Strong Compliance Based on Long-Term Experience

Timestamp as a Service, the first eIDAS-certified timestamping service based on a qualified timestamp authority since 2001, is creating qualified electronic timestamps for document and data authenticity.


Long-term Evidence of Completion of Time-critical Transactions and Suitable as Piece of Evidence

Timestamp as a Service enables reliable evidence of the completion of time-critical transactions, such as electronic receipt stamps, in automated procurement and tender-ing procedures. The timestamps issued by the Utimaco Time Stamping Authority (TSA) are legally accepted as evidence in court. The re-issuing of personal electronic signa-tures following changes in cryptographic algorithms assures the long-term validity of the generated timestamps.


Full eIDAS-Compliance

Based on the Utimaco TSA, Germany’s first qualified timestamp services according to eIDAS and certified under ETSI EN 319 421 and ETSI EN 319 401, Timestamp as a  Service provides eIDAS-compliant qualified electronic timestamps that can be used throughout Europe and some other countries.



Utimaco’s Timestamp as a Service solution enables eIDAS-compliant proof of time and content, which is of business-critical importance in many fields of application.

Timestamp as a Service generates and validates qualified electronic timestamps required for legally compliant digital business transactions. This solution provides proof that a document has existed unchanged since a spe-cific point in time in a legally compliant manner based on the Utimaco TSA.

The Utimaco TSA and its predecessors are Germany’s first qualified timestamp services according to eIDAS. With Timestamp as a Service, we provide qualified electronic timestamps that can be used throughout Europe and some other countries.
Using Timestamp as a Service provides the advantage of benefitting from our ‘IT Security Made in Germany’ approach, as it is maintained, hosted, and operated in an ISO/IEC 27001, ISO/IEC 27018, and ISO 9001 certified Trust Center in Germany.

Timestamp as a Service has a considerable efficiency advantage over on-premises systems, which allows it to be integrated into existing processes via standard interfaces.

The solution provides large-scale inspections of qualified timestamps through a powerful web service, including online validity checks for included certifi-cates (via OCSP). The multi-language check reports are available in German, English, French, and other languages upon request.
