Trusted Signatures - 2026 Pricing, Features, Reviews & Alternatives

Trusted Signatures delivers authentic PDF signatures that display the green checkmark in Adobe Acrobat, providing instant visual proof of document authenticity and integrity. The platform employs a pay-as-you-go pricing model with rates as low as one-hundredth of a cent per signature, eliminating the need for subscriptions or long-term commitments. This cost-effective approach makes enterprise-grade digital signatures accessible for organizations of all sizes, particularly beneficial for legal contracts, regulatory compliance documentation, financial reports, and standard business documents.

The service features a unified interface that supports both Command Line Interface and API integration, enabling seamless automation of the signature process. Trusted Signatures manages certificate security on behalf of users while storing keys in Hardware Security Modules that meet FIPS one hundred forty-three Level three compliance standards. Unlike competitors that retain copies of signed documents, Trusted Signatures never stores client PDFs, ensuring that sensitive information remains exclusively on the client's servers. The platform maintains complete audit trails for all signing activities, supporting compliance requirements across various industries including healthcare.

Trusted Signatures combines bank-level security with operational simplicity through its zero-trust architecture and HIPAA-compliant infrastructure. The system provides managed certificate security that eliminates the technical complexity typically associated with digital signatures while maintaining enterprise-grade protection. This balance of security and usability makes the service appropriate for organizations that require tamper-proof documentation without investing in expensive enterprise solutions or navigating complex technical implementations.
