mitigate risks, associated with a number of threats (phishing emails, use of unreliable passwords,
installation of programs, etc.)

The second step is to deploy tools for protection of email services. Such software ensures protection
against external threats, for instance, NGFW helps to block potentially malicious network traffic, antispam
software reduces amount of phishing emails, SPF, DKIM and DMARC protocols help to verify whether
email senders are legitimate.

Some solutions for mitigation of internal threats can also help to deal with the task. For instance, some

in various situation, including potentially dangerous ones.

email compromise.
