Hi, was pointed to this post. Pedro Bustamante here, head of research and innovation at malwarebytes... excuse the old Panda icon
I can confirm both the MB4core and corporate EP core detection is exactly the same. We do have a separate EDR business product that includes a few more cloud-based detection technologies, but that was not tested at MRG. The bad performance rating was a config error on our part as we provisioned EDR instead of EP (even though the EDR detections don't count for points in the MRG test). In the next test you'll see the real performance impact comparative.
In terms of participating and focusing on 3rd party tests, we made the decision about a year ago to focus on improving in these tests. The launch of Katana by incorporating a few more static (sig and heuristic) and dynamic (runtime sandbox) engine layers has helped bridge the historic gap. During the process we found and fixed bugs as well as created new protection and detection capabilities for existing engine layers, so the exercise to adapt to testing was valuable. We signed up for AV-Comparatives (for both MB4 and Malwarebytes EP) and also AV-Test business tests. You will start seeing Malwarebytes for the first time ever in these tests soon.
