Document Signing Certificates

All three produce legally binding digital signatures, the difference is whose identity is bound to each signature. IV (Individual Validated) embeds your verified personal name, for lawyers, accountants, doctors, consultants, and notaries whose signatures carry personal professional authority. OV (Organization Validated) embeds your organization's verified legal name, shareable across authorized staff and supports eSealing for automated high-volume signing. IV+OV (Sponsor) binds both identities into one signature, maximum non-repudiation for executives, regulated signatories, and any scenario where both personal and firm identity must appear on the document.

Yes. SSL.com document signatures are legally binding under the US E-SIGN Act, UETA (adopted in 49 US states plus DC), EU eIDAS (Advanced Electronic Signature qualifying tier), and equivalent electronic signature frameworks in the UK, Canada, Australia, and major jurisdictions worldwide. For FDA-regulated industries, SSL.com certificates support 21 CFR Part 11 electronic records and signatures requirements. All certificates are issued under CA/Browser Forum S/MIME Baseline Requirements with private keys protected by FIPS 140-2 Level 2+ hardware (YubiKey token or eSigner cloud HSM).

Not necessarily. You have two options: YubiKey FIPS token, a physical USB hardware token that stores the private key. Traditional model, suits individual signers who prefer a physical artifact under their control. eSigner for Documents, cloud-based signing with the private key stored in SSL.com's FIPS 140-2 Level 3 cloud HSM. Sign from any internet-connected device via eSigner Express or the CSC API, with no hardware token to carry or manage. eSigner is required for eSealing (automated high-volume signing) and for mobile or travelling signers. Both options produce signatures that verify identically in Adobe Acrobat.

The Adobe Approved Trust List (AATL) is Adobe's root certificate program for document signing CAs. SSL.com is an AATL member, signatures from SSL.com document signing certificates are automatically trusted in Adobe Acrobat, Adobe Reader, and Adobe Sign worldwide with zero recipient-side trust configuration. Without AATL membership, recipients see warning messages about untrusted signers. With AATL, the signature renders as verified on every Adobe product in global use, the practical difference between a signature that works and one that requires every recipient to manually configure trust.

Yes, via eSigner for Documents. Enroll any IV, OV, or IV+OV certificate in eSigner and the private key moves into SSL.com's FIPS 140-2 Level 3 cloud HSM. Sign from laptop, tablet, or phone using eSigner Express (browser-based) or via the CSC (Cloud Signature Consortium) API for developer integration. eSigner also enables eSealing, automated high-volume document signing via CSC API, suitable for batch-signed invoices, automated contract generation, and bulk regulatory filings.
