Endpoint protection platform
Also known as EPP
The preventive layer on a device: antivirus, exploit mitigation, and policy enforcement that blocks threats before they run.
EPP is about prevention, EDR is about detection and investigation. Most modern products do both, but the distinction still matters when comparing quotes, because a cheap product may be prevention only with no ability to investigate afterwards.
Prevention will always miss some share of attacks. The question to ask a vendor is what happens on the day it does.
Where this comes up
Endpoint protection platform sits inside our cybersecurity and threats work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
