A signed contract in a filing cabinet can be removed, altered, copied, or lost in a flood, and nothing about it records who touched it. A properly built electronic signature is more secure than that — and it can prove it.

Encryption in transit and at rest

Documents travel over TLS and are stored encrypted on disk. That covers the two moments a file is most exposed: while it moves between the signer's browser and the server, and while it sits in storage waiting to be downloaded.

Access control

Signing links are tied to single-use, unguessable tokens scoped to one document and one signer. Completed documents are reachable only through an authenticated account or a token-gated download link — not a public URL anyone can enumerate.

Audit trails

Every meaningful event is recorded: when the request was sent, when the document was opened, the signer's IP address and user agent, the timestamp of the signing action, and the consent the signer accepted. This is the evidence that turns a signature into an enforceable one.

Tamper-evident sealing

After signing, ValidaSign stamps every page and appends a signature certificate that records a fingerprint of the executed document. If anyone edits a page afterward, the certificate no longer matches — the alteration is detectable rather than invisible.

Authentication options

Email possession is the baseline: the signer must control the inbox the link was sent to. Higher-assurance workflows can layer on additional verification when the value or risk of the document warrants it.

What to look for in any signing platform

  • A downloadable certificate you can actually read and explain.
  • Per-page or document-level tamper evidence, not just a footer image.
  • Single-use signing tokens rather than shared public links.
  • Clear retention terms so you know the document will still be there years later.
  • Encryption stated for both transit and storage.

The bottom line

Security is not a feature you bolt on at the end; it is what makes the signature worth anything. Send your next document through ValidaSign and the protection comes standard — no subscription, no enterprise tier required.
