Importance of Impersonation Protect in Mimecast
by Rick Pabst – Senior Support Engineer
Email, and the internet in general, were developed by a group of very smart, competent people. They assumed that everyone using these technologies would be doing so in good faith, as most people do. There is, however, a growingly large percentage of bad actors pretending to be someone they’re not when sending email. This is often in attempt to get you to do something you don’t want to do.
That’s where tools like Impersonation Protect in Mimecast come in to play. This is their effort in stopping the pretenders, letting only the legitimate senders through.
If Impersonation Protect is triggered, Mimecast will send you a message letting you know this has happened, along with sender and recipient information. In most cases it will be obvious that the email is a not from who it says it’s from. In those cases, you can just ignore the email and go on about your day. But... It’s important to note that the system is not flawless. There will be times when Impersonation Protect will hold a legitimate email that you’re expecting. If the email does look safe, or like one that you are expecting, please reach out to us! We will gladly verify that the email is safe and release it to your inbox.
