xdr

Extended Detection and Response (XDR) is a cybersecurity courses approach that identifies threats by unifying data from multiple security solutions, automating and speeding up detection, investigation, and response in ways that standalone solutions cannot. 

XDR can be provided as a tool or a suite of tools organizations deploy, manage, and operate.

Advantages of XDR

  • Identifies threats across various attack surfaces, including endpoints, services, networks, email, and cloud infrastructure.
  • Works across more layers and gathers more data than Endpoint Detection and Response (EDR) tools, allowing you to defend against multi-stage threats—attacks that end in a different place from where they started.
  • Unifies data from multiple security tools and technologies, including the XDR vendor’s products and third-party solutions, to offer visibility across key control points.
  • Provides optimized tools and workflows that enable you to investigate and hunt for threats across your environment using a single tool.
  • Rapidly contains threats with accelerated and automated response capabilities.
  • Enhances cyber insurance eligibility by lowering security risks.

How does XDR compare to other threat detection and response tools?

XDR vs. EDR

Endpoint Detection and Response (EDR) is a cybersecurity approach designed to monitor, detect, and respond to advanced threats and security incidents on endpoints, such as desktops, laptops, and servers. 

Endpoints are often the entry points for cyberattacks, making them a critical focus for security efforts.

XDR solutions analyze data across multiple attack surfaces, integrating data from endpoints, servers, cloud environments, networks, email, and other sources.

XDR vs. MDR

Managed Detection and Response (MDR) is a fully managed, 24/7 service delivered by experts specializing in detecting and responding to cyberattacks that technology solutions alone cannot prevent. 

By combining human expertise with protection technologies and advanced machine learning models, MDR analysts can detect, investigate, and neutralize advanced human-led attacks, preventing data breaches and ransomware.

With XDR, organizations leverage unified cybersecurity tools and workflows to manage detection and response activities.

XDR vs. SIEM

XDR shares functional similarities with SIEM (Security Information and Event Management) tools. Like XDR solutions, SIEM tools can collect and analyze enormous volumes of log events and other data across various sources. 

However, while SIEM is primarily a search tool—requiring users to ask multiple questions and then assemble the answers to conclude—XDR solutions can automatically respond to threats. 

In cases where automated response isn’t possible, XDR can speed up analyst-led threat hunts and investigations to improve response times.

XDR vs. SOAR

SOAR (Security Orchestration, Automation, and Response) platforms can add machine assistance to human security operators by creating playbooks (i.e., logic flows that can trigger scripted actions when certain conditions are met). However, SOAR will not create those processes or workflows for you. 

While SOAR can help with alert management, it requires a significant up-front investment in implementation and ongoing maintenance (tuning) by experienced security analysts to build effective case management and incident response playbooks.

How Does XDR Fit Into A Cybersecurity Strategy?

XDR brings a proactive approach to cybersecurity, allowing administrators to take quick action when faced with a threat. XDR operates at every stage of an attack, from infiltration to execution to recovery. 

Due to its broad capabilities, XDR is suitable for all types of IT infrastructure, whether in-house or in the cloud.

If your company is growing but your cybersecurity solutions haven’t been adjusted accordingly, it’s the perfect time to consider XDR. 

Additionally, XDR might be the solution you need if you have a well-staffed security team but are feeling overwhelmed managing multiple tools and services.

Many organizations are looking to consolidate security vendors and products to manage risk and improve the productivity of their security operations. 

XDR is an appealing approach that provides more accurate detection and prevention capabilities at a lower total cost of ownership. 

As a product or a managed service (MDR), XDR attracts security and IT leaders with limited resources who want to reduce their security program’s total cost and complexity.

When Should You Use An Xdr Solution?

XDR is the ideal solution for businesses with an established IT team but who feel overwhelmed by the many cybersecurity tools in place. An XDR solution consolidates those services and provides a unified approach.

XDR is crucial for organizations that manage multiple users and devices and those where some or all employees work remotely. 

There isn’t a specific list of sectors where XDR is most effective—it’s essential in any industry where sensitive information is stored or exchanged, from finance to healthcare. 

The right XDR solution can prevent hackers from stealing shopper information on an e-commerce site or stop criminals from encrypting files at a bank.

Business owners turn to extended detection and response solutions as cyber threats become more sophisticated.
