DURHAM, NC, UNITED STATES, August 13, 2026 /EINPresswire.com/ — Drummond Group, LLC, a reliable authority on interoperability and security testing for B2B and B2G software, has declared the successful conclusion of its 2026 AS4 interoperability test event. Six products from four distinct vendors proved their adherence to AS4 specifications: Axway, CData Software, Cleo, and IBM Corporation.
Drummond’s AS4 testing assesses compliance with the AS4 specification using an extensive test matrix. The products under evaluation were Axway B2Bi 2.6 and Activator 6.1, CData Arc 26.3.9678.0, Cleo Integration Cloud (Cleo LexiCom, Cleo VLTrader, and Cleo Harmony version 6.0), IBM DataPower Gateway V11.0, IBM webMethods B2B module for AS4 10.1, and IBM webMethods B2B SaaS 11.2.80. Every product passed testing over both HTTP and HTTPS connections, showcasing interoperability across various communication protocols.
Drummond’s testing approach utilizes InSitu, a proprietary full-matrix framework that automates the execution of test cases while lessening the coordination burden on participants. This method enables vendors to focus on debugging their implementations rather than managing testing logistics. Those new to the program receive extensive technical support from Drummond during the pre-certification phase, guaranteeing that products satisfy InSitu requirements before formal testing begins.
The certification procedure builds on a well-established regression testing methodology. Every test event runs multiple automated cases against live implementations, identifying interoperability problems before products enter production. This approach safeguards vendors’ customers by ensuring that certified products function dependably across AS4 deployments.
“AS4 conformance across these six products demonstrates real interoperability at scale,” said Patrick Paschall, Director, Information Security & Interoperability Services at Drummond. “When vendors successfully test against this breadth of implementations, buyers gain confidence that AS4 will work reliably in their environment. That confidence matters as adoption accelerates globally.”
The complete AS4 Final Report, the full list of newly certified products, and test registration information are available on the Drummond website at https://www.drummondgroup.com/certified-products/b2b-interoperability/#as4.
About AS4
AS4, an OASIS B2B messaging standard, was finalized by the OASIS ebXML Messaging Services (ebMS) Technical Committee. The intent and purpose of the development of AS4 was to define a simplified Conformance Profile of the ebMS v3.0 specification that would serve as a B2B on-ramp for Web Services document exchange.
