Proton VPN vs. Proton Authenticator

Strengthen your organization's security posture and simplify compliance with major regulatory standards like ISO 27001, GDPR, and HIPAA using Proton's software-based VPN solution. Designed for easy and seamless integration with your existing infrastructure, Proton VPN for Business provides a flexible and scalable way to protect your organization. All our plans use strong encryption algorithms such AES-256 or ChaCha20 to keep your data secure in transit. You can further enhance your company's endpoint security with enforced two-factor authentication (2FA) and effortless single sign-on (SSO) user access. And with full support for SCIM, you can seamlessly automate provisioning and user management across your organization. With the Proton VPN Professional plan, you can assign dedicated VPN servers and Gateways (logical groupings of dedicated servers), and segment access based on each individual's role or department to ensure employees only connect to the resources they need. This approach enhances both security and operational efficiency across distributed teams and hybrid environments. Proton VPN is part of a suite of open source end-to-end encrypted tools created by the team behind Proton Mail. Backed by a large global server network, our platform delivers high-speed (up to 10 Gbps) connections and trustworthy privacy protection, making it ideal for businesses of all sizes that prioritize data security and compliance.

Proton Authenticator is a privacy-focused two-factor authentication app that generates time-based one-time passwords, thus providing an additional layer of security to online accounts beyond standard passwords and allowing users to protect their accounts across various devices. As an open-source application that uses end-to-end encryption, it guarantees that all cryptographic operations and secret keys are processed locally, meaning that even Proton's developers cannot access users' unencrypted 2FA data, thereby emphasizing a commitment to transparency and strong privacy by design. Users can synchronize their 2FA codes across multiple devices through encrypted backups, utilizing options such as iCloud or a Proton Account, while also having the capability to import codes from other authenticator apps and export them when needed, which grants them flexibility and control over their 2FA credentials without being locked into a single provider. In addition, Proton Authenticator is entirely free, with no advertisements or tracking, and features secure options like biometric locks and offline access, allowing users to generate login codes at any time, even without an internet connection. This makes it particularly appealing for individuals who prioritize security while efficiently managing their online accounts, as it combines usability with robust protective measures. Furthermore, its commitment to user privacy and transparency sets it apart in a market where many alternatives may compromise these values.
