Any email should be hacker-proof, and most of today's services meet security standards - but not enough. ProtonMail is a project of top information security experts from Harvard and the University of Massachusetts. The creator of the service claims that there is no more reliable and convenient mail and he is mostly right - this is a really great mail, which has a high level of protection and advanced functionality.
But the main difference between ProtonMail is not the protection. Much more important is the advantage that the mail servers (at least the main ones, where the most important data is stored) are located in Switzerland. Since the territory of this state is a neutral zone, all companies located there have the same rights - that is, they may not be subject to the laws of other countries and most international ones.
If you need a post office for work, this is a great option. It takes no more effort to register an account with it than with any other mail, and the level of user comfort and security will increase dramatically. Most of the features that ProtonMail offers are free.
Advantages of the service:
There are some disadvantages, such as paid accounts. To get the full functionality of the service, you must pay $24 per month. This is not much for business - it fully pays off with convenience, but will be a problem for private use.
Not only will you, but all those who work with you, will be assured of the security of the service. ProtonMail offers a paid feature - a personal unique encryption key that you can send to your recipients along with emails to confirm your identity. This will allow you to work with processes that would necessarily be conducted in a face-to-face meeting if you were using regular mail.
You should try ProtonMail if you:
Use ProtonMail for business and ensure your security and privacy - your data is securely protected by the best of the best.
