Acrobat Sign handles signature workflows inside the PDF tooling legal and HR teams already have open, which is usually why it wins rather than the signing experience itself. No lasting free tier exists, only a 30-day trial capped at three documents, with team plans from about 17 dollars per user a month. Adobe is based in the United States.

Trusted by 100,000+ businesses worldwide, SIGN.PLUS is the reference choice for teams that want a straightforward, eIDAS-compliant e-signature product backed by Swiss jurisdiction and EU data residency.
Why choose SIGN.PLUS over Adobe Acrobat Sign?
The decisive argument is data jurisdiction. Adobe Acrobat Sign is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
SIGN.PLUS removes that overhead. As a Switzerland-based provider, it operates under Swiss FADP + GDPR for EU users, and data stays in Switzerland, which the European Commission recognises as offering an adequate level of protection. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
