EDR / XDR -- 12 Free Tools

EDR & XDR Learning Tools

Practical, reference-grade tools covering every aspect of endpoint detection and response. Built for Indian cybersecurity professionals working with any EDR platform.

Endpoint detection and response

EDR and XDR — why endpoint telemetry is the SOC's most important data source.

Endpoint Detection and Response (EDR) tools run as agents on individual endpoints — workstations, servers, and laptops — and record detailed telemetry about everything happening on that device: every process that starts, every network connection it makes, every file it creates or modifies, every registry key it touches. This telemetry is sent to a central platform where security teams can investigate threats, run hunting queries across all endpoints simultaneously, and remotely isolate compromised devices. EDR has largely replaced traditional antivirus because AV relies on file signatures to detect known malware, while EDR detects malicious behaviour regardless of whether the malware has been seen before.

XDR (Extended Detection and Response) extends EDR beyond the endpoint to correlate telemetry from email, network, cloud, and identity sources in a single platform. The distinction matters for Indian organisations making deployment decisions: EDR provides excellent endpoint visibility and is the right starting point, while XDR adds correlation across sources that can detect attacks that involve multiple vectors — a phishing email that leads to credential theft that leads to cloud service abuse, for example.

The most widely deployed EDR platforms in Indian enterprises are Microsoft Defender for Endpoint (bundled with Microsoft 365 E5 licensing), CrowdStrike Falcon, and SentinelOne Singularity. The tools on this page provide detection rules, configuration references, and response procedures for all three platforms, with MITRE ATT&CK mapping throughout.

Frequently asked questions — EDR and XDR

What is the difference between EDR and traditional antivirus?

Traditional antivirus works by comparing files against a database of known malware signatures. If a file's hash or byte patterns match a known malicious file, it is blocked. EDR works by monitoring behaviour — what a process does, not what it looks like. A process that injects code into another process, reads LSASS memory, or makes outbound connections immediately after a document is opened exhibits malicious behaviour that EDR detects regardless of whether the specific malware has been seen before. This makes EDR effective against novel malware, fileless attacks, and living-off-the-land techniques that use legitimate Windows tools.

What is network isolation in EDR and when should you use it?

Network isolation is an EDR capability that cuts an endpoint off from all network communication while maintaining the EDR agent's own connection to the cloud platform. It is used during active incident response to contain a compromised endpoint — preventing the attacker from issuing further commands, preventing malware from spreading laterally, and preventing data exfiltration — while keeping the endpoint powered on and accessible to the security team for remote forensic investigation. Network isolation should be triggered simultaneously across all known compromised endpoints, not sequentially — sequential isolation gives attackers time to destroy evidence on remaining connected systems.

What is a MITRE ATT&CK detection rule in EDR context?

EDR platforms allow security teams to write custom detection rules targeting specific MITRE ATT&CK techniques. For example, a rule targeting T1059.001 (PowerShell execution) might fire when powershell.exe is launched with -EncodedCommand or -ExecutionPolicy Bypass flags by a parent process that is not a legitimate management tool. The MITRE ATT&CK to EDR Rule Mapper on this platform provides pre-built detection rules for CrowdStrike Falcon, SentinelOne, and Microsoft Defender for Endpoint, covering the techniques most commonly used by APT groups targeting India.

What EDR coverage is required under Indian regulations?

The RBI IT Framework for banks and NBFCs requires end-point security solutions on all user devices and servers. RBI's CSCRF (Cyber Security and Cyber Resilience Framework) specifically references EDR capability as a required control for regulated financial entities. SEBI's CSCRF for market infrastructure institutions has similar requirements. CERT-In Directions 2022 require that organisations be able to detect and report the 20 notifiable incident types — adequate EDR coverage is practically necessary to achieve this detection capability for endpoint-based incidents, which constitute the majority of the notifiable categories.
