Signatures you can prove.
A signature is only as good as the evidence behind it. Here is how eSignSimple protects your documents and records every step.
Encrypted in transit and at rest
All traffic uses TLS 1.2 or higher. Stored documents are encrypted with AES-256.
Tamper-evident documents
When the last signer finishes, we compute a SHA-256 hash of the final PDF and record it in the certificate. If anyone changes the file afterwards, the hash no longer matches.
Complete audit trail
Each event, from sent and opened to signed and downloaded, is logged with a timestamp, IP address and browser details.
Signer authentication
Signers access documents through unique, expiring links sent to their email. SMS one-time codes are coming soon.
Your files, your control
Delete documents whenever you want. Our free PDF tools run entirely in your browser, so those files never reach our servers.
Privacy by design
We collect only what we need to deliver signatures and keep the audit trail, and we never sell your data.
