The North Texas Tollway Authority is seeking on-call internal audit support, primarily for information technology audits.
- **Government buyer:** North Texas Tollway Authority (NTTA), through Procurement Services and its Internal Audit Department.
- **Services requested:** As-needed internal auditing, including outsourced audits, staff augmentation, specialist support, and special projects. Work may cover cybersecurity, IT governance and controls, data governance, system implementations, technology operations, compliance, and occasional business-process or operational audits.
- **Notable requirements:** Respond to service requests within 10 business days; use documented risk-based audit methods and quality assurance; obtain NTTA approval of personnel; and follow applicable information-security protections.
- **OEMs and vendors:** No commercial OEMs or service vendors are named. NTTA is the government buyer.
- **Attachment discrepancy:** A separate attachment describes a dynamic budgeting and reporting tool for NTTA Finance. It gives no manufacturer, part number, or quantity and appears distinct from the internal-audit services request.
