The short answer: yes! If you...
Subnoto suits teams that want confidential computing , lower cost at scale, and included SSO.
While Yousign offers eIDAS Advanced and Qualified Electronic Signatures for notaries and specific legal transactions, most businesses (95%+) only need simple eIDAS signatures—employment contracts, NDAs, vendor agreements—which both provide. Subnoto adds confidential computing (documents never decrypted server-side), a flat €119/month for unlimited users, and SSO at every tier.
Subnoto focuses on privacy technology and scaling economics; Yousign uses per-user pricing and SSO is a paid option.
