Security you can show your legal team.
Sealwise is built on the same primitives we'd want for our own sensitive contracts: strong cryptography, strict access control, and a complete paper trail.
Encryption in transit & at rest
All documents are protected with TLS 1.3 in transit and AES-256 at rest.
Per-recipient signing tokens
Each signer gets an unguessable link scoped only to their part of the envelope.
Tamper-evident output
Signed PDFs are flattened and stamped with metadata that proves they haven't been altered.
Court-admissible audit trail
Every view, sign, and decline is timestamped and IP-logged on a separate appended page.
ESIGN & UETA aligned
Sealwise envelopes meet the U.S. ESIGN Act and UETA standards for legally binding e-signatures.
Isolated tenant data
Row-level security means a customer can never read another customer's envelopes — by construction.
