Email Security: It is possible to automatically encrypt data with Microsoft 365. The process does not require any configuration on your part to do so. You can accomplish this without 3rd party assistance. This is a big selling point in the suite of services offered. In the early days of the Internet, the TLS (Transport Layer Security) protocol was a revolutionary technology. Today, TLS has become one of the most critical protocols for processing data.
The security of email within your organization is essential (and it must be kept secure because, if hacked, it could have disastrous consequences). As part of Microsoft 365’s ecosystem, you have a few extra encryption options. There is no need to use third-party services to enable these more advanced security protocols. However, companies that wish to receive extra support do so can also do so.
Encrypt Emails with Microsoft 365
The Office 365 Message Encryption Protocol (OME), which is part of Microsoft 365, makes sending emails to clients and external parties safe and easy. In order to ensure the security of emails sent to recipients, users can use strong encryption regardless of which email provider they employ. OME works with most email providers ranging from giants like gmail to smaller email providers.
Users log in through a web portal using credentials or one-time passwords to access a portal where administrators define transport rules. Emails containing confidential information are delivered as HTML files. To be able to do this you do not need to have any special software installed.
IRM (Information Rights Management)
IRM is a next-level security protocol, it also prevents confidential company emails from being forwarded or printed.
Email SEcurity: S/MIME, or Secure/Multipurpose Internet Mail Extensions
Is a method of encryption that utilizes both a public and private key, thus making the contents of emails accessible to only the intended recipient.
There are advantages to using Advanced Email Encryption Options with Microsoft 365.
Microsoft 365 offers different encryption options. These options all have different purposes. If direct information about a patient or client must be sent to a third party, then OME is recommended. There is no requirement for recipients to use a Microsoft 365 account with this protocol. As recipients forward or copy confidential information, IRM prevents it from leaking. Most commonly, S/MIME is uinformation. with government agencies, as well as extremely sensitive information.
This type of encryption requires the expertise of a skilled administrator. However, adding this layer of security has its advantages. This layer of encryption is almost bullet proof. Keep in mind that encryption is as strong as its users, so training people is a key factor in security success.

Which Settings Should I Enable for Secure Business Email?
The use of multifactor authentication, or MFA, will further protect the confidentiality of company emails. As an alternative to 2FA text messages, Microsoft 365 pairs wonderfully with Yubikeys, which provide more security than hardware tokens like Yubikeys.
In addition to mailbox audit logging, enable DKIM, SPF, and DMARC . Disable automatic forwarding and the options for POP3 and IMAP4 . The most significant step is to provide regular training on security issues. Since no encryption option is impossible to crack by itself, and human error will always present a threat if employees do not receive regular training.
