What Is the Extended Detection and Response (XDR) Methodology?

XDR is just good security. 

It is a strategic approach that breaks down data silos, improves visibility and reporting, and leverages automated threat remediation to make security teams more effective and efficient.

Taking action, rather than just sending alerts, has become critical for organizations to not only reduce risk but to optimize operational efficiencies by responding to threats faster than the industry standard, significantly reducing MTTR (Mean Time To Remediate).

By leveraging automation, SOCs can aggregate reporting from multiple point tools and orchestrate response and protection across an organization’s existing toolsets.

At the core, SIEM and SOAR platforms are used to synthesize multi-domain telemetry to provide one unified, threat-centric command console.

  • XDR is a methodology, not just a technology
  • XDR gives you better data using native tasks
  • XDR breaks down data silos
  • XDR reduces MTTR (Mean Time To Remediate)


What Is XDR?

Extended Detection & Response is a holistic security methodology that will typically leverage a SaaS-based security tool to extend past where traditional endpoint detection and response (EDR) leaves off.

XDR strengthens the security posture of an organization by improving visibility across the tech stack, reducing mean time to detection (MTTD), and improving accuracy. A well-built XDR strategy will protect the organization from potential business impacts and uncover efficiencies for SecOps teams.

An effective XDR strategy will typically include the following three components:

  1. Visibility: You need to be able to see what is happening on your systems in order to protect them. This means having visibility into devices, applications, users, and data.
  2. Threat Detection: You need to have the ability to detect malicious or unauthorized activity on your systems. This includes using the right tools and techniques to detect threats, as well as having a good understanding of your environment and what is normal activity.
  3. Response: You need to be able to quickly respond to threats when they are detected. This includes having the right processes and tools in place to respond to threats, as well as having the right people on your team who are able to take action.

If there is a security incident, XDR’s real-time information can help deliver better and faster outcomes. This improves the protection of business operations and the productivity of operational security personnel.

XDR provides enterprises with a comprehensive view of all their security-related data in one place. This makes it easier for security teams to quickly detect and respond to threats. XDR also includes forensics and case management features that are essential for investigating and resolving security incidents.

In short, XDR is a powerful security solution that can help enterprises improve their overall security posture.


How Does XDR Work?

XDR consolidates data from multiple sources, including endpoints, networks, and cloud services. This data is then analyzed to detect and respond to threats quickly and efficiently.

Once a threat is detected, XDR’s response capabilities provide security teams with the visibility to quickly respond and mitigate the threat. This includes remediation actions such as shutting down systems, quarantining files, or removing users from the network.

XDR also includes threat intelligence capabilities to help security teams stay informed of potential threats. By consolidating all of this information into one platform, XDR makes it easier for security teams to triage and respond to incidents quickly.

Additionally, XDR offers comprehensive analytics that provides detailed information on threats. The additional analytics visibility allows for better or more comprehensive root cause analysis to help make better decisions around how to protect your environment.

Last but not least, the XDR analytics system provides in-depth information on how to address specific threats, giving security teams the information they need to keep their networks and systems safe.


Why is XDR Important?

When defending their digital assets, enterprises need every tool at their disposal. Unfortunately, many traditional security tools and data sets are siloed. Due to this, the security staff is stretched thin and it struggles to keep up with the latest threats. This is where an XDR solution comes in.

An XDR solution brings together all relevant security data into a single platform, making it easier for security teams to identify and respond to threats. Additionally, the XDR methodology integrates security tools and systems, providing a more comprehensive view of the enterprise’s security posture. This is crucial in today’s landscape, where adversaries use more sophisticated tactics to bypass traditional security controls.

XDR solutions provide enterprises with the visibility and agility they need to stay one step ahead of the latest threats. By consolidating all relevant security data into a single platform, XDR solutions help enterprises reduce the risk of data breaches and other security incidents. In addition, they can help improve operational efficiencies by reducing the number of false positives and alert overload.

XDR is just good security.
