Our Business

Who we are


Spirent helps our customers manage the complexity of their devices, networks and services, enabling them to keep the promises they make to their customers while reducing cost. We provide innovative test and assurance solutions and trusted expertise that allow our customers to bring better quality products and services to market faster, to automate the turn-up of new services and to proactively identify and resolve problems in their production networks.

Across every one of our businesses we are accelerating the transition of testing and evaluation of devices, network equipment and applications from development labs to the operational network, and evolving from a product-centric to a customer-centric organisation. We will continue to innovate towards fully automated testing and autonomous service assurance and analytics solutions.
