Privacy-preserving matching of datasets inside a closed clean-room environment. Raw data never leaves your premises — we deliver only the result.
Intersection analyses between your customer base and target lists — for campaign targeting, address hygiene or risk assessments. Fiduciary and audit-ready.
Two or more parties contribute data, we orchestrate the exchange inside a defined rule set. You retain ownership and control over your data room.
Aggregated insights across combined datasets — from overlap rates and segment profiles to campaign performance, without ever exposing individual records.
Both parties hash their datasets on their own systems using a procedure we provide — plain-text data never leaves the premises.
Pseudonymised data is transmitted encrypted into our isolated trusted zone — separated by party, with full audit trail.
Our match engine identifies overlaps and runs agreed analyses on the pseudonymised data — without ever decrypting individual records.
You receive aggregated results or an enriched pseudonym set — never the raw data of the other party.
Proprietary, tenant-isolated server architecture in German data centres. Custom-built databases instead of an off-the-shelf cloud stack.
Hashing procedures, pseudonymisation and encrypted pipelines. Data is never processed in plain text inside the trusted zone.
Contract data processing under GDPR, contractually secured processes and complete audit trails. We provide the documentation your data-protection team expects.
SDW IT-Services has been active since 2010 as a specialised service provider for fiduciary data management. We don't build a generic platform — we look after each project individually, with our own code, our own systems and dedicated points of contact.
Personal commitment, intensive identification with your product and an open, fair client relationship are our differentiators. Our clients stay.
A call or an e-mail is enough for a first conversation. NDA in place before any detailed exchange — naturally.
