What Zertificon Solutions does

Zertificon Solutions GmbH is a Berlin-based, privately held German IT security vendor founded in 2004 that provides centralized email encryption and digital signing solutions for business communication. Its core product, the Z1 SecureMail Gateway, operates as an SMTP proxy that processes company-wide email traffic to apply S/MIME, OpenPGP, and password-based encryption, with proprietary automation layers CertMagic® for certificate lifecycle management and GlobalCrypt® for partner-to-partner end-to-end encryption. The company also operates Z1 Global TrustPoint, an independent certificate search engine launched in 2006, and offers adjacent products Z1 SecureHub for secure large file transfer, Z1 Energy for EDI@Energy-compliant German energy market communication, and Z1 HealthSecure as a healthcare vertical bundle.

The product portfolio is delivered via three commercial models: a self-hosted Server edition with one-time onboarding fees, a SaaS edition (SMGW5) priced at €178–€910 per month across S/M/L tiers sized by user count and email volume, and an Enterprise tier with custom pricing for HSM-integrated and complex deployments. Distribution combines direct enterprise sales, transparent self-serve online purchase, the Azure Marketplace, and a partner network of resellers, technology integrators, and certificate authorities. Customers span regulated DACH enterprises and SMEs across insurance, energy, healthcare, legal, biotech, and public sector verticals, with stated penetration of more than 25% of the top 100 German companies by turnover and approximately 50% of the TOP 100 NIS2/KRITIS companies.

The business is positioned around regulatory compliance (IT Security made in Germany, ISO 27001, GDPR, NIS2, KRITIS, DORA, TISAX, EDI@Energy) and long-tenured customer relationships (multiple enterprise customers exceeding 15 years). No funding rounds, M&A activity, or disclosed revenue figures appear in the source material; the company appears to be an independently held, bootstrapped German Mittelstand vendor.
