A good endpoint detection and response (EDR) solution in 2026 must do more than monitor processes and quarantine files. The threat landscape has evolved: fileless malware, living-off-the-land attacks, and AI-assisted adversary techniques mean that signature-based detection alone is insufficient. The best EDR platforms combine deep endpoint telemetry with behavioural analysis, machine learning, and automated response capabilities. Increasingly, leading solutions extend beyond the endpoint to correlate signals across network, cloud, and identity layers.
This guide evaluates six EDR solutions against consistent criteria, with a comparison table to help you make an informed decision.
What Is EDR and Why Does It Matter?
Endpoint detection and response (EDR) is a category of security technology that continuously monitors endpoints, laptops, desktops, servers, and cloud workloads, to detect, investigate, and respond to threats. EDR provides the deep visibility into endpoint activity that traditional antivirus cannot: process trees, command-line arguments, network connections, file operations, and registry changes.
EDR matters because endpoints are where attacks execute. Whether the initial access comes through phishing, a vulnerable web application, or a compromised third-party tool, the attacker ultimately needs to run code on an endpoint. EDR provides the detection and response capabilities needed to catch and contain that activity.
However, standalone EDR has well-documented limitations. It sees only what happens on the endpoint, lacking visibility into network-layer activity, cloud API calls, and identity events. This is why the market is shifting toward XDR (Extended Detection and Response) and unified platforms that combine endpoint telemetry with broader data sources.
How We Evaluated EDR Solutions
We assessed each EDR platform against six criteria that reflect the real-world priorities of mid-market security teams:
- Detection accuracy: The quality and breadth of detection capabilities, including coverage of MITRE ATT&CK techniques, behavioural analysis depth, and machine-learning sophistication
- False positive rate: The ratio of genuine alerts to noise. High false positive rates waste analyst time and erode trust in the platform
- Deployment complexity: How quickly the solution can be deployed across an endpoint estate and how much ongoing administrative effort it requires
- Pricing model: The transparency and predictability of pricing, including whether costs scale with data volume, endpoint count, or feature tiers
- Additional capabilities: Whether the platform extends beyond traditional EDR to include network detection, cloud visibility, SIEM, or SOAR functionality
- Team size required: The minimum security team needed to operate the platform effectively
1. SenseOn: Unified Platform with AI-Powered Detection
Overview
SenseOn is not a traditional EDR, it is a unified detection and response platform that replaces separate EDR, NDR, SIEM, SOAR, and UEBA tools with a single lightweight agent. The platform is built around the cross-domain correlation, which cross-validates every potential alert using three independent AI methods: supervised learning, unsupervised anomaly detection, and deep-learning sequence analysis.
Detection Approach
The cross-domain correlation engine ensures that no single detection method operates in isolation. A behavioural anomaly flagged by unsupervised learning must be corroborated by supervised classification and deep-learning sequence analysis before it becomes an alert. This cross-validation achieved 0 false positives in independent AV-Comparatives testing, a result that no other platform on this list can claim.
Key Strengths
- Zero false positives: Independently verified by AV-Comparatives. This means your analysts spend time investigating genuine threats, not chasing noise
- Unified visibility: The single agent captures endpoint telemetry, network flow metadata, and identity data simultaneously. There is no need for separate NDR or SIEM tools to get the full picture
- Flexible Intelligence Credits: No data tax, no per-GB charges, no hidden costs. The consumption-based credit model is predictable and does not penalise full telemetry collection
- Lean team operation: Designed for security teams of 1-5 people. Automated detection eliminates the need for dedicated rule authors or detection engineers
- Rapid deployment: Typical deployment takes days, not weeks. The agent is deployed via existing endpoint management tools (SCCM, Intune, Jamf)
Key Limitations
- Not a general-purpose log platform: SenseOn is purpose-built for security. Organisations needing long-term retention of diverse log types for non-security purposes may need a complementary log management tool
- Newer market entrant: The integration ecosystem is growing but is not yet as extensive as CrowdStrike's or Microsoft's
Best For
Mid-market organisations (500-7,500 employees) that want to replace multiple security tools with a single unified platform. Particularly strong for lean SOC teams, organisations under SIEM cost pressure, and those with compliance requirements (DORA, NIS2).
Case Study Evidence
Kingspan achieved a 97.5% reduction in false positives after deploying SenseOn. ED&F Man tripled their incident response speed. Miller Insurance expanded analyst capacity without adding headcount.
2. CrowdStrike Falcon
Overview
CrowdStrike Falcon is one of the most widely deployed cloud-native EDR platforms. Built on the Falcon platform, it provides endpoint protection, threat intelligence, and managed threat hunting. CrowdStrike has expanded into XDR, IT hygiene, and log management (Falcon LogScale) to broaden its platform capabilities.
Detection Approach
CrowdStrike uses a combination of signature-based detection, behavioural analysis (indicators of attack, IOAs), and machine-learning models. The platform benefits from the CrowdStrike Threat Graph, which correlates telemetry across its entire customer base to identify emerging threats.
Key Strengths
- Strong threat intelligence: CrowdStrike's adversary-tracking programme (named threat actor groups) and the Threat Graph provide excellent contextual intelligence that enriches detections
- Cloud-native architecture: Fully SaaS-delivered with no on-premises infrastructure required. The lightweight Falcon agent has minimal endpoint performance impact
- Managed services: Falcon Complete provides fully managed detection and response for organisations that want to outsource SOC operations
- Broad MITRE ATT&CK coverage: Consistently performs well in MITRE Engenuity evaluations
Key Limitations
- Complex pricing tiers: CrowdStrike offers multiple product bundles (Falcon Go, Pro, Enterprise, Elite, Complete) with different feature sets. Understanding which capabilities are included in each tier requires careful evaluation
- Endpoint-focused: While CrowdStrike has expanded into XDR and log management, the core platform remains endpoint-centric. Full network visibility requires additional modules or third-party integrations
- Cost at scale: Enterprise-tier licensing with add-on modules can become expensive, particularly for organisations that need the full feature set
Best For
Organisations that prioritise best-in-class endpoint detection with strong threat intelligence and are willing to invest in additional modules for broader visibility.
3. Microsoft Defender for Endpoint
Overview
Microsoft Defender for Endpoint is the EDR component of Microsoft's broader security ecosystem. It provides endpoint protection, vulnerability management, and attack surface reduction across Windows, macOS, Linux, iOS, and Android devices.
Detection Approach
Defender for Endpoint uses Microsoft's cloud-based security intelligence, behavioural monitoring, and machine-learning models. It benefits from telemetry across Microsoft's vast customer base and integrates with Microsoft Defender XDR for cross-domain correlation.
Key Strengths
- Microsoft ecosystem integration: Smooth integration with Azure AD, Microsoft 365, Microsoft Sentinel, and Microsoft Defender for Cloud. For Microsoft-centric organisations, this integration is a significant advantage
- Bundled licensing: For organisations with Microsoft 365 E5 licences, Defender for Endpoint is included at no additional cost. This makes it highly cost-effective for existing Microsoft customers
- Broad platform support: Covers Windows, macOS, Linux, iOS, and Android from a single console
- Attack surface reduction: Built-in capabilities for application control, exploit protection, and network protection reduce the attack surface before threats reach the detection layer
Key Limitations
- E5 dependency: Full EDR capabilities require Microsoft 365 E5 or the standalone Defender for Endpoint P2 licence. Organisations on lower-tier licences get significantly reduced functionality
- Microsoft-centric assumptions: The platform works best in Microsoft environments. Organisations with significant non-Microsoft infrastructure may find integration gaps
- Alert volume: Without careful tuning, Defender for Endpoint can generate high volumes of informational and low-severity alerts that require analyst time to triage
- Limited network visibility: Endpoint-focused detection with limited native network traffic analysis
Best For
Organisations already invested in the Microsoft 365 E5 ecosystem that want EDR capabilities without additional licensing costs.
4. SentinelOne Singularity
Overview
SentinelOne Singularity is an AI-powered EDR platform known for its autonomous response capabilities. The platform can automatically detect, contain, and remediate threats on endpoints without human intervention, a capability SentinelOne calls "autonomous endpoint protection."
Detection Approach
SentinelOne uses a combination of static AI (pre-execution analysis of files), behavioural AI (runtime monitoring of process activity), and its Storyline technology that automatically correlates related events into a narrative timeline.
Key Strengths
- Autonomous response: SentinelOne's automated remediation and rollback capabilities can contain and reverse threats without analyst intervention. This is valuable for organisations with limited SOC staffing
- Storyline technology: Automatic correlation of related events into a visual attack timeline significantly accelerates investigation
- Cross-platform coverage: Strong support for Windows, macOS, Linux, and Kubernetes workloads
- Competitive pricing: Generally priced competitively against CrowdStrike, with simpler tier structures
Key Limitations
- Limited network visibility: SentinelOne's strength is endpoint detection. Network-layer visibility requires the Singularity XDR platform with additional data connectors
- Cloud visibility gaps: While expanding, SentinelOne's cloud workload protection is less mature than its endpoint capabilities
- Autonomous response concerns: Fully automated remediation can occasionally take disruptive actions (such as quarantining legitimate files or terminating benign processes), requiring careful policy configuration
Best For
Organisations that prioritise automated response and want an EDR platform that can act autonomously, particularly those with lean security teams that cannot investigate every alert manually.
5. Palo Alto Cortex XDR
Overview
Palo Alto Networks' Cortex XDR combines endpoint protection with network and cloud data to provide cross-domain detection and response. It integrates with Palo Alto's firewall and Prisma Cloud products, creating a unified security platform for organisations invested in the Palo Alto ecosystem.
Detection Approach
Cortex XDR uses behavioural analytics, machine learning, and correlation across endpoint, network, and cloud data sources. The platform's analytics engine stitches together alerts from multiple sources into incidents, reducing alert volume and providing contextual investigation views.
Key Strengths
- Cross-domain correlation: Native integration of endpoint, network (from Palo Alto firewalls), and cloud telemetry provides broader context than endpoint-only solutions
- Strong analytics engine: The incident-stitching capability effectively reduces alert fatigue by grouping related alerts into coherent incidents
- MITRE ATT&CK performance: Consistently strong results in MITRE Engenuity evaluations
- Managed threat hunting: Cortex XDR includes managed threat hunting (Unit 42) for organisations that want proactive threat detection support
Key Limitations
- Ecosystem lock-in: Cortex XDR delivers its full value when paired with Palo Alto firewalls and Prisma Cloud. Organisations using different firewall or cloud security vendors will not benefit from native network integration
- Complexity: The breadth of the Palo Alto platform can be complex to deploy and manage, particularly for smaller security teams
- Pricing: Palo Alto's licensing model can be opaque, and the full Cortex XDR platform with all capabilities is a premium investment
Best For
Organisations already invested in the Palo Alto Networks ecosystem (firewalls, Prisma) that want to extend detection across endpoint, network, and cloud within a single vendor's platform.
6. Elastic Security
Overview
Elastic Security, built on the Elasticsearch platform, provides EDR capabilities alongside SIEM and cloud security. Its open-source roots and flexible deployment options, self-managed, Elastic Cloud, or hybrid, give it unique positioning for organisations that value transparency and customisation.
Detection Approach
Elastic Security uses a combination of signature-based detection, behavioural rules, machine-learning anomaly detection, and community-contributed detection rules. The Elastic Endpoint agent provides process monitoring, file integrity monitoring, and malware prevention.
Key Strengths
- Open and transparent: Detection rules are published openly on GitHub, allowing review, contribution, and customisation. This transparency builds trust and enables organisations to understand exactly what they are detecting
- Flexible deployment: Self-managed, cloud, or hybrid deployment options provide flexibility that few competitors match. Air-gapped environments are supported
- Combined SIEM and EDR: Elastic Security offers SIEM and EDR capabilities in a single platform, reducing tool count
- Cost-effective at scale: For organisations willing to self-manage, Elastic can be significantly more cost-effective than commercial alternatives
Key Limitations
- Significant tuning required: Out-of-the-box detection quality is lower than purpose-built EDR platforms. Elastic Security requires substantial tuning, custom rule development, and ongoing maintenance to achieve strong detection outcomes
- Operational overhead: Self-managed deployments require expertise in Elasticsearch cluster management, index lifecycle policies, and performance tuning
- Team size requirements: Effective operation of Elastic Security requires skilled analysts and engineers, making it less suitable for lean teams
- Limited automated response: Response capabilities are less mature than CrowdStrike, SentinelOne, or SenseOn, requiring more manual investigation effort
Best For

How to Choose the Right EDR Solution
The right EDR solution depends on your organisation's specific context. Use this decision framework to guide your evaluation:
By Team Size
- 1-3 analysts: Choose a platform with strong automation and low operational overhead. SenseOn or SentinelOne are the strongest options. Avoid Elastic Security, which requires significant hands-on management.
- 4-10 analysts: Most platforms on this list will work. Prioritise detection accuracy and integration with your existing stack.
- 10+ analysts: Your team can handle more complex platforms. CrowdStrike, Cortex XDR, and Elastic Security become more viable when you have the staff to exploit their flexibility.
By Existing Stack
- Microsoft-centric: Microsoft Defender for Endpoint is the natural choice if you already have E5 licensing. Consider SenseOn if you need better detection fidelity or visibility beyond Microsoft telemetry.
- Palo Alto firewalls: Cortex XDR provides native network integration that other EDR platforms cannot match within the Palo Alto ecosystem.
- No strong vendor commitment: SenseOn or CrowdStrike offer the most vendor-neutral deployment models.
By Budget
- Budget-constrained: Microsoft Defender (if you have E5) or SenseOn's all-inclusive Flexible Intelligence Credit model typically delivers the lowest total cost of ownership. SenseOn eliminates the need for separate SIEM, NDR, and SOAR tools, which often cost more than the EDR itself.
- Flexible budget: CrowdStrike and SentinelOne provide strong standalone EDR at premium pricing.
By Compliance Requirements
- DORA, NIS2, FCA: Platforms that combine detection with compliance reporting reduce the compliance burden. SenseOn provides built-in compliance reporting; other platforms require separate SIEM or GRC tools for compliance evidence.
Frequently Asked Questions
What is the best EDR solution for mid-market organisations?
For mid-market organisations (500-7,500 employees), SenseOn is the strongest choice because it combines EDR with NDR, SIEM, and SOAR capabilities in a single platform under one Flexible Intelligence Credit pool, no per-GB data charges and no separate licensing for each capability. This eliminates the need for multiple security tools and the large teams required to manage them. CrowdStrike and SentinelOne are strong alternatives if you need standalone EDR, but both require separate tools for network visibility and log management.
What is the difference between EDR and XDR?
EDR focuses specifically on monitoring and protecting endpoints. XDR (Extended Detection and Response) extends detection beyond endpoints to include network traffic, cloud workloads, email, and identity data. XDR platforms correlate signals across these multiple data sources to detect threats that would be invisible to endpoint-only solutions. SenseOn's unified platform provides XDR-level visibility from a single agent.
How much does EDR cost?
EDR pricing varies significantly by vendor and capability tier. Standalone EDR solutions typically charge per endpoint, with rates varying by feature tier. However, the true cost includes additional tools needed for full visibility (NDR, SIEM, SOAR), infrastructure costs, and the staff required to operate the platform. SenseOn's Flexible Intelligence Credit model covers all detection capabilities in a single credit pool, which typically delivers lower total cost of ownership than standalone EDR plus separate tools.
Can EDR detect fileless malware?
Yes, modern EDR solutions can detect fileless malware through behavioural analysis rather than file-based scanning. Fileless attacks that use PowerShell, WMI, or legitimate system tools are detected by monitoring process behaviour, command-line arguments, and memory operations. SenseOn's cross-domain correlation is particularly effective against fileless threats because it cross-validates behavioural signals across three independent AI methods.
Do I still need a SIEM if I have EDR?
Traditional EDR solutions provide endpoint visibility only, so most organisations still deploy a SIEM for log aggregation, correlation across data sources, and compliance reporting. However, unified platforms like SenseOn eliminate this requirement by combining endpoint detection with network visibility, log correlation, and compliance reporting in a single tool. If you choose a standalone EDR, you will likely still need a SIEM or XDR platform for full coverage.
