Welcome to VDI

In today’s increasingly complex international environment, VDI is committed to delivering exceptional security and intelligence solutions tailored to the specific needs of each of our clients.

We have documented success in international operations across a wide array of security issues, from the design and implementation of field security infrastructure for supranational institutions to sensitive operations on behalf of foreign government clients. We take pride in our history of producing results for problems that were often viewed as intractable. VDI delivers specific, cogent solutions that are measured in operational effectiveness and reduced risk.

VDI is operationally oriented; we design, develop, and deliver real results. Our goal is not to deliver a finished product and move on to the next assignment, but to deliver a lasting solution, on time and on budget, that will serve as the basis for the long-term relationships that have become the trademark of VDI. We hope to establish the same relationship with you.
