VendorTrace.io
Scan your own domain to map every vendor you rely on — or scan a vendor's domain to verify what they actually disclose. Know exactly who processes your data and where, with no questionnaires or vendor cooperation required.
“Your vendor listed 4 sub-processors. We found 23.”
Vendors claim to be compliant, list a handful of subprocessors in their DPA, and promise EU-only data processing. Whether you need to understand your own vendor footprint or verify what a supplier is really running, VendorTrace reveals the full infrastructure reality — passively, objectively, and without asking anyone.
Outside-In Vendor Intelligence
VendorTrace performs passive, objective analysis of publicly observable signals to uncover every third party, geographic data flow, and compliance indicator behind any vendor domain.
Vendor Asset Mapping
Maps the full domain footprint of any vendor using certificate transparency logs and passive DNS — revealing every service and system they operate.
Vendor Deduplication
Detected services are mapped to actual company identities, revealing the full list of third parties — not just what the vendor chose to disclose.
Geographic Intelligence
IP geolocation, ASN analysis, and cloud provider mapping surfaces cross-border data flows and non-EU processing signals for Schrems II assessments.
DNS & Web Crawling
Deep inspection of DNS records, HTTP headers, scripts, trackers, and CSP policies builds a complete, verified infrastructure map.
Compliance Signals
Automatic detection of ISO 27001, SOC 2, and NIS2 certifications, plus GDPR transfer risk indicators — evidence ready for audits.

Timestamped, exportable PDF reports providing defensible evidence for GDPR, NIS2, DORA, and ISO 27001 compliance packages.
