A-Trust

What A-Trust does

A-Trust GmbH is an Austria-based qualified trust service provider (QTSP) founded in 2000 that delivers eIDAS-compliant digital identity, electronic signature, and trust services across the European Union. The company operates the ID Austria platform — Austria's state-endorsed digital identity system with over 5 million active users — along with its predecessor Handy-Signatur, xIDENTITY for non-Austrian EU citizens, and a comprehensive portfolio of qualified electronic signatures (QES), qualified electronic seals (a.sign Seal Qualified/Advanced/EPREL/PSD2/Amtssignatur), qualified timestamps with Long-Term Validation, and registration cash register certificates for Austrian RKSV compliance. The technical architecture rests on Public Key Infrastructure (PKI) with certified Hardware Security Modules (HSM) hosted in high-security data centers, where private signature keys can be used but never exported.

The company serves four primary customer segments: enterprises (Signatur-Box, Hash2Sign Software, Hash-Signing CSC, API integrations); the public sector (Amtssignatur, Dienst- und Gemeindeausweise, government-grade signature solutions); private individuals (ID Austria, Handy-Signatur, A-Trust Signatur App); and integration partners (DocuSign, Adobe Acrobat Sign, MOXIS, sproof, DSwiss, PXL Vision, Nect, WebID, Authada). Revenue is generated through a hybrid model combining recurring subscription fees for enterprise signature solutions, one-time and multi-year certificate issuance fees for company seals (e.g., EPREL seal at €800 for five years), hardware sales (signature cards, FIDO tokens), pay-per-minute professional support (€1.09/min), and partner-driven revenue through API integrations. A wholly-owned German subsidiary, A-Trust Vertrauensdienste GmbH in Mönchengladbach, supports the DACH market expansion. Distribution combines direct enterprise field sales, a self-service webshop, registration officers within customer organizations, and a multi-tier channel partner network.

A-Trust operates with 11-50 employees and maintains an Austrian ownership heritage rooted in the country's banking sector (Raiffeisen Zentralbank, savings banks, cooperative banks), the Austrian Economic Chamber, the Austrian National Bank, and telecommunications partners. Current leadership comprises Managing Directors Ing. Dr. Markus Vesely and DI Sven Glöckner, who have jointly led the company since 2007. The firm celebrates its 25th anniversary in 2025 and holds ongoing eIDAS QTSP certification audited by A-SIT and RTR, positioning it for early capture of the upcoming EU European Digital Identity Wallet (EUDI) framework through its consulting practice.

Scale indicators10 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Authada: German identity verification provider using NFC-based eID (nPA), an integration partner for A-Trust's German market. A niche player in identity proofing that complements A-Trust's qualified signature issuance workflow.
• WebID Solutions: German video-identification provider for QES issuance, integrated with A-Trust for customer onboarding. A specialized KYC/identity verification peer focused on the EU regulatory e-signature onboarding chain.
• sproof: Austrian signature platform that deepened its A-Trust partnership in June 2025 by integrating ID Austria into its eID-Hub. A regional emerging player in document workflow signing with overlapping enterprise and government target customers in Austria.

Broad incumbents

• DocuSign: Global leader in electronic signature and contract lifecycle management. Direct integration partner with A-Trust for QES capabilities in the DACH region; competes broadly in the same enterprise e-signature category but is a horizontal SaaS incumbent rather than a specialized QTSP.
• Adobe Acrobat Sign: Enterprise e-signature solution within Adobe's document cloud, integrated with A-Trust for qualified signatures. Comparable on the document-signing user experience layer but relies on specialized QTSPs like A-Trust for EU regulatory compliance.

Direct peers

• InfoCert: Italian QTSP (part of Tinexta Group) providing qualified electronic signatures, digital identity, and trust services across Europe. A comparable European eIDAS QTSP with overlapping product categories and enterprise/government focus.
• D-Trust (Bundesdruckerei Group): German QTSP subsidiary of Bundesdruckerei, providing qualified signatures, seals, and timestamps with similar eIDAS-compliant infrastructure. Direct competitor in the German market where A-Trust operates through A-Trust Vertrauensdienste GmbH.
• Namirial: European trust service provider offering qualified electronic signatures, electronic seals, and identity verification across multiple EU markets. Listed as an A-Trust partner but also a direct competitor in pan-European QTSP tenders, particularly in Italy and broader EU.
• MOXIS: Austrian and German signature workflow platform that integrates A-Trust for QES but also competes as a signature platform itself in the DACH enterprise market, with similar multi-party signing orchestration capabilities.
• Swisscom Trust Services: Swiss-based QTSP providing qualified electronic signatures and trust services across Europe. Comparable eIDAS-compliant offering with similar integration partner model and enterprise/government customer base in DACH and broader EU.
