ProCircular Auditor Profile

ProCircular is a cybersecurity consultancy founded in 2016 by Aaron Warner and headquartered in Coralville, Iowa, with additional offices in Des Moines and Minneapolis. The firm has grown quickly since launch, earning Inc. 5000 recognition, and its founder was named an SBA Small Business Person of the Year for Iowa.

The company's compliance practice covers PCI DSS and HIPAA compliance, ISO 27001 support, and broader governance, risk, and compliance (GRC) work, alongside a strong technical bench in penetration testing, security strategy, digital forensics, SIEM, and managed detection and response (MXDR). It also maintains a niche in life sciences security and expert witness engagements.

As a boutique Midwest firm with a few dozen employees, ProCircular best serves small and mid-market organizations in healthcare, finance, manufacturing, and education that want hands-on regional consultants for both compliance assessments and offensive security testing.
