What D. Trust Certifikačná Autorita, a.s. (DTCA) does

D. Trust Certifikačná Autorita, a.s. (DTCA) is a Bratislava-based private company founded in 2002 that operates as a value-added reseller and authorized representative rather than a primary software developer. Its core business is the distribution of DITEC a.s. electronic signature products — D.Signer Suite, D.Bulk Signer (Start/Standard/Premium tiers), D.Viewer, D.Convert, D.PDF Signer, and the D.Signer Integration Suite — to Slovak end customers via its own e-commerce platform at dstore.sk, built on Odoo and processed through Stripe. The portfolio covers viewing, signing, and converting electronic documents in the ASIC, XAdES, and PAdES formats, including guaranteed conversion (zaručená konverzia) between electronic and paper formats with legal validity.

In parallel, DTCA is authorized to provide qualified trust services on behalf of První certifikační autorita, a.s. (I.CA) for the Slovak Republic under EU eIDAS Regulation 910/2014. This covers issuance of qualified certificates, qualified electronic time stamps, and a D.Bulk Signer pathway into Slovak government e-schránka (electronic mailbox) and ORSR (commercial register) interactions. DTCA's customer base is described as horizontal — businesses, organizations, and individuals requiring legally valid electronic signatures for B2B, B2G, and government communication — with no disclosed named enterprise customers or segment revenue split.

The commercial model combines a freemium entry point (D.Bulk Signer Start, free 182-day renewable license, viewing only) with paid Standard/Premium signing tiers and other add-on modules sold through the self-serve storefront. Pricing is subscription-based with automatic annual renewal, alongside one-time payment options. The company is privately held with 5 employees, no disclosed funding, no parent company, and operations confined to Slovakia.

Regional players

• InfoCert S.p.A. InfoCert is a major Italian qualified trust service provider under eIDAS, providing e-signature, digital identity, and certified email. While it primarily operates in Italy, it competes with DTCA's I.CA Secom-style trust services across the EU qualified e-signature market.

Broad incumbents

• Adobe (Adobe Acrobat Sign): Adobe Acrobat Sign is an enterprise e-signature and DTM platform with eIDAS compliance, broadly competing with DTCA's DITEC-powered solutions in the Slovak B2B segment as part of a wider document productivity portfolio.
• DocuSign: DocuSign is the global leader in e-signature and digital transaction management with eIDAS-compliant offerings in the EU. It competes with DTCA in the Slovak enterprise segment for cloud-based qualified electronic signature workflows.
• První certifikační autorita, a.s. (I.CA): I.CA is the Czech qualified trust service provider that DTCA represents in Slovakia. I.CA issues the qualified certificates and timestamps that flow through DTCA's I.CA Secom product, making it both a partner and a comparable operator in the EU eIDAS trust services market.
• Asseco Poland (e-signature solutions): Asseco is a large Central European IT group that supplies qualified e-signature and identity solutions across the region, including Slovakia-adjacent markets. It competes broadly with DTCA's enterprise and government-facing e-signature portfolio.
• DITEC a.s. DITEC is the upstream Slovak software vendor whose entire product portfolio (D.Signer Suite, D.Bulk Signer, D.Viewer, D.Convert, D.PDF Signer, D.Signer Integration Suite) DTCA resells. Same product set and same Slovak market, but DITEC owns the technology and is the direct upstream incumbent in the local e-signature stack.
