Business email compromise is when a criminal gets into, or imitates, a mailbox to redirect payments. For Nashville firms that send invoices, pay vendors or move client funds by wire, one convincing email can cost more than a year of IT.
Who gets targeted in Nashville
Healthcare companies and practices across Nashville and Franklin need HIPAA training and secure systems. Accounting and law firms downtown handle sensitive client data. Construction firms keeping up with Middle Tennessee growth need plans and email on job sites.
Firms like these send and receive payments by email every week, which is exactly what attackers look for.
How mailbox takeovers start
A stolen password, a fake login page or a look-alike domain lets an attacker read mail, set hidden forwarding rules and send payment requests that look real.
Locking down Microsoft 365
Multi-factor authentication, conditional access, safe sign-in settings and mail flow rules close the common ways in. Filtering catches look-alike domains and malicious links before they reach the inbox.
Tennessee data rules to know
Tennessee’s breach notification law, T.C.A. 47-18-2107, requires notice to affected residents within 45 days of discovering a breach. The Tennessee Information Protection Act adds consumer privacy rights for larger businesses.
A hacked mailbox often holds customer records, so an email takeover can become a reportable breach.
Watching for takeover signs
We monitor for suspicious sign-ins, new forwarding rules, account changes and unusual sending patterns. During office hours an engineer acts on alerts by locking the account, resetting credentials and checking what was sent.
