Software and Technology Auditing

I completed a recent audit to a government institution called “SINAP,” which refers to the National Property Institute of Honduras.  This is a major software project with millions of lines of code,  managing TeraBytes of geospatial information, and modern databases.  The audit consisted in reviewing their Java code base, .NET systems, HTML/CSS, and many processes that  handled thousands of transactions. The software deals daily  with property titles and is part of the digital marketplace of Honduras. The audit was a success and we expect to help more institutions on that front.
