MDR, or Managed Detection and Response, operates like an always awake security guard. It combines advanced technology, human expertise, and rapid incident response to detect, analyze, and remediate cyber threats. Unlike a traditional managed security services provider (MSSP), MDR focuses on proactive threat hunting and rapid response.
Imagine having a 24/7 personal bodyguard that not only protects you but also predicts and prevents potential threats. That’s what MDR is intended to be for your cybersecurity. Most MDR solutions should offer to:

  • Block threats
  • Closely investigate the forensics behind endpoint and network attacks
  • Provide a dedicated team of exceptional cybersecurity experts
  • Monitor alerts, analyze security events, decide on the right action, and search for threats in your network

Thus, MDR bridges the cybersecurity skills gap in your organization, providing the resources you need to achieve better security.

The Anatomy of MDR Services

MDR services function seamlessly, with each component playing a significant role in maintaining and enhancing your organization’s cybersecurity. These services typically include:

  • Continuous monitoring
  • Threat detection
  • Threat triage
  • Incident response

These features are supported by advanced analytics, threat intelligence, and security technologies, forming a robust security operations framework. It’s comparable to having dedicated security teams constantly patrolling your organization’s networks and systems, poised to act at the first hint of trouble.

Continuous monitoring is the heartbeat of MDR services. Without monitoring, there wouldn't be many alerts to investigate. Monitoring is like having a watchful eye constantly scanning your organization’s networks, devices, and data to spot and respond to security threats. While traditional MDR services focus on monitoring and reacting to threats as they appear, some may want to consider adding a proactive aspect to bolster their security posture. Proactive threat hunting can be like adding an active police patrol who actively seeks out and investigates potential threats before they can cause any harm. It goes beyond traditional security monitoring and incident response. In an attempt to stay a step ahead of threats.

Proactive Threat Hunting as a Compliment to MDR

Proactive threat hunting makes an excellent compliment to MDR, much like a detective is indispensable for solving a mystery but active police presence can help prevent crimes from happening. That said, much like having an area policed does not prevent all crimes from being committed, proactive threat hunting can’t prevent incidents from happening, but it may help identify and neutralize threats before they can cause significant damage to an organization’s infrastructure. 

Proactive threat hunting involves:

  • Leveraging tactical threat intelligence to identify known indicators of compromise (IOCs) and indicators of attack (IOAs) associated with new threats
  • 24/7 multi-signal correlation of potential threats through log analytics
  • Detecting potential security threats before they cause damage

Taking a proactive rather than reactive approach to finding potential threats before they find you can improve your overall security posture but should not be considered as a primary security strategy. Threat hunting can provide a false sense of confidence and while it helps organizations stay one step ahead of potential advanced threats and strengthens their overall security defenses in the evolving threat landscape, it shouldn’t be considered as an adequate replacement for detection and response. (I’ll cover more on Proactive Threat Hunting in a future series.)

MDR versus Traditional Security Solutions

MDR and traditional security solutions such as EDR, XDR, and MSSP are analogous to different superheroes, each with unique powers. While all are essential for cybersecurity, MDR stands out with its more focused, proactive, and human-led approach to threat detection and response. It’s like the difference between a superhero who waits for trouble to happen and one who actively seeks out potential threats and neutralizes them before they can cause harm.

Think of endpoint detection and response (EDR) as a part of the toolkit used by MDR providers. It stores activities and events which take place in endpoints of the network. This data is then sent to the system with automated rule-based analysis and responses. If an anomaly is detected, it’s sent to the security team for a closer look.

Extended detection and response (XDR) on the other hand, expands EDR capabilities beyond endpoints to safeguard varied attack vectors and gather data from diverse sources like endpoints, cloud, and more.

The Role of Human Expertise in MDR

If MDR is a superhero, then human expertise is its superpower. Skilled analysts and threat researchers work together to investigate, prioritize, and remediate threats in real-time. It’s like having a team of seasoned detectives working round the clock to ensure an organization’s cybersecurity.

The analysts and threat researchers staffing the MDR are highly skilled, possessing expertise in:

  • cybersecurity
  • threat intelligence analysis
  • threat hunting and research
  • detection engineering
  • incident response
  • machine learning and artificial intelligence (in some cases)
  • strong analytical and problem-solving skills

They are the Sherlock Holmes of the cybersecurity world, using their expertise and experience to analyze and interpret the data collected by MDR systems, give it context, and make decisions that reduce the effect of threats.

The Impact of MDR on Organizational Security Posture

Just as regular exercise and a healthy diet can enhance your physical posture, MDR can significantly improve your organization’s security posture. By lowering the risk of data breaches, boosting ROI, and ensuring compliance with industry regulations, MDR can significantly enhance your organization’s cybersecurity.

Think of MDR as a personal trainer for your organization’s cybersecurity. It helps manage resource limitations by quickly recognizing and minimizing the effects of threats without needing to hire more people. It provides:

  • Compliance assistance through log monitoring and storage
