OpenSanctions vs Similarweb Digital Data

OpenSanctions provides a structured database of sanctions, politically exposed persons, and other public-interest information assembled from hundreds of sources. It deduplicates entities across sources and models links such as ownership, family ties, political roles, and sanctions designations. The hosted API supports entity matching, full-text search, and full-record retrieval. Its /match endpoint returns ranked candidates for screening details such as names, birth dates, nationality, or tax identifiers. Users can download the full dataset; commercial license customers can run the matching API on their own infrastructure, keeping customer personally identifiable information in their environment. OpenSanctions says data points are traceable to source material and its data pipeline is open source. API access is listed at €0.10 per query, with a 30-day trial; commercial screening and reseller licenses are quoted. The company says it holds ISO 27001:2022 certification and operates under a 99.8% uptime SLA. It supplies data and matching technology, not an end-user compliance application with alert review, case management, and approval workflows. Its data collection is licensed as a complete collection rather than selected parts.
