Electronic seal validating a company-issued document

What is an electronic seal?

An electronic seal, or eSeal, is a certificate-backed digital seal linked to a legal entity such as a company, institution, or organization. It helps prove that a document came from the organization, protects the file against later changes, and gives reviewers evidence of origin, authenticity, and integrity.

Protect the origin and integrity of company documents

Add organization-level trust to documents that must be issued, approved, or verified at scale.
