## What do the three acronyms actually mean?

EDR stands for endpoint detection and response, sometimes called endpoint threat detection and response. It is a cybersecurity technology that continually monitors an endpoint, meaning a client device such as a mobile phone, laptop or Internet of Things device, to mitigate malicious cyber threats. The term was coined in 2013 by Anton Chuvakin of Gartner to describe tools primarily focused on detecting and investigating suspicious activities and other problems on hosts and endpoints. Today the concept is usually called EDR and is often managed through endpoint protection platforms.

XDR stands for extended detection and response. It is a cybersecurity technology that monitors and mitigates cyber security threats. The term was coined by Nir Zuk of Palo Alto Networks in 2018. According to Chapple, Stewart and Gibson, XDR is not so much another tool as the collection and integration of several concepts into a single solution, with components varying from vendor to vendor and often including network traffic analysis, network intrusion detection systems and network intrusion prevention systems.

Gartner's definition, quoted in the sources, says XDR delivers security incident detection and automated response capabilities for security infrastructure. XDR integrates threat intelligence and telemetry data from multiple sources with security analytics to provide contextualisation and correlation of security alerts. Gartner adds that XDR must include native sensors, can be delivered on-premises or as a SaaS offering, and is typically deployed by organisations with smaller security teams.

MDR stands for managed detection and response. CrowdStrike describes it as endpoint security as a service: a service that manages endpoint security technologies for organisations, which includes EDR. SentinelOne describes MDR as integrating advanced technology with skilled professionals to deliver real-time monitoring, threat detection, analysis and rapid response to cyber threats. SentinelOne frames MDR as addressing two pain points: the increasing complexity of cyber threats and the lack of in-house expertise. It says this matters especially for understaffed teams, teams already experiencing alert fatigue, or teams with limited resources to establish a comprehensive security operations centre.

## How does EDR work in practice?

EDR gathers and analyses security threat-related information from computer workstations and other endpoints. The goal is to find security breaches as they happen and support a quick response.

An EDR system collects and aggregates data from endpoints and other sources. That data may or may not be enriched by additional cloud analysis. The data may be stored in a centralised database or forwarded to a SIEM tool for cyber monitoring. EDR solutions are primarily an alerting tool rather than a protection layer, though functions may be combined depending on the vendor.

A dedicated agent installed on the endpoint collects data, or the system might use built-in capabilities. The data sources include logs, performance monitoring information, file details, running processes and configuration data. EDR often collects and analyses telemetry, network connection and endpoint activity log data.

When EDR detects a threat, it initiates automated or manual responses, such as isolating affected endpoints or alerting security teams. EDR systems protect most operating systems, including Windows, macOS, Linux and Berkeley Software Distribution, but they do not include network monitoring.

EDR is not antivirus software, although it may have antivirus capabilities or use data from another antivirus product. Antivirus software is primarily responsible for protecting against known malicious software. A well-executed EDR programme finds new exploits as they are running and detects malicious activity during an active incident. EDR can detect fileless malware attacks and attackers using stolen credentials, which traditional antivirus software cannot stop.

## How does XDR work in practice?

XDR collects and correlates data across network points such as servers, email, cloud workloads and endpoints. The data is analysed and correlated, which lends it visibility and context and reveals advanced threats. Threats are then prioritised, analysed and sorted to prevent security collapses and data loss.

Microsoft describes data ingestion from endpoints such as laptops and servers, cloud workloads and applications, email traffic and messages, user identities and authentication events, app usage and activity, and network traffic and connections. Analytics, AI and machine learning analyse that data in real time, looking for anomalies, suspicious patterns and attack techniques that traditional security tools often miss.

Incident correlation then connects related alerts to show the bigger picture. Microsoft's example: a phishing email, a compromised account and unusual endpoint activity might be linked as part of the same coordinated attack. This reduces noise and highlights incidents that need urgent attention. Once a threat is confirmed, automated workflows can isolate an affected device, disable a compromised account, or block malicious processes or traffic.

The XDR solution monitors the malware detection and antivirus capabilities of the EDR system and many extra cyber log sources to create greater context for security operations centre teams, so they can perform faster threat detection, investigation and response. It is described as an alternative to reactive endpoint protection solutions such as EDR and network traffic analysis.

## Why do organisations end up with too many tools?

CrowdStrike sets out the problem plainly. Previous incarnations of threat detection solutions focused on one layer of the security architecture at a time: EDR solutions monitor endpoints, while network traffic analysis solutions are dedicated solely to network traffic. Data from these tools is rarely integrated or unified, which prevents the organisation from having complete and accurate visibility across the enterprise.

Buying several individual security products to build a multilayered architecture can create a complex security stack that delivers many alerts without proper context. As more tools become involved, investigations become more difficult, which CrowdStrike says is one reason the length of time required to identify a breach has increased in step with the adoption of the multilayered security model. Relying on individual tools also creates silos and gaps, and the more complicated the silos, the greater the likelihood a security gap goes unnoticed until there is a breach.

One 2021 study cited in the sources found that 32% of organisations used between 21 and 30 separate security tools in response to each threat, and 13% used more than 31 tools.

## Do small and mid-sized businesses need MDR, EDR or XDR?

The sources give several signals rather than a single rule.

Gartner's definition notes that XDR is typically deployed by organisations with smaller security teams. Microsoft says XDR helps simplify operations, reduce alert fatigue and strengthen overall security posture for both large enterprises and growing small and medium-sized businesses, and lists growing adoption by small and medium-sized businesses among emerging trends in XDR.

CrowdStrike describes EDR as the baseline monitoring and threat detection tool for endpoints and says it is central to every security strategy, and says organisations should select a tool providing the right level of coverage based on the risk profile of the business. It also notes that the main benefit of MDR is rapidly identifying and limiting the impact of threats without the need for additional staffing, which it links to the global shortage of highly skilled cybersecurity professionals and the related skills gap, particularly for protection of cloud-based systems and assets.

SentinelOne describes EDR as suited to security engineers who want granular control of the environment but do not have 24/7 resources. It describes XDR as helpful for teams with a complex setup that must respond swiftly to threats, because it gives a complete view of all systems at once instead of leaving security solutions in isolated silos.
