SigningHub

What SigningHub does

SigningHub is a UK-headquartered (Ascertia Limited, London/Guildford) electronic signature platform that supports Basic, Advanced Electronic Signatures (AES), and EU Qualified Electronic Signatures (QES) compliant with the eIDAS regulation. Its core technology is a PKI-based digital signature engine built around the proprietary ADSS Server, featuring a complete e-Trust infrastructure with built-in Certificate Authority (CA), real-time Validation Authority (VA), and Time Stamp Authority (TSA) servers. The platform provides HSM-bound signing key protection, AES-256 encryption, WYSIWYS secure document viewing, long-term validation (10–20+ years), and integrations with Adobe AATL, Microsoft SharePoint, Salesforce, Microsoft Word, and national identity systems such as Singapore's SingPass.

The company's primary customer base is highly regulated enterprises — banks (Deutsche Bank, Capitec), governments (SARS South Africa, Portuguese Government, British Library, ANACOM), and global corporates (Shell, Vodafone, Siemens, HP, Deutsche Telekom/Orange) — requiring the highest level of trust and legal certainty. It also serves a long tail of SMBs and individual users through a self-serve cloud product. Revenue is generated through tiered subscription plans for the cloud service, one-time enterprise on-premise licensing, and a freemium trial-to-paid conversion motion, with a 100+ global partner network (Trust Service Providers, system integrators, HSM vendors) driving channel-led sales across 21+ countries.

SigningHub has accumulated an unusually deep regulatory and certification footprint for its size — first-in-world Common Criteria EAL4+ certification (EN 419 241-2), CEN CWA 14167-1, US FIPS 201/FPKI PD-VAL, FedRAMP, ISO 27001/27002/27018/9001, SOC 1/SSAE 16/SOC 2, PCI DSS Level 1, HIPAA/HITECH, and FDA 21 CFR Part 11. It operates regional offices in Dubai (sales), Singapore (APAC HQ), and Lahore (development), and is reported to secure multi-billion-Euro daily transactions for European Central Bank clearing systems — placing it as a niche, compliance-anchored competitor rather than a horizontal mass-market e-signature vendor.

Expansion highlights6 records

Direct peers

• DocuSign: Global leader in electronic signatures covering Basic, AES and via DocuSign Identify, Qualified Electronic Signatures under eIDAS — directly comparable cloud e-signature platform competing for the same enterprise and regulated-industry customers.
• Adobe Acrobat Sign (Adobe Sign): Adobe's enterprise e-signature product offering Basic, AES and AATL-trusted digital signatures with deep PDF integration; SigningHub explicitly highlights AATL interoperability and competes head-on in regulated-document workflows.
• OneSpan Sign: Long-standing competitor focused on banks and highly regulated industries with PKI-backed digital signatures, fraud detection and e-signature workflow — directly comparable regulated-industry target segment and technology stack to SigningHub.
• GlobalSign: Digital certificate authority offering both PKI trust services and e-signature solutions with AATL-qualified certificates — adjacent competitor that SigningHub partners with via Entrust/IdenTrust ecosystems and overlaps on Qualified Signature creation.
• Yousign: European eIDAS-compliant e-signature SaaS serving SMB and enterprise in France and beyond with QES capability — direct competitor in the EU e-signature market, particularly for French/Southern European deals.
• Namirial: Italian qualified trust service provider offering e-signature, e-delivery and digital identity solutions across EU markets with strong public-sector footprint — comparable EU QES vendor competing for the same regulated RFPs.

Emerging players

• Thales (Digital Identity & Security): Provides QSCD-certified HSMs (formerly SafeNet) underpinning SigningHub today, but also fields its own signing/workflow offerings; an enabling/competing peer on the trusted-device layer for qualified signatures.
• Cryptomathic: Provider of cryptographic e-signature infrastructure including the CryptoSign Server for qualified electronic signatures — technology-vendor peer targeting banks and governments with PKI-based signing, highly comparable to Ascertia's ADSS Server substrate.

Regional players

• LuxTrust: Luxembourg-qualified TSP offering eIDAS-compliant digital signatures and certificate services across financial and government segments — a regional peer in the EU QES/TSP market where SigningHub competes for regulated customers.

Broad incumbents

• Entrust Datacard: Broad incumbent in digital identity, PKI certificates and increasingly signing workflows; integrates with SigningHub for certificates but also competes at the higher stack for QES and identity proofing in regulated industries.
