What's in a Name . . .


The word nGran comes from the combination of two concepts: networking and granularity. This means that our solutions consider the IT models as well as the skills of the people who administer the networks, the processes used to safeguard the information, and the security tools used to support the IT infrastructure.


Company History


nGran was founded in January of 2002. Since that time, it has operated as a profitable consultancy offering professional services and a variety of system, application, and network security analysis tools. The tools have been developed to identify and prevent complex network security attacks based on behavioral techniques that identify network security anomalies in real time, block attacks at the point of origin, and permit the secure correlation of complex network security problems.

nGran also markets and supports focused development and security services to Fortune 2000 corporations, federal and state governments through direct sales and support as well as channel partners.
