Ascertia provides high-trust PKI, digital signature, and trust services centred on the ADSS Server platform and the SigningHub e-signature service.

ADSS Server is a modular server platform providing core PKI and trust services including CA/RA, certificate issuance and validation, OCSP/SCVP, timestamping, long-term archiving, and advanced and qualified signature creation and verification. It is used by enterprises, governments, and TSPs as the cryptographic engine behind digital signing, eID validation, and secure transaction services.

ADSS Signing Server is a dedicated server for creating and verifying long-term digital signatures on documents and transactions, with web management, policy control, and detailed reporting. It supports individual and bulk signing when combined with ADSS Auto File Processor and client SDK.

ADSS Web RA Server is a web-based registration authority for enrolment and lifecycle management of user and server certificates, including configurable workflows, vetting forms, and subscriber agreements. It supports multi-tenant operation for service providers managing multiple enterprise accounts.

SigningHub is a cloud or on-premises digital signing platform for document preparation, workflow, approval, and creation of legally binding advanced and qualified e-signatures, including remote signing with HSM/QSCD. The platform provides audit trails, multi-user workflows, mobile-ready browser access, APIs, and connectors for SharePoint and Salesforce, with compliance aligned to eIDAS, ESIGN, and UETA regulations.

ADSS SAM Appliance delivers Signature Activation Module capabilities for secure, standards-compliant remote signing, evaluated to Common Criteria EAL4+ against EN 419 241-2 for eIDAS qualified remote signatures.

Ascertia's stack is often combined with HSMs such as Thales Luna for key protection and qualified signature services.
