Networks

There is a growing trend for electronic devices and systems to be connected through a variety of networks. There are also increasing commercial pressures for disparate company networks to be inter-connected, often using the internet. These pressures expose both corporate and operational information to increasing threats of electronic attack on systems previously held to be secure.

Strong links forged with network operators, infrastructure-owners and end users enable CPNI to deliver authoritative and timely advice.
