EDR Tools: The Complete List for Security Teams in 2026

EDR tools in 2026 span enterprise commercial platforms, managed EDR services for SMBs, and genuine open-source options like osquery and Velociraptor, each fitting a genuinely different situation rather than competing head-to-head. If you have been handed a long list of names with no sense of which category actually applies to you, this guide sorts that out directly.

How to Use This EDR Tools List

This guide organizes EDR tools by the actual decision they answer, not simply an alphabetical vendor roundup. Enterprise commercial platforms suit organizations with dedicated security staff and budget for premium licensing. Managed EDR suits businesses without that internal capacity. Open-source tools suit teams with genuine technical expertise wanting flexibility and cost control, with real limitations worth understanding before committing to that path.

Work through the sections in order relevant to your own situation, rather than assuming every category applies equally to you, since the right EDR tool depends far more on your team’s actual capacity and budget than on any single feature comparison.

Enterprise Commercial EDR Platforms

CrowdStrike, SentinelOne and Microsoft Defender for Endpoint represent the current leading enterprise commercial EDR platforms, each combining behavioral detection, automated response capability, and centralized management across large device fleets. These platforms typically cost $50 to $150 per endpoint annually at enterprise scale, reflecting the depth of threat intelligence, continuous updates and support included.

These platforms genuinely suit organizations with dedicated security staff capable of operating sophisticated detection and response tooling directly, or organizations layering a managed service on top of the underlying platform technology. Choosing between them depends on your existing licensing ecosystem, your team’s operational capacity, and which specific architectural strengths, cross-domain correlation, autonomous remediation, ecosystem bundling, matter most for your own environment.

Managed EDR for SMBs and MSPs

Managed EDR combines underlying EDR technology with a provider’s 24/7 human-monitored SOC, closing the staffing gap that makes enterprise platforms genuinely difficult for smaller teams to operate effectively on their own. Huntress is among the most widely adopted examples specifically built around this model, combining SentinelOne’s underlying detection engine with continuous human monitoring, triage and remediation guidance.

This category suits small and medium businesses without dedicated internal security staff, and managed service providers building a security practice around reselling this exact combination to their own client base. The genuine value here is operational, not just technical: the same underlying detection capability enterprise platforms offer, but with the monitoring and response workload handled by someone with the dedicated capacity to actually watch it continuously.

Open-Source and Free EDR Tools

Genuine open-source options exist for teams with the technical expertise to operate them directly, without ongoing commercial licensing costs. OpenEDR, maintained by Xcitium, is a genuinely open-source EDR agent providing kernel-level telemetry collection, offering a free alternative to commercial licensing for teams comfortable managing that infrastructure themselves.

Wazuh operates as a unified, freemium XDR and SIEM platform, offering both a genuinely free open-source version and a paid commercial tier with additional support and features, running across Linux, Windows, macOS and several other operating systems through its own agent architecture. These tools eliminate licensing costs entirely or substantially, but they shift the operational burden, deployment, tuning, continuous monitoring, directly onto your own team, exactly the labor cost commercial and managed options exist specifically to absorb on your behalf.

osquery vs Velociraptor: Which One, and When

These two tools get frequently grouped together as interchangeable open-source options, when they actually represent genuinely different architectural approaches worth distinguishing precisely before choosing either one.

osquery is an open-source operating system instrumentation framework, exposing your operating system as a queryable, SQL-like relational database. It provides efficient, flexible querying of processes, files, network connections and other system state, but osquery alone has no native client-server architecture for managing a fleet of endpoints at scale, meaning you need additional infrastructure, commonly Fleet, layered on top to genuinely operate osquery across many devices simultaneously. It is fundamentally a visibility and query tool, not a complete detection and response platform on its own.

Velociraptor, built specifically by digital forensics and incident response experts, takes a genuinely more comprehensive approach. It includes a full client-server architecture with a graphical interface out of the box, uses its own Velociraptor Query Language for defining custom forensic artifacts, and deliberately pushes parsing and analysis work to the endpoint itself rather than the central server, making it considerably faster and less resource-intensive at scale than osquery alone. Velociraptor can even deploy and incorporate osquery agents within its own broader framework, extending rather than replacing osquery’s own capability. In one documented pilot comparison across 500 endpoints hunting for lateral movement activity, Velociraptor surfaced results in roughly two minutes, compared to osquery’s seven minutes for the equivalent task, with osquery additionally missing some transient system handles Velociraptor’s approach captured.

The practical choice comes down to scope. Choose osquery specifically when you need lightweight, flexible querying and already have or are building your own fleet management infrastructure around it. Choose Velociraptor when you need genuine, comprehensive digital forensics and incident response capability out of the box, particularly for active investigation and threat hunting at scale, without building that infrastructure yourself first. Here is the honest limitation worth stating directly for both: neither tool genuinely replaces a commercial EDR platform for continuous, automated monitoring and response. Most organizations still rely on dedicated EDR platforms specifically for that ongoing detection and automated response capability, using osquery or Velociraptor as complementary investigation and visibility tools rather than a full substitute.

Elastic Security: A Genuine Open-Source XDR Alternative, With Real Trade-Offs

Elastic Security combines Elastic’s own broader search and analytics stack with endpoint security capability, offering genuine open-source availability alongside paid commercial tiers, correlating endpoint telemetry with logs and other data sources across your environment rather than treating endpoint visibility in isolation.

This positions Elastic Security as a genuine, credible open-source-adjacent alternative to commercial XDR platforms specifically, since its underlying architecture already handles broad data correlation as its core competency, not an add-on feature. The real trade-off worth understanding directly: Elastic Security’s flexibility and correlation depth come with genuine operational complexity, deploying, tuning and maintaining the broader Elastic Stack requires meaningfully more technical expertise than a turnkey commercial EDR platform, and the free, open-source tier lacks some of the managed threat intelligence and support commercial vendors bundle directly into their pricing. Teams with genuine Elastic Stack expertise already in-house find this a legitimately powerful, cost-effective option. Teams without that existing expertise often find the operational overhead offsets much of the licensing savings this option otherwise offers.

Linux-Specific EDR Coverage

Linux endpoint coverage genuinely varies in depth across commercial vendors, worth checking directly rather than assuming parity with Windows and macOS support. Some enterprise platforms offer full-featured Linux agents matching their Windows capability closely, while others provide considerably lighter Linux coverage, focused more on basic telemetry than the deep behavioral detection available on other operating systems.

This matters directly for organizations running meaningful Linux infrastructure, servers, containers, cloud workloads, since assuming your chosen platform’s marketing materials describe equivalent coverage across every operating system without checking specifically often reveals a genuine gap only after deployment. Open-source options like Wazuh and OpenEDR both explicitly support Linux as a first-class platform, worth considering specifically for Linux-heavy environments where a commercial vendor’s own Linux agent has historically lagged behind their Windows offering. Confirm directly, before committing to any platform, exactly which Linux distributions are supported and what specific detection capabilities are genuinely available on Linux versus advertised generally across the platform’s marketing materials.

Adjacent Tool Categories Worth Knowing

Several related tool categories complement EDR without being EDR themselves, worth knowing to avoid confusing adjacent categories with the tools this guide has covered directly. Network Detection and Response, NDR, monitors network traffic itself rather than individual endpoints, catching unmanaged devices and encrypted traffic patterns EDR alone cannot see. SIEM platforms correlate log data across your broader environment, network, cloud, applications, alongside endpoint telemetry, providing network-wide pattern detection EDR’s endpoint-only view cannot achieve alone.

Adversary emulation tools, distinct again, simulate real attacker techniques deliberately against your own environment specifically to test whether your existing detection stack, EDR included, actually catches them, functioning as a validation exercise rather than an ongoing protective tool itself. Understanding where each of these categories fits relative to EDR specifically prevents the common mistake of expecting any single tool, however capable, to cover ground genuinely outside its own intended scope.

Where Does Each Category Fit Cyber Essentials?

NCSC’s Cyber Essentials scheme requires malware protection as one of five core technical controls, satisfied through any one of three approved approaches: anti-malware software, application allow-listing, or sandboxing. Baseline antivirus, considerably simpler than any EDR platform covered in this guide, is explicitly confirmed as sufficient to meet this specific requirement, including for Cyber Essentials Plus in many environments.

This means every category covered throughout this guide, enterprise commercial platforms, managed EDR, and genuine open-source options alike, exceeds what Cyber Essentials itself mandates as a baseline. Cyber Essentials does not require EDR at all, meaning your choice among the categories covered here should be driven by your actual risk profile and operational capacity, not by compliance requirements alone. Cyber Security Solutions Ltd routinely helps organizations understand this exact distinction, since a business achieving Cyber Essentials certification with basic antivirus is fully compliant while potentially remaining considerably more exposed than any EDR category in this guide would leave them.

Conclusion

Choosing the right EDR tool from this list depends far more on your team’s actual operational capacity than on any single feature comparison between the names covered here. Start by honestly identifying which category, enterprise commercial, managed, or open-source, genuinely matches your current staffing and budget reality.
