What is Endpoint Detection and Response (EDR)?

Endpoint Detection and Response captures all endpoint activities and uses advanced analytics to pinpoint anomalous behaviors across them. Security teams learn about the visibility of their endpoints and receive alerts regarding malicious events through EDR tools.

Key Features of EDR

EDR offers the following key features to enterprises:

• Traiages alerts and validates suspicious endpoint activities.
• Analyzes large data stores.
• Detects security events.
• Generates actionable threat intelligence.
• Generates appropriate and context-based threat mitigation responses.
• Gives deep visibility into multiple endpoints, including IoT devices, laptops, desktops, and others.

What is Managed Detection and Response (MDR)?

Managed Detection and Response (MDR) is a special type of Security-as-a-Service (SaaS) offering where you employ dedicated security professionals to monitor and mitigate threats. Unlike other security automation tools in your arsenal, MDR adds a human element.

These experts review and take instant action on security events that are normally not caught by your existing stack. For threats that are evolving or if your tools are not accustomed or aware of the latest development, MDR can identify and eliminate them. MDR is a great way to boost your overall security maturity levels across the enterprise.

Key Features of MDR

MDR brings security teams the following key features:

• MDR detects false positives and investigates alerts after it detects an incident. It provides proactive threat-hunting capabilities.
• It organizes security events, categorizes and prioritizes them, and lists them according to their risk levels. This helps security teams take action on the most critical ones first.
• MDR provides instant remediation and response to security events within a customer’s network.

What is Extended Detection and Response (XDR)?

XDR provides threat detection and response for cloud security tools, services, endpoints, and networks. It is an extension of traditional EDR solutions. XDR works best in complex and hybrid cloud environments and many companies request it as a software-as-a-service (SasS) offering.

Key Features of XDR

Modern XDR solutions should offer security teams the following features:

• XDR solutions combine endpoint telemetry with data from logs and information security platforms. It detects a large number of threats, including evasive maneuvers which are normally invisible to other investigation methods.
• XDR applies context-based machine-driven analytics, reduces noise, and identifies the root causes of threats.
• XDR solutions also make smart recommendations and provide guidelines for queries and other response actions.
• XDR should be able to prioritize risks, guide responses, and generate multiple alerts.

Critical Differences Between EDR, MDR, and XDR

The following are the critical differences between EDR vs MDR vs XDR solutions:

1. In-house Expertise vs. Security Automation

There is no need to hire security experts from outside your organization when you use MDR. It consolidates the use of both XDR and EDR tools, plus adds human expertise on top. MDR accelerates multi-domain threat analysis and can help secure firewalls, cloud security posture, sensors, networks, and any other elements of the company’s IT Infrastructure.

2. Data Ingestion and Threat Visibility

XDR generates multi-domain security telemetry and streamlines security data ingestion, analysis, and workflows. It provides unified response capabilities and enables access to top-tier threat intelligence. XDR can enhance visibility across entire enterprises and provide detailed network traffic security analysis. Another key benefit of XDR over MDR and EDR is that it accelerates security operations and unifies organizations’ cyber security strategies.

3. EDR vs MDR vs XDR: Integrations
