Microsoft Defender for Endpoint is the best overall choice for organizations already using Microsoft 365, Windows and Intune. It combines endpoint protection, EDR, vulnerability management, attack-surface reduction, automated investigation and response in the Microsoft Defender portal. Microsoft Defender for Business is the better fit for smaller organizations with up to 300 users.

The 2025 AV-TEST business endpoint test evaluated 18 products, but independent testing should support a buying decision rather than determine it on its own. Your existing security stack, operating systems, internal expertise and licensing model matter just as much.

The main alternatives are:

  • CrowdStrike Falcon for enterprise EDR and security operations.
  • SentinelOne Singularity Endpoint for automated response and ransomware rollback.
  • Sophos Endpoint for small and midsize businesses, MSPs and prevention-focused protection.
  • Bitdefender GravityZone for broad endpoint coverage and flexible packaging.
  • Palo Alto Cortex XDR for organizations already using Palo Alto security products.
  • ESET PROTECT for lightweight protection, mixed operating systems and cloud or on-premises management.

1. Microsoft Defender for Endpoint Is Best for Microsoft Environments

Microsoft Defender for Endpoint is the strongest default recommendation for organizations that already use Microsoft 365, Entra ID, Intune or Windows-heavy infrastructure.

The platform supports Windows, macOS, Linux, Android and iOS. Its capabilities include next-generation antivirus, EDR, attack-surface reduction, vulnerability management, automated investigation and response, device discovery and advanced hunting.

Its main advantage is integration. Microsoft Defender can correlate endpoint alerts with signals from identity, email, cloud applications and other Microsoft security products. That can reduce the number of security consoles a team has to manage.

Choose Microsoft Defender for Endpoint if:

  • Your company already licenses Microsoft 365 E5 or another Microsoft security bundle.
  • Windows and Intune are central to device management.
  • You want endpoint, identity, email and cloud security in one portal.
  • You need vulnerability management and automated response alongside antivirus.

Defender for Business vs. Defender for Endpoint

Microsoft Defender for Business is designed for organizations with up to 300 users and is included in Microsoft 365 Business Premium. Defender for Endpoint Plan 2 is aimed at larger organizations and more advanced security operations.

The licensing distinction matters. A smaller business may not need the features or administration overhead of the full enterprise product, while a larger organization may outgrow the capabilities included with a business plan.

2. CrowdStrike Falcon Is Best for Dedicated Enterprise EDR

CrowdStrike Falcon is a strong choice for organizations that want a dedicated endpoint detection and response platform rather than security capabilities bundled into a broader productivity suite.

The Falcon platform combines endpoint protection and EDR through a cloud-based architecture. CrowdStrike positions Falcon for ransomware, supply-chain and AI-driven attacks, with capabilities covering prevention, detection, investigation and response.

CrowdStrike is most suitable for organizations with:

  • A security operations center or experienced incident-response team.
  • A requirement for detailed endpoint telemetry and threat hunting.
  • Large or geographically distributed endpoint fleets.
  • A willingness to standardize on a dedicated security platform.

CrowdStrike reports 100% detection, 100% protection and zero false positives in its interpretation of the 2025 MITRE ATT&CK Enterprise Evaluation. Treat vendor-reported results as one input, not as a universal product ranking. MITRE evaluations test defined attack scenarios and capabilities, not every part of day-to-day operational value.

3. SentinelOne Singularity Endpoint Is Best for Automated Response

SentinelOne is a strong option when the main priority is reducing manual intervention during an attack.

Singularity Endpoint uses behavioral detection, automated containment, remediation and rollback. SentinelOne states that the platform can operate across online, offline, SaaS, on-premises, hybrid and air-gapped environments. Its Storyline capability connects related process, file, network and identity events into an attack narrative. The platform also advertises up to 365 days of EDR context retention.

SentinelOne suits organizations where:

  • A small security team needs automated containment.
  • Ransomware rollback is a high priority.
  • Endpoints may operate offline or in distributed environments.
  • Analysts want related events presented as an attack narrative.

Plan selection is the main buying consideration. Endpoint protection, EDR, identity protection, cloud security, XDR and MDR may be packaged separately. Compare the exact capabilities included in each proposed subscription.

4. Sophos Endpoint Is a Strong Choice for SMBs and MSPs

Sophos Endpoint is particularly suitable for small and midsize businesses that need prevention without building a large security operations team.

Sophos combines deep-learning malware prevention, exploit mitigation, ransomware protection, web protection, application control and coordinated response through the Sophos ecosystem. Sophos states that its endpoint agent supports Windows, macOS and Linux and is designed to provide default-on protection with limited tuning.

Sophos is a practical choice for:

  • Businesses with limited internal security expertise.
  • Managed service providers managing multiple customers.
  • Organizations already using Sophos Firewall, Sophos Email or Sophos MDR.
  • Companies prioritizing ransomware prevention and simpler administration.

Compare Sophos Intercept X and related XDR products carefully. Endpoint protection, XDR, server security and managed detection services may be separate licensing components.

5. Bitdefender GravityZone Is Best for Modular Coverage

Bitdefender GravityZone suits organizations that want to assemble endpoint security from a modular platform.

GravityZone includes separate offerings for business security, EDR, XDR, server security, cloud security and MDR. Bitdefender describes GravityZone Business Security Enterprise as combining endpoint prevention, detection and response. Defense XDR extends visibility across identity, network and productivity applications.

GravityZone is worth shortlisting when you need:

  • Windows, macOS, Linux, Android or iOS coverage.
  • Cloud-managed or on-premises management.
  • EPP, EDR, XDR and MDR options from one vendor.
  • Control over which modules are deployed.

GravityZone is a better fit for buyers who want configuration options than for those seeking the simplest possible license structure. Review server protection, EDR, XDR, vulnerability management and MDR as separate line items before comparing total cost.

6. Palo Alto Cortex XDR Is Best for Integrated SOC Operations

Palo Alto Cortex XDR is a strong choice when an organization already uses Palo Alto Networks firewalls, cloud security or security operations products.

Cortex XDR correlates telemetry from endpoints, networks, cloud environments, identity systems and email. Its endpoint capabilities include machine-learning malware prevention, exploit prevention, ransomware protection, device control, host firewall, disk encryption and vulnerability assessment.

Choose Cortex XDR when:

  • Your SOC already operates Palo Alto Networks technology.
  • You want endpoint data correlated with network and cloud activity.
  • Your security team needs prevention and XDR rather than standalone antivirus.
  • Device control, firewall and encryption are part of the endpoint requirement.

Cortex XDR may be more than a small business needs if the requirement is limited to endpoint antivirus and basic EDR. Its value increases when the organization already uses the wider Palo Alto security platform.

7. ESET PROTECT Is Best for Lightweight and Hybrid Deployments

ESET PROTECT is a useful alternative for organizations that value a lightweight endpoint agent, broad operating-system support and deployment flexibility.

ESET supports Windows, macOS, Linux, Android and iOS-related management scenarios. ESET PROTECT can be managed through a cloud console or on-premises deployment. It can also add EDR, vulnerability and patch management, mobile security, encryption, cloud workload protection and MDR.

ESET is particularly suitable when:

  • Endpoint performance is a major concern.
  • The business needs cloud and on-premises management options.
  • The environment includes several operating systems.
  • The organization wants to add advanced capabilities gradually.

How to Choose an Endpoint Security Tool

The most important buying criteria are:

  1. Prevention: Malware protection, exploit blocking, ransomware controls, web protection and application control.
  2. EDR: Process visibility, investigation timelines, threat hunting, forensic data and incident scoping.
  3. Response: Device isolation, file quarantine, process termination, rollback and automated remediation.
  4. Vulnerability management: Asset inventory, software inventory, risk prioritization and remediation tracking.
  5. Operating-system coverage: Windows, macOS, Linux, servers, mobile devices and virtual environments.
  6. Management: Cloud console, role-based access, policy control, deployment and reporting.
  7. Integration: Microsoft 365, identity providers, SIEM, SOAR, firewalls, email security and cloud platforms.
  8. Managed services: MDR may matter more than another detection feature if the internal team cannot monitor alerts continuously.
  9. Licensing: Compare endpoint, server, EDR, XDR, vulnerability management, data retention, support and MDR costs separately.

Test the Shortlist Before Buying

Independent testing should support, not replace, a pilot. AV-TEST evaluated 18 business endpoint products in its September and October 2025 Windows 11 test. AV-Comparatives also continued its business security testing across protection, malware detection and performance. MITRE ATT&CK Enterprise Evaluations provide another way to examine how vendors detect adversary behaviours, but they are not an overall product ranking.

During a pilot, test the products against your own device mix, management process and incident-response workflow. Check how quickly the team can investigate an alert, isolate a device, identify affected assets and restore normal operations. Licensing should be tested at the same time, since EDR, server protection, XDR, data retention, vulnerability management and MDR may sit in separate tiers.

Final Recommendation

Microsoft Defender for Endpoint is the best starting point for most organizations already invested in Microsoft 365, Windows and Intune. CrowdStrike Falcon is the stronger dedicated EDR choice for mature enterprise security teams. SentinelOne is better suited to buyers that place automated containment and ransomware rollback first.

Sophos, Bitdefender, Cortex XDR and ESET each make more sense in specific environments. The right shortlist depends on the security ecosystem already in place and the team responsible for investigating alerts.

Start with two questions: Which security ecosystem do you already operate, and who will investigate and respond to alerts? Those answers usually narrow the shortlist more effectively than antivirus detection scores alone.
