Texas SB 2610 · In effect since September 1, 2025
The Texas cybersecurity safe harbor, explained for small firms
If your business has fewer than 250 employees and holds sensitive client data, SB 2610 can shield you from punitive damages after a breach — but only if you can show a real cybersecurity program was in place. This guide explains what that takes, in plain English.
Written for Texas tax, accounting, and CPA practices that run on Microsoft 365.

What SB 2610 does
Senate Bill 2610 added Chapter 542 to the Texas Business & Commerce Code. It gives qualifying small businesses a defense in one specific situation.
- It blocks exemplary (punitive) damages in a lawsuit over a data breach — if your cybersecurity program met the statute’s requirements when the breach happened.
- It does not erase liability. Ordinary damages and Attorney General enforcement are unaffected.
- It does not create a new right to sue, for or against you.
- The practical takeaway: have a documented program — usually a Written Information Security Program (WISP) — scaled to your size and tied to a recognized framework.
Who it covers
A business in Texas with fewer than 250 employees that owns or licenses computerized data containing sensitive personal information. Every covered size needs a cybersecurity program aligned to a recognized framework. Headcount only changes how much is expected.
The statute names password policies and employee cybersecurity training as the floor — not the whole program. A lightweight, framework-aligned program is still required.
Includes the CIS Critical Security Controls Implementation Group 1 (IG1), on top of the requirements that apply to every covered business.
Conform to a listed framework such as NIST CSF, CIS Controls, ISO 27000, SCF, or SOC 2.
