TNS Introduces New DUO Customer Portal for Data Optimization

Transaction Network Services (TNS) has announced an upgrade to its TNS Data Usage Optimizer (DUO) with the introduction of a new interactive customer portal, aimed at helping financial firms gain greater visibility into their market data spending.

Also, the latest release builds on the initial launch of DUO in late 2024 and provides buy-side and sell-side firms with direct, on-demand access to subscription data. Through the portal, users can analyze vendor entitlements, identify unused services, and remove unnecessary costs without relying solely on external reviews.

Market data remains one of the largest operational expenses for financial institutions, while oversight can be complex due to fragmented systems and varied vendor contracts. The DUO portal addresses this challenge by transforming raw entitlement files into a centralized, user-friendly dashboard. This allows firms to quickly review usage patterns and pinpoint areas of excess spending.

TNS Introduces New DUO Customer Portal for Market Data Optimization

“Last year, we introduced DUO to solve a critical industry problem. Today, we’re putting the power to control market data costs directly into our customers’ hands,” said Tom Lazenga, General Manager of TNS Financial Markets. “The DUO portal empowers data managers and desk heads to instantly identify and act on potential savings.”

The portal represents the second major release of the DUO platform and offers a unified, global view of market data expenses. Key features include direct customer access for uploading vendor files and generating reports, advanced analytics for filtering data by user, location, or feed, and multi-site management tools for firms with international operations.

In addition, the system allows users to customize cost models by incorporating contract pricing, volume discounts, and regional fee structures. This helps organizations estimate potential savings more accurately and prioritize cost-reduction initiatives.

Moreover, according to Lazenga, the portal is designed to simplify the process of detecting wasted spend and improving internal oversight. He added that the new interface also supports TNS’s broader development plans, which include automated data feed provisioning and expanded support for additional market data providers.

So, with the launch of the DUO portal, TNS aims to give financial firms greater control over data-related expenses in an environment where cost efficiency remains a key operational focus.
