Proton AG

Proton AG is a Swiss security-software company whose entire portfolio is built around the principle of default end-to-end encryption and zero-access architecture. Its lineup covers the everyday digital life cycle: Proton Mail supplies web and mobile email that keeps message bodies and attachments encrypted even from the service provider; Proton Mail Bridge extends that protection into familiar desktop clients such as Outlook and Thunderbird. Proton VPN wraps all outbound traffic in AES-256 tunnels, offering NetShield ad-blocking, Secure Core routing through privacy-friendly jurisdictions, and an always-on kill switch for travellers or public-Wi-Fi users. Proton Drive synchronizes folders and files with client-side encryption, letting teams share annotated documents without exposing plaintext to the cloud. Proton Pass stores, generates and autofills credentials, credit-card numbers and notes inside an open-source vault that supports hide-my-email aliases. Proton Authenticator generates time-based and push-based 2FA codes that can be backed up with the same zero-knowledge recovery keys. Finally, Proton Meet supplies browser-based group video calls with E2EE, adjustable lobby controls and screen-sharing, making it an alternative to mainstream conferencing platforms for lawyers, physicians, journalists and remote staff who require confidentiality. Together the suite forms a privacy-centric workspace that replaces the conventional mix of separate email, VPN, cloud, password, authentication and meeting services. All seven Proton applications can be downloaded free of charge from get.nero.com, where installers are delivered through trusted Windows package sources such as winget, always pull the latest upstream release, and may be queued for batch installation.
