What is different about IT for finance and accounting

Financial firms carry client money and client identity, which makes them a standing target and puts them under examination. The provider is expected to produce evidence, not assurances: change logs, access reviews, and a written incident response plan an examiner can read.

Compliance that actually bites

Depending on the firm, the SEC and FINRA cybersecurity expectations, the Gramm-Leach-Bliley Safeguards Rule, PCI-DSS where cards are handled, and SOC 2 Type II. Reg S-P notification duties make a quiet breach an expensive one.

Questions worth asking a provider

  • What evidence can you hand an examiner without us preparing it first?
  • How do you handle privileged access, and who at your firm can reach our data?
  • What is your notification process and timeline if you detect a breach in our environment?
