ZOREAL Sign

Alternatives to Dropbox Sign

Dropbox Sign, formerly HelloSign, is Dropbox’s e-signature product: a signature request goes out by email, the completed document gets an audit trail cover page with a lookup identifier, and integrity rests on SHA-256 hash records and a hashed transaction log; SMS authentication and European electronic IDs are add-ons on the API plans. ZOREAL Sign is a surface in the ZOREAL dashboard for preparing a signature dossier, sending it through its recipients and recording every step in an append-only event log that is sealed, attested by ZOREAL and timestamped by a public authority. This page sets the two side by side on identity binding, evidence, pricing, integration and certifications.

Information last reviewed 10 September 2026. Compared: the Dropbox Sign web app and the Dropbox Sign API, with the signature allowance inside the Dropbox storage plans, against ZOREAL Sign; Dropbox file storage, DocSend, Dash and Dropbox, Inc.’s company-wide revenue are out of scope.

Where ZOREAL Sign and Dropbox Sign differ

  • Layers of signature

    ZOREAL Sign offers several layers of signature: AES for standard business-to-business contracts, everyday business agreements and non-disclosure agreements, and QES for high-stakes cross-border transactions, regulated corporate and government use, real-estate deeds and formal government filings.

  • Per-user plans on both sides

    Dropbox Sign lists Essentials at $10.05 per month billed annually for one user with unlimited signature requests, and Standard at $17.50 per user per month billed annually with a two-seat minimum (September 2026). ZOREAL Sign: Free for 3 dossiers a month; unlimited dossiers on Premium; 3 dossiers sent per month, unlimited signing of your own documents, and signing a document you receive is always free.

  • Hash records, attested on one side

    Dropbox Sign keeps SHA-256 hash records of the document before and after signing and a hashed transaction log, and states it can provide the two records when tampering has to be disproved; the audit trail page carries an identifier that resolves against Dropbox’s record. ZOREAL Sign ships a detached attestation over the bundle hash, signed ES256 plus ML-DSA-65 under two ZOREAL Document Signing CAs with an RFC 3161 timestamp from a public authority, verifiable offline from the bundle and two pinned roots.

  • European eIDs on the API Premium plan

    Dropbox Sign’s eID add-on, on the API Premium plan and priced by sales, signs through Belgian eID, EvroTrust, Danish MitID, Finnish eID, itsme, Norwegian BankID, SPID, Swedish BankID and Swisscom; SMS authentication is a separate add-on on the API Standard and Premium plans. ZOREAL Sign binds each signature to a legal entity by possession of the invited mailbox, or a ZOREAL account signed in under the invited address, plus the adopted name the person typed.

Side by side

Feature and pricing comparison between ZOREAL Sign and Dropbox Sign, based on public materials reviewed on 10 September 2026.

AttributeZOREAL SignDropbox Sign
CryptographyZOREAL Sign uses post-quantum certificate chains and encryption. Every event (viewed, email confirmed, adopted, signed, approved) is a row with actor, IP address, user agent and both clocks, hash-chained to the previous one, with the original documents’ digests as leaves and a root sealed at Send. When the log closes, the completed PDF is rendered once and stored with its SHA-256, the bundle hash is stamped on every page, and ZOREAL signs a detached attestation (a compact JWS, ES256 plus ML-DSA-65 under the two Document Signing CAs, KMS custody in production) over the bundle hash, the documents’ digests and the stored PDF’s digest, with an RFC 3161 timestamp from a public authority over the ES256 signature. The attestation is verified on every audit-trail print.“Utilizing hashing technology, Dropbox Sign creates a unique record of the underlying document” (legality page); the developer glossary states the audit trail “Includes SHA-256 document hash proving the document wasn’t altered after signing”, and the help centre says the transaction log is processed with hashing technology so that tampering is detectable. A vendor PKI certificate inside the PDF is not described in the public materials we reviewed (legality page, developer glossary, audit trail help page). No post-quantum statement appears on the pages read.
Signer identity, defaultA legal entity per signer, one per email address, born with a P-256 key. A signature is bound to that legal entity by possession of the invited mailbox, or a ZOREAL account signed in under the invited address, plus the adopted name the person typed. The emailed link connects the signing session to the invited mailbox, and the email confirmation is itself an event in the log.An emailed signature request. SMS authentication through the SMS tools add-on on the Standard API and Premium API plans, sold in annual allotments from “$60 for 200 SMS signature requests”; SMS is not supported to signers in the UK. Knowledge-based questions, access codes and government-ID checks are not stated in the public materials we reviewed (pricing pages, SMS add-on page, eID pages).
Signature levelsZOREAL Sign offers several layers of signature: AES for standard business-to-business contracts, everyday business agreements and non-disclosure agreements, and QES for high-stakes cross-border transactions, regulated corporate and government use, real-estate deeds and formal government filings.“Dropbox Sign provides you with a legally binding eSignature solution” (legality page), which states compliance with ESIGN, UETA and “the European Union eIDAS (EU No.910/2014)”; the electronic ID feature page states eIDAS-compliant Advanced and Qualified Electronic Signatures through its eID providers.
Trust behind the top levelZOREAL’s QES has the highest trust in the market, because it requires a government-linked physical ID biologically linked to the person signing.The eID add-on on the API Premium plan, priced by sales, as the help centre lists it: Belgian eID (QES), EvroTrust (QES), Danish MitID (AES through InfoCert), Finnish eID (QES), itsme (QES; Belgium, Luxembourg, Netherlands), Norwegian BankID (AES), SPID (QES), Swedish BankID (AES through InfoCert) and Swisscom (AES, stated as QES under ZertES).
Evidence producedAn append-only, hash-chained event log; the completed PDF stored once with its SHA-256 and the bundle hash on every page; a detached ES256 plus ML-DSA-65 attestation with an RFC 3161 timestamp; an audit-trail PDF; verifiable offline from two pinned roots. The evidence bundle zip holds each burned PDF, Audit trail.pdf, Events.json and Attestation.json, and the attestation is verified on every audit-trail print.“Dropbox Sign affixes an audit trail cover page to the document itself” (legality page), carrying a globally unique identifier that maps to Dropbox’s record; SHA-256 hash records of the document before and after signing, which Dropbox states it can provide when tampering has to be disproved; a hashed transaction log. Self-signed documents do not include an audit trail (help centre).
PricingFree: 3 dossiers sent per month; "Sign your own and received documents for free." Premium: unlimited dossiers sent, private template collections, fillable PDF import. Both plans: 20 documents per dossier ("Up to 64 MB and 100 pages per document"), signer, approver and copy roles, signing order and reminders, the field editor, the public template library, "Typed, drawn and phone QR signatures", "Audit trail, timestamps and evidence bundle", "Signed PDF and completion email".

Premium is priced per user, monthly or yearly, with two months free on yearly billing; every organization member is a paid Premium seat; metered usage is charged separately. Enterprise: contact us. Signing a document you receive is always free. Current prices are on the ZOREAL price list at zoreal.com/pricing.USD, read 10 September 2026: a free plan for signing a document (“Just need to sign a document? Try our free plan”); Essentials “$15 USD/month” monthly or “$10.05 USD/month” billed annually (“$120.60 USD billed yearly”) for one user with unlimited signature requests and 5 templates; Standard “$25 USD/user/month” monthly or “$17.50 USD/user/month” billed annually, “starting at $420 USD billed yearly” for the two-seat minimum; Premium by quote; a 30-day free trial on paid plans. Dropbox’s Plus, Standard and Advanced storage plans include “Signature requests: 3 per month”.
API and integrationsIn the browser, from the ZOREAL dashboard: the editor, the details page, documents by status and templates. An invited recipient opens their own signing link from the email and acts without creating an account; the link connects the signing session to the invited mailbox, and a matching signed-in account is the other way in. Copy recipients receive the finished copy when the dossier is completed.Dropbox Sign API: a free test mode; Essentials API “$75 USD / mo” (“Starting at 50 signature requests/month”); Standard API “$250 USD / mo” with 100 per month; Premium API by quote; SMS tools, electronic ID and premium branding as add-ons, contact sales. The web plans list Google Drive, Microsoft Word and HubSpot integrations on Essentials and Standard, with Salesforce as an additional-cost add-on.
Data handling and retentionWhat a signer enters is saved as they go, locked when they finish and snapshotted onto the audit event. The completed PDF is rendered once when the log closes and stored with its SHA-256. The dossier and its media are retained; a completed dossier is evidence and cannot be destroyed, because its attestation restricts destroy at the model (it is archived instead). The audit trail records the IP address, user agent and both clocks of every event and is printed with the result of a verification run. A retention period is not stated on zoreal.com as of September 2026.The Dropbox trust centre lists Data Retention and Key Management sections whose text did not render in our read; a retention period and key management specifics are not stated in the materials we could read.
Certifications statedOrganization-level, as zoreal.com lists them for Bynn Intelligence, Inc.: SOC 2 (attestation), PCI DSS (SAQ A), GDPR (data protection), ISO/IEC 27001:2022 (information security certification) and CSA STAR Level One (cloud security self-assessment). No signature-scheme certification is claimed for Sign; nothing in the hierarchy is named a qualified signature or seal, and no Sign-specific certification is stated on zoreal.com as of September 2026.SOC 2 Type 2, SOC 3, ISO/IEC 27001, ISO/IEC 27018:2019, HIPAA, HITECH and PCI DSS, with GDPR, CCPA, eIDAS, the ESIGN Act, UETA and the EU-US Data Privacy Framework listed as regulatory items, in the Dropbox trust centre for Dropbox Sign.

Where ZOREAL Sign and Dropbox Sign agree

Both use possession of the invited mailbox as the default attribution: the signature request goes out by email and the person who opens the link is the person the record names. Both keep an audit trail with IP address and timestamps, and both append or ship a human-readable audit record with the completed document, Dropbox Sign as a cover page on the PDF and ZOREAL Sign as the audit-trail PDF in the bundle.

Both prove integrity with SHA-256 hashes and a hash-protected log rather than a certificate embedded in the PDF. Dropbox Sign’s pages describe hash records of the document before and after signing and a hashed transaction log; ZOREAL Sign chains every event to the previous one with the originals’ digests as leaves and stores the completed PDF once with its SHA-256. Neither, in the default product, signs with a key the signer holds.

Both let a person sign a document they receive for free, and both publish a price list with per-user plans. Dropbox’s storage plans include three signature requests a month, the same monthly number as ZOREAL’s free plan gives in dossiers sent. Where the two part is what sits on top: Dropbox Sign’s API plans with a free test mode, its SMS and European eID add-ons, and a trust-centre list that includes SOC 2, ISO 27001, HIPAA and PCI DSS.
