When it comes to managed detection and response (MDR) services, I'm starting to hear the same pressing question over and over again: Who actually owns the R? In other words, who exactly is responsible for each component of a response?Over the past few weeks, the chatter surfaced in separate emails and individual MSSP Alert conversations with:Still, the "Who owns response?" conversation stretches back further than that. At the Right of Boom conference in February 2022, JupiterOne CISO and head of research Sounil Yu described a world where people remain heavily involved in response and recovery services. The obvious question that MSSPs and end-customers need to address: Whose people?Still, actual MDR services -- particularly the response stage of the services -- vary widely from one company to the next.Similarly, Rapid7 is banging the drum for digital forensics and incident response capabilities as differentiators in the MSSP, MSP and MDR markets.

MDR Security Services: Widespread Adoption
The question -- "Who owns response?" -- is particularly important amid the spread of MDR services. Indeed:- MDR now ranks among the core eight managed security services typically offered by MSSPs, according to Gartner.
- Hundreds -- perhaps thousands -- of companies now claim to offer MDR services. The MDR proponents include cybersecurity software companies, pure-play MDR businesses, MSSPs, and MSPs that are white labeling third-party services.
- Fully 91% of MSSP 250 survey participants for 2021 indicated that their companies offer MDR capabilities.
MDR Security: What Are 'Response' Services?
Amid that backdrop, eSentire divides the MDR discussion into this spectrum:- Detection: Actually spotting a threat to a business;
- Response: Containing that threat;
- Remediation: Making sure the adversary is removed from the system for good; and
- Digital forensics with incident response: Performing digital forensics, analysis, crime scene reconstruction, eDiscovery and more.
