Setting Up Input Boundaries for Customer Data

When Sarah, owner of a growing marketing consultancy, started using AI tools to analyze customer feedback, she thought she was being smart about efficiency.

Small business owners often assume that robust AI security requires expensive enterprise-grade solutions, dedicated IT staff, and complex infrastructure investments. This misconception leads many to either avoid AI altogether or implement it with dangerously minimal protections. The reality is quite different: effective AI security for small businesses relies more on smart processes and careful tool selection than on costly software packages.
