What Certum does

Certum is a European Certification Authority operating Public Key Infrastructure (PKI) services under eIDAS regulation, providing digital certificates and electronic signature solutions to enterprise and SMB customers worldwide. The company was founded around 1991 and is operated as a brand/business unit of Asseco Data Systems S.A., a Polish public limited company headquartered in Gdańsk and listed on the Warsaw Stock Exchange; Asseco Data Systems is part of the Asseco Group, which operates in 54 countries with approximately 30,000 employees. Certum's product portfolio covers SSL/TLS certificates (DV, OV, EV variants), qualified electronic signatures, code signing certificates, S/MIME certificates (Mailbox, Individual, Sponsor, Organization tiers), document signing certificates, electronic seals, and the newly announced CertumSign Platform for document signing workflows. Supporting tools include the SimplySign mobile signing app, Webnotarius electronic document verification service, proCertum SmartSign desktop software, ACME/Certbot automation, and a Certificate Discovery service.

The company is differentiated by regulatory credentials that are difficult to obtain — Qualified Trust Service Provider status under eIDAS, QSCert and WebTrustSM/TM certifications, listing on the EU Trusted Service Providers List, and inclusion on the Adobe Approved Trust List — enabling legally binding electronic signatures across the EU. Operational infrastructure is located in the EU with a guaranteed 99.9% service uptime. Technical operations are anchored in Szczecin (CERTUM PCC, the primary certification authority) and Gdańsk (the registered office of Asseco Data Systems).

Revenue is generated primarily through subscription-based recurring certificate sales, including SSL/TLS, electronic signatures, code signing, and S/MIME certificates, plus channel revenue from the 300-authorized-reseller network. Pricing is quote-based rather than publicly disclosed. Go-to-market combines a direct e-commerce storefront (shop.certum.eu) for SMB/individual buyers, the 300-reseller channel for mid-market, and dedicated enterprise sales for large customers including Santander Consumer Bank, BNP Paribas Lease Group, Inpost, Polsat Plus Group, Echo Investment, and the Polish Office of Technical Inspection (UDT).
