The cyber-insurance form asks whether every computer has EDR. Here is what those three letters mean, in plain English.
Antivirus keeps a list of known bad files and blocks anything that matches, so it only recognizes what is already on the list. EDR, short for endpoint detection and response, watches how each computer behaves and flags anything out of the ordinary, even when nothing on the list matches. It also lets a person isolate one computer while everyone else keeps working.
The useful question is not whether you have it. It is who watches it for your office.
