AuditSign is a universal verification engine for DocuSign, Adobe Sign, Dropbox Sign, and EU eIDAS certificates. Supports certificate validation across thousands of certificate authorities worldwide. Detect tampering, expired certificates, and untrusted CAs with deep AATL & WebTrust analysis.
AuditSign verifies digital signatures only.
Document content is not read or evaluated.
Most tools tell you whether a signature is valid.
AuditSign tells you whether it is trustworthy.
| Typical Tools | AuditSign |
|---|---|
| Only shows valid / invalid | Explains who issued the certificate and whether the CA is trusted |
| Basic cryptographic checks | Deep trust-chain analysis based on AATL & WebTrust |
| Hard-to-read technical output | Clear visual result + professional downloadable report |
| Single language | Multi-language reports for global use |
AuditSign is a professional digital signature verification platform.
It helps you understand whether a signed document can be trusted — and why — by analyzing signatures, certificates, and their trust sources.
No. AuditSign does not create or apply signatures.
It is designed solely to verify and analyze existing signed documents from platforms such as DocuSign, Adobe Sign, and others.
AuditSign goes beyond basic “valid / invalid” checks.
It analyzes cryptographic integrity, certificate status, issuing authorities, and whether the certificate appears in recognized trust frameworks.
AuditSign evaluates certificates against widely recognized trust frameworks, including:
1. Adobe AATL
2. WebTrust-based CA programs
3. EU eIDAS Trusted List
It also analyzes trust chains against thousands of certificate authorities worldwide.
If a certificate is not found in supported trust lists, AuditSign marks its trust source as unconfirmed.
This means the certificate cannot be verified using publicly recognized trust frameworks.
No. “Not listed” does not necessarily mean the signature is invalid.
It means AuditSign cannot confirm its trustworthiness within known public trust frameworks, and additional local or regulatory context may be required.
No. AuditSign does not read or analyze the document’s textual content.
Only digital signature and certificate metadata are processed for verification purposes.
Yes. AuditSign can generate verification reports in multiple languages, making it suitable for cross-border and international document review.
