E-signature without US sub-processors
European e-signature platforms verified to run with no US sub-processors, compared on ownership, hosting region, CLOUD Act exposure, eIDAS level and sub-processor chain.
In short The e-signature platforms listed here operate with no US sub-processors in the data path: an EU/EEA/Switzerland operator with no US parent and no US-incorporated processor handling documents or evidence. No e-signature platform in the directory currently clears that bar. E-signature is a category where Europe holds the structural advantage: a qualified electronic signature legally requires an EU-supervised trust service provider, so the qualified trust layer is European by construction. The harder test is the surrounding stack. Yousign, Universign and Signaturit run document storage, one-time-password SMS or email through US-owned infrastructure such as AWS, Azure, Google, Twilio or SendGrid, and Skribble (Switzerland) names Cloudflare, SparkPost, Chargebee, Userpilot and Clay Labs in its own DPA, which places all of them at CLOUD Act exposure minor or material rather than none. Skribble comes closest: none of its US-incorporated processors touches signed documents. All of them are compared on the main e-signature category page.

About E-signature without US sub-processors
E-signature without US sub-processors, as listed on this page, means the operating company is incorporated in the EU, EEA or Switzerland, holds no US parent in its ownership chain, and routes no document, evidence or signer data through a US-incorporated processor at any point. That covers more than the signature itself: the document storage before and after signing, the audit-trail and evidence layer, the email delivery of signature requests and the identity-verification step all sit in the data path, and all must be clean for the bar to hold.
E-signature is the rare category where European providers hold a structural legal advantage rather than playing catch-up. The eIDAS regulation reserves the qualified signature level (the only one legally equivalent to handwriting across the EU) to trust service providers supervised in a member state, and Switzerland's ZertES framework mirrors this. The test on this page is whether a platform pairs that qualified trust layer with a surrounding stack that is European as well, and on the current check none of them does. We check each vendor's own published documentation and repeat the check every quarter.
Why it matters
Why it matters
The evidentiary chain is what actually gets contested when a signed document ends up in a dispute: not the signature bytes, but the audit trail proving who signed, when, and that the document has not changed since. Building that trail usually calls a time-stamping authority (a TSA) to bind a cryptographic timestamp to the moment of signing, and long-term validation adds periodic re-stamping so the proof survives certificate expiry years later. A platform can run an EU-supervised qualified trust service for the signature itself while the TSA it calls, the document store holding drafts and executions, or the notification email dispatching signature requests sit with a US-incorporated processor, since US jurisdiction reaches any of those regardless of where the platform's own servers are.
The legal asymmetry makes the clean-chain question unusually practical here. Because a qualified signature already forces an EU-supervised trust provider into the stack, a buyer choosing a European platform end-to-end gives up nothing in legal validity: the signed documents carry the same EU-wide effect as those from any US platform reselling the same trust layer, with one less jurisdiction in the timestamping and evidence chain. The directory records the operator, ownership, hosting and full sub-processor list per platform, including who provides the timestamp, so the comparison is between documented chains rather than marketing claims.

This category is on our audit roadmap. Know a fit?
Start from the signature level your documents actually require. Simple and advanced signatures cover most commercial paperwork (NDAs, orders, internal approvals) and every European platform in the category handles them; compare on workflow features, template handling and per-signature pricing. Qualified signatures (QES) are the requirement for documents where law or counterparties demand handwriting-equivalence: certain HR, financial, real-estate and public-sector documents; check each profile for how the QES flow works (video-identification, certificate issuance) and what it costs per signature, since QES pricing differs structurally from simple-signature pricing.
For cross-border Swiss-EU business, dual-framework support (ZertES + eIDAS in one platform) avoids running two tools; Skribble offers both, brokering the qualified layer through Swisscom rather than holding the qualification itself, and its own DPA names US processors, so it does not clear this page's bar. For regulated buyers, read the evidence-retention, timestamping and identity-verification sub-processors in each profile (identity checks are the step where an external provider most often appears) and prefer platforms documenting export-and-delete retention workflows. For SMBs, signer experience and integration with the document tools you already use tend to decide the choice more than the sub-processor chain. Sort or filter the listing above by country, certification or pricing to shorten it.

How we verified every listing here.
For each product we read the public DPA, sub-processors document, hosting region declaration, certifications, and corporate ownership records. Each is timestamped. Signals are editorial, re-verified quarterly. We never accept self-attestation.
