Never heard of EDR or ...
"EDR" is/was the next evolution of "antivirus". EDR = Endpoint Detection and Response. It works quite differently than traditional antivirus as we know it. You can actually pair it with traditional (legacy) antivirus software...although most don't.
Where traditional antivirus engines work via definitions, and scanning files, and they can do a bit of heuristic and behavior blocking,
EDRs work differently, EDRs monitor the behavior of all applications, to detect suspicious or anomalous activity, and they automate containment, remediation, investigation, and rollback. They are meant to create full reports of the incident, and tie into SIEM solutions.
EDRs do require more configuration and setup, and more ongoing maintenance and tuning.
One of the early bigger names of EDRs is Sentinal One. We provide that for our clients that have cyberinsurance that dictates EDRs.
While we do Bitdefender with our RMM for most clients, we don't use their EDR....and I'm shifting away from Bitdefender...moving towards Microsofts "Defender for Endpoint" managed by 365BizPrem. Which is substantially more powerful than the plain stand alone Defender AV built into Windows...the 365 tenant unlocks many features. The regular Defender P1 in Biz Prem doesn't unlock all the features to make it a full EDR, however Defender P2 does....for clients that need it.
There are dozens of EDRs out there, many of the traditional "big brands" of AV make them, such as BD, Eset, Symantec, TrendMicro, and others. Some big EDR brands I see in various tech forums...Huntress is big, Cylance, Crowdstrike also...and the SentinalOne I mentioned above.
The Malwarebytes that the OP mentions here is not the vanilla MWB most here think of...MalwareBytes makes a full EDR product that is totally different that the "cleaner".
But wait....didn't know what EDR is? We've already evolved beyond that too!
XDR and MDR!
Well, MDR Isn't too different from EDR..it's just Managed Detection and Response. Meaning, a service that more automates and takes care of things going on. You purchase this as a service, offload the work from your.
However, XDR is an evolution of EDR..."Extended Detection and Response"...on the large scale. It ties together endpoints, as well as other avenues into systems....firewalls, email, web filtering, network analyses, even identity and access. It really looks at "the whole picture"...ties it all together, and makes its moves globally on the entire infrastructure from top to bottom. Microsofts Defender plans are evolving into this...as it manages more than just endpoints, it also ties in url filtering, email attachments, cloud file storage, endpoints,
