What Are Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR)? How Do They Differ?

What Are Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR)? What Sets Them Apart?

Endpoint Detection and Response (EDR):

EDR is a cyber security solution developed to secure endpoint devices (computers, servers, mobile devices and so on). By monitoring the activity taking place on endpoint devices, EDR makes it possible to detect threats and respond to them quickly. EDR systems analyse the source of attacks and their potential to spread, so that security teams can take countermeasures quickly and effectively.

The core functions of EDR are:

Threat monitoring and detection: monitoring abnormal behaviour and threats on endpoint devices.

Threat analysis: analysing the source and impact of threats.

Response: automatic or manual response to detected threats.

Threat hunting: allowing security teams to search proactively for potential threats.

Extended Detection and Response (XDR):

XDR is an advanced cyber security solution that delivers the endpoint security EDR provides, but on a much broader scale. Alongside endpoints, XDR also integrates data from the network, email, cloud and other security layers. Data coming from different security points is brought together to form a unified threat management platform. By offering a more comprehensive detection and response process, XDR increases security teams' overall visibility and identifies complex attacks more effectively. The core functions of XDR are:

Unified threat monitoring and detection: detects threats by combining data from different security layers.

Advanced analytics: uses advanced analytics and artificial intelligence to detect threats more accurately.

Central visibility: makes it possible to view every security event on a single dashboard.

Automated response: can respond to threats automatically and prevent attacks from spreading.

The differences between EDR and XDR

EDR focuses solely on the security of endpoint devices. XDR covers endpoint security along with other security layers such as network, email and cloud.

EDR uses only data coming from endpoint devices. XDR integrates data from other security layers in addition to endpoint data.

EDR focuses on threats detected on endpoint devices. XDR detects threats across every security layer, endpoints included, and offers an integrated response process.

EDR systems are narrower in scope and generally simpler in structure. XDR is broader and more integrated, so its structure is more complex — but it also provides more advanced threat detection.

In short, while EDR secures endpoints, XDR offers a wider security perspective, bringing different security layers together and providing more comprehensive threat management. For more information about the solutions that suit your security needs and your infrastructure, please get in touch with us.
