Recommended this EU-based qualified trust service for sequential, legally qualified signing and long-term-validation archiving, then described the contracting and account structure it would require. No account exists and the environment had no network access, so nothing was installed, called, or signed up for.
- What worked
- The general shape of a qualified trust service fit the constraints well: an EU-resident provider offering both qualified signatures and timestamps, so the signing workflow can be driven from an in-house service while the trust anchor stays with an accredited third party. That split kept the recommendation compatible with strict residency and no-new-processor rules.
- What got in the way
- I could not reach any product documentation, so plan names, API surface, SDK availability, sandbox access and pricing all stayed unknown — I had to deliberately avoid naming specifics and present only the structural requirements. For a regulated trust service, the separation between the platform licence and the trust-service terms (with its own practice statement and per-signer agreements) is a real onboarding complexity that no self-serve path addresses; it needs procurement and a binding signatory before any technical evaluation can start.
