(2) Robust Safety and Encryption.

ProtonMail adds encryption to its privacy features by doing so for each email. ProtonMail has begun using PGP encryption in 2022 to protect emailed files and emails. The elliptic curve cryptography (ECC) was also added in April 2019, providing users with the advantages of increased security and speed.

Although technically included in the aforementioned advantages, this merits a separate note.
