Read this page as one judge. Each weighs the same scores by what they care about.

The Skeptic

Weighted verdict

Knows "legally binding" usually means a simple signature. Reads for the level the default plan actually signs at, the QTSP the provider does not operate itself, the per-QES and ident fees on top of the plan, the envelope limit, and "eIDAS-compliant" from a provider that names no trust service at all.

Same scores as the panel view — this lens weights them the way this judge cares.

eIDAS levels & trust services

How this is scored

Which signature levels the platform offers — simple, advanced, qualified, and qualified seals — through which qualified trust service provider on the EU Trust List, for which countries and legal regimes (eIDAS, ZertES), and on which plans.

0 — No signature level named; the platform calls its signature "legally binding" without saying which kind it is.

3 — Simple signatures by default with "advanced" or "qualified" mentioned as available, but no trust service provider named and no statement on which plan or country offers which level.

5 — SES, AdES and QES offered and labelled in the product, the qualified trust service provider named, and which documents need which level explained for at least Germany or the EU.

8 — Every level documented with the plans and countries it is available in, the QTSP's entry on the EU Trust List linked, QES under eIDAS (and ZertES where relevant) stated, qualified electronic seals for company documents, and the signature level printed in the signed document and audit trail.

10 — Levels are an explicit product decision: the provider is or contracts a named QTSP with its conformity assessment published, level selection per document type or template, remote QES without a separate account, EUDI wallet support stated with a date, and the legal effect per level documented for the main EU markets.

Report an error

The Skeptic

The captured developer pages never label a signature level for the signing product — no simple, advanced or qualified tier, no plan or country mapping — and the compliance pitch rests on a generic claim of e-signature law compliance in the US, Europe, Japan and elsewhere. The only qualified trust services in evidence are timestamps and a separate PDF sealing API routed through named third parties such as Intesi Group and TrustPro, with no EU Trust List entry shown. 1 6

Signer identification

How this is scored

How the signer is identified for each level: email and SMS codes, video ident, eID card (Online-Ausweis), bank ident or EUDI wallet — who performs it, in which countries it works, and what happens to the ID data afterwards.

0 — Email link only; no statement on how signers are authenticated.

3 — Email plus SMS or access code, with "ID verification" mentioned as an add-on but no methods, provider or countries named.

5 — Identification methods for AdES and QES listed by name (for example video ident, eID, bank ident), the identification provider named, and the countries or ID documents they accept stated.

8 — Methods documented per level and country, automated and agent-based ident distinguished, reuse of an identification for later signatures explained, retention and deletion of ID data stated, and the ident provider listed as subprocessor.

10 — Identification is transparent end to end: every method with its countries, assurance level and failure rate or completion guidance, EUDI wallet and national eID supported, ID data minimisation and retention committed, and the signer-facing privacy notice published.

Report an error

The Skeptic

We found no public information on how signers are identified or authenticated for any level — no email or SMS codes, no video or bank ident, no eID, no provider, no countries, nothing on retention of ID data. The only signer-facing statement is that recipients sign on any desktop or device without downloads or accounts. 6

Signing workflow & signer experience

How this is scored

Getting a document out and back signed: templates and form fields, signing order and roles, bulk sending, reminders and delegation, signing without an account or app, mobile signing, and accessibility for signers.

0 — Single-recipient signing of an uploaded PDF; no templates, order or reminders.

3 — Multiple signers and basic templates, but no signing order, no bulk send, and signers must create an account.

5 — Templates with field placement, sequential and parallel signing order, automatic reminders and expiry, signing without an account on mobile, and a status overview for the sender.

8 — Roles and conditional fields, bulk sending, delegation and substitute signers, team and approval workflows, branded signer experience, signer languages listed, and signer accessibility addressed.

10 — The workflow is complete and documented: web forms and self-service signing links, mixed signature levels within one process, in-person and remote signing, a published accessibility conformance statement, and team administration with shared templates and audit of sender actions.

Report an error

The Skeptic

The documented story is sending a document out for signature, account-free signing on any device, tracking status and storing the approved document — that is the whole of it. We found no public information on templates and field placement, signing order, bulk sending, reminders, delegation or signer accessibility in the captured material. 6

Report an error

Evidence, validation & retention

How this is scored

What proves a signature years later: the audit trail and certificate of completion, qualified timestamps, long-term validation (PAdES-LTV), validation reports, and how long signed documents and evidence are kept — and whether they can leave the platform.

0 — A signed PDF and nothing else; no audit trail, no statement on storage or deletion.

3 — An audit trail or completion certificate exists, but its contents, the timestamp source and the retention period are unstated.

5 — Audit trail with signer events, IP addresses and authentication method embedded in or attached to the signed PDF, timestamps applied, documents downloadable, and the retention period stated.

8 — PAdES signatures with long-term validation, qualified timestamps from a named provider, a validation tool or report, configurable retention and automatic deletion, and bulk export of documents with their evidence.

10 — Evidence outlives the subscription: LTV and archive timestamps documented, validation verifiable with independent tools such as the EU DSS validator, export to a DMS or archive with evidence intact, and post-termination access and deletion committed in the terms.

Report an error

The Skeptic

Timestamps come from named providers including Adobe Qualified Timestamp, InfoCert Qualified TSA and Namirial Qualified TSA, tampering after sealing is detectable, and the seal can be verified in Adobe Acrobat — that part is real, though it belongs to the sealing API. We found no public information on the audit trail's contents, long-term validation, or any retention period, and "securely store approved documents" is the entirety of the storage statement. 1 2 3 6

Integrations & API

How this is scored

Signing from inside the systems where contracts are made: a documented API with webhooks and a sandbox, embedded signing, and connectors for Microsoft 365, CRM, HR, DMS and ERP systems.

0 — No API and no integrations; everything happens in the vendor's web app.

3 — A few named integrations or a Zapier connector, and an API mentioned without public documentation.

5 — A documented REST API with webhooks and a sandbox, plus connectors for Microsoft 365 or Google Workspace and at least one CRM or HR system named.

8 — Embedded signing in the customer's own application, API access to every signature level, versioned API with rate limits published, SDKs, and connectors for named DMS, ERP or HR systems with their scope.

10 — Integration is a product: white-label and embedded flows documented, API parity with the web app, a status page with incident history, deprecation policy, and a marketplace of integrations with stated maintainers.

Report an error

The Skeptic

This is where the effort visibly went: a documented REST API, webhooks with OAuth2.0 spelled out endpoint by endpoint, ready-to-run samples for Node.js, Java,.NET and Python, embedded e-signature for apps and platforms, and an OEM/Embedded partner track with private APIs. We found no public information on a sandbox, published rate limits, API versioning or a single named Microsoft 365, CRM, HR or DMS connector in the captured pages. 2 5 6

European sovereignty

How this is scored

Who the contracting entity, the trust service provider and their owners are, where documents, audit trails and ID data are stored and processed, and who the subprocessors are. Independently sourced by the sovereignty pipeline.

0 — Non-EU contracting entity, no statement on where documents and signer data are stored, and subprocessors unnamed.

3 — An EU entity contracts, but documents or signer data are processed outside the EU by default without an explained safeguard, or the subprocessor list is absent.

5 — EU contracting entity and EU data storage stated, with a DPA, but the hosting, identification or trust service chain is non-EU-controlled without a stated safeguard.

8 — EU entity, documents, audit trails and ID data stored in named EU data centres, an EU qualified trust service provider, subprocessor list with locations published, and certifications (ISO 27001, ETSI conformity) published.

10 — Sovereign end to end and evidenced: European ownership, EU entity and EU QTSP, every processing location and subprocessor European, customer-selectable data residency, and certifications with their scope published.

Report an error

The Skeptic

EU customers contract with Adobe Systems Software Ireland Limited, but the parent is Adobe Inc. of San Jose, and we found no public information on where documents, audit trails and signer data are stored, on any subprocessor list with locations, or on published certifications beyond a security overview document. Every named trust service provider is a third party; the hosting and identification chain is invisible in the captured pages. 1 6

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a buyer can compute the cost of their signing volume from public pages alone — plan prices, envelope or document limits, the per-signature price of AdES and QES, identification fees, API pricing and overage.

0 — No public prices at all; every plan is a sales conversation.

3 — Plan prices published, but envelope limits, QES and identification fees are unstated — the cost of a qualified signature is unknowable.

5 — Plans with envelope or document limits priced, but at least one commonly incurred cost (per-QES fee, video ident, API access, overage) is missing or "on request".

8 — Every plan and limit priced publicly, AdES and QES priced per signature, identification fees and overage stated, API pricing published, and contract term and notice period given.

10 — Complete cost computability: the cost of a given monthly volume per signature level derivable from public pages, volume tiers published, and every add-on and price-change term on a public page.

Report an error

The Skeptic

Not one price appears in the captured material — no plan prices, no envelope limits, no per-signature or per-seal fee, no identification fee, no API pricing, no overage, no contract term. A buyer cannot compute any part of their signing cost from these pages; every number is a conversation with sales. 6
