What intarsys does

intarsys GmbH is a German software company founded in 1996 and headquartered in Karlsruhe, with a regional branch in Pratteln, Switzerland. The company develops on-premises software products for electronic trust services — specifically the creation, validation, and long-term preservation of qualified electronic signatures, seals, and timestamps. Its product portfolio, marketed under the Sign Live! brand and the proNEXT sub-brand, spans three deployment architectures: web-based components (Sign Live! cloud suite gears, validator, and bridge), server-based solutions (signature server, validation server, and proNEXT Archive Manager), and workstation-based clients (Sign Live! CC client single, batch, komfort, and validation client). The software is built on a stack of cryptographic and regulatory standards, including eIDAS regulation, Swiss ZertES, German VDG, BSI TR-03125 (TR-ESOR), ETSI, and the Cloud Signature Consortium (CSC) standard API, with products independently tested and certified, including the TeleTrusT "IT Security made in Germany" seal.

The technology integrates with a broad ecosystem of trust service providers (D-Trust, TeleSec, Swisscom All-in Signing Service, Bundesnotarkammer, medisign, DGN), card readers (REINER SCT, CHERRY, signotec, WACOM), and vertical applications including DATEV accounting software, GekoS Bau+ for construction permits, and Nextcloud. Specialized editions exist for DATEV environments (Sign Live! CC DATEV-Edition, co-developed with DATEV) and for the German savings banks (Sign Live! CC Sparkassen-Edition, commissioned by DSGV).

intarsys generates revenue primarily through runtime software licenses with defined expiration dates, annual maintenance and support contracts, and professional services for enterprise deployments. The company serves four primary verticals: public administration (OZG compliance, e-government), the construction industry (digital building permits, XBau standard), auditors and tax consultants (DATEV-based accounting and tax document signing), and healthcare (eHBA qualified signatures). Distribution combines direct sales via the company website and a dedicated chipkartenleser-shop.de storefront with channel sales through the DATEV partner ecosystem, the Nextcloud app marketplace, and trust center partners. intarsys operates as a wholly-owned subsidiary of the procilon GROUP, a German conglomerate focused on PKI and digital trust services.

Scale indicators2 records

Recent moves6 records

Expansion highlights6 records

Direct peers

• DocuSign: Global e-signature and digital agreement management leader with strong EMEA presence. Directly comparable as a core electronic signature platform targeting enterprise and regulated workflows, though it competes at much larger scale and is primarily cloud-native.
• Skribble: Swiss-based eIDAS-compliant e-signature provider headquartered in Zurich. Closely comparable in DACH focus, eIDAS/QES product positioning, and target customer mix of regulated SMBs and mid-market enterprises.
• Namirial: Italian-headquartered digital trust services and e-signature provider operating across Europe. Comparable in eIDAS-compliant qualified electronic signature/seal products, trust service provider partnerships, and a multi-country EU go-to-market model.
• DigiCert: Major global PKI and digital certificate authority with trust services relevant to eIDAS, including digital signatures and timestamping. Comparable in providing the underlying certificate/trust infrastructure that eIDAS-compliant signature software like intarsys relies on.
• GlobalSign: PKI and digital identity provider offering qualified electronic signatures under eIDAS through its Atlas platform. Closely comparable in being a digital trust services vendor serving EU regulated workflows, though GlobalSign is significantly larger and more international.
• Sectigo: PKI and certificate lifecycle management provider offering digital signatures and eIDAS-aligned trust services. Comparable in serving certificate-driven signature/seal workflows for enterprise and developer audiences.

Broad incumbents

• Adobe (Acrobat Sign): Adobe Acrobat Sign is the e-signature arm of Adobe's broader Document Cloud platform. Comparable as a regulated-workflow-capable e-signature tool, but Adobe is a broad incumbent spanning content, marketing, and document tools beyond intarsys's narrow trust-services niche.
• Entrust: Identity, PKI, and secure transaction technology vendor offering signature solutions and HSMs used in qualified signing flows. Comparable in PKI/HSM-backed trust service components, but Entrust is a broad incumbent with payment, identity, and border control lines.
• Thales: Thales (including the former Gemalto digital security business) provides PKI, HSMs, and identity management underpinning eIDAS-compliant trust services. Comparable in providing foundational certificate/HSM technology that qualified signature solutions like intarsys plug into, but as a broad incumbent across defense, aerospace, and digital identity.

Regional players

• Bundesdruckerei: German state-backed secure identity and document company operating D-Trust as a trust service provider. Comparable as a German-based DACH eIDAS trust services ecosystem player; intarsys integrates with D-Trust, making Bundesdruckerei both a partner and a regional competitor with vertical reach.
