Small and Medium Business Cyberattacks and the AI Security Gap

Microsoft 2026-01-15 data leakage High

Executive Summary

Microsoft's SMB report finds most SMBs think AI increases security needs, yet many are only somewhat effective at basics like MFA, patching, access control, backups and incident response.

What Happened

Microsoft’s SMB Cybersecurity report finds that a large majority of SMBs believe AI increases the need for additional security, yet many are only somewhat effective at basic practices such as MFA, patching, access control, backups, and incident response.[8] The report highlights that AI-driven threats amplify existing weaknesses in identity management and data protection, increasing the likelihood of data leakage and business email compromise for resource-constrained organizations.[8] It calls for SMBs to strengthen core controls and governance as they adopt AI tools, rather than relying on AI alone for security.[8]
