Proton AG

Proton AG is a Swiss security-software company whose portfolio turns the same end-to-end encryption and zero-knowledge architecture that made Proton Mail famous into a complete privacy ecosystem. Its six Windows titles cover the everyday data-protection cycle: Proton VPN supplies a high-speed, no-log tunnel for safe public-Wi-Fi browsing, streaming, or torrenting; Proton Drive adds encrypted cloud storage that lets users sync, share, and collaborate without exposing files to third-party scanning; Proton Pass stores, generates, and autofills passwords, credit cards, and notes inside an open-source vault that even the vendor cannot read; Proton Mail gives each account a @proton.me address protected by PGP-grade cryptography and Swiss privacy law, while Proton Mail Bridge lets desktop clients such as Outlook or Thunderbird talk to that service over IMAP/SMTP without losing encryption; finally, Proton Authenticator generates time-based and push 2FA codes to harden logins for any online service. Together the suite addresses personal, freelance, and small-business needs—securing remote work, shielding journalists and activists, or simply helping households keep credentials and correspondence away from advertisers and breaches. All six applications are available free of charge on get.nero.com, where they are delivered through trusted Windows package managers like winget, always fetch the newest release, and can be installed individually or in a single batch.
