Ptech is a small corporation that makes a special kind of corporate software. It combines risk management and enterprise architecture, and its purpose is surveillance and intervention of business processes. For instance in a Bank it could detect suspicious (patters of) transactions, and if so desired it could intervene. It is a kind of process control software, except that it applies to an entire corporation. It is very exclusive and very expensive software, used by many large corporations and government agencies. It provides complete control over every kind of digital communication that's hooked up to it. It can involve such matters as interoperability between the FAA and NORAD.
The problem with Ptech is, is that it's heavily populated and financed by Saudi's who are also involved in financing of terrorism.
Ptech actually was raided by the FBI at some point, it has since changed its name to "Go Agile" (www.goagile.com).
Amongst Ptech's clients are: IBM, Federal Aviation Agency, Sysco, Motorola, Honeywell, Internal Revenue Service, ABN-AMRO, Sprint, United States Postal Service, House of Representatives, United States Senate, Executive Office of the President, Secret Service, Department of Navy, Air Force, NATO, Mitre, FBI.
