RSH Consulting, Inc. is dedicated to helping clients strengthen their IBM z/OS Enterprise Server security by fully exploiting all the capabilities and latest innovations in RACF. Our combined backgrounds in security, systems programming, applications development, and auditing enable us to comprehend and address even the most complex technical and managerial security issues. Better still, we can communicate effectively with all parties involved to successfully resolve these issues and help you convince management to support your objectives. All our professionals have at least two decades of personal, hands-on, real-world experience in securing mainframe systems with RACF.


RSH Consulting, Inc. was established in 1992 as an independent, veteran-owned consulting firm specializing in information system security, audit, and control. We have conducted security reviews, implemented control enhancements, and provided security training for RACF, CA Top Secret, and CA ACF2, and in the beginning, for Windows NT and Banyan VINES. The primary focus and vast majority of our business, however, has been providing RACF professional services.


Over the years, we have delivered RACF services to a diverse set of clients across a wide spectrum of industries. In every case, we have successfully tailored our services to their unique requirements. The industry groups for whom we have done the most work include:


Payment Card Processors

Insurance Companies


Financial Services Firms




Retail Firms


Technical Training Firms

System Integrators

Professional Associations


You can rely on RSH Consulting for timely, practical, cost-effective solutions. It is no surprise that our clients return to us repeatedly whenever they need further assistance.
