Explore effective strategies for mapping EDR to MITRE ATT&CK techniques and enhance
The threat landscape now includes fileless attacks, zero-day exploits, and sophisticated lateral movements that evade signature based defenses. Basic antivirus or simple endpoint agents leave gaps that adversaries exploit.
When today’s attackers bypass static defenses or hide in legitimate processes, security teams struggle with delayed alerts, false positives, and lengthy investigations. That fumbling window can lead to data loss, system encryption, or persistent footholds.
This article highlights six critical capabilities of a modern EDR solution—from real-time endpoint threat detection and behavioral analytics, to automated response, built-in threat hunting, cloud native scalability, and XDR integration—so you can evaluate and choose an EDR that keeps pace with advanced threats.
Stealthy attacks often unfold in seconds, leaving no room for delayed alerts. A modern EDR ingests kernel level events, process launches, registry modifications, and file operations as they happen. Imagine a script injection attempt via PowerShell—caught at the moment of execution rather than discovered hours later. Immediate visibility lets you block malicious behavior before it spreads beyond the endpoint.
Signature databases struggle to keep pace with polymorphic malware and living off the land techniques. By learning normal patterns—such as typical application launches, user access times, and network connections—behavioral analytics spot deviations that signify compromise. For example, if a developer workstation suddenly starts spawning command-line processes at midnight, that anomaly becomes a clear signal to investigate. Context rich detection captures threats that traditional scanners miss.
Manual containment processes introduce delays and risks of human error. Automated playbooks ensure that when a threat is confirmed—such as a new service creation or unauthorized code injection—the EDR isolates the host, terminates malicious processes, revokes compromised credentials, and gathers forensic data without waiting for human approval. This consistency slashes dwell time and lets teams focus on high value analysis rather than routine tasks.
Reactive alerts rarely catch every campaign. Proactive threat hunting empowers teams to search endpoint telemetry—covering processes, registry changes, network calls, and file events—for Indicators of Attack (IOAs) or new Indicators of Compromise (IOCs). An intuitive hunting interface lets analysts pivot on artifacts like suspicious DLL loads or unusual parent child process chains, uncovering hidden adversaries before damage escalates.
Modern environments span on prem, cloud, and edge. EDR agents must deploy rapidly, consume minimal resources, and update seamlessly. A cloud native architecture provides centralized management, elastic scaling to protect thousands of endpoints, and integrated analytics without heavy on prem infrastructure. This ensures new devices—whether remote laptops or serverless instances—gain immediate protection at scale.
Endpoint threats rarely occur in isolation. Coordinated attacks traverse network, cloud, email, and identity layers. When EDR telemetry feeds into an XDR platform, alerts correlate across these domains—revealing full attack paths. For instance, a suspicious PowerShell event on an endpoint triggers cross correlation with an unusual network connection, accelerating root cause analysis and orchestrated response across multiple security controls.
Every second matters once a breach begins. Immediate detection and automated isolation ensure threats are neutralized before they can move laterally or exfiltrate data. That rapid containment transforms potential multi hour compromises into incidents measured in minutes.
Behavioral analytics catch novel threats—fileless malware, zero–day exploits, and living-off-the-land attacks—that signature-based tools overlook. This adaptive detection reduces blind spots and strengthens resilience against emerging attack techniques.
Automated response playbooks apply the same approved actions every time—regardless of shift changes or workload spikes. Uniform containment reduces human error, ensures compliance with policy, and builds organizational confidence in the tool’s reliability.
Built–in hunting capabilities let you detect dormant threats that evade automated controls. By querying stored telemetry for new IOCs or anomalous patterns, you maintain an active defense posture—identifying hidden campaigns before they trigger alerts.
Cloud native EDR adapts to growing endpoint counts and diverse deployments—from IoT to virtual desktop environments—without adding management complexity or degrading device performance. That agility supports digital transformation efforts securely.
Integration with XDR breaks down data silos. Shared context across endpoints, networks, and cloud workloads accelerates investigations and automates multi–vector responses—such as blocking malicious domains networkwide after detecting a related endpoint threat—amplifying your security ROI.
Fidelis Endpoint® captures kernel level events, process executions, registry changes, and network calls in real time. Its Continuous Monitoring Engine Surfaces Indicators of Attack instantly, supporting real–time endpoint threat detection and enabling immediate investigation and containment.
With machine learning–driven baselining, Fidelis establishes normal behaviors for every endpoint—applications used, typical access hours, and network interactions. Deviations, like an unusual PowerShell invocation, trigger high-fidelity alerts under behavioral analytics EDR frameworks.
Fidelis playbooks automatically isolate compromised hosts, terminate malicious processes, revoke user sessions, and collect forensic snapshots. These automated EDR response actions enforce consistent containment policies and eliminate manual delays.
Fidelis offers a query able hunting console with prebuilt queries for common IOAs and IOC integration. Analysts can pivot on artifacts—such as DLL loads or command line arguments—to uncover stealthy threats. This integrated EDR threat hunting capability removes dependence on separate tools.
Fidelis agents install rapidly with minimal footprint, communicating securely with cloud or on–prem consoles. The solution scales from dozens to tens of thousands of endpoints, ensuring consistent policy enforcement and updates for cloud native scalability.
Through open APIs and native connectors, Fidelis Endpoint feeds telemetry into the Fidelis Elevate XDR platform—correlating endpoint alerts with network, deception, and directory signals. This integration with XDR ecosystems enables comprehensive detection and coordinated response across your entire security stack.
Selecting a modern EDR solution hinges on six essential capabilities: real-time detection, behavior analytics, automated response, proactive hunting, scalable deployment, and XDR integration. These features form the bedrock of an adaptive, proactive defense capable of staying ahead of today’s advanced threats.
Fidelis Endpoint® delivers each capability natively—empowering you to detect sophisticated attacks quickly, contain them automatically, and hunt hidden intrusions efficiently.
