The Ascension Seton Data Breach:

In March 2023, Ascension Seton, a well-known healthcare system in Austin, experienced a significant data breach on two of its websites: and These websites, which were managed by a technology service provider called Vertex, fell victim to malicious hackers who gained unauthorized access. As a result of this breach, sensitive personal information such as names, addresses, Social Security numbers, credit card details, and insurance information of users who had submitted data through these platforms was compromised. This incident highlights the critical importance for businesses to thoroughly evaluate the security measures taken by their third-party service providers.

The Role of Vendor Security Measures:

The data breach at Ascension Seton underscores the significance of ensuring that vendors and service providers have robust security measures in place. When businesses entrust their systems and client data to third-party service providers, it becomes essential to verify that these providers have implemented adequate safeguards. In this particular case, the breach occurred due to security vulnerabilities in Vertex's systems, emphasizing the need for businesses and owners to actively assess the security practices of their vendors. By conducting thorough due diligence, establishing clear contractual obligations, and regularly monitoring vendor security, businesses can mitigate the risk of data breaches originating from service providers.

Assessing Vendor Security:

To safeguard your business from potential data breaches originating from service providers, consider the following steps:

Conduct Thorough Due Diligence:

Before partnering with a vendor, conduct comprehensive due diligence to evaluate their security practices. Review their security policies, procedures, and certifications. Inquire about their vulnerability management, incident response protocols, and employee training programs.

Contractual Obligations:

Establish clear expectations and contractual obligations regarding data security in your vendor agreements. Define security requirements, including regular security audits, compliance with industry standards, and prompt notification of any breaches or vulnerabilities.

Regular Security Assessments:

Periodically assess your vendor's security practices through audits and evaluations. Consider engaging third-party cybersecurity experts to perform independent assessments to ensure thorough scrutiny.

Incident Response Preparedness:

Ensure that your vendors have well-defined incident response plans in place. Assess their ability to detect, contain, and respond to potential security incidents promptly. Align your incident response protocols with your vendor's to enable coordinated and effective incident management.

Ongoing Monitoring:

Continuously monitor your vendor's security posture by requesting regular security reports, conducting vulnerability scans, and maintaining open lines of communication regarding security updates and enhancements.


The Ascension Seton data breach serves as a poignant reminder of the critical role that third-party service providers play in maintaining data security. Business owners must proactively assess the security measures taken by their vendors, ensuring that adequate safeguards are in place to protect sensitive information. By conducting thorough due diligence, establishing strong contractual obligations, and regularly monitoring vendor security, businesses can minimize the risk of data breaches and better protect their customers' data.

Remember, your business's security is only as strong as the security practices of your vendors. Prioritize vendor security assessments, maintain open lines of communication, and fortify your defense against potential breaches.
