Malwarebytes Teams vs Microsoft Defender: The 2026 Guide for Small Businesses

Small business owners face a critical security question: should you stick with the free Windows Defender, upgrade to Malwarebytes Teams, or invest in Microsoft Defender Business? The answer isn't about which product is "best"—it's about matching your protection level to your team size, technical skills, and existing infrastructure.

This guide examines all three options through a practical lens. We'll show you when the free option is sufficient, when paying $60 per year makes sense, and when enterprise-grade protection justifies $3 per month. You'll see real-world scenarios for solopreneurs, micro-teams, and growing businesses to help you make an informed decision without overpaying or leaving gaps in your security.

Endpoint protection is just one component of business security. For broader security planning, see our comprehensive cybersecurity services or explore our guide on small business IT security best practices.

Understanding Your Three Options

Before comparing paid solutions, it's essential to understand the free baseline that every Windows user already has.

Windows Security (Free): The Built-In Option

Every Windows 10 and 11 computer includes Windows Security (formerly Windows Defender) at no cost. For solopreneurs running a single PC, this built-in protection often provides adequate security.

What Windows Security Does Well:

• Real-time malware protection with cloud-powered detection
• Automatic updates through Windows Update
• Firewall and network protection
• Basic ransomware protection (Controlled Folder Access)
• Zero additional cost

Where the Free Option Falls Short:

The limitations become apparent the moment you hire your first employee or add a second device:

• No Central Dashboard: You cannot see if your employee's antivirus is active, updated, or has detected threats
• Mac/Mobile Gap: It does not protect MacBooks, iPhones, or Android devices
• No Remote Management: You must physically access each computer to check status or adjust settings
• Support: There is no phone number to call if you get hacked—only community forums
• Limited Ransomware Protection: Controlled Folder Access must be manually enabled and offers no file rollback

The Bottom Line on Free Defender:

Windows Security works well for solopreneurs using a single Windows PC with limited budget. However, businesses with multiple employees face visibility challenges—there's no way to monitor whether antivirus is active across devices, and Mac or mobile device protection isn't available. Support is limited to community forums rather than direct assistance.

For teams with multiple devices or mixed platforms, paid solutions like Malwarebytes Teams and Microsoft Defender Business offer centralized management and broader device support.

Final Verdict: Which One Do You Need?

The right security solution depends on your specific situation. Here's how to choose:

Stick with Windows Security (Free) if:

• ✅ You are a one-person company using a single Windows PC
• ✅ You have a $0 budget for security software
• ✅ You're comfortable managing your own security settings
• ✅ You don't need to protect Macs, iPhones, or Android devices
• ✅ You can troubleshoot issues using community forums

Important Note: The free option works for solopreneurs, but adding employees creates visibility challenges. Without centralized management, you'll need to manually verify each device's security status, which becomes time-consuming as your team grows.

Buy Malwarebytes Teams if:

• ✅ You have 2-20 employees using a mix of Windows, Mac, or mobile devices
• ✅ You don't have an IT person on staff
• ✅ You want a single dashboard to see everyone's protection status at a glance
• ✅ You need something that "just works" without complex configuration
• ✅ You want email/chat support when something goes wrong

Why This Works: Malwarebytes Teams gives you a simple link to email your staff. They click it, install the software, and you instantly see a "Green/Red" status for all 20 of your company's devices. No IT degree required.

Upgrade to Microsoft Defender Business if:

• ✅ You already pay for Microsoft 365 Business Premium ($22/user/month)
• ✅ You have IT expertise or a managed service provider
• ✅ You need enterprise-grade EDR with rollback capabilities
• ✅ Your team primarily uses Windows devices in an Office 365 environment
• ✅ You can invest 2-4 weeks in proper setup and configuration

Important Consideration: Microsoft Defender Business provides enterprise-grade security but requires technical expertise for proper setup. While it's included with Microsoft 365 Business Premium subscriptions, successful implementation depends on having staff or partners familiar with Intune and the Defender portal configuration.

Frequently Asked Questions

Is the free Windows Defender really good enough for my business?

For a single-person business using one Windows PC, yes. Windows Security provides solid malware protection at no cost. However, the moment you hire your first employee, you lose the ability to monitor their security status. You cannot see if their antivirus is active, if they've disabled it, or if threats have been detected. You also cannot protect Macs or mobile devices with the free version.

Why should I pay for Malwarebytes when Windows Defender is free?

The key difference is visibility and management. With free Windows Defender, you must physically check each employee's computer to verify their protection status. Malwarebytes Teams gives you a single dashboard showing the security status of all devices in your company. You can see at a glance if someone's protection is disabled or if threats have been detected. For a 5-person team, this saves hours of manual checking each month.

Can I run Malwarebytes alongside Windows Defender?

Yes, Malwarebytes Teams is designed to work alongside Windows Security without conflicts. However, you should not run both Microsoft Defender Business and Malwarebytes Teams simultaneously, as they will conflict with each other.

Which solution provides better protection against ransomware?

Windows Security (Free): Basic protection with Controlled Folder Access (often disabled by default), no rollback. Malwarebytes Teams: Better prevention through behavioral analysis and ransomware remediation, but no rollback. Microsoft Defender Business: Best protection with Automatic Attack Disruption and rollback capabilities to restore encrypted files.

For most small businesses, preventing the attack (Malwarebytes) is more practical than configuring complex rollback systems (Defender Business).

How do these solutions handle Mac and mobile device protection?

Windows Security (Free): No Mac or mobile protection. Malwarebytes Teams: Full protection across Windows, Mac, iOS, and Android with unified management. Microsoft Defender Business: Windows-focused with limited Mac support; requires additional Microsoft Intune licensing for mobile device management.

Which solution requires less ongoing maintenance?

Windows Security (Free): Zero maintenance cost, but you must manually check each device. Malwarebytes Teams: 1-2 hours monthly for basic monitoring. Microsoft Defender Business: 3-5 hours monthly due to complex configuration options.

For businesses without internal IT staff, our IT support services can manage security software maintenance for any of these solutions.

What happens if my business outgrows these solutions?

Both paid vendors offer upgrade paths. Microsoft provides migration to Defender for Endpoint, while Malwarebytes offers ThreatDown Advanced and Elite tiers. If you're using the free Windows Security, you can upgrade to either paid solution at any time.
