OneSpan Sign

The signer for regulated industries: deep compliance, strong authentication and serious audit trails.

OneSpan Sign is built for banks, insurers, government and other teams where the audit trail and the identity of the signer matter as much as the signature. It carries SOC 2 Type II, ISO 27001, FedRAMP, HIPAA and eIDAS, layers in strong authentication options, and offers volume based Enterprise pricing for high transaction workflows. The flat Professional plan is a fair $22 a user, but everyday ease of use and the lighter touch features trail the consumer focused signers, which is the expected tradeoff for this depth.
