Peter,

New capabilities are being added to offer an Identity Provider (IdP) for our IPDX product using

XMPP which will  identify devices and users that are connected to a network.  This capability

will offer the ability to assure that a device or users is authorized to participate in a network

and be able to share information with multiple users, devices, and applications.

The following article entitled "Protocol Transformation defense against cyber-attack" will appear

in CONTROL magazine in the June 2012 issue. 

See latest updates that now includes Android support:  http://www.mact-usa.com. 

The newest version will also include changes supported in Window 8 and Apple IoS due out next month.

Protocol transformation eliminates penetration of viruses and can control read/write access and policy administration on a packet level.   This capability prevents certain registers from being accessed or changes without authorization.   This capability is inherent in the approach which does not require a VPN.  Most significantly the end devices do not have to  include virus protection even when accessed via the Internet.  All traffic is secured end-to-end using Transport Layer Security (TLS).  

The following is an article in International Cement Review (ICR) May 2012 entitled "XMPP Revisited":
