EDR vs XDR vs SIEM

Cyber crimes begin at the endpoint, such as phishing emails, hacking etc. which creates a starting foothold on a pc and expands across the network from there. The importance of the endpoint to an enterprise cybersecurity strategy has only increased. The EDR, XDR and SIEM are the solutions which are designed to provide automated threat detection and response through data visibility by using threat intelligence and data analytics.

EDR- Endpoint Detection and Response

This solution is designed to provide state of the art protection for corporate endpoints. These solutions provide multi-layer, fully integrated endpoint protection. Real-time continuous monitoring is combined with data analytics to detect threats, and automated, rule-driven response enables rapid mitigation of detected threats.

XDR – Extended Detection and Response

It is designed to simplify enterprise network security management. XDR solutions integrate security visibility across an organization’s entire infrastructure, including endpoints, cloud infrastructure, mobile devices, and more.

SIEM

SIEM collects, aggregates, analyzes and stores large volumes of log data across the enterprise

All the above three solutions designed to prevent systems from cyberattacks it provides cybersecurity. Solution’s goal is to provide deep visibility into a particular endpoint.

EDR vs XDR

Both are designed to replace legacy, reactive approaches to cybersecurity. As a result, EDR and XDR solutions are very much similar in several ways, such as:

• Responsive in Rapid Threat: EDR and XDR both support automated threat detection and response. This enables an organization to minimize the cost, impact, and damage caused by a cyberattack by preventing or rapidly remediating it.
• Preventative Approach: Traditional security solutions are often concentrated on detecting and remediating ongoing threats. EDR and XDR attempt to prevent security incidents by collecting in-depth data and applying data analytics and threat intelligence to identify threats before they occur.
• Supportive in Threat Hunting: Threat hunting enables proactive security by allowing analysts to identify and remediate potential security issues before they are exploited by an attacker. EDR and XDR provide deep visibility and easy access to data, which aids threat hunting efforts.
• Solution Integration: EDR solutions can provide “best in breed” protection for endpoints, and an organization may be able to manually integrate them with an array of point solutions. XDR is designed to provide integrated visibility and threat management within a single solution, dramatically simplifying an organization’s security architecture.
• Focus: EDR is focused on protecting the endpoint, providing in-depth visibility and threat prevention for a particular device. XDR takes a wider view, integrating security across endpoints, cloud computing, email, and other solutions.

EDR VS SIEM

EDR and SIEM are different solutions but they are complementary to each other and work well together, especially in a managed solution. A SIEM that is performing at peak performance should outperform EDR in detection. Detection is the key to SIEM. SIEM, the use case for collecting all this data was typically compliance-driven — likely PCI DSS, ISO 27001 or a government-imposed best practice. These requirements typically demanded log data collection at a general information level from across the environment being monitored.

Organizations have many different security and management tools, being able to bring data from those tools — as well as directly from infrastructure itself — into a single platform enables that data to be used in many useful ways. This includes highlighting attacker techniques aligned to the Mitre Attack framework, surfacing multiple related activities not evident through single purpose tooling, and providing a solid platform for threat hunting, incident response and general operational and risk management.

XDR vs SIEM

SIEM, both by its very nature and evolution, is well suited to a wide variety of use cases, and it remains the central platform of choice for organizations that need to address compliance, operational and security use cases.

XDR is an emerging concept with a definition that is still taking shape. Some consider XDR a logical evolution from either NDR or EDR, which probe very deeply into endpoint and network activity and generate detection information that is highly detailed and voluminous. The XDR concept builds on this granularity, focusing on a narrow set of data sources, from which it resolves an extremely detailed level of information about activity taking place typically in the cloud or at the endpoint, network or user level. This detailed information is used to detect threats at the point of interaction with the environment with a high degree of accuracy.

All these solutions are all best in their respect and it will be difficult to choose which one is best in between three of this that is EDR, XDR and SIEM. We can help you brainstorm best solutions to prevent cyberattacks, feel free to connect with us.
