Cyberattacks cost small businesses an average of $108,000 per incident in 2025, and 60% of small companies that suffer a major breach close within six months. The threat landscape has shifted dramatically. Ransomware, phishing, and supply chain attacks now target small businesses specifically because attackers know these organizations lack enterprise security budgets. The good news is that modern endpoint protection platforms use AI and behavioral analysis to stop threats automatically, without requiring a full-time security analyst. We tested five cybersecurity tools on detection accuracy, ease of deployment, management overhead, and total cost for teams of 10 to 200 employees.

1. CrowdStrike
CrowdStrike Best Overall Protection
CrowdStrike Falcon is the endpoint protection platform that Fortune 500 companies trust, and the Falcon Go tier makes it accessible to small businesses. The lightweight agent runs on Windows, macOS, and Linux without noticeable performance impact. CrowdStrike uses cloud-based AI to analyze behavior patterns rather than relying on signature databases, which means it catches zero-day threats that traditional antivirus misses entirely. The Falcon console provides real-time visibility into every endpoint, with automated response actions that contain threats in seconds. For businesses that want enterprise-grade protection without enterprise complexity, CrowdStrike sets the standard.
- Key strength: AI-powered behavioral detection that stops zero-day threats and fileless attacks in real time
- Performance: Single lightweight agent uses minimal CPU and memory - users do not notice it running
- Management: Cloud-native console with no on-premises infrastructure required
- Pricing: Falcon Go at $59.99/device/year; Falcon Pro at $99.99/device/year; Falcon Enterprise custom pricing
2. SentinelOne
SentinelOne Best Automated Response
SentinelOne takes automated threat response further than any competitor. When the agent detects malicious activity, it can kill the process, quarantine the file, roll back changes to the system, and remediate the affected endpoint - all without human intervention. This autonomous response capability is critical for small businesses that do not have a security operations center monitoring alerts around the clock. The Singularity platform also includes network visibility and identity threat detection, giving you protection beyond just endpoints. SentinelOne consistently scores at the top of independent testing from MITRE ATT&CK evaluations.
- Key strength: Autonomous threat response with one-click rollback - contains attacks without waiting for human review
- Coverage: Protects endpoints, cloud workloads, and identities from a single platform
- Rollback: Ransomware recovery through automated system rollback to pre-infection state
- Pricing: Singularity Core at $69.99/device/year; Singularity Control at $79.99/device/year; Singularity Complete at $159.99/device/year
3. Bitdefender
Bitdefender Best Value
Bitdefender GravityZone delivers detection rates that rival CrowdStrike and SentinelOne at roughly half the per-device cost. The platform includes endpoint protection, risk analytics, patch management, and full disk encryption in a single license. Bitdefender's hyperdetect module uses machine learning trained on billions of samples to catch sophisticated threats, while the sandbox analyzer detonates suspicious files in an isolated environment before they reach endpoints. For small businesses that need serious protection on a realistic budget, Bitdefender provides the best ratio of security capability to dollar spent.
- Key strength: Enterprise-grade detection at the lowest per-device cost of any premium endpoint platform
- Included: Patch management, full disk encryption, web filtering, and device control in every business license
- Sandbox: Suspicious files are analyzed in an isolated cloud environment before reaching endpoints
- Pricing: GravityZone Business Security at $38.99/device/year; GravityZone Business Security Premium at $57.49/device/year
4. Malwarebytes
Malwarebytes Easiest to Manage
Malwarebytes built its reputation on malware removal, and the business endpoint platform carries that effectiveness into real-time protection. The Nebula cloud console is the simplest management interface in this comparison - you can deploy agents, configure policies, and review threats without security expertise. Malwarebytes ThreatDown bundles endpoint protection with vulnerability assessment, patch management, and DNS filtering into packages designed specifically for small IT teams. If you need solid protection that a non-technical office manager can oversee, Malwarebytes lowers the management burden more than any competitor.
- Key strength: Simplest management console - deploy and manage protection without specialized security knowledge
- ThreatDown: Bundled vulnerability assessment, application patching, and DNS filtering in business packages
- Remediation: Proprietary Linking Engine removes all traces of malware including registry entries and system changes
- Pricing: ThreatDown Core at $69/endpoint/year; ThreatDown Advanced at $79/endpoint/year; ThreatDown Elite at $99/endpoint/year
5. Norton Small Business
Norton Small Business Best Known Brand
Norton has protected computers for over three decades, and the Small Business product packages that experience into a solution built for teams of 5 to 20 devices. Norton combines antivirus, VPN, password manager, cloud backup, and dark web monitoring in a single subscription. The detection engine uses SONAR behavioral analysis alongside traditional signatures to catch both known and unknown threats. While Norton lacks the advanced EDR capabilities of CrowdStrike or SentinelOne, it covers the security basics thoroughly. For very small businesses that want comprehensive basic protection from a brand they recognize, Norton delivers reliable coverage without complexity.
- Key strength: All-in-one security bundle - antivirus, VPN, password manager, backup, and dark web monitoring included
- Setup: Consumer-grade ease of installation - download, install, and protection is active within minutes
- Dark web monitoring: Scans for leaked business email credentials and personal information on dark web forums
- Pricing: Norton Small Business at $49.99/device/year for 6+ devices; volume discounts available for 11+ devices

| Tool | Per Device/Year | Detection Method | Auto Response | Management | Best For |
|---|---|---|---|---|---|
| CrowdStrike | From $59.99 | AI Behavioral | Yes | Cloud Console | Overall Protection |
| SentinelOne | From $69.99 | AI Behavioral | Best (Rollback) | Cloud Console | Automated Response |
| Bitdefender | From $38.99 | ML + Sandbox | Yes | Cloud Console | Budget Value |
| Malwarebytes | From $69 | Behavioral + Signature | Partial | Simplest Console | Easy Management |
| Norton | From $49.99 | SONAR + Signature | Basic | Simple Dashboard | Basic All-in-One |
How to Choose
Businesses handling sensitive data - financial records, healthcare information, customer payment data - should choose CrowdStrike or SentinelOne. The AI-powered behavioral detection catches sophisticated attacks that signature-based tools miss, and the automated response contains threats before they spread.
Budget-conscious businesses that still need real protection should go with Bitdefender. At roughly $39 per device per year, it delivers detection rates that compete with tools costing twice as much, and includes patch management and encryption that others charge extra for.
Businesses without IT staff should consider Malwarebytes. The Nebula console is genuinely simple to operate, and the ThreatDown bundles combine multiple security functions into a single manageable package.
Very small teams of under 10 people who want basic all-around protection should look at Norton Small Business. The included VPN, password manager, and cloud backup cover common security gaps that endpoint protection alone does not address.
Final Verdict
CrowdStrike Falcon Go provides the strongest protection available for small businesses. The per-device cost is higher than Bitdefender, but the detection accuracy and cloud-native management justify the premium for any business where a breach would be catastrophic. SentinelOne is the right choice when autonomous response matters most - its rollback capability is genuinely unique. Bitdefender GravityZone offers the best value, packing enterprise features into the most affordable package. Malwarebytes wins on simplicity for teams that lack security expertise. And Norton covers the basics well for very small offices that want a familiar, trusted brand.
