What is Extended Detection and Response (XDR)

With changing technologies, cyber threats are evolving and defenders must keep up. How can XDR empower companies to protect themselves?

The cybersecurity threat landscape is continually changing and expanding. As a result, many businesses are attempting to develop their security capabilities, to quickly and effectively identify and stop unusual, sophisticated, and fast-moving threats.

The most common strategy for a security platform is a “layered” strategy, in which a company uses several solutions, such as endpoint detection and response (EDR), network traffic analytics (NTA), and security information and event management (SIEM), to implement defense in depth across various platforms. 

The approach used by Extended Detection and Response (XDR) is different. By providing unified awareness across multiple attack vectors, XDR enables an organization to proactively protect itself against cyber threats as opposed to taking a reactive approach to cybersecurity.

This blog walks you through what XDR is and how it works. Read on!

What Is Extended Detection and Response (XDR)?

Extended detection and response (XDR) is a security tool that protects IT infrastructure by enhancing visibility, analyzing threats quickly, and responding rapidly. It serves as a security solution that unifies many security products into a single security platform, enhancing the capacity to recognize and handle security issues. It gives enterprises a complete view of the threat landscape across the technological ecosystem and unifies visibility into various attack vectors.

Endpoint detection and response (EDR) tools logically evolved into XDR, a key incident response tool. By offering a better idea of threats across the technology landscape, XDR lets a company go beyond conventional investigative controls.

XDR provides security operations with real-time actionable threat intelligence resulting in quicker outcomes.

How does XDR work?

Data analysis

Endpoints, networks, servers, and the cloud are just a few security locations where XDR gathers information. Data analysis is done after data aggregation to correlate context from multiple alerts that are generated. Security teams can now focus on high-priority signals or alerts instead of dealing with a large volume of security notifications.

Threat detection

XDR provides excellent insight into an organization’s IT infrastructure. As a result, the system can investigate any threats it detects and notify any critical ones that need to be addressed. The visibility factor also helps businesses thoroughly examine threats’ aberrant behavior and look into their sources before they impact other system components.

Attack response

In the final phase, XDR contains and eliminates any dangers found. It then makes security policy adjustments to prevent a recurrence of the incident in the future. 

Summing Up

XDR systems are adaptable and efficient security enforcement and remediation solutions in a threat environment that is becoming more sophisticated. XDR technologies increase effectiveness and reduce the amount of time a malicious user might spend on an enterprise network for firms looking to optimize security analyst time and burden. XDR seamlessly integrates into an enterprise’s current ecosystem, reducing onboarding time and increasing productivity.
