About TimestampCompare
TimestampCompare is an independent benchmark project helping B2B buyers, CTOs, compliance officers, and legal teams evaluate timestamping providers with transparent, evidence-based scoring.
Research scope
We track timestamping authorities globally, from major enterprise providers to regional specialists and community projects, covering both eIDAS-qualified and non-qualified services.
Scoring model
Weighted across 5 categories: Security & Compliance (37%), Expertise & Focus (20%), API & Developer (18%), Features & Usability (17%), and Pricing (8%). Dynamic weighting on the scoring page lets you reprioritize.
Update cadence
We refresh benchmark inputs quarterly and re-score providers whenever material service changes are confirmed by vendor announcements or trust list updates.
Neutrality pledge
TimestampCompare does not accept paid placements, affiliate commissions, or sponsored content. Rankings reflect independently verified criteria only.
Key timestamping features compared
Each feature is scored based on publicly available information — provider websites, documentation, and certification pages. Where data is not disclosed, the criterion is left unscored rather than guessed. Use the free buyer checklist below to ask providers directly about any undisclosed points.
Security & Compliance
37% of the score. Covers eIDAS qualification, ISO 27001, archive timestamping, sealing capability, and eIDAS qualification seniority.
API & Developer Experience
20% of the score. Evaluated on API availability, sandbox environment, developer documentation quality, public status monitoring and recent outage history.
Pricing & Commercial
20% of the score. Assesses recurring maintenance fees and setup costs (inverted: lower fees = better score). Negative review rates are informational.
Features & Usability
20% of the score. Reviews admin interface availability, manual timestamping capability and AI readiness.
Expertise & Focus
20% of the score. The sole weighted criterion is an identified operational team. Primary focus, published timestamping articles and eIDAS qualification year are informational only.
