Brazil’s B3 taps TNS for managed hosting, market data, and connectivity

Rick Steves

“Trading execution, speed and infrastructure reliability are mission critical for expanding global access to B3, which is a vastly underserved market for traders outside of South America.”

Transaction Network Services (TNS) has partnered with B3 S.A., Brazil’s largest stock exchange. The partnership focuses on colocation services, enhancing global financial market solutions. This initiative promises ultra-low latency trading through TNS’s network.

TNS now provides managed hosting, market data, and exchange access for B3. The services include Layer 1 connectivity, crucial for trading operations in equities, derivatives, and commodities. This expansion meets the growing demand from international traders for efficient connections with B3.

“Trading execution, speed and infrastructure reliability are mission critical”

Jeff Mezger, TNS’ Vice President of Product Management for Financial Markets, noted the importance of trading speed and infrastructure reliability. “Trading execution, speed and infrastructure reliability are mission critical for expanding global access to B3, which is a vastly underserved market for traders outside of South America. The challenge of acquiring and installing hardware in Brazil, a process that often spans several months, is bypassed with TNS. With pre-established data center equipment on-site that is fully operational, we can deliver our full suite of services immediately, reinforcing our commitment to empowering global traders with unparalleled efficiency and access. The combination of our local presence in Brazil and decades of financial exchange experience make TNS the ideal partner to connect clients to the B3 exchange.”

B3 hosts nearly 500 companies, with recent economic growth and regulatory reforms attracting more investments. Brazil’s projected 3.2% GDP growth in 2023 reflects this economic expansion. TNS’s collaboration with B3 aligns with these developments.

TNS offers Layer 1 ultra-low latency solutions and cloud trading infrastructure. Their experienced team aids clients in data center and market data deployments, strengthening TNS’s presence in South America. TNS recently opened a new headquarters in João Pessoa, Brazil.

With over 100 employees in Brazil, TNS has maintained a presence there since 2019. Their ongoing collaboration with B3 began in 2021. This expansion marks a significant milestone in TNS’s growth in Latin America.

TNS connects over 5,000 financial community endpoints globally. Their infrastructure includes 125 points-of-presence worldwide. TNS specializes in connectivity, colocation, cloud, market data, and VPN solutions, catering to the financial market’s needs.

Their Infrastructure-as-a-Service (IaaS) offerings are monitored continuously. TNS’s Network Operations Centers operate 24/7 in the US, UK, Australia, and Malaysia. For more information, TNS’s website offers detailed insights into their financial solutions.


The move comes on the heels of the latest enhancement to the TNS network with the introduction of multiple 100 Gbps circuits, a strategic move designed to support the Options Price Reporting Authority (OPRA) expansion.

This upgrade is set to manage the anticipated increase in market data volume following OPRA’s transition to a more extensive multicast network. TNS, known for its ultra-low latency dark fiber backbone, assures comprehensive coverage and efficient management of US equity options market data.

The company’s network infrastructure is not only built to handle current data volumes but also to scale seamlessly with the future addition of new market data feeds. By leveraging its high-bandwidth capabilities, TNS can facilitate cost-effective and reliable market data delivery for customers, positioning itself as a leader in market data solutions.

The network upgrade aligns with TNS’ history of delivering cutting-edge infrastructure, ensuring that its clients receive market data without disruptions. The 100 Gbps network support is a testament to TNS’ investment in state-of-the-art technology, ensuring their infrastructure is future-proofed and capable of accommodating the ever-growing demands of the financial markets.
