Industry guidance

Cybersecurity for Small Professional Services Firms

Quick answer

Professional services firms usually depend on email, shared documents, client data, and a small number of privileged accounts. A focused baseline reduces the most common account and data risks.

Who this is for: Accounting, legal, consulting, marketing, and other professional services firms.

What to do

  1. 01Secure email, finance, document, and client-portal accounts with MFA.
  2. 02Use separate administrator accounts and review client-data access.
  3. 03Set clear retention, sharing, vendor, and offboarding practices.
  4. 04Prepare a phishing and business-email-compromise response plan.

What this does not cover

Industry guidance is a practical starting point, not a complete audit, certification, or legal determination. Requirements depend on your systems, contracts, jurisdictions, and data.
