ProtonMail ( Safeguarding your privacy in the digital era


In today’s interconnected world, concerns about privacy and security are at an all-time high. With cyber threats looming large and data breaches becoming increasingly common, it’s imperative to choose email providers that prioritize user privacy and data protection. Among the array of options available, ProtonMail stands out as a beacon of trustworthiness and security. Let’s delve into why ProtonMail is considered safe, how it works, and the risks associated with using it.

Why ProtonMail is safe

  1. End-to-End encryption
    ProtonMail employs end-to-end encryption, which means that only the sender and the recipient can read the emails. This ensures that even ProtonMail itself cannot access the contents of your emails.
  2. Zero-Access encryption
    ProtonMail utilizes zero-access encryption, implying that all user data stored on ProtonMail servers is encrypted before it reaches their servers. As a result, even if ProtonMail’s servers were compromised, the data would be incomprehensible to any unauthorized party.
  3. Swiss privacy laws
    ProtonMail is based in Switzerland, known for its stringent privacy laws and neutrality. These laws provide an additional layer of protection for user data, making it more challenging for governments or other entities to gain access to personal information.
  4. Open source
    ProtonMail’s codebase is open source, allowing experts to scrutinize its security measures and identify any potential vulnerabilities. This transparency fosters trust among users and the broader cybersecurity community.
  5. Two-Factor Authentication (2FA)
    ProtonMail offers two-factor authentication, adding an extra layer of security by requiring users to provide a second form of verification, such as a code sent to their mobile device, in addition to their password.

How ProtonMail works
ProtonMail operates on the principle of simplicity without compromising security. Here’s how it works:

  1. User registration
    Users sign up for a ProtonMail account using an email address and password. Optionally, they can use an alias to further protect their identity.
  2. Encryption key generation
    Upon registration, ProtonMail generates a pair of encryption keys: a public key and a private key. The public key is used to encrypt messages, while the private key, which is never shared with ProtonMail, is required to decrypt them.
  3. Sending encrypted emails
    When a user sends an email, ProtonMail encrypts it using the recipient’s public key, ensuring that only the intended recipient can decrypt and read the message.
  4. Receiving encrypted emails
    Similarly, when a user receives an encrypted email, ProtonMail uses their private key to decrypt the message, ensuring that only they can access its contents.

Where Email data is stored
ProtonMail stores user data on servers located in Switzerland, under the jurisdiction of Swiss privacy laws. All data stored on these servers is encrypted with zero-access encryption, meaning that even ProtonMail employees cannot access it without the user’s decryption key. This decentralized approach to data storage enhances security and mitigates the risk of data breaches.

Risks associated with ProtonMail
While ProtonMail offers robust security features, no system is entirely risk-free. Some potential risks associated with using ProtonMail include:

  1. Phishing attacks
    Users may still be susceptible to phishing attacks, where malicious actors attempt to deceive them into revealing sensitive information such as passwords or encryption keys.
  2. Loss of decryption key
    If users lose their decryption key or forget their password, they may permanently lose access to their encrypted emails, as ProtonMail does not have access to this information.
  3. Metadata exposure
    While ProtonMail encrypts the content of emails, metadata such as sender and recipient information is still visible. Users should be mindful of this when communicating sensitive information.

In conclusion, ProtonMail is a leading choice for individuals and organizations seeking to safeguard their privacy in an increasingly digital world. With its end-to-end encryption, zero-access encryption, and commitment to transparency, ProtonMail provides users with peace of mind knowing that their email communications are secure and protected. However, users should remain vigilant against potential risks and adopt best practices for ensuring their online security.

ProtonMail complied with nearly six thousand government requests for user data last year, marking a thousand more than in 2021. This record figure is notable as ProtonMail aims to distinguish itself with clear privacy assurances and stringent Swiss legislation.

These figures are disclosed in Proton’s annual transparency report. In 2022, ProtonMail received almost seven thousand official government requests for user data (metadata). Over a thousand requests were rejected, while the remaining 5957 were granted. In 2021, ProtonMail received over six thousand requests, with 4920 being granted. In 2020, the figures stood at over 3700 requests submitted and 3000 granted.

In response to Restoreprivacy, Proton stated that the increase in the number of requests was “not surprising” due to the service’s growing user base. Over a hundred million people now use one or more Proton services, typically drawn to Proton for its focus on anonymity and strict Swiss legislation. Government requests for user data must also go through Swiss legal channels. If Swiss law is violated, Proton must surrender user data to the Swiss government, which may then pass on the information to the requesting government. Proton can only provide metadata, as the content of emails, attachments, and other information is always encrypted and therefore unreadable, even by Proton, the company emphasizes.

The American FBI is among the government agencies that have requested – and received – user data from Proton. With the help of metadata, the FBI was able to locate an American ProtonMail user who was being investigated for threatening an employee involved in the presidential elections. Forbes reports this in a reconstruction, also indicating that no government charges have been filed against the ProtonMail user in question.
