Industry Leading Security Features
Messages are stored on Proton Mail servers using end-to-end encryption at all times and are transmitted securely between Proton servers and user devices. This largely eliminates the risk of message interception.

Zero Access to Your Email Content
Proton Mail's zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that Proton does not have access to. This means we don't have the technical ability to decrypt your messages.

Open-Source Cryptography
Proton Mail's open-source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection. Proton Mail only uses secure implementations of AES, RSA, along with OpenPGP, while all of the cryptographic libraries used are open source. By using open-source libraries, Proton Mail can guarantee that the encryption algorithms used do not have clandestinely built-in back doors.

Proton Mail in the press:
“Proton Mail is a Gmail-like email system which uses end-to-end encryption, making it impossible for outside parties to monitor.” Forbes

“A new email service being developed by a group who met at MIT and CERN promises to bring secure, encrypted email to the masses and keep sensitive information away from prying eyes.” Huffington Post

Update review

In comparison to Tuta Mail, Proton is much more secure because in the event of your pass phrase get stolen or you misplaced it, you can always regenerate a new one and it will disable the old one. I could not do this with Tuta Mail because the pass phrase generated at creating your account cannot be changed later, that means your Tuta Mail account can be taken over or hijacked by anyone learning about your original Tuta Mail pass phrase. For those who don’t understand pass phase is the decryption key to all your data, it’s not stored on the service provider’s server. It’s generated using client side technology to guarantee only the user can decrypt their data, it’s the same case with cryptocurrencies like Bitcoin. If you lose the decryption or private key, all your data is gone or Bitcoin is gone. You must take self responsibility for your own data. I think this is very powerful, it definitely empowers people. Without self-responsibility, people will always be a slave to big tech and don’t complain if big tech harvesting your data for advertising or training their AI or who knows what they do with it behind the scene (like manipulating the search algorithm or influencing people’s opinion especially during election) to enrich themselves and putting you the internet users at risk of data breach to malicious hackers.

Great mail app for privacy focused individuals

This application gets a lot of things right. The service blocking trackers is a wonderful future that is welcomed for someone like me who values their privacy. There are some things that the app is missing that I hope there are added in the future. The ability to choose which maps opens when you click on an address would be great. Also being able to add an email address from a third-party service through the application would be wonderful as well, instead of having to go through the website on a browser to add the email. I do also wish that there were more customization options for the layout of the app. As well as selection of colors. I like that there is a dark mode however, I wish there was an actual dark mode option for OLED screens. these are more of quality of life improvements than things that are needed in the app however, I think that the app itself and the functions and services are provides are more than adequate and definitely worth the price.

EDIT: Apparently you can a third party email to this service, but only if you’re paying for a business account… If you’re paying a premium for this service that should come as a given, not something locked behind a larger paywall.

In the end encryption is vital to our basic human rights

Isn’t combat reaching everyone of us to utilize some form of end and encryption in our communications very much like governments due. When companies begin to read and index emails easily because of the PGP protocols it makes hacking seamless for nefarious actors as well as governments looking to monitor individual citizens in order to target. Therefore proton mail offers an excellent source I’ll be at a pricey cost. It is important to note that another email provider Nonnas to do note provides even more robust encryption as the email address and your subject line are encrypted. They are free service offers similar options as proton mail but far less expensive cost. They are also in the EU with much more stringent privacy standards. Neither one of these platforms are subject to US search warrants. But note it is far more important to encrypt your email address so that you can’t be targeted in the subject line is an equally important tap task to be encrypted. The downside is the GUI is poor very poor. Proton mail offers a nice GY that integrates with the devices very nicely. All in all when comparing email platforms the only other platform I’ve seen that measures up to these two is start Mail.
