% | General use, streaming, gaming |
| OpenVPN (UDP) | 70-80% | Good balance of security/speed |
| OpenVPN (TCP) | 60-70% | Maximum reliability on unstable connections |
| IKEv2 | 75-85% | Mobile devices, network switching |
| Stealth (obfuscated) | 55-65% | Bypassing strict network restrictions |
WireGuard consistently delivered the best performance in our testing, while the Stealth protocol – designed to bypass VPN blocks in restrictive regions – worked effectively but with expected speed reductions.
Security and Privacy Features
Swiss-Grade Security and True Privacy
Proton VPN’s security credentials are impeccable:
- Encryption: AES-256 with 4096-bit RSA key exchange
- Kill Switch: Available on all platforms with customizable settings
- Leak Protection: No DNS, WebRTC, or IP leaks detected in extensive testing
- DNS Handling: Secure DNS with encrypted DNS queries
What sets Proton VPN apart are its advanced security features built by a team with deep expertise in privacy technology:
Secure Core Architecture
This unique multi-hop system routes traffic through privacy-friendly jurisdictions (Switzerland, Iceland, or Sweden) before reaching the final destination server. In our testing, this provided exceptional protection against network-based attacks and significantly reduced the risk of traffic correlation, particularly valuable for users with elevated privacy needs.
NetShield
Proton VPN’s integrated ad and malware blocker performed admirably in our tests, successfully blocking approximately 95% of ads across various websites and correctly identifying all malicious domains in our controlled tests. NetShield works at the DNS level, providing system-wide protection rather than just browser-based blocking.
Open-Source and Audited
Unlike most competitors, Proton VPN has made all its applications fully open-source, allowing independent verification of their security claims. The service regularly undergoes independent security audits, with results publicly published – a level of transparency that builds genuine trust. During our testing period, we verified the authenticity of their latest audit reports and examined the responsive security improvements implemented.
Privacy-Focused Jurisdiction
Based in Switzerland, Proton VPN benefits from some of the world’s strongest privacy laws. Their strict no-logs policy has been tested in court, with Swiss courts confirming they cannot be compelled to provide user data they don’t possess. This proven track record of protecting user privacy significantly elevates their credibility compared to VPNs with untested privacy claims.
Streaming and Unblocking Capabilities
Strong Performance Across Major Platforms
Proton VPN has significantly improved its streaming capabilities since our last review, now offering reliable access to major platforms:
| Streaming Service | Unblocking Success | Video Quality |
|---|---|---|
| Netflix US | ✓ (32/35 servers tested) | 4K HDR |
| Disney+ | ✓ (30/35 servers tested) | 4K |
| HBO Max | ✓ (31/35 servers tested) | 4K |
| Hulu | ✓ (29/35 servers tested) | 1080p |
| Amazon Prime Video | ✓ (27/35 servers tested) | 4K |
| BBC iPlayer | ✓ (28/35 servers tested) | 1080p |
| ESPN+ | ✓ (30/35 servers tested) | 1080p |
| Peacock | ✓ (29/35 servers tested) | 1080p |
The Plus and Unlimited plan servers consistently unblocked major streaming platforms throughout our testing period. While Proton VPN doesn’t offer dedicated streaming servers labeled for specific services like some competitors, their “Plus” servers are optimized for streaming and performed reliably in our tests.
The consistency of access was particularly noteworthy – throughout our month-long testing period, we rarely encountered blocks or interruptions, suggesting Proton VPN actively maintains their streaming capabilities against detection measures.
Smart DNS Equivalent
Proton VPN doesn’t offer a traditional Smart DNS feature, but their “Alternative Routing” technology helps bypass certain network restrictions and can work on devices that don’t support full VPN apps. We had mixed results using this approach on smart TVs and gaming consoles, with about 70% success in accessing US-based content.
Torrenting and P2P Support
Proton VPN fully supports P2P file sharing across many of their servers, clearly marked within the application. These P2P-optimized connections delivered solid performance in our testing:
- Average Download Speed: 43-46 MB/s (with a 500 Mbps connection)
- Port Forwarding: Not supported
- SOCKS5 Proxy: Not available
The automatic kill switch proved essential during our torrenting tests, immediately cutting internet access when the VPN connection dropped, ensuring our real IP address was never exposed. The combination of strong privacy practices and decent speeds makes Proton VPN a good choice for privacy-conscious torrent users, though the lack of port forwarding might impact seeding capabilities.
Server Network and Global Coverage
Strategic Network Distribution
While not the largest network in the industry, Proton VPN’s server fleet is strategically distributed:
- Total Servers: 2,900+
- Countries Covered: 65+
- US Server Locations: 15+ cities with 400+ servers
- Specialized Servers: P2P, Tor, Secure Core, 10 Gbps servers
Proton VPN owns and operates all their server infrastructure directly (no third-party rentals), which enhances security but limits the speed of network expansion. During our testing across multiple locations, server connections were consistently stable with average connection times of 4-6 seconds using the WireGuard protocol.
The 10 Gbps servers (available in major locations) provided noticeably better performance for bandwidth-intensive tasks, consistently delivering 5-10% better speeds than standard servers during our testing.
User Experience and Interface
Clean, Informative Design
Proton VPN offers well-designed applications for all major platforms:
- Windows, macOS, Linux
- iOS, Android
- Android TV
- Chrome OS
- Browser extensions for Chrome and Firefox
The desktop interface stands out with its intuitive map-based design combined with a server list that provides useful information like server load and special features. The main dashboard clearly displays your connection status, IP address, and available security features.
Ease of Use
Proton VPN balances advanced features with user-friendly design:
- Quick Connect: One-click optimal server selection
- Profiles: Save customized connections for specific uses
- Server Sorting: Filter by country, features, or load
- Advanced Settings: Logically organized with helpful explanations
Our testing group, including several VPN novices, found Proton VPN relatively easy to use despite its advanced feature set. The clear visual indicators for server specializations (P2P, Tor, streaming optimization) were particularly helpful for users selecting servers for specific activities.
Unique Features
Tor Over VPN Integration
Proton VPN offers direct integration with the Tor network through specialized servers. This allows you to access .onion sites and benefit from Tor’s anonymity directly through the VPN application. In our testing, while this connection method was approximately 60-70% slower than standard servers, it provided a much more accessible way to use Tor for users concerned about privacy.
Free Plan With No Data Limits
Unlike most VPN providers, Proton VPN offers a genuinely useful free tier with:
- No data caps or bandwidth limits
- Servers in 3 countries (US, Netherlands, Japan)
- Medium speeds suitable for browsing and standard definition streaming
- Strong security and privacy protections
During our testing, the free servers maintained about 65-75% of the speed of Plus servers – significantly better than most limited free VPN offerings and without the privacy compromises often found in free VPNs.
Alternate Routing
This technology helps bypass certain types of VPN blocks by using different connection methods when standard connections fail. We tested this successfully in several environments where standard VPN connections were being interfered with, including university networks and public Wi-Fi systems with VPN restrictions.
Mobile Apps
Proton VPN’s mobile experience maintains most functionality of the desktop applications while adapting to mobile interfaces:
Android App Highlights:
- Split tunneling functionality
- NetShield ad and malware blocking
- Always-on VPN capability
- Dark and light modes
- Secure Core servers access
iOS App Highlights:
- Intuitive map interface

Frequently Asked Questions
Find quick answers to common questions about Proton VPN — how it works, how to install it, and how it keeps your data private and secure. Whether you’re new to VPNs or need technical help, this section has you covered.
Yes, Proton VPN offers a genuinely free tier with no data limits or bandwidth caps. The free version gives access to servers in 3 countries with medium speeds. While the free tier doesn’t unblock streaming services, it provides solid security and privacy protection without the compromises typically found in free VPNs.
Proton VPN works in China through its Stealth protocol, though with variable reliability. This obfuscated connection disguises VPN traffic to bypass deep packet inspection. For users traveling to countries with heavy internet restrictions, we recommend downloading the app beforehand and testing the Stealth protocol settings.
Yes, Proton VPN is exceptionally safe. Created by scientists from CERN, it offers open-source applications that anyone can inspect, undergoes regular independent security audits, and operates under strict Swiss privacy laws. Their proven no-logs policy and secure infrastructure make them one of the most trustworthy VPN providers available.
Proton VPN allows up to 10 devices to be connected simultaneously with a Plus or Unlimited subscription. The free plan is limited to 1 connection at a time.
Yes, Proton VPN consistently unblocks Netflix libraries from various countries. In our tests, Plus servers had a 91% success rate in accessing US Netflix content, along with good performance accessing other regional libraries including UK, Canada, Japan, and Germany.
Proton VPN is excellent for torrenting with dedicated P2P-optimized servers, strong security features, automatic kill switch, and competitive speeds. Their strict no-logs policy and Swiss jurisdiction provide additional privacy protections for torrent users.
Both are excellent services with different strengths. NordVPN offers a larger server network, slightly better overall speeds, and more specialized features like dedicated IP addresses. Proton VPN provides superior privacy credentials with open-source applications, proven no-logs policy, and a useful free tier. Privacy-focused users will prefer Proton VPN, while those seeking maximum features may prefer NordVPN.
Proton VPN’s free tier is subsidized by paid subscribers. As part of the larger Proton privacy ecosystem (including Proton Mail, Calendar, and Drive), the company uses a freemium business model where limited free services attract users who may later upgrade to premium features. This approach allows them to provide free privacy tools without resorting to selling user data or showing ads.
When properly configured, Proton VPN connections cannot be effectively tracked. Their combination of strong encryption, leak protection, automatic kill switch, and optional Secure Core technology ensures your activities remain private from ISPs, websites, and other third parties. For maximum anonymity, their Tor integration provides additional layers of protection.
Like all VPNs, Proton VPN creates some overhead that affects internet speed. However, with their VPN Accelerator technology and the WireGuard protocol, the impact is minimal on nearby servers (typically only 8-15% reduction). Only when using advanced privacy features like Secure Core or Tor integration will you notice significant slowdowns. For everyday browsing, streaming, and downloading, the performance impact is negligible on modern connections.
