Your data, your rules

Usamos o Proton Mail em nossa clínica de imagens médicas. A migração de nossos servidores auto-hospedados foi perfeita e nossa equipe adora a simplicidade de enviar e receber relatórios de pacientes de nossos parceiros.

Antes, tínhamos uma conta do Google que depois foi transferida para o Outlook. Problemas eram constantes e queríamos mais segurança para os dados e as comunicações de nossos advogados e clientes. O Proton Mail facilita isso. Simplesmente funciona.

I have just started an engineering consulting business. Being a startup, I am somewhat sensitive to price but I don&#39;t expect email to be a major expense. I simply need it to work. My plans and contracts get delivered to my clients. I also need access on both my computer and phone. With Proton Mail, I get all of that and the security is a bonus.

Our old self-hosted email server got infected by a virus. The virus opened the Outlook files and stole all the emails and addresses. Then all of our members started getting spam from our email server — that was pretty terrible. With Proton, we get a very important feature: inboxes that are encrypted and more secure than services like Google. We were lucky that we onboarded with Proton right before the pandemic in 2020 so we could easily scale our usage.

[Proton Mail’s] encryption means I don&#39;t have to worry about my mail being read before it reaches the recipient. Other companies fail to respect my privacy.
