Four disciplines, one trusted partner.

We connect enterprises that cannot share their data — but still want to create joint value from it. As a fiduciary intermediary we handle matching, pseudonymisation and analysis on your behalf.

01 / Match

DCR Matching

Privacy-preserving matching of datasets inside a closed clean-room environment. Raw data never leaves your premises — we deliver only the result.

  • Hash Match
  • Fuzzy Match
  • Pseudonymisation
02 / Identify

Customer Match

Intersection analyses between your customer base and target lists — for campaign targeting, address hygiene or risk assessments. Fiduciary and audit-ready.

  • Targeting
  • Address Hygiene
  • Reach Estimation
03 / Collaborate

Data Collaboration

Two or more parties contribute data, we orchestrate the exchange inside a defined rule set. You retain ownership and control over your data room.

  • Multi-Party
  • Rule Engine
  • Audit Trail
04 / Analyse

Analytics & Reports

Aggregated insights across combined datasets — from overlap rates and segment profiles to campaign performance, without ever exposing individual records.

  • Overlap
  • Segmentation
  • Attribution
02 · Workflow

How fiduciary data matching works.

Four clearly separated steps. You encrypt, we match, you receive the result — the original data stays exclusively with its respective owners.

STEP 01

Encrypt

Both parties hash their datasets on their own systems using a procedure we provide — plain-text data never leaves the premises.

STEP 02

Transfer

Pseudonymised data is transmitted encrypted into our isolated trusted zone — separated by party, with full audit trail.

STEP 03

Match

Our match engine identifies overlaps and runs agreed analyses on the pseudonymised data — without ever decrypting individual records.

STEP 04

Deliver

You receive aggregated results or an enriched pseudonym set — never the raw data of the other party.

03 · Industries

Eight industries, one pattern.

Three pillars for resilient trust.

Trust comes from architecture — not assurance. Our platform has been optimised for one thing for over a decade: that third-party data cannot, under any circumstance, reach third parties.

Infrastructure

Proprietary, tenant-isolated server architecture in German data centres. Custom-built databases instead of an off-the-shelf cloud stack.

  • Hosting · Germany
  • Physical tenant isolation
  • High-availability & redundant

Cryptography

Hashing procedures, pseudonymisation and encrypted pipelines. Data is never processed in plain text inside the trusted zone.

  • Salted Hashing
  • Transport & At-Rest
  • Key Management

Compliance

Contract data processing under GDPR, contractually secured processes and complete audit trails. We provide the documentation your data-protection team expects.

  • GDPR & BDSG-neu
  • DPA agreements
  • Audit-ready
05 · Company

A small workshop for large questions of trust.

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.
