Cybersecurity Risks Facing Nashua SMBs
Small and mid-sized businesses in Nashua face the same threats as large enterprises, but often with fewer layers of defense.
- Phishing & business email compromise: Targeted emails trick employees into sharing credentials or approving fraudulent payments.
- Ransomware: Attackers encrypt critical data and demand payment. SMBs are increasingly targeted because they are less likely to have robust backups.
- Misconfigured Microsoft 365 tenants: Weak MFA, overly permissive admin accounts, and exposed SharePoint sites are common, exploitable gaps.
- Unpatched systems & exposed services: Outdated software and unnecessary open ports provide easy entry points for attackers.
- Social engineering & AI-powered scams: Attackers use deepfakes, impersonation, and AI-generated email to bypass traditional security awareness.
