The Rising Threat of Cyber Attacks

Before diving into the details of EDR and MDR, it's important to understand why businesses need advanced cybersecurity solutions in the first place. Cyber attacks have been sharply rising over the past decade. One report found that the average organization faces over 30,000 malicious intrusion attempts per year. Breaches can lead to loss of sensitive data, financial theft, service disruptions, and damage to an organization's reputation.

Several trends are driving the proliferation of cyber attacks:

  • Workforce mobility - With remote work and bring your own device policies, securing every endpoint is challenging. Attackers exploit these vulnerable endpoints.
  • Increasingly sophisticated hacking tools - From malware to phishing scams, hackers use advanced techniques to infiltrate systems. No organization is immune.
  • High reward for cyber criminals - Data, credentials, and network access have significant value on dark web marketplaces. This motivates criminals to invest heavily in attacks.
  • More attack surfaces - Cloud, IoT, APIs, and more expand the potential attack surfaces. Each new surface provides new targets for hackers.

Facing this elevated threat landscape, organizations must deploy robust cybersecurity solutions. Both EDR and MDR strengthen defense, but in different ways.

What is Endpoint Detection and Response (EDR)?

Endpoint detection and response (EDR) focuses on boosting efficiency in threat detection and response from endpoints like laptops, servers, and mobile devices.

  • Key Capabilities of Endpoint Detection and Response:
    • Asset Inventory - EDR scans endpoints to develop a detailed inventory of assets and configurations. This provides visibility into potential weak points.
    • Behavior Monitoring - By analyzing patterns of activity on endpoints, EDR can build context to identify abnormal events that may signal threats.
    • Signature Detection - EDR tools contain libraries of threat signatures to recognize known malware and hacking tools.
    • Anomaly Detection - Going beyond signatures, EDR uses intelligent software to identify unusual activity or deviations from baseline that may indicate zero-day threats.
    • Alerts and Notifications - EDR software sends alerts when it detects potential security events for rapid response.
    • Log Aggregation and Analysis - EDR solutions store and analyze high volumes of data like system logs to understand endpoints' status and events.
    • Automated Responses - Many EDR platforms can take actions like isolating infected endpoints to promptly contain threats.
    • Forensics and Investigations - Detailed EDR logs support forensics investigations after incidents occur.

Overall, EDR consolidates prevention, detection, and response into one cohesive solution focused on securing endpoints. It brings advanced threat hunting to devices that often operate outside the corporate firewall.

What is Managed Detection and Response (MDR)?

Managed detection and response (MDR) involves partnering with a security service provider to manage your organization's entire security infrastructure. The MDR provider handles 24/7 monitoring, threat hunting, incident response, and more to provide enterprise-grade security services.

  • Why Organizations Adopt Managed Detection and Response:
    • Augments In-House Security - Most IT teams are stretched thin. MDR adds capacity for robust security.
    • Expertise - MDR providers have experienced security staff using the latest tools and threat intelligence. You benefit from their expertise.
    • Advanced Technology - MDR partners invest heavily in security capabilities. Clients gain access to superior technology.
    • 24/7 Threat Monitoring and Analysis - Continuous monitoring and analysis through MDR services allows the provider to detect threats in real-time.
    • Proactive Threat Hunting - MDR providers go beyond monitoring by proactively searching for indicators of potential intrusions across the infrastructure.
    • Incident Response - MDR partners have mature incident response plans to rapidly contain and remediate threats.
    • Compliance Support - MDR services like audits and reporting help demonstrate compliance with regulations like HIPAA.
    • Cost Savings - MDR can reduce expenses compared to building an in-house security team with advanced tools.

MDR offers comprehensive security management services tailored to your organization's needs. EDR tools are often included in MDR packages.

How MDR and EDR Work Together

While MDR and EDR are distinct solutions, they actually complement each other quite well. Here's how they work together:

  • EDR Deploys on Endpoints - The EDR software agent is installed on employee devices to monitor activity and detect endpoint threats.
  • EDR Feeds Data to MDR Platform - The MDR provider ingests and analyzes the rich EDR telemetry as part of comprehensive monitoring.
  • MDR Augments EDR - MDR experts and infrastructure provide broader correlation, threat intelligence, and response capabilities to enhance EDR.
  • Coordinated Incident Response - EDR and MDR coordinate to isolate, contain, and remediate threats across endpoints and the infrastructure.
  • Unified View of Security - MDR dashboards aggregate alerts and data from EDR and other sources for comprehensive visibility.
  • Continuous Feedback Loop - As the MDR provider responds to threats, new threat intelligence is fed back to the EDR software to strengthen prevention.

The integrated power of EDR and MDR provides end-to-end security with reduced complexity. EDR secures the endpoints while MDR connects it to the bigger picture.

Key Differences Between MDR and EDR

While both MDR vs EDR enhance an organization's security posture, they differ significantly:

Scope Protects full IT infrastructure Protects endpoints only
Management Fully managed security service Software you deploy and manage yourself
Protection Level Perimeter, network, endpoints, cloud, etc. Just endpoints
Approach Prevention, detection, response Detection and response focused
Capabilities Broad security services like threat hunting Provides a software toolset
Staffing Model Delivered by provider's security staff Your staff operates it

When to Choose Endpoint Detection and Response

EDR solutions are ideal for organizations that:

  • Have limited security staff and want to outsource endpoint monitoring and response
  • Need better visibility into endpoint activity to detect stealthy attacks
  • Require strong, real-time prevention and detection for endpoints outside the corporate network
  • Desire automated investigation and response capabilities at the endpoint level
  • Want to consolidate multiple endpoint security tools into a single solution

When to Choose Managed Detection and Response

MDR services offer the best value for organizations that:

  • Need comprehensive security but lack the in-house staff and expertise
  • Require 24/7 monitoring and response across infrastructure and cloud environments
  • Want access to advanced threat intelligence for proactive threat hunting
  • Seek to reduce complexity by partnering with an end-to-end security provider
  • Desire to shift security costs from capital expenses to flexible operating expenses
  • Are highly regulated and need to demonstrate rigorous security to auditors

EDR vs MDR Working Together

For advanced security, many organizations deploy EDR software for their endpoints, while leveraging MDR services for infrastructure-wide protection and response. This integrated approach provides comprehensive coverage across networks, cloud, identity, data, and devices.

With EDR providing localized detection and automated response at the endpoint level, and MDR centralizing monitoring, management, and expert threat hunting, organizations can stay steps ahead of attackers.

The right combination of EDR tools and MDR services can offer a highly effective security posture tailored to your organization's unique risks, resources and requirements.


As threats evolve, both EDR and MDR play pivotal roles in modern cyber defense. EDR secures and monitors endpoints, while MDR provides infrastructure-wide protection driven by a provider's threat experts.

Assess your organization's unique needs and environment to pick the right solution or combination. With robust EDR and MDR capabilities in place, you can focus on your business goals while strengthening your security.

The key is understanding the core differences between EDR vs MDR. EDR is software for endpoint security. MDR is a managed service spanning infrastructure. Use this guide to make the right choice for your organization's security strategy.

  • EDR software secures and monitors endpoints
  • MDR services provide infrastructure-wide security through a provider
  • EDR and MDR can work together for comprehensive coverage
