What Is a Digital Signature?Ī digital signature is a unique identifier that validates the authenticity of a person’s outgoing email messages and assures recipients they have come from that person, as opposed to a cybercriminal or unknown sender. One of the most effective lines of defense is the digital signature, which combines identity algorithms, traceability and encryption to improve email security for all users, no matter their level of tech-savviness. Even as enterprise email fraud becomes a bigger threat, Outlook continues to evolve its data security features.
Microsoft Outlook is one of the world’s most popular email services, with more than 400 million active users as of 2018.
