Real-World Playbook: How Texas SMBs Can Respond to a Zero-Day Cyberattack Under SB 2610

Texas SMBs are facing an unprecedented wave of cyberattacks. Zero-day exploits are driving up risk for every company, regardless of size. As attacks become faster and more sophisticated, small businesses must not only respond quickly but also align their actions with new legal protections like Texas SB 2610. 

What Is a Zero-Day Exploit? 

A zero-day exploit is a cyberattack that takes advantage of a previously unknown software vulnerability. This means there is no time between the discovery of the flaw and active exploitation. These attacks can slip through traditional defenses, making them a favorite weapon for both cybercriminals and state-backed actors. 

Why Legal Readiness Is Just as Important as Technical Defense 

Under SB 2610, Texas businesses with fewer than 250 employees can access a legal safe harbor from punitive damages if they can show they have implemented industry-recognized cybersecurity practices. If a zero-day attack occurs, a prepared business not only limits operational damage but can also avoid costly legal fallout. 

Your Zero-Day Incident Response Playbook 

1. Detect and Contain Immediately
   Use real-time monitoring tools to spot unusual activity early. Isolate affected systems and deploy endpoint security to block malware spread. Bring in expertise, such as your internal IT team or a responsive partner like Fluid IT, to lead the incident response effort.
2. Document Everything and Preserve Evidence
   Careful recordkeeping is required for both SB 2610 compliance and forensic investigation. Track how the breach was discovered, log steps taken, and keep records of all communications.
3. Notify and Communicate
   Notify affected parties quickly. This includes your insurer, customers, and possibly regulators. Using template communications and compliance frameworks such as CIS, NIST CSF, or ISO 27001 can simplify this process and demonstrate good faith to authorities.
4. Analyze and Remediate
   Once the immediate threat is contained, work with your IT partner to analyze the attack vectors, patch software, and improve defenses to prevent recurrence. Use what you learn as evidence of your commitment to ongoing compliance improvement.
5. Review Incident for Legal Protection
   Consult your MSP or legal counsel to ensure your cybersecurity program aligns with SB 2610 expectations. Conduct an after-action review and adjust company policies as needed to maintain safe harbor status.
