SealDoc Reviews & Product Details

SealDoc turns a document into verifiable evidence. At ingest it is timestamped through a trusted RFC 3161 Time Stamping Authority and written to an append-only, tamper-evident SHA-384 hash chain, so its exact state is fixed and any later change is provable. Everything is stored on immutable WORM storage in an EU datacenter, with no US hyperscaler dependency. Export a Legal Evidence Pack, the record with its event ledger and timestamp, ready for court or audit and independently verifiable by recomputing the hashes from the canonical bytes. SealDoc also handles EU e-invoicing (Factur-X, ZUGFeRD, XRechnung, Peppol BIS 3.0) and archival PDF/A-3. What sets it apart is honesty by design: every guarantee in the pack is asserted only when its proof is present, and timestamp assurance is graded transparently instead of overstated.
