Security Features
When it comes to searching for the best VPN, robust security is of paramount importance. Our team has researched Proton and its security and privacy features. Below we summarize key features in our Proton VPN review.
Encryption Protocols
Proton VPN uses the top-of-the-line encryption protocol AES-256, along with exchanging keys using 4096-bit RSA. It uses HMAC and SHA384 to authenticate messages. Additionally, Proton generates a new encryption key every time you log onto the VPN. This “forward secrecy” strategy further protects data by preventing repeated use of the same encryption key.
Kill Switch
Even the best VPN will occasionally have connection issues. In the event that your Proton VPN becomes disconnected, the kill switch function will automatically block internet access to keep your data safe. Similarly, the Always-On feature automatically reconnects the VPN to a server to continue protection.
NetShield Ad-Blocker
One of the most important reasons to have a VPN is detection and protection from unwelcome third parties. That’s where Proton’s NetShield Ad-Blocker comes in. By filtering out malware, adware, and third-party web trackers, NetShield Ad-Blocker helps protect you from unwanted prying eyes. By preventing the loading of unwanted content, it helps prevent slowdowns and maintains speed.
No-Logs Policy
Proton has a no-logs policy for all subscribers, including free VPN users. It keeps no record of user activity, location, or other data. Since it is located in privacy-friendly Switzerland, Proton cannot be forced to share user data.

Once installed, Proton will connect to the fastest server available for your location. With a paid Proton account, you can change the server location to suit your internet needs.
Subscription Plans and Money-Back Guarantees
Users can choose from a variety of Proton VPN subscription plans, including Free, 1-month, 12-month, and 24-month. Proton may offer discounts to first-time aid subscribers, with the selected plan auto-renewing at the regular price. The shorter paid subscriptions cost more per month than the longer plans, with the monthly plan costing nearly three times as much per month as the 24-month plan. Proton also offers discounts for student users, helping students keep their sensitive information and internet activity secure.
Do you need some time to try Proton VPN before making a final decision? The we think you’ll like the fact that Proton offers a 30-day money-back guarantee. It’s important for you to feel comfortable with the VPN that you choose, and a 30-day guarantee lets you try all the features for an entire month. If you decide that Proton is not the right VPN for you, the company will refund your money if you let them know within 30 days after purchase.

Proton offers several modes of customer support. Members can access live chat, but the website does not specify whether it is available 24/7 or just during normal business hours. There is an extensive knowledge base, with user guides for a wide range of subjects. Whether you have a question about installation or billing, you can find answers in the online user guides.
There is also an online form that you can use to ask questions. The form is available on the Contact Us page, along with an email address if you prefer to send an email instead.
Open Source and Independently Audited
When it comes to securing your data and guarding your privacy, you want to be able to trust your VPN provider. For that reason, we’re impressed with the fact that Proton is an open-source VPN, which means that any third party can inspect its code. This policy of transparency ensures that Proton is providing the services it claims to provide, and nothing else. Proton regularly hires independent security experts for audits and publishes the results online.
