Although the general shift in detection and response has been toward managed tools, standalone EDR can be highly effective for organizations with mature security teams and established SOC operations. There are still several common EDR tools that are purely standalone, as well as many others that require higher-tier commitments to unlock SOC services. Let's take a look at what standalone EDR can do.

Capture endpoint telemetry

The best EDR tool examples are lightweight agents that record endpoint telemetry across key system activities, including:

• Process lineage: Which process spawned another (e.g., Word opening PowerShell)
• File events: The creation, modification, and deletion of files, especially in sensitive directories
• Registry events: Changes to system configuration keys (used for persistence)
• Network connections: Outbound connections from a process to an external IP or domain (e.g., an attacker's [command and control [C2] server](https://www.huntress.com/cybersecurity-101/topic/what-is-command-and-control-center))
• API calls: Interactions with the Windows API (used for process injection)

Flag suspicious behavior

Beyond logging events, EDR tools use behavioral analysis and machine learning to identify shady activity. Instead of looking for known signatures (like AV), EDR looks for modern techniques like LotL, where an attacker uses a legitimate tool to hide their activity—for example, PowerShell running an encoded script.

EDR can also detect unauthorized access to memory processes to steal passwords (i.e., credential dumping), attempts to move laterally (e.g., a workstation trying to connect to a server it never talks to), and persistence mechanisms (e.g., new "Run Keys" or scheduled tasks).

Give analysts data to investigate

When an alert triggers, EDR tools aggregate all related telemetry into a single timeline so investigators don't have to manually hunt through thousands of log entries. If your team has a security information and event management (SIEM) or XDR tool, this centralized platform will also correlate EDR signals with logs from across your environment.

Even without a SIEM, EDR will allow analysts to see where the suspicious activity started on the endpoint and what it touched. This is often enough to confirm if a threat is real or a false alarm.

For many organizations, the question isn't "why use EDR" but "how to use EDR." The greatest technical strength of EDR—its sensitivity—can also be an operational burden if your organization isn't equipped to handle it.

Because EDR is designed to catch the most subtle anomalies, it can frequently flag legitimate activity. With the sheer number of alerts, high potential for false positives, and the fact that different EDR tools provide varying levels of context for verification, internal security teams can quickly become overwhelmed. This can lead to missed alerts and analyst burnout.

EDR tools require careful tuning to reduce noise while maintaining vigilance. It can take many hours to develop, test, and deploy new detection rules and perform ongoing maintenance. This puts additional strain on security teams, many of which are already understaffed due to global talent shortages. According to ISC2, the cybersecurity workforce gap stands at 4.8 million, and 58% of survey respondents say staffing shortages put their organizations at significant risk.

Detecting malicious activity is only half the battle. If no one is around to respond to alerts, the best detection tools in the world won't help you. Every minute an attacker is inside your environment is more time they have to establish persistence, escalate privileges, move laterally, and target high-value data.

However, building a 24/7 SOC internally isn't feasible for most organizations. That's why threat actors often launch attacks on weekends, after hours, or around holidays, when response may be delayed. With the speed of modern attacks, waiting until Monday morning to respond to a weekend alert could be too late.

Managed EDR tools essentially make enterprise-level threat detection and response capabilities available to businesses of all sizes. Instead of an EDR tool that merely detects anomalies, you get a 24/7 SOC that continuously monitors and responds to alerts. This can significantly reduce the mean time to respond (MTTR)—often from hours or days to minutes—a crucial factor for containing the blast radius of an attack.

Managed EDR providers can quickly isolate a compromised machine and terminate malicious processes, stopping threats from spreading. The SOC can then send your team a detailed incident report with actionable remediation steps.

With a managed SOC, internal teams don't typically receive raw alerts, only validated, high-confidence alerts that tell the story of an attack. This helps prevent alert fatigue and frees internal teams to work on other tasks. Having a team of experts doing the heavy lifting of detection and response also allows IT generalists to manage many threats with easy-to-follow remediation recommendations.

Crucially, managed EDR solves the financial and practical challenge of building an internal SOC. For a mid-sized business, maintaining 24/7 detection and response typically requires 8–12 full-time analysts, plus additional management and engineering support. The high demand for cybersecurity talent means that the largest organizations are willing and able to outbid competitors for available experts. That can effectively price out smaller businesses from staffing an adequate team. Add to this the cost of building and maintaining a custom EDR tool or licensing one, plus other infrastructure and operations investments, and the total cost of an internal SOC is out of reach for most organizations.

Huntress Managed EDR gives organizations the benefits of managed endpoint detection without leaving them alone to sort through all the alert noise. Unlike many other EDR platforms, Huntress Managed EDR comes with full features and is backed by a 24/7 SOC at one predictable price—no tiered pricing or add-ons (check out our EDR tool comparisons).
