Both EDR and XDR are valuable to every organization’s cyber security arsenal; but there are distinct differences between the two and some overlap. Endpoint Detection and Response (EDR) is an integrated security solution that facilitates real-time monitoring and data analysis for endpoint devices. EDR is based on the approach of “assume breach” mentality which means the tool uses high-end automation to rapidly identify and respond to threats.
On the other hand, an XDR solution collects and correlates data from several security layers. It involves threat analysis across emails, endpoints, servers, networks, apps, and clouds. XDR responds to threats just as quickly and effectively as EDR. However, it enhances visibility into the entire cloud estate. Its response scope is wider than an EDR tool and XDR provides centralized access to various security tools such as CASB, EDR, IAM, secure web gateways, network firewalls, and others.
In this guide, we will explore them both and explain how you can use them to prevent data breaches.
What is EDR (Endpoint Detection and Response)?
EDR collects in-depth data across endpoints and detects suspicious activities on hosts. It continuously enables rapid analysis of threats and implements rule-based automated responses. EDR solutions use a high level of automation to investigate endpoint security incidents and eradicate them before they escalate and transform into serious concerns.
Key Features of EDR
- EDR restricts endpoint device and network activity; it automatically detects and contains the threat. However, manual human review is needed before remedial action is taken.
- EDR platforms only fill the security gaps left by other security tools. EDR does not provide complete network security and has limited visibility.
What is XDR (Extended Detection and Response)?
As cyber threats are increasing in sophistication, the number of endpoints and attack surface vectors are evolving. XDR technology was built with multiple network components in mind.
It removes threats and fixes damages but offers more enhanced visibility than EDR solutions. XDR offers diverse defenses and is an excellent choice for organizations are are designing a dynamic security strategy.
Key Features of XDR
- XDR uses multiple threat detection methods and scans various attack surfaces and vectors. XDR technologies protect cloud apps, endpoints, SaaS providers, and others. They use multiple layers of protection across several security points, all accessible via a single platform.
- XDR delivers centralized access to various security tools such as IAMs, CSBs, network firewalls, and provides unified threat management capabilities. It essentially centralizes security tooling and supports a blend of human investigation and automated responses.
Difference between EDR and XDR
Both EDR and XDR are designed to replace traditional security solutions and provide automated responses to threats. Although they are similar in many ways, they have their differences.
Follow are the critical differences between EDR and XDR solutions:
| Feature | EDR (Endpoint Detection and Response) | XDR (Extended Detection and Response) |

| Identity and Access Management Support | May not support identity and access management systems | Supports identity and access management systems, including Active Directory, Azure AD, and more |
| SIEM System Support | May not support SIEM systems | Supports SIEM systems, including Splunk, ELK, and more |
| Cost | Typically less expensive than XDR solutions | Typically more expensive than EDR solutions due to the additional data sources and advanced analytics |
EDR vs XDR: Key Differences
- EDR focuses on endpoint devices (laptops, desktops, servers, and mobile devices) to detect and respond to malware, ransomware, and other types of attacks. XDR extends the scope of EDR by incorporating data from multiple sources, including network traffic (NGFW, IDS/IPS, etc.), cloud and SaaS applications (e.g., Office 365, AWS, Azure), email and messaging platforms, Identity and access management systems (IAMs), and other security information and event management (SIEM) systems.
- EDR solutions install an agent on each endpoint device to collect and analyze data, such as system logs, network traffic, and file system activity. XDR solutions provide a more comprehensive view of the attack surface, enabling detection and response to threats that may not be visible at the endpoint level alone.
- EDR platforms rely on signature-based detection, behavioral analysis, and machine learning algorithms to identify potential threats. XDR solutions often employ advanced analytics, machine learning, and artificial intelligence to identify patterns and anomalies across multiple data sources.
When to choose XDR and EDR?
You can choose EDR when:
- Your organization has a relatively small to medium-sized IT infrastructure, and most of your threats are endpoint-based (e.g., malware, ransomware).
- You have a limited budget and want a more cost-effective solution for endpoint security.
- You prioritize containment and remediation of endpoint-based threats and don’t need advanced analytics or threat-hunting capabilities.
- Your organization has a strong endpoint security posture, and you’re looking to enhance your existing endpoint security controls.
You can choose XDR when:
- Your organization has a large, complex IT infrastructure, and you need to detect and respond to advanced threats that may not be visible at the endpoint level alone.
- You have a high-risk environment, such as a financial institution, healthcare organization, or government agency, and need to detect and respond to sophisticated threats.
- You want to gain real-time visibility into your attack surface and detect threats across multiple data sources, including network traffic, cloud and SaaS applications, email, and identity and access management systems.
- You need advanced analytics, machine learning, and artificial intelligence to identify patterns and anomalies, and want to leverage threat-hunting capabilities to identify unknown threats and vulnerabilities.
- You’re looking for a solution that can integrate with your existing security tools and provide a single pane of glass for incident response and threat hunting.
You can choose both XDR and EDR if:
- If you have a mix of endpoint-based and advanced threats, consider implementing both EDR and XDR solutions to provide comprehensive threat detection and response capabilities.
- You’re unsure which solution to choose, consider starting with EDR and upgrading to XDR as your organization’s threat landscape evolves.
Conclusion
The debate of what is EDR vs XDR will never end, but one thing is clear: XDR triumphs EDR by providing extended security coverage. EDR is great for organizations with a limited budget that requires limited visibility. For organizations that are growing or scaling up, XDR will prove to be more valuable in the long run.
Hopefully, this answers your question of “What is XDR vs EDR” and gives you clarity on which tool to select. You can eliminate security silos and enhance your architecture by using a mix of both.
