What is EDR and What are EDR Tools?

An effective EDR solution should help your security team identify, collect and analyze cyberthreat data. Advanced solutions utilize artificial intelligence (AI), machine learning and deep learning techniques to correlate information from multiple sources in your network–including antivirus software and next-generation firewalls.

EDR tools typically use agents on each endpoint device to monitor activity and collect data, taking up minimal resources so as not to affect computer performance. Additionally, the best solutions offer risk ratings for each alert as well as threat hunt capabilities to help analysts investigate potential attacks.

Some solutions provide automated response capabilities, such as isolating suspect devices or one-click attack blocking, that are particularly beneficial to small businesses with limited IT security staff or for whom a comprehensive security suite would be too cost prohibitive. Other features worth keeping in mind include:

Top 6 free EDR Tools

EDR tools provide powerful threat hunting/threat remediation technology; however, their high cost may make them unaffordable to many companies. Luckily, there are a few free source EDR tools you can utilize to bolster endpoint security without breaking the bank.

Multiple vendors provide EDR solutions, some of which include response capabilities. Some solutions combine prevention, detection and remediation into an all-in-one suite; other have separate components for each function; still others allow software as a service deployment.

Some of the top EDR software offers behavior-based analysis, predictive analytics and forensics to detect unknown threats by analyzing activity on devices and searching for patterns characteristic of malicious behaviour.

Some more expensive solutions offer value-adding features, including centralized management, threat hunting and automated response. Some also integrate with third-party threat intelligence feeds so your security system has access to more behaviors and threats for investigation – helping reduce false positives while saving time investigating alerts.


OSSEC – This open source host-based intrusion detection system (HIDS) offers standard security features like file integrity monitoring, log monitoring, rootkit detection and auditing. Furthermore, its real time behavior analytics feature helps detect threats as they arise in real time.

Many EDR solutions integrate with third-party threat intelligence feeds to augment their capabilities in detecting suspicious activities such as malware, IoCs and more – helping IT teams reduce alerts while even uncovering new threats or zero-day attacks.

CrowdStrike Falcon earned high scores across independent tests, particularly detection and response capabilities. It offers affordable options for small businesses, while more advanced features like vulnerability management and automated remediation cost extra; CrowdStrike also offers a free trial period; for pricing details contact them directly. It is essential that IT and security teams identify which capabilities are essential when selecting an EDR tool; new teams may require guidelines on prioritizing risks while communicating alerts while more experienced teams may require customized features tailored more closely to their business requirements.

2. OpenEDR

OpenEDR is an invaluable tool for organizations seeking to enhance their endpoint security. With its wide range of features and user-friendly interface, OpenEDR provides a powerful solution for monitoring, detecting, and responding to potential threats.

Effective EDR relies on combining massive amounts of endpoint telemetry with intelligence and contextual data in order to detect threats before they cause data breaches. Successful detection and response require adopting a behavioral approach that seeks indicators of compromise while attributing them back to an attacker.

Contextual information allows security teams to better triage alerts by considering threats’ level of severity and likelihood of impact, eliminating false positives that sap team resources and slow response times. EDR solutions help organizations mitigate damage quickly by quickly detecting attacks, stopping them in their tracks with robust containment capabilities, and recovering quickly afterwards.

Hive is used by various organizations such as non-profits universities hospitals creative teams among many others.

4. Osquery

Osquery is an open source tool designed to increase endpoint visibility and system information. It can either be deployed as a central logging solution, or run interactively with scheduled queries on its command-line interface. Furthermore, its OS-level data are presented as virtual SQL tables to facilitate flexible querying capabilities.

Osquery provides valuable data collection capabilities; however, its processing requires considerable storage space and bandwidth resources. Furthermore, Osquery produces large volumes of information that may make identifying valuable insight a difficult process; many organizations channel Osquery data through SIEM repositories like Elastic Search or Splunk to access all this valuable insight quickly and efficiently.

Some organizations opt for an independent build-your-own approach, taking responsibility for every element of Osquery themselves from agent deployment and configuration to accessing data. Others prefer working with vendors who offer fully featured, ready-to-use Osquery solutions like CrowdStrike Falcon. CrowdStrike Falcon provides all the advantages of Osquery with ease of use, impressive security scores, and automated remediation on compromised machines – something many organizations find more viable options than DIY approaches.
