Top 5 Security Exposures Found in Small Business Networks
The Most Common Exposures
Based on ThreatMate's analysis of thousands of small business networks, here are the top 5 security exposures we consistently find:
1. Exposed Remote Access (RDP, VNC, SSH)
Remote access services exposed directly to the internet are constantly targeted by automated attacks. We find exposed RDP in over 30% of small business scans.
Fix: Use VPN or zero-trust access. Never expose RDP directly.
2. Missing or Misconfigured MFA
Even when MFA is "enabled," we often find exceptions — admin accounts, service accounts, or legacy protocols that bypass MFA.
Fix: Audit MFA coverage. Disable legacy authentication.
3. Outdated and Unpatched Systems
End-of-life operating systems and unpatched software with known vulnerabilities remain shockingly common.
Fix: Implement patch management. Plan upgrades for EOL systems.
4. Leaked Credentials on the Dark Web
Employee credentials from third-party breaches are actively sold and used in credential stuffing attacks.
Fix: Monitor for credential exposure. Enforce password resets for compromised accounts.
5. Email Authentication Failures (SPF/DKIM/DMARC)
Missing or misconfigured email authentication allows attackers to impersonate the organization in phishing attacks.
Fix: Implement DMARC with enforcement. Monitor for spoofing attempts.
