Salzburg/Vienna, June 15, 2026 – The Salzburg-based RegTech company sproof and A-Trust, Austria’s leading trust service provider, are taking their collaboration to a new strategic level. As an official integration partner and established ID Austria service provider, sproof is integrating ID Austria even more deeply into its digital signature workflows. In doing so, both companies are sending a clear signal in support of expanding digital sovereignty and offering a legally compliant alternative to U.S. providers.
In the digital business world, trust is the foundation of every transaction. While U.S. providers are facing increasing regulatory pressure due to the Cloud Act and non-transparent data transfers to third countries, sproof and A-Trust guarantee a 100% European value chain. This official partnership marks the next logical step toward making the use of qualified electronic signatures (QES) easier than ever before for businesses and end customers.
Efficiency for the Business Community
The partnership aims to streamline complex signing processes in highly regulated industries such as banking, the energy sector, and public administration. sproof serves as a highly specialized expert in mapping and orchestrating even the most complex signing and approval processes. Through both its seamless, developer-friendly API and its intuitive user interface (UI), sproof positions itself as the number-one solution for all digital workflows within an organization. As an established Qualified Trust Service Provider (QVDA), A-Trust brings the highest level of regulatory compliance to the table. A-Trust’s qualified signatures are fully recognized by the government, forgery-proof, and legally equivalent to handwritten signatures.
“Our partnership combines the highest legal and technical standards with excellent usability. A-Trust provides its regulatory expertise and many years of experience in developing seamless, highly secure, and legally valid signature processes throughout the EU, and in return benefits from integration into sproof’s eID Hub. Together, we can thus help the local economy become less reliant on non-European cloud services.” – Dr. Markus Vesely, CEO of A-Trust
Together, the partnership aims to drastically speed up complex signature processes in highly regulated industries such as banking, legal services, and public administration. Thanks to deep technical integration, media breaks are completely eliminated; identity verification takes place in real time directly within the sproof platform.
“We see ourselves as enablers for companies that want to take the next step toward digital maturity,” explains Dr. Clemens Brunner, CEO and co-founder of sproof. “Through our official integration partnership with A-Trust, we’re reducing complexity for end customers. The goal is to make government-verified identities so easy to use that digital signatures become the standard. Together, we’re proving that technological excellence and European values aren’t a contradiction, but rather a competitive advantage.”
Legal certainty without compromise
sproof enables true interoperability while meeting the highest European legal standards. By seamlessly connecting the most important qualified trust service providers (QTSPs) across Europe via the sproof eID Hub, the platform offers maximum flexibility for cross-border business processes. The ability, for example, to use the existing ID Austria to create qualified electronic signatures directly in Austria sustainably strengthens sproof’s market position throughout the DACH region and on an international level. As an established and government-recognized partner, A-Trust acts as a reliable technological backbone behind the scenes.
This regulatory excellence is complemented by an uncompromising hosting commitment: Cloud hosting that is 100% based in Europe is no longer just an optional quality feature; for data-sensitive companies in the B2B sector, it is increasingly becoming a mandatory requirement for effectively countering access requests under third-country laws such as the U.S. Cloud Act.
“Austria’s digital transformation must not be built on foreign server infrastructure,” emphasizes Dr. Fabian Knirsch, CEO and co-founder of sproof. “Our partnership with A-Trust is the result of years of joint development. We’re not just integrating a technology; we’re building an infrastructure for true digital trust. Anyone who relies on sproof and A-Trust today protects their data from access by third countries and ensures full eIDAS compliance.”
