Microsoft Security for Small Business

Summary

Microsoft 365 Business Premium includes built-in cybersecurity features that protect your business from phishing, ransomware, and unauthorized access. The guidance follows the Zero Trust model—“never trust, always verify”—meaning every login and every device is checked before access is granted.

What You Need to Know

  • Microsoft 365 Business Premium is the recommended plan for businesses up to 300 employees. It includes Office apps (Word, Excel, etc.) plus business-grade security features—often at a lower cost than buying standalone security tools separately.
  • Zero Trust security principles:
    • Verify explicitly: Every login requires multi-factor authentication (MFA). No more single passwords.
    • Least privilege: Employees get access only to the files and systems they need for their job.
    • Assume breach: If an attacker gets in, the system detects and contains them automatically.
  • Defender for Business: Built-in endpoint protection that watches for suspicious activity on your computers—replaces traditional antivirus with AI-powered threat detection.
  • Security defaults (one-click setup): Microsoft’s pre-configured security settings turn on MFA and block risky legacy connections instantly—no configuration needed.
  • Even lower plans include security: Microsoft 365 Business Standard includes safe links, safe attachments, MFA, and conditional access.

Take Action Today

  1. Turn on Security Defaults: If you use Microsoft 365, enable Security Defaults in the admin center—this activates MFA for all accounts with one click.
  2. Review your plan: If you’re on Business Standard, you already have many security features—make sure they’re turned on.
  3. Download the cybersecurity playbook: Microsoft’s free SMB Cybersecurity Playbook walks through setup step by step.
