Why Professional Services Depend on Strong IT

Professional services operate in some of the most demanding environments. Their risk profile, confidentiality expectations, and reliance on regulatory compliance require modern, secure, and well‑structured IT.

1. Extreme Data Sensitivity

Legal, accounting, and consulting firms manage:

Many firms lack the infrastructure and processes to meet these requirements.

Without standardized controls, firms face security and operational risks.

Threat actors target professional firms due to:
