What SwissSign does
SwissSign AG is a Swiss Certificate Authority and Trust Service Provider founded in 2001 and headquartered in Glattbrugg, Switzerland, operating as a wholly-owned subsidiary of Swiss Post. The company builds and operates an X.509 public key infrastructure entirely on Swiss soil, geo-redundant and self-managed, issuing SSL/TLS certificates (DV, OV, EV — single-domain, wildcard, multi-domain), S/MIME certificates, and operating a ZertES-certified Trust Service Provider platform that delivers qualified (QES), advanced (FES), and simple (EES) electronic signatures and seals, organizational timestamps under RFC 3161, digital onboarding (FINMA/EPDG-compliant identity verification), and Verifiable Credentials aligned with the Swiss Trust Framework and EUDI Wallet.
The product suite spans Managed PKI (MPKI) with REST (OpenAPI V3) and ACME automation, Certificate Lifecycle Management (CLM) powered by Evertrust and integrated with AWS, Azure, GCP, F5, Kubernetes, Terraform, Ansible, and major MDMs, Private PKI for hybrid environments, and three digital-signature deployment models (web service, REST-API, on-premises with Hash-Signing). The 2022 acquisition of Sysmosoft added the Let's Sign enterprise e-signature solution used across hundreds of regulated-sector organizations.
SwissSign monetizes through (i) self-serve webshop sales of one-time SSL/S/MIME certificates, (ii) annual MPKI subscriptions with volume tiers and minimum commitments (CHF 300 OV / CHF 500 EV), (iii) digital signature Standard pay-per-package (CHF ~2.58–2.62 per QES) and Pro subscriptions (CHF 1,050 setup + annual + per-signature scaling), (iv) enterprise REST-API and on-premises signature contracts with custom proposals, (v) CLM managed services through partner-hosted or on-premise deployment, and (vi) digital onboarding and Verifiable Credential subscriptions. Distribution combines direct enterprise field sales, a partner/reseller channel (IT service providers, MSSPs, email-gateway and CLM vendors), and embedment inside third-party security platforms. Over 10,000 organizations worldwide — including PostFinance, Coop, Swisslos, GLKB, Universitätsspital Basel, and SEPPmail — rely on SwissSign.

SwissSign competitors and assessment
Company assessmentBroad incumbents
- Adobe Acrobat Sign: Adobe Acrobat Sign (formerly EchoSign/Adobe Sign) is a major enterprise e-signature platform integrated with Adobe Document Cloud and supports qualified electronic signatures in Europe. Competes with SwissSign on enterprise digital signature workflows, especially for legal, HR, and regulated document use cases.
- Thales (SafeNet): Thales provides PKI, hardware security modules, and digital identity solutions through its SafeNet portfolio serving enterprises, governments, and financial institutions. Broad incumbent competitor to SwissSign in private PKI, key management, and FIDO/PKI-based authentication for large organizations.
- DigiCert: DigiCert is the world's largest commercial Certificate Authority, offering TLS/SSL, PKI, and document signing at global scale. It is the most direct incumbent to SwissSign across SSL/TLS, MPKI, and document signing, competing on root ubiquity, brand, and enterprise reach where SwissSign competes on European data sovereignty.
- DocuSign: DocuSign is the leading global e-signature platform with eIDAS-qualified signatures via DocuSign Signature Appliance/Qualified. Broad incumbent competitor to SwissSign's Web/REST-API/On-Premises signature offerings in regulated enterprise and cross-border signature workflows.
- CyberArk (Venafi Machine Identity Security): CyberArk acquired Venafi to build the largest machine identity security platform, covering certificate lifecycle, code signing, and PKI posture management. Broad incumbent competitor to SwissSign's CLM offering (powered by Evertrust) in the enterprise certificate lifecycle automation category.
Direct peers
- OneSpan: OneSpan provides digital identity, e-signature, and authentication solutions with strong positioning in banking and regulated industries across Europe. Direct peer to SwissSign in qualified electronic signatures, authentication, and digital onboarding, with comparable vertical focus and compliance depth.
- Entrust: Entrust is a global PKI, TLS, and digital identity/security vendor serving enterprises and governments with certificate and identity solutions. Direct peer to SwissSign across enterprise PKI, certificate lifecycle, and identity verification, differing mainly by scale and US-headquartered governance.
- Sectigo: Sectigo (formerly Comodo CA) is a major global Certificate Authority offering SSL/TLS, S/MIME, and managed PKI with broad automation integrations. Direct peer to SwissSign across public certificate issuance, MPKI, and CLM via overlapping enterprise and channel partner ecosystems.
- GlobalSign: GlobalSign is a long-established CA and identity provider offering SSL, PKI, S/MIME, and digital signature services with strong European and APAC footprint. Direct peer to SwissSign across PKI-as-a-service, e-signature, and identity, with similar European data-residency messaging.
Emerging players
- Let's Encrypt (ISRG): Let's Encrypt, operated by the nonprofit Internet Security Research Group, issues free DV TLS certificates at massive scale via ACME. Competes with SwissSign's DV webshop tier on price; SwissSign's OV/EV and managed-PKI tiers compete less directly, but Let's Encrypt sets the floor on DV economics.
