EDR Solutions Compared: What Small Businesses and MSSPs Should Know Before Buying

• BizVuln Staff

Not all EDR solutions are built for SMB and MSSP workflows. This direct comparison of SentinelOne, CrowdStrike Falcon Go, Microsoft Defender for Business, and Huntress covers real-world pricing, deployment friction, alert fidelity, and the critical gaps every buyer must address.

The endpoint detection and response (EDR) market is flooded with options, but most reviews target enterprise buyers with dedicated SOCs. If you run an MSSP or manage security for a small to midsize business (SMB), your requirements are fundamentally different: you need affordable pricing, fast deployment, manageable alert volumes, and—most importantly—multi-tenant administration.

This article compares four leading EDR solutions that actually fit SMB and MSSP budgets and workflows: SentinelOne, CrowdStrike Falcon Go, Microsoft Defender for Business, and Huntress. We’ll break down pricing, ease of deployment, alert quality, and—critically—what every EDR solution misses, so you can make an informed purchase and avoid expensive blind spots.

Why EDR Solutions Matter for SMBs and MSSPs

Small businesses are prime ransomware targets because they often lack dedicated security staff. MSSPs fill this gap by offering managed detection and response, but the tools they choose must be cost-effective and easy to operate across dozens or hundreds of tenants.

An EDR solution is your first line of defense against file-based malware, script attacks, and ransomware. However, “first line” does not mean “only line.” Even the best EDR agents rely on known signatures, behavioral heuristics, and threat intelligence feeds. They cannot detect unmanaged assets, exposed cloud services, or third-party risk. That’s where an external attack surface management (ASM) platform like BizVuln steps in—but we’ll get to that later.

First, let’s look at the four contenders that dominate the SMB and MSSP space.

The Big Four: Head-to-Head Comparison

SentinelOne

SentinelOne’s Singularity platform offers autonomous AI-driven detection and response. Its strength is real-time prevention—it can roll back malicious actions without human intervention.

CrowdStrike Falcon Go

CrowdStrike’s Falcon Go is the lightweight, SMB-focused version of its flagship Falcon platform. It strips out many enterprise modules but keeps strong AI-based detection.

Microsoft Defender for Business

Part of the Microsoft 365 Business Premium ecosystem, Defender for Business provides integrated EDR without an extra agent if you already own Microsoft 365.

Huntress

Huntress started as a managed detection service for small MSPs and has evolved into a full EDR-plus-MDR solution. Their model is a flat per-agent fee that includes human analysis.

Pricing and Deployment: Real-World Costs and Effort

Pricing for EDR solutions is rarely as straightforward as the per-endpoint sticker. Here’s what often gets buried in the fine print:

Deployment effort varies widely:

If you manage more than ten clients, multi-tenant support becomes a dealbreaker. Huntress and SentinelOne offer the best out-of-the-box multi-tenant experiences. CrowdStrike Falcon Go forces you into per-account management hell.

Alert Quality and False Positive Management

Alert fatigue is the number one reason MSSPs dump a tool. A high-fidelity EDR should generate fewer than 5% false positives in a typical SMB environment.

For MSSPs that don’t run a 24/7 SOC, Huntress’s approach is the clear winner. For in-house IT teams that want full control, SentinelOne’s automation reduces the monitoring burden.

What EDR Solutions Miss: Critical Blind Spots

This is the most underreported aspect of buying EDR solutions. No endpoint agent can see everything. Here’s what every EDR misses:

  1. **Unmanaged assets**: Devices that haven’t installed the EDR agent, including employee personal devices (BYOD), IoT gear, printers, and guest Wi-Fi devices.
  2. **Cloud exposure**: Misconfigured S3 buckets, exposed RDP ports, open databases, and public-facing APIs. EDR agents live on endpoints; they cannot scan your cloud tenant.
  3. **Phishing websites and brand impersonation**: An EDR blocks a malicious download *after* the user clicks. It cannot prevent the user from visiting a lookalike login page.
  4. **Third-party vulnerabilities**: If a vendor’s platform gets compromised, your EDR won’t know until the attacker pivots to your endpoints.
  5. **Internet-facing services**: Firewalls, VPNs, web servers—these have no EDR agent. They are invisible to endpoint detection.

For an MSSP or SMB, these blind spots are where real breaches start. Attackers frequently target external services first, then use legitimate credentials to move laterally. An EDR catches the post-exploitation phase—too late.

The fix: Pair your EDR with external attack surface monitoring (ASM). Tools like BizVuln continuously scan your public-facing infrastructure, find unmanaged assets, and alert you to exposures before an attacker exploits them.

MSSP Multi-Tenant Management: Which Tool Scales?

Multi-tenant management is not a nice-to-have for MSSPs; it’s the core operational requirement. Here’s how the four solutions compare:

| Feature | SentinelOne | CrowdStrike Falcon Go | Microsoft Defender | Huntress |

|---------|-------------|-----------------------|--------------------|----------|

| Dedicated multi-tenant console | Yes (Sites) | No (separate accounts) | Yes (Lighthouse) | Yes (Partner Cloud) |

| Cross-tenant alerting | Yes | Manual | Yes | Yes (aggregated) |

| Client isolation | Yes | Yes (per console) | Yes (via Intune) | Yes (one click) |

| API for automation | Full REST API | Limited | Graph API (complex) | Full REST API |

| Deployment scripting | Yes (Silent install) | Yes but manual steps | Yes (Intune) | Yes (any RMM) |

Verdict: For an MSSP managing more than 20 clients, choose between Huntress (easiest, SOC inclusive) or SentinelOne (most flexible, automation-friendly). CrowdStrike Falcon Go is a non-starter for multi-tenant. Microsoft Defender works but requires significant Azure expertise to set up Lighthouse correctly.

Actionable Checklist for Evaluating EDR Solutions

Use this step-by-step checklist when comparing EDR solutions for your business or MSSP.

  1. **Define your monitoring scope** – Do you have only Windows endpoints, or also macOS, Linux, servers, and cloud workloads? Some EDRs charge extra for server coverage.
  2. **Calculate total cost** – Include per-endpoint price, minimum seat count, annual increases, and license costs (Microsoft’s user license can be 4× the endpoint price).
  3. **Test multi-tenant management** – If you’re an MSSP, demand a live demo of the partner console. Add five test clients and see how many clicks it takes to deploy an agent and view alerts.
  4. **Assess alert fidelity** – Run a month-long trial with real production traffic. Measure the number of true positives vs. noise. If the sales team says “tuning takes time,” they mean it’s noisy.
  5. **Identify blind spots** – Map your external attack surface (public IPs, domains, cloud services). Ask: “What happens if an attacker finds a vulnerable RDP before the EDR sees a breach?”
  6. **Plan for response** – Does the EDR allow remote isolate, kill process, and rollback? Can you automate these actions via API? Manual response doesn’t scale.
  7. **Check compliance integrations** – If you need reports for HIPAA, PCI, or SOC 2, ensure the EDR can export device compliance and incident timelines.
  8. **Incorporate continuous monitoring** – Layer an ASM tool (e.g., BizVuln) on top to cover unmanaged assets and external exposures. No EDR is a complete solution alone.

Frequently Asked Questions

Which EDR solution is best for a 25-person small business?

For a standalone SMB without an MSSP, Microsoft Defender for Business (if on M365) or CrowdStrike Falcon Go are strong choices. If you want zero management overhead, Huntress gives you a 24/7 SOC for roughly the same price.

Is CrowdStrike Falcon Go really “enterprise-grade”?

Yes, the detection engine is the same as Falcon Enterprise. However, you lose advanced features like threat hunting, real-time response, and multi-tenant support. It’s a stripped-down version, but still effective for basic EDR.

Can EDR replace antivirus?

Modern EDR includes antivirus (NGAV), but many SMBs still run a separate signature-based AV for older malware. Most EDR vendors claim NGAV alone is sufficient. In practice, running both can cause conflicts. Stick with the EDR’s built-in prevention module.

Why do MSSPs prefer Huntress over SentinelOne?

Huntress was built specifically for MSP/MSSP workflows: single pane of glass, flat pricing, and SOC triage removed alert noise. SentinelOne is more feature-rich but requires more manual configuration per tenant. If you don’t have a 24/7 SOC, Huntress drastically simplifies operations.

What does BizVuln do that EDR cannot?

BizVuln performs passive OSINT scanning of your public-facing infrastructure—IPs, domains, open ports, and cloud misconfigurations—without requiring any agents. It discovers assets you didn’t know you had and alerts you to exposures that an EDR agent would never see. It’s the missing visibility layer for any EDR deployment.
