Why Every CPA and Law Firm Needs a Written Information Security Plan (WISP)

If your firm handles sensitive personal or financial data, you need a Written Information Security Plan (WISP)—not just for compliance, but to protect your clients, your reputation, and your future.

For CPA Firms, this is a legal requirement under the FTC Safeguards Rule, which mandates that firms develop and implement a comprehensive WISP to safeguard client information.

For Law Firms, while there is no federal WISP mandate at this time, client confidentiality and data security are increasingly under the microscope. With rising cyberattacks on legal practices, a WISP helps demonstrate ethical due diligence and reduce the risk of legal exposure if a breach occurs.

What’s at Risk Without a WISP?

• ⚠️ Regulatory Non-Compliance (CPA Firms):

  If you prepare taxes or manage financial data and haven’t implemented a WISP, you’re out of compliance with the FTC Safeguards Rule. This can result in fines, audits, and enforcement actions—especially if a data incident occurs.

• ⚠️ Legal Liability (CPA and Law Firms):

  A data breach is no longer an “if,” but a “when.” Without a WISP in place, your firm could be accused of negligence, opening the door to lawsuits, regulatory penalties, or disciplinary action.

• ⚠️ Client Trust and Reputation:

  Cybersecurity is a client expectation. A data breach—or even an admitted lack of planning—can cause significant reputational damage, especially for firms built on trust and confidentiality.

So, What Is a WISP?

A WISP is your firm’s written roadmap to protecting client data. It outlines:

• How your firm stores, accesses, and protects sensitive data

• Who is responsible for data security

• Your incident response plan in the event of a cyberattack

• Ongoing employee training requirements

• Vendor and software management protocols

It’s not just paperwork—it’s proof that your firm is actively managing cyber risk.
