What Is MXDR and Why Do You Need It?

MXDR Benefits

Leveraged effectively, Managed Extended Detection and Response has the potential to advance organizational security in several ways.

• Enhanced Threat Detection

  By harnessing advanced analytics, artificial intelligence-led algorithms, and the expertise of security specialists, MXDR enables organizations to dramatically enhance their ability to detect threats before they cause disruption. Because MXDR allows data monitoring across many different sources, it delivers greater visibility and more nuanced and complete threat detection, supporting long-term cyber resilience. 

• Accelerated Incident Response

  Managed XDR speeds up incident response because it streamlines organizations’ security operations. While fragmented approaches mean that organizations’ systems often work in silos, MXDR consolidates all security data. This provides a clearer and more immediate overview of a company’s security status, enabling in-house teams to respond to and resolve issues more quickly and effectively.
  MXDR harnesses SOAR to speed up the process of triage and remediation, standardizing and accelerating the whole mitigation process. By reducing the mean time to detect and respond to threats, MXDR enables businesses to minimize the potential disruption caused by cyberattacks.

• Increased Visibility

  MXDR allows organizations to achieve a more comprehensive overview of their security posture. By combining machine and human learning and combining many different data sources into one “pane of glass”, it provides real-time visibility into an organization’s security status. MXDR also highlights how specific alerts and incidents are interconnected, providing actionable insights and reducing the burden on already pressured security teams. This then enhances response to incidents and increases visibility, helping organizations to identify key threat patterns and mitigate potential security issues.

• Improved Threat Analysis

  Managed XDR enables organizations to build their knowledge of specific threats to help support a proactive approach to addressing them. This is because it collects and analyzes very large quantities of data about the unique threats that can impact an organization, contextualizing it between data sources to significantly enrich alerting.
  
  As well as known threats, MXDR supports the detection of emerging threats that other security approaches may not have identified. In this way, MXDR allows companies to better understand their particular threat landscape and empowers them to resolve potential vulnerabilities before they are exploited by threat actors.Real - Time Monitoring
  
  Because MXDR solutions automatically monitor endpoints and networks, they enable 24/7 threat monitoring. When MXDR identifies a genuine security incident, real-time analysis and automated response actions accelerate the speed at which risks are mitigated. Through MXDR’s artificial intelligence and automation processes, organizations can more quickly detect threats, reducing the time internal security teams spend manually investigating them.

MXDR vs MDR vs EDR

• MDR vs MXDR

  MDR and MXDR are closely related because MXDR draws on the best of MDR to function. They are both outsourced security services that pass over responsibility for network security to a team of experts specializing in threat detection and response. Both MDR and MXDR provide endpoint security to continuously monitor endpoints for indicators of compromise. Both also proactively help neutralize identified threats and send alerts to security operations center (SOC) teams.
  
  Through XDR integration, MXDR provides a cross-platform approach to endpoint detection and response that streamlines security data ingestion, analysis, and workflows across an organization’s entire security stack.

• EDR vs XDR

  XDR is sometimes referred to as the next step from EDR (Endpoint Detection and Response). Both technologies aim to take a proactive approach to security, and provide rapid threat response and threat-hunting support. However, a key difference is that while EDR focuses on endpoint protection to provide visibility and threat protection for specific devices, XDR unifies security across all endpoints, networks, cloud, email, and other event sources. XDR platforms work more broadly, ingesting the same type of telemetry used by EDR tools but also integrating and analyzing data from other areas of an organization’s environment.
  
  Integration is another key difference: EDR solutions are manually integrated with a set of point solutions, while XDR provides visibility and threat management within a single solution. XDR makes EDR’s whole approach more sophisticated, enabling security teams to go beyond logging and reporting on security incidents on an endpoint to do so across the whole attack kill chain. This means that XDR delivers broader visibility at every stage of the kill chain.

MXDR Features

While the provider will define the specific capabilities of Managed XDR, it usually includes certain aspects.

• Threat Hunting

  MXDR is fueled by threat hunting, a proactive approach to cyber defense in which security analysts search through network, cloud, and endpoint system logs to find undetected threats. Through Managed XDR, organizations benefit from continuous threat detection using threat intelligence and an approach that combines the best human expertise with data-driven insights.

• Response Automation

  Managed XDR incorporates SOAR. Through response automation, custom playbooks are developed to automate actions about specific threat scenarios, like endpoint isolation and threat containment. XDR experts can guide customers through more complex remediation and recovery requirements or manually intervene in high-severity incidents.

• Threat Intelligence

  Threat intelligence is a key feature of Managed XDR because the information drawn from cyberattacks delivers valuable insights into specific threats. Security experts analyze these insights to better understand the nature and behavior of threat actors to reduce the risk of attacks. Threat intelligence informs the strategy and performance of MXDR, ensuring that the steps taken are precisely targeted to the specific threats affecting an organization.

• Vulnerability Management

  Vulnerability management is an ongoing approach that involves identifying, assessing, managing, and addressing vulnerabilities in endpoints, workloads, and systems. MXDR usually includes a vulnerability management program that enables risks to be prioritized and vulnerabilities to be addressed as quickly as possible.

• Remediation

  Managed remediation is critical to MXDR because it enables the restoration of systems to the state they were in before an attack. Remediation actions may include removing malware, cleaning the registry, ejecting intruders, and removing persistence mechanisms.

What to Look for in an MXDR Vendor

With Managed XDR vendors varying widely in terms of capacity and approach, it is essential to assess potential providers based on a range of criteria.

• Deployment

  Without the right expertise, deploying MXDR solutions can be a lengthy and complex process. Organizations can also find it challenging to collect and correlate detections and other activity across many different security layers. Ensure that your chosen MXDR vendor can demonstrate an effective deployment process and provide consistent transparency and an appropriate level of support at every stage of the process.

• Advanced Telemetry

  To be truly effective, XDR solutions must be “fed” the right telemetry and intelligence to be capable of continually detecting the latest threats. Check that your chosen MXDR vendor constantly reviews and updates detection policies and processes.

• 24/7/365 Monitoring

  Look carefully at the level of support your prospective vendor can deliver. Ask them about the breadth of specialist resources and support they have in place to ensure that the solution is supported 24/7/365 at a level that will maximize its performance.

• Incident Response

  An effective MXDR provider will be able to demonstrate their experience and knowledge of incident response to advise and support an effective incident response plan alongside experts on hand to analyze, isolate, and eliminate threats as quickly as possible.

• Threat Intelligence Integration

  Threat intelligence is a critical element of MXDR. Your Managed XDR provider should be capable of delivering ongoing insight into the latest threats that may impact your business while also turning this intelligence into active detection, hunting, and response efforts. Assess whether your chosen provider offers threat intelligence that includes a variety of organic, open-source, and proprietary sources and can identify known attacker indicators such as an IP address, internet domain, and file hash, as well as methods and behaviors used by attackers.
  
  A critical aspect of this is ensuring that your MXDR provider has an adversary-driven mindset or has teams beyond their core SOC that engage with live attacker campaigns and use this information to frequently update detections. This requires close integration between threat intelligence analysts, malware analysts, and detection engineers.

• Transparent Service Delivery and Processes

  Your MXDR partner should provide a nominated team to act as the point of contact for strategic security advice and service-related queries. This will help keep you informed about the overall service quality. Managed XDR providers should offer a service portal that provides a unified view of alerts and incident activity across your digital estate, along with self-service features for tracking service requests, KPI-driven reporting, and defined response playbooks.
