What CRYPTAS does

CRYPTAS International GmbH is an Austrian private limited company founded in 2003 and headquartered in Vienna, with additional offices in Graz, Düsseldorf, Hengelo, and Stockholm. The firm specializes in PKI-based cryptographic trust services and eIDAS-compliant electronic signature solutions delivered under its primesign product brand. Its core technology stack combines public key infrastructure, qualified trust services, and cloud-based remote signing, with native support for European government electronic identities including ID-Austria and the German Personalausweis. CRYPTAS holds qualified trust service provider status under the EU eIDAS regulation and offers specialized compliance tooling for the Austrian cash register regulation (Registrierkassenverordnung / RKSV). In June 2025 the company was acquired by India's eMudhra Limited (NSE: EMUDHRA) and now operates as a wholly-owned European subsidiary.

The product portfolio spans individual online signing (primesign Sofort-Signieren), enterprise signature workflow platforms (primesign ENTERPRISE and SIGNATURE SERVER), remote signing services (primesign REMOTE SIGNING), verified business certificates and seals (primesign SEAL), and Austrian cash-register compliance products (primesign RKSV), together with developer APIs (Document Signing API, Hash Signing API, Registrierkassen API) targeted at OEM integrators. Customer segments span individuals, enterprise organizations, OEM integrators and resellers, and regulated industries, with integrations into Adobe Acrobat Sign (individual and enterprise tiers) and the Fabasoft enterprise content management suite as primary embedded distribution channels. Reported scale metrics include users from 165+ nationalities, millions of transactions per day, and 99.98% uptime.

CRYPTAS generates revenue through four primary streams: recurring subscriptions for individual online signing accounts, usage-based pricing for API and OEM integrations, perpetual and subscription enterprise software licenses for ENTERPRISE, SIGNATURE SERVER, and RKSV appliances, and SLA-backed managed services for trust centers and power users. Pricing is quote-based for enterprise customers and not publicly disclosed, while individuals can purchase through the cryptoshop.com storefront and self-serve sign-up at prime-sign.com. The company sells via direct enterprise field sales, self-serve online channels, an e-commerce storefront, and OEM/API partnerships, with operations currently focused on the DACH region and the Nordics under private ownership.
