Disig

What Disig does

Disig a.s. is a privately held joint-stock company established in Bratislava, Slovakia in 2006, operating as an accredited trust service provider and certification authority under the EU eIDAS Regulation (910/2014). The company designs, develops, and operates a portfolio of electronic signature, public key infrastructure (PKI), and cybersecurity products serving primarily Slovak government, enterprise, and individual customers, with EU-wide reach enabled by its eIDAS accreditation. Its product portfolio spans three core areas: electronic signature products (Disig Desktop Signer 4.0 with mobile signing, Web Signer, Batch Signing, Long-term Archiving, qualified certificates, qualified time stamps), enterprise server solutions (QES Portal, QES Signer, Enterprise Signer, PDF Signer, KeyPoint cloud signing, eArchive, eRegistry, OCSP Responder, Validation Authority, TSA Signer, CA Signer), and security services (cybersecurity audits, NIS2 compliance consulting, PKI implementation, ISO 27001 implementation, risk analysis).

The underlying technology is built on certified cryptographic infrastructure, including Thales nShield HSM integration for secure key storage, Common-Criteria-compliant components, and NBÚ SR-certified software (OCSP Responder as 'Software for Trustworthy System', KeyPoint for qualified signature key management). The platform supports integration with enterprise identity stacks (SAML 1.1/2.0, OpenID Connect, WS-Trust, WS-Federation, Microsoft Crypto API, PKCS#11) and document management systems (SharePoint, Alfresco). Disig operates multiple consumer and enterprise portals including the free public signing portal zep.disig.sk (35,000+ users), qesportal.sk, eidas.disig.sk, eshop.disig.sk, and opensource.disig.sk.

Disig generates revenue through four streams: recurring subscription revenue from certificate issuance (S/MIME, authentication, TLS/SSL, qualified certificates), one-time enterprise software licenses for server solutions, professional services revenue from security consulting and compliance work (NIS2, ISO 27001, PKI implementation), and hourly technical support/training. Pricing is predominantly low per-unit (€17–€193 per certificate) with higher-value enterprise contracts for QES Portal, KeyPoint, OCSP Responder, and consulting services. The company maintains seven ISO certifications (9001, 20000-1, 22301, 27001, 27701, 14001, plus Common Criteria and CEN/TS 419241), operates from a single Bratislava headquarters, and partners with global technology vendors including Microsoft and Thales as core partners alongside Cisco, Dell, Veeam, Check Point, Forcepoint, and Entrust.
