GIACT (now LSEG Risk Intelligence) and Trustpair both address bank account verification, but from fundamentally different angles. GIACT is a bank data API that tells you whether an account is open and active. Trustpair is a complete vendor fraud prevention platform that confirms who owns the account, monitors your entire vendor master file continuously, and gives finance teams the tools to act on every result. For enterprise AP and treasury teams, the difference is critical.
GIACT provides a transactional API: you send an account number and receive a status code (Accept, Decline, Accept with Risk, No Data Found). It tells you that an account exists. It does not tell you whether the vendor requesting payment is the legitimate owner of that account.
Trustpair goes further. Our platform combines external banking sources, network mutualization, payment history, secure callbacks, and micro-payment verification into a single, orchestrated evaluation engine, with a proprietary risk-scoring model that contextualizes each result. Finance teams get a clear, actionable risk assessment, not a raw API response to interpret.
In the US, GIACT/LSEG provides strong coverage of consumer and business bank accounts — it is one of the most recognized data sources in the US market. Internationally, LSEG’s Global Account Verification solution extends to 45+ countries.
Trustpair’s coverage goes further: external banking source coverage in 140+ countries, and complementary check coverage in 190+ countries — including dedicated sources in the US, China, France, the UK, Italy, the Netherlands, Belgium, Brazil, India, South Africa, Mexico, Poland, and Sweden. For enterprises with vendors across multiple geographies, Trustpair provides the broadest reliable coverage available on the market.
GIACT delivers its verification capabilities through a raw API, with no native connectors to ERP, TMS, or Source-to-Pay platforms. Integrating GIACT into enterprise workflows requires custom development work and ongoing engineering maintenance.
Trustpair easily adapts to any corporate environment thanks to a full range of connectivity options. Our solution adapts to your technical ecosystem via 20+ native connectors and a public API. We natively connect to the leading corporate Source-to-Pay, ERP, and TMS platforms.
Trustpair has the largest integration capabilities on the market, including exclusive partnerships with SAP, SAP Ariba, Ivalua, JAGGAER, Kyriba, Coupa, Provigis, and more.
We are a Silver status SAP partner and provide native connectors for SAP S/4HANA, SAP ECC6, and SAP Fiori, SAP certified and available on the SAP store.
GIACT (now LSEG) primarily serves financial institutions, banks, and fintechs, organizations that need to verify customer accounts for ACH, payment processing, or onboarding. It is not purpose-built for the vendor fraud prevention needs of enterprise finance teams.
Trustpair is the vendor fraud market leader in Europe and the US, trusted by 600+ corporate clients globally — including 40% of CAC 40 companies such as Air Liquide, Carrefour, Danone, Sanofi, and Société Générale. Our platform is purpose-built for large and mid-market enterprise finance teams — with dedicated pre-sales, customer success, fraud expert, and onboarding methodology teams included.
This makes Trustpair the best alternative to GIACT for enterprise vendor fraud prevention.
GIACT’s core product, gVERIFY®, confirms whether a bank account is open, active, and in good standing. This is account validation, a necessary hygiene check. But it is not account ownership verification. A fraudster can redirect payments to a real, open, active bank account, just not one that belongs to your vendor.
Trustpair’s evaluation engine confirms who owns the account, not just whether it exists. By combining external banking sources, network data, and secure callbacks with a proprietary risk-scoring engine, Trustpair delivers the highest standard of assurance available: confirmed account ownership, with the evidence trail to support it.
GIACT returns API response codes. What your team does with those codes, how to escalate, investigate, override, document, and resolve, is entirely up to you to build.
Trustpair’s case management hub is embedded directly in the platform and guides finance teams step by step whenever a vendor evaluation requires deeper analysis. It enables teams to collect information, track actions, and reach a documented decision, with full traceability at every stage.
GIACT is designed for transactional, point-in-time queries: verify an account before a payment is processed. It has no mechanism to monitor your vendor master file continuously or to alert your team when account details change between payment cycles.
Most vendor payment fraud does not happen at a transaction level — it happens through an undetected account change in the vendor master file, discovered only when a legitimate vendor reports a missed payment. Trustpair’s continuous audit module monitors your entire vendor master file daily, automatically surfacing any changes — whether from a legitimate update, a migration error, or a fraud attempt, before the next payment run is triggered.
GIACT’s verification capabilities are accessible through an API that requires in-house engineering work to implement, maintain, and connect to existing enterprise systems. There are no native connectors to ERP, TMS, or procurement platforms.
Trustpair offers native integration to the main enterprise ecosystem leaders, including SAP, Ivalua, JAGGAER, SAP Ariba, and Oracle. Native integrations guarantee a seamless experience and systematic controls directly inside your usual systems, without switching tools or building custom middleware.
As a Silver status SAP partner, Trustpair provides SAP-certified native connectors for SAP S/4HANA and SAP ECC6, available on the SAP store.

Payment fraud can have serious consequences for businesses, on top of direct financial losses. Damaged reputations, operational disruptions, severed business partnerships… That’s why businesses should implement fraud detection and prevention solutions to protect their processes and money.
Trustpair assesses the vendor (its localization, existence, etc), its banking data, and the correlation between the pair. Our software guarantees security throughout the entire procure-to-pay process: from vendor onboarding to vendor payments.
The override feature enables specific users to validate third-parties through their own process, by bypassing the usual Trustpair checks. This means all controls can be managed on the same platform, including the ones clients want to directly validate through their own process.
