Small businesses are the new bullseye for ransomware crews. In 2026, industry reports show more than 60% of successful ransomware attacks target organizations with fewer than 250 employees, precisely because these companies often lack dedicated security teams but still hold valuable customer data. Endpoint Detection and Response (EDR) is no longer an enterprise luxury; it has become table stakes. The question is which EDR product actually makes sense for a 10 to 250 person company without breaking the budget or requiring a full-time analyst.
This guide compares the five EDR platforms that dominate the small business market in 2026: CrowdStrike Falcon Go, SentinelOne Singularity Control, Microsoft Defender for Business, Sophos Intercept X Advanced, and Bitdefender GravityZone Business Security Premium.
What EDR Actually Does
Traditional antivirus matches files against a signature database. EDR watches behavior: process trees, registry changes, network connections, memory access patterns. When something looks suspicious, it can automatically isolate the endpoint, roll back changes, and alert an analyst. Most modern EDR products also include threat hunting dashboards and integration with SIEM tools.
For a small business, the key features are:
- Managed detection (someone else watches alerts at 3 AM)
- Automatic rollback of ransomware damage
- Low false-positive rate
- Simple deployment without a dedicated server
- Transparent, per-seat pricing
CrowdStrike Falcon Go
Falcon Go is CrowdStrike’s SMB-focused SKU, stripped down from the enterprise Falcon platform but running the same cloud-native agent. It covers up to 100 endpoints and is sold through a self-service checkout.
Strengths: industry-leading detection on MITRE ATT&CK evaluations, extremely lightweight agent (around 40 MB RAM), no on-premise infrastructure. The Falcon console is clean, and the built-in threat graph makes incident investigation intuitive even for non-specialists.
Weaknesses: Falcon Go lacks some features of higher tiers (no identity protection, limited threat intel). Pricing starts around $59.99 per device per year, which is higher than most competitors on this list. Managed threat hunting (Falcon Complete) is a separate, expensive add-on.
SentinelOne Singularity Control
SentinelOne’s AI-driven approach pioneered autonomous response. The agent makes detection and remediation decisions locally, which means it can stop and roll back ransomware even when a laptop is offline.
Strengths: one-click rollback is genuinely magical the first time you see it work on a ransomware sample. Strong Mac and Linux support. Storyline technology auto-correlates events into readable attack narratives.
Weaknesses: the console has more depth than most SMBs need, which can feel overwhelming. Pricing is quote-based through resellers, typically $45 to $70 per endpoint per year.
Microsoft Defender for Business
If your company already pays for Microsoft 365 Business Premium, Defender for Business is included. Even as a standalone purchase at $3 per user per month, it is the cheapest serious EDR on the market.
Strengths: tight integration with Windows, Intune, and Microsoft 365. No separate agent to install on Windows endpoints; it builds on the Defender already in the OS. Attack surface reduction rules are powerful when tuned.
Weaknesses: Mac and Linux support exists but lags behind Windows. The interface spans several Microsoft portals, which can be confusing. Automated investigation is good but not as polished as CrowdStrike or SentinelOne.
Sophos Intercept X Advanced with XDR
Sophos combines traditional antivirus, EDR, and XDR in a single agent and management console (Sophos Central). It is popular among managed service providers for SMB deployments.
Strengths: CryptoGuard anti-ransomware is excellent and has stopped real-world campaigns consistently. The Sophos Central console is arguably the friendliest for non-experts. Synchronized Security ties endpoint, firewall, and email protection together.
Weaknesses: the agent is heavier than competitors (200 MB+ RAM is common). Some features require MSP engagement rather than direct purchase.
Bitdefender GravityZone Business Security Premium
Bitdefender’s EDR offering builds on its top-rated antivirus engine. It is a favorite among budget-conscious SMBs that still want strong detection.
Strengths: consistently top scores in AV-Test and AV-Comparatives. Hypervisor Introspection is unique for virtualized environments. Per-endpoint pricing around $30 to $45 per year is among the lowest.
Weaknesses: the console is functional but dated. Managed detection services are newer and less mature than CrowdStrike’s.

|---|---|---|---|---|---|
| Starting price/endpoint/year | $60 | ~$55 | $36 | ~$50 | ~$38 |
| Ransomware rollback | Add-on | Yes | Partial | Yes | Limited |
| Managed detection | Add-on | Add-on | Add-on | Add-on | Add-on |
| Mac support | Excellent | Excellent | Good | Excellent | Excellent |
| Linux support | Good | Excellent | Basic | Good | Good |
| Ease of use (1-5) | 4 | 3 | 3 | 5 | 3 |
| Enterprise-grade detection | Yes | Yes | Yes | Yes | Yes |
Deployment Considerations
For a company under 50 endpoints with no dedicated IT, Sophos or Bitdefender through a managed service provider is usually the easiest path. For Microsoft 365 shops, Defender for Business is the obvious starting point and often sufficient. If you want best-in-class detection and have someone who can watch alerts, CrowdStrike Falcon Go is hard to beat. For Mac and Linux heavy environments, SentinelOne shines.
Total Cost of Ownership
Licensing is only part of the story. A good MDR (Managed Detection and Response) wrap typically doubles the per-endpoint cost but eliminates the need for in-house expertise. Factor in integration time, training, and the cost of a single incident (average SMB ransomware recovery cost is around $85,000 in 2026), and the premium for a top-tier product usually pays for itself on the first avoided incident.
Common Mistakes to Avoid
- Buying EDR but leaving it in audit-only mode indefinitely
- Excluding too many folders from scanning to fix a performance complaint
- Ignoring low-severity alerts that indicate recon behavior
- Not enabling multi-factor authentication on the EDR console itself
- Failing to test endpoint isolation before a real incident
FAQ
Do I need EDR if I have a good antivirus? Modern antivirus is largely signature-based. EDR catches the behavioral tactics attackers use to bypass AV, like living-off-the-land techniques with PowerShell or WMI.
Can I run EDR alongside my existing antivirus? Most EDR products include or replace AV. Running two real-time scanners simultaneously causes performance and stability issues.
Is cloud EDR safe for privacy? Reputable vendors process telemetry metadata, not file contents. Review the data processing addendum before purchase.
How long does deployment take? For under 100 endpoints using cloud-managed EDR, full deployment can take a single afternoon once agents are packaged.
What is XDR and do I need it? XDR extends EDR across email, cloud, and identity. For most SMBs, start with EDR and add XDR components as budget allows.
Does EDR slow down computers? Modern agents are lightweight. Expect 1 to 3% CPU overhead. SentinelOne and CrowdStrike are particularly efficient.
Final Recommendation
For most small businesses in 2026, the right answer is either Microsoft Defender for Business (if you are a Microsoft 365 shop) or Sophos Intercept X Advanced through an MSP (if you want guided setup). Companies with higher risk profiles or compliance requirements should step up to CrowdStrike Falcon Go or SentinelOne. Whichever you pick, deploy it, tune it, and actually read the alerts. The best EDR in the world cannot save a business that ignores its warnings.
