The Differences Between EDR and MDR


By Matt Blackmore, on 27 Apr 2021

With so many acronyms in cyber security, it isn’t always easy to distinguish between the many product and service offerings available.

This can create significant confusion for IT and security personnel that need to make quick purchase decisions to address holes in their security coverage.

Two of the more common acronyms that are likely be encountered by organisations looking to improve threat detection and quickly shut down threats are EDR (Endpoint Detection and Response) and MDR (Managed Detection and Response). This blog seeks to clarify the differences between the two and help buyers make the right security investments.

What is EDR?

Endpoint Detection and Response (EDR) is a term used to describe cyber security technologies that help organisations detect threats that target host devices such as laptops, servers and desktops. EDR combines elements of next-gen antivirus with additional functionality to deliver real-time anomaly detection, support threat hunting and help automate incident response processes.

EDR solutions work by collecting endpoint data and using behavioural analytics to examine it for evidence of suspicious activity. When an anomaly is detected, an alert is generated for human investigation. Endpoint telemetry can be used to perform kill chain analysis, contain and quarantine infected devices, create custom threat watchlists and block malicious IPs. This provides security teams with a crucial layer of visibility to identify and respond to intrusions.

What is MDR?

Managed Detection and Response (MDR) is a term used to describe a service that combines human expertise, threat intelligence and a range of network and endpoint detection technologies to help organisations detect and respond to threats.

Managed Detection and Response services, delivered by specialist MDR providers, are designed to help organisations that lack extensive internal expertise and resources to achieve an enterprise-grade cyber security capability at a fraction of the cost of building the same capabilities in-house.

MDR acts as a virtual extension of an organisation’s in-house team to hunt for and respond to cyber threats around-the-clock. Going well beyond the scope of a traditional managed security service, MDR providers proactively hunt for, investigate and provide the support needed to swiftly remediate threats 24/7.

The challenges of in-house endpoint monitoring

As the number of sophisticated cyber threats continues to grow, the perimeter security controls that have traditionally been relied upon are now insufficient. This has made it vital to swiftly detect and respond to threats that are able to bypass the security perimeter.

With an increasing number of cyber threats now specifically targeting endpoints, EDR technologies have become essential in helping organisations to identify and disrupt threats at the earliest stages of attack. The problem for many organisations, however, is that they lack the skills and resources needed to get the most out of them.

The cost of buying and integrating the necessary technology is already extensive, but organisations also need to hire and train dedicated staff to manage them.

Many organisations rush into expensive technology investments without considering the resource burden. The potential that solutions like EDR offer is significant, but no organisation can expect to unlock this potential without a dedicated team to proactively configure, manage and monitor them around-the-clock.

Overstretched IT teams without specialist security training often struggle to implement technologies effectively to maximise their value, and can quickly find themselves suffering from alert fatigue, leading to important information being ignored and rendering the technology redundant.

These challenges have led many organisations to seek out managed security services to help bridge the resource gap.
