## The panel's verdict

inSign, from inSign GmbH, is a browser-based e-signature product with a distinct API-driven sealing service for company documents. It scores strongest on signature levels, a flat 4, and integration and API, 4 to 6: a REST API drives sealing, and connectors are named for Microsoft SharePoint, Word, Excel, Outlook, SAP, Salesforce and BSI Software. It scores weakest on identity verification, 0 to 2, and pricing transparency, 1 to 2: we found no public information on how signers are authenticated, and while the pricing page states that name-entry and handwritten signatures are included and the qualified signature comes against a surcharge, the captured pages contain no plan prices or surcharge amount, so the cost of a qualified signature is not computable. Signing workflow scores sit at 2, with no public information on templates, signing order or reminders. Sovereignty scores run 4 to 6 on stated German processing — German company, German subcontractors, data centres of German companies, on-premises optional for enterprise — but the trust service provider behind the certificates is unnamed, and external sourcing places the company with the Swiss BSI group.

**Speaks for it:**
- Signing runs in any current browser with no software installation
- A REST API drives the sealing process, with connectors named for Microsoft SharePoint, Word, Excel, Outlook, SAP, Salesforce and BSI Software
- Sealed documents are tamper-evident, with the seal shown in Adobe Reader as a blue bar
- The vendor states it is a German company using German subcontractors, processing data in Germany in data centres of German companies, with on-premises or dedicated hosting optional for enterprise
- A non-binding trial with the full feature set is offered without a credit card

**Held against it:**
- We found no public information on how signers are authenticated for any signature level
- The certificates' issuer is referenced only as an unnamed Trust Service Provider, with no EU Trust List entry linked
- The captured pages contain no plan prices, envelope or document limits, or surcharge amount, so the cost of a qualified signature is not computable
- We found no public information on templates, signing order, reminders or bulk sending of signature requests
- We found no public information on an audit trail, its contents, the timestamp source, or how long signed documents and their evidence are retained

**Best for:**
- You want to seal company documents automatically — the SAP connector automatically seals invoices and returns them to SAP, and the sealing service runs as an automated mass process through the REST API
- Your documents already live in SAP, Salesforce, Microsoft SharePoint or BSI Software and you want signing connected there
- You need a vendor stating German processing — German company, German subcontractors, data centres of German companies — with on-premises or dedicated hosting optional for enterprise
- You sign mostly with name-entry or handwritten biometric signatures, both included

**Avoid if:**
- You must verify who issues the qualified certificates before buying — the captured pages reference only an unnamed Trust Service Provider
- You must budget before committing — the qualified signature comes against a surcharge and the captured pages contain no price figures
- Your compliance review requires documented signer identification — the only method described is the handwritten biometric signature, and we found no public information on identification methods, providers or accepted countries
- You need signed documents and their evidence kept for years — we found no public information on a retention period, and the privacy policy commits to deleting customer data when the relationship ends

## Scores by judge and criterion

### The judges

- **The Legal Counsel** (v1.0): Decides which contracts may be signed electronically and at which level. Wants SES, AdES and QES named per plan and country, the qualified trust service provider linked to the EU Trust List, and an audit trail with timestamps that still validates when the contract is disputed in eight years.
- **The HR Operations Lead** (v1.0): Sends two hundred employment contracts a year, many of them fixed-term and so under written form. Wants QES that a new hire can complete on a phone in ten minutes, identification that accepts the IDs applicants actually hold, bulk sending from templates, and a price per qualified signature known before the contract is signed.
- **The Revenue Operations Lead** (v1.0): Measures how long a quote takes to come back signed and where it stalls. Wants signing from inside the CRM, templates sales cannot break, reminders and signing order that run themselves, and a signer experience that needs no account, no app and no explanation.
- **The Integration Engineer** (v1.0): Embeds signing into the company's own portal and archives the result in the DMS. Wants a versioned API with webhooks and a sandbox, every signature level reachable through the API rather than only in the web app, and signed documents exported with their evidence intact.
- **The Data Protection Officer** (v1.0): Knows every signer who holds an ID card up to a camera hands biometric and identity data to a provider they never chose. Asks who performs the identification, where documents and ID data are stored, how long the audit trail keeps IP addresses, and who the subprocessors in the trust service chain are.
- **The Skeptic** (v1.0): 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.
