The Seven Categories of MDR - #5 – ED-Big-R (Single Telemetry)

4 min read

Emerging from the traditional managed security service provider (MSSP) model, Managed Detection and Response (MDR) is an answer to the fact that threat actors have increased their ability to circumvent traditional detection measures. As early as 2011, MDR emerged (uncategorized at the time) with a single guiding principal: Acknowledge that a breach will happen. When it does, minimize threat actor dwell time to reduce risk.

However, as the MDR market has evolved, four criteria remain constant as key to minimizing threat actor dwell time in the event of a breach: visibility, fidelity, detection capabilities and response. When these criteria are measured against in-house resources, risk tolerance and available budget, they can be used to choose the appropriate MDR vendor based on your organizational requirements.

To help organizations make an informed cybersecurity solutions choice, eSentire has authored, The Definitive Guide to Managed Detection and Response (MDR) (and this blog series) which examines seven categories of MDR providers, measured across four criteria, which include:

MDR Category #5 – ED-Big-R (Single Telemetry)
EDR vendors are a viable option for organizations that lack the resources specifically to monitor, investigate and respond to endpoint threats, but have in-house resources to correlate endpoint data from the MDR vendor with network, log, cloud and vulnerability telemetry to detect and respond to threats out of provider scope.

Profile
Similar to EDr, outlined previously, ED-big-R (EDR) is an evolution of a subset of the MDR vendor landscape. Virtually all EDR vendors own, manage, monitor and respond to their own proprietary end- point software. Deep machine learning and behavioral processes are highly integrated, thereby facilitating threat hunting and rapid response to elusive endpoint threats.

Management, monitoring, hunting and containment capabilities were developed secondary as value-adds for clients who lack adequate in-house resources.

Many EDR vendors provide an EPP in addition to EDR, alleviating the need for multiple agents. Additionally, next-generation antivirus data empowers threat hunters with data that can expedite investigation and response by providing important additional context.
