Protect your online security

Core security

Proton VPN has designed a unique and secure VPN service with the Secure Core architecture to provide defense against network-based attacks. This architecture safeguards your connection by directing your traffic through various servers before exiting the Proton network. This ensures that even a sophisticated adversary who monitors network traffic at the exit server cannot identify the actual IP address of Proton VPN users or associate their browsing activity with that IP.

The Secure Core servers are located in data centers that are fortified and secured in Switzerland, Iceland, and Sweden. These data centers are subject to robust privacy laws and operate on dedicated networks exclusively managed by Proton VPN.

NetShield (Ad-blocker)

NetShield is a security function that utilizes DNS filtering to safeguard you against malware, hinder advertisements, and stop website trackers from monitoring your online activity while you browse the internet.

Accelerator for VPN

Proton VPN offers a distinct technology called VPN Accelerator, which has the potential to enhance VPN speeds by more than 400%. This technology addresses the CPU limitations that hinder VPN protocol processing, utilizes advanced networking strategies to minimize latency, and improves VPN protocol efficiency by optimizing their code. As a result, VPN Accelerator can significantly boost the speed performance of your VPN connection. 

Stealth

Proton VPN’s Stealth protocol is distinctive in its ability to avoid detection and surpass most VPN blocking techniques and firewalls. Our mission is to advance freedom and invent new technologies to combat censorship globally, setting us apart from other VPN services. With our Alternative Routing technology, we reroute connections over alternative paths to bypass internet blocks. Additionally, our Stealth VPN protocol disguises VPN traffic as regular traffic, enabling access to otherwise restricted information and combating censorship.

Robust cryptography

We employ the strongest encryption available to safeguard your online connectivity. This entails encrypting all of your network traffic with AES-256, conducting key exchange with 4096-bit RSA, and utilizing HMAC with SHA384 for message authentication. 

Forward secrecy

Our encryption cipher suites have been meticulously chosen to exclusively incorporate those that possess impeccable forward secrecy. This ensures that any encrypted traffic you send cannot be intercepted and deciphered at a later time, even if the encryption key used in a subsequent session is compromised. Every time you establish a connection, a fresh encryption key is generated, guaranteeing that no key is ever employed for more than one session. 

Powerful protocols

We employ exclusively secure VPN protocols – OpenVPN, IKEv2, and WireGuard. ProtonVPN deliberately avoids using PPTP and L2TP/IPSec servers, despite their lower operational costs, to ensure the utmost protection for your VPN connection. With ProtonVPN, you can rest assured that your VPN tunnel is safeguarded by the most reliable protocol. 

In case you reside in a country with strict internet regulations, our distinctive Stealth VPN protocol empowers you to circumvent detection and overcome most internet censorship and VPN restrictions. 

Full-disk encryption

Despite the fact that there is almost no personally identifiable data stored on Proton VPN servers, they are all safeguarded by complete disk encryption. This measure ensures protection against resource-intensive man-in-the-middle attacks that can potentially be carried out by government entities. With full disk encryption, not only are server certificates secured, but all other configurations and software stored on an exit server as well. This means that even if a server is somehow compromised, any data stored on it would remain inaccessible to attackers.

Swiss privacy

Proton VPN not only boasts robust technical security but also enjoys formidable legal protection. Its headquarters being in Switzerland affords it the shield of the world’s most stringent privacy laws, and it is beyond the reach of the US and EU authorities. Unlike VPN providers located in countries that belong to the fourteen eyes alliance, Proton VPN cannot be compelled to compromise its users’ privacy.

Reliable

Using a reliable VPN is crucial, and we are proud to be among the few VPN providers that disclose the identity of the people running our service. Our team has an extensive background in security, having developed Proton Mail, the largest encrypted email service globally. Our team’s commitment to safeguarding online privacy is evident in our endeavors to challenge governments, raise public awareness, and train journalists. We have a long-standing history of advocating for online privacy and supporting the open-source community.

Open source

Proton VPN, established by a team of scientists from MIT and CERN, places a high value on transparency and peer review. Our applications are fully open source, allowing anyone to inspect our code. This level of transparency provides assurance that our apps function as intended and carry out only the tasks they were designed to perform. We have made the code for all our apps available on GitHub for review.

Personal Safety

Proton VPN has taken extensive measures to safeguard the security of its Secure Core servers. Our critical infrastructure in Switzerland is situated in a high-security data center outside Zurich, accessible only through biometric verification. Similarly, our Iceland infrastructure is located in a secure facility that was once a military base. Additionally, our servers in Sweden are housed in an underground data center. We ensure the security of our servers at the hardware level by transporting our own equipment to these locations.

No logbook policy

According to Swiss law, we are not required to retain any records of user connections, nor can we be compelled to perform targeted logging on individual users. This enables us to guarantee that your personal browsing history remains completely private and cannot be disclosed to any third party, regardless of the circumstances. Our no-logging policy is applicable to all our users, including those who use our VPN service for free.

DNS leakage prevention

In addition to safeguarding your browsing traffic, Proton VPN also secures your DNS queries. We achieve this by directing your DNS queries through the encrypted tunnel and eliminating the need for third-party DNS providers. This approach shields your browsing activity from being compromised by any leaks arising from DNS queries.

Termination switch and always-on VPN

The Proton VPN applications come equipped with two useful features: the Kill Switch and the Always-on VPN. The Kill Switch function stops all network traffic if you lose connection to the VPN server, while the Always-on VPN feature automatically reconnects you to a VPN server. These features are essential for safeguarding your privacy by preventing any accidental disclosure of your actual IP address in the event of a VPN server disconnection.

Tor over VPN

With Proton VPN, you can easily access Onion sites with just one click as our VPN servers support Tor. By routing all of your traffic through the Tor anonymity network, you can enjoy the convenience of browsing the internet anonymously.

Anonymity

To safeguard your privacy, we don’t need any personally identifying details to set up your Proton VPN account. By using an anonymous Proton Mail email address, you can register for our VPN service and browse the internet without revealing your identity.

Fast speed

To ensure peak performance, we exclusively employ high-speed servers at Proton VPN. Our servers boast a minimum bandwidth of 1 Gbps, while numerous ones utilize 10 Gbps connections. Consequently, despite employing robust encryption, Proton VPN delivers lightning-fast speeds.

Open source

Proton VPN, established by a team of scientists from MIT and CERN, places a high value on transparency and peer review. Our applications are fully open source, allowing anyone to inspect our code. This level of transparency provides assurance that our apps function as intended and carry out only the tasks they were designed to perform. We have made the code for all our apps available on GitHub for review.

Convenient to use

We recognize the significance of user-friendly security technology. To this end, our team has developed the Proton VPN apps with a straightforward and intuitive interface. You can easily browse the internet in complete privacy and anonymity with just one click. Moreover, customized connection profiles can be created to automatically secure your device each time you go online.
