TNS Completes Acquisition of BT’s Radianz Business to Expand Global Financial Markets Connectivity
Transaction Network Services (TNS) has completed its acquisition of BT’s Radianz business, bringing together two long-standing providers of financial markets connectivity as institutions continue to prioritise network resilience, venue access and infrastructure diversification.
The deal adds Radianz — a secure global connectivity network that has served the financial community for more than two decades — into TNS’s Financial Markets offering, expanding TNS’s access, reach and service capability for clients worldwide.
The acquisition is positioned as a strategic consolidation move in financial market infrastructure, where connectivity providers increasingly compete on breadth of access, low-latency performance, and the ability to deliver secure, mission-critical communications across multiple venues and counterparties.
Radianz Joins TNS Financial Markets Offering later than 20+ Years of Venue Connectivity

TNS said the combination will expand client access while maintaining the diversity institutions rely on to manage operational risk. Tom Lazenga, General Manager of TNS Financial Markets, described the completion as a milestone for both firms and their clients.
“Today marks an significant milestone for TNS and our clients as we combine the strengths of two established leaders in financial connectivity,” Lazenga said. “We look forward to delivering expanded access to markets, counterparties and applications, while maintaining the network and platform diversity that institutions rely on for resilience and choice.”
The emphasis on “network and platform diversity” is particularly relevant as market participants face increasing operational resilience requirements and regulatory scrutiny around concentration risk. Connectivity has become a critical layer of market infrastructure, and firms are increasingly viewking redundant routes, multi-provider access and scalable service models.
