Proton Mail features: What can you do with it?

Proton Mail is a secure email platform that offers a comprehensive suite of features designed to protect your privacy and data. From end-to-end encryption to advanced tracking protection, each feature is meticulously crafted to provide an unparalleled level of security.

End-to-End Encryption

End-to-End Encryption

End-to-end encryption ensures that your email content is encrypted on your device before it is sent to Proton Mail servers. This encryption is automatic and doesn’t require any special software or technical skills.

Only you and your intended recipient have the ability to decrypt and read the email, making it secure against unauthorized access.

Zero-Access Encryption

In zero-access encryption, even Proton Mail cannot access your emails. When you receive emails from other service providers, they are instantly encrypted on Proton Mail servers using your public key.

This architecture ensures that Proton Mail does not have the technical capability to decrypt your messages.

Password-Protected Emails

This feature allows you to send secure emails to people who don’t use the platform. Before sending the email, you can select a password in the composer. The email will then be encrypted and can only be accessed by someone who has the password, ensuring additional security.

Two-Factor Authentication with Hardware Security Keys

Two-factor authentication (2FA) with hardware security keys like YubiKey provides an additional layer of security. These physical keys are immune to online phishing attacks, and they eliminate the need to use an authenticator app on your phone.

Proton Mail security

Enhanced Tracking Protection

Proton Mail automatically blocks tracking pixels and hides your IP address when you read emails. This prevents advertisers from building a profile on you or serving you ads based on your email activity.

Proton Sentinel Program

This is an account protection program designed for high-risk individuals like journalists and activists. It uses AI systems and human specialists to monitor for malicious activities and security threats, providing an extra layer of security.

Open Source and Audited

Proton Mail open source

All Proton Mail’s apps are open source, allowing anyone to inspect, use, and improve them. They have also been independently audited by third-party security experts, and the results are publicly available, ensuring transparency and trust.

Hardware-Level Security

Proton Mail owns its server hardware located in Switzerland. These data centers are highly secure and require biometric access. The servers use fully encrypted hard disks with multiple password layers, adding an extra layer of security.

Built-in PGP Support

Proton Mail supports Pretty Good Privacy (PGP), allowing you to send end-to-end encrypted emails even to non-Proton Mail users. This feature automatically encrypts messages using the recipient’s public key.

Address Verification and Key Pinning

Address verification and key pinning are features that perform client-side verification of encryption keys. This adds an optional control layer over key management and protects against man-in-the-middle attacks.

Proton Mail privacy

PhishGuard and Link Protection

PhishGuard is designed to protect against phishing attacks, while link protection ensures that malicious links are flagged. These features add several layers of defense against social engineering attacks and human error.

Onion Address and Alternative Routing

Proton Mail offers an Onion address for access over the Tor network, providing an extra layer of anonymity. The alternative routing feature helps you access your email even if Proton Mail is blocked by your government.

Community Contributions

Proton Mail is actively involved in the security community. They maintain the world’s most widely used open-source OpenPGP library and offer a bug bounty program to encourage security researchers to find and report vulnerabilities.
