WHAT IS PERFECT FORWARD SECRECY?

Perfect forward secrecy refers to how an encryption algorithm generates
encryption keys and ensures that a unique set of keys are used for each VPN
session. These keys are used to encrypt your VPN connection so that no one can
monitor your activity. We only use VPN protocols and encryption that support
perfect forward secrecy.


HOW DOES PFS WORK?

We exclusively use encryption and VPN protocols that support perfect forward
secrecy. Each time you connect to Proton VPN, we generate a new encryption key,
to provide you with a more secure VPN connection.


PROTECT PAST ACTIVITY

By never re-using old encryption keys, we ensure that your traffic cannot be
captured and decrypted later if an encryption key from a future VPN session is
somehow compromised.


IMPROVED SECURITY

Perfect forward secrecy gives you improved security. In contrast, if all
browsing data is encrypted with a single private key, that key can be stolen and
used to access all your past activity. With PFS, all your activities stay
private, even if there is a leak.


ADVANCED PRIVACY FROM PROTON VPN


SECURE CORE VPN

Our Secure Core network is made up of physical servers that we own, located in
countries with very strong privacy laws. We route your connection through a
second VPN server for extra security. You can connect to our Secure Core network
with a Proton VPN Plus plan.


DNS LEAK PROTECTION

We prevent DNS leaks that can expose your browsing history by encrypting your
DNS requests in our VPN tunnel and resolving them using our own DNS servers.
When you are connected to Proton VPN, nobody can access your DNS requests.


PRIVATE SIGN UP

When you sign up for a Proton VPN account, you don’t need to provide us with any
identifying information before connecting, just an email address. Once you sign
in you can start browsing securely with just one click.


HOW PROTON VPN PROTECTS YOU ONLINE


BASED IN SWITZERLAND

We’re based in Switzerland, which has very strict privacy laws and is free from
EU and US mass surveillance practices.


TRUSTED

Proton is supported by the European Commission and recommended by the UN as a
way to bypass censorship.


VPN ACCELERATOR

Free and available to everyone who uses Proton VPN, our unique VPN Accelerator
technology can improve speeds by over 400%.


OPEN SOURCE

We’ve made all our apps open source, so anyone can inspect their code. We have
also published the audit reports from independent security experts on our
website.


KILL SWITCH

If you unexpectedly lose connection to your Proton VPN server, our kill switch
will ensure your unique IP address is kept private.


NO-LOGS VPN

We operate a strict no-logs policy, so we cannot be forced to share any
information about your online activity with anyone.


SECURE VPN PROTOCOLS

The VPN protocols we use are known to be secure — IKEv2, OpenVPN, and WireGuard.
We don’t use less secure protocols, even if they are less costly to operate.


FULL-DISK ENCRYPTION

All our servers are protected by full-disk encryption, meaning that even if our
servers were physically seized, it would not be possible to intercept user
traffic.

VEELGESTELDE VRAGEN


WHAT IS PERFECT FORWARD SECRECY?

Perfect forward secrecy is achieved by creating a unique set of encryption keys
for each Proton VPN session. This is done by generating new keys each time you
connect to one of our VPN servers using secret numbers and robust mathematical
procedures. This means that if your private key for one session is compromised,
it cannot be used to decrypt any past (or future) browsing sessions.


WHY SHOULD I USE PERFECT FORWARD SECRECY?

If a hacker managed to get hold of one of the keys for a single session that
used perfect forward secrecy, they could only use it to access data from that
specific session, while the data in the rest of your sessions would remain safe
(since different unique keys were used to encrypt and protect them). It also
means that your session key will remain secure even if your VPN’s private key
was exposed.

All Proton VPN connections are protected by perfect forward secrecy.


HOW DOES PROTON VPN USE PERFECT FORWARD SECRECY?

By using any of the Proton VPN apps, you will automatically be protected by
perfect forward secrecy, as we only use encryption that supports it. Get Proton
VPN to start browsing with perfect forward secrecy, you don’t need to take any
additional steps.


WHAT VPN PROTOCOLS DOES PROTON VPN USE?

We use the OpenVPN, IKEv2, and WireGuard VPN protocols, which are known to be
secure. We don’t support any VPN connections using PPTP or L2TP/IPSec (even
though they are often cheaper and easier to run), as they do not meet our
security standards. This is true for both free and paid Proton VPN plans.
