Endpoint Protection Platform

Cyberattacks have become more common, more advanced and more costly, which is driving the need for a comprehensive cybersecurity strategy. Central to every security strategy is a detection and response capability which catches threats that have circumvented traditional security measures. Here we explore three main detection and response tools:

Endpoint Detection and Response (EDR)
Managed Detection and Response (MDR)
Extended Detection and Response (XDR)

What is Endpoint Detection and Response (EDR)?

Endpoint Detection and Response (EDR) is an advanced cybersecurity solution designed to continuously monitor and record endpoint activities. It employs sophisticated analytics to deliver real-time visibility into the security posture of all endpoints, enabling the identification of anomalous behaviors, immediate alerting to the Information Security (InfoSec) team, and proactive recommendations for containment and remediation. This empowers organizations to swiftly neutralize active threats or mitigate their potential impact.

Key Capabilities of EDR Solutions Include:

Continuous endpoint monitoring and comprehensive event logging
Advanced data search, investigation, and threat hunting functionality
Triage and validation of security alerts related to suspicious activity
Detection and analysis of anomalous behaviors and threats
In-depth data analytics for enhanced situational awareness
Delivery of actionable threat intelligence to guide incident response
Tools and mechanisms for rapid containment and remediation actions

What is Managed Detection and Response (MDR)?

Managed Detection and Response (MDR) delivers endpoint security as a fully managed service. It encompasses the administration of advanced endpoint protection technologies—such as Endpoint Detection and Response (EDR)—on behalf of organizations. MDR providers offer a comprehensive suite of capabilities that typically include:

24/7 continuous monitoring of endpoint activity
Proactive threat hunting across the environment
Intelligent prioritization of threats and alerts
Expert-led investigation of suspicious events
Strategic guidance for incident response
Managed remediation to contain and resolve threats

The primary advantage of MDR lies in its ability to quickly detect, analyze, and mitigate cyber threats—without requiring in-house cybersecurity expertise. This is particularly critical in light of the global shortage of skilled security professionals and the widening skills gap, especially concerning the protection of cloud-native infrastructure and digital assets.

What is Extended Detection and Response (XDR)?

Extended Detection and Response (XDR) is a unified cybersecurity solution that consolidates security data ingestion, analysis, and operational workflows across an organization’s entire security ecosystem. By integrating telemetry from multiple domains, XDR enhances threat visibility—particularly for advanced and previously undetected attacks—and streamlines incident response.

An XDR platform aggregates and correlates data across the infrastructure to improve threat detection, reduce response time, and lower organizational risk. It normalizes, analyzes, and prioritizes threat data, delivering actionable insights to security teams via a single, centralized console.

Core Capabilities of XDR Platforms Include:

Integration of diverse, multi-domain security telemetry
Advanced threat-centric event correlation and analysis
High-fidelity detection with automated prioritization
Unified search, investigation, and threat hunting across multiple domains
Coordinated response and remediation to contain and neutralize threats

EDR vs MDR vs XDR

Endpoint Detection and Response (EDR) serves as the foundational layer of any cybersecurity strategy, providing baseline monitoring and threat detection specifically for endpoint devices. EDR solutions deploy software agents or sensors on endpoints to continuously capture activity data, which is transmitted to a centralized platform for analysis and threat identification.

Managed Detection and Response (MDR) builds upon EDR by offering it as a managed service. MDR provides outsourced endpoint security management with a focus on threat mitigation, elimination, and remediation—delivered by a dedicated team of experienced cybersecurity professionals.

Extended Detection and Response (XDR) advances the capabilities of EDR by expanding visibility and protection beyond endpoints to encompass the entire IT environment. XDR unifies data ingestion, threat analysis, and response workflows across the full security stack, enabling organizations to detect hidden, advanced threats and respond more effectively. When delivered as a managed service, XDR also includes access to expert threat hunters, intelligence analysts, and response specialists, further elevating the organization’s cyber defense posture.

Which Solution Is Ideal for My Organization?

Every organization's needs are different. While security is imperative, it is important to select a security tool that provides the right level of coverage based on the risk profile of the business.

Choose EDR if your organization:

Wants to improve its endpoint security posture and capabilities beyond NGAV
Has a Infosec team that can act on alerts and recommendations produced by the EDR solution
Is at the early stages of building a comprehensive cybersecurity strategy and wants to establish the foundation for a scalable security architecture

Choose MDR if your organization:

Does not have a mature detection and response program that can rapidly remediate advanced threats through existing tools or resources
Wants to introduce new skills and build maturity without hiring additional staff
Is struggling to fill skills gaps within the IT team or attract highly skilled, specialized talent
Wants protection to stay current on the latest threats targeting organizations

Choose XDR if your organization:

Wants to enhance advanced threat detection
Accelerate multi-domain threat analysis, investigation and hunting from a single console
Is suffering from alert fatigue across a disconnected or siloed security architecture
Wants to improve response time
Wants to improve ROI across all security tools
