Why Encrypt Email?

Before diving into the specifics of encrypting email in Outlook 365, let’s first understand why email encryption is important.

• Protection against Data Breaches: Email encryption adds an extra layer of security, reducing the risk of data breaches and unauthorized access to sensitive information.
• Compliance with Regulations: Many industries, such as healthcare and finance, have strict regulations regarding the protection of sensitive data. Encrypting email helps organizations comply with these regulations.
• Building Trust: Encrypting email demonstrates a commitment to data security, enhancing trust between senders and recipients.
