Diagram patterns, jurisdiction mapping and retention overlays. By Hemant Attri , Founder, Attri Edge · July 17, 2026 · Updated July 17, 2026 · 2 min read Auditors and enterprise buyers increasingly ask: “Show me where customer data flows.” The answer needs to be a clear diagram, not a verbal explanation. For US SaaS with India operations, the cross-border data-flow diagram is a core artifact, part of the DPDPA + framework-mapping pillar. What data flow diagrams accomplish A good diagram answers, in one view: what data exists, where it’s collected, where it’s processed and stored, who (and which systems) touch it and where it crosses the US-India boundary. It turns the riskiest question in a review into a confident, visual answer. The diagram pattern Map data categories as they move: client → US application tier → datastores → India engineering access (via VDI/managed channels) → sub-processors. Show the systems, not just the boxes and mark every point where data crosses jurisdictions. Tie each node back to your data inventory from the cross-mapping playbook . Jurisdiction layer Overlay jurisdiction: which nodes are in the US, which in India and where personal data of Indian residents lives or is accessed. This layer is what DPDPA reviewers and US buyers most want to see, and it surfaces any sectoral localization (RBI payment data, etc.) you must honor. Retention layer Annotate each datastore with its retention period and disposal mechanism. Retention is both a SOC 2 and a DPDPA control; showing it on the diagram links the flow to your retention schedule. Encryption and security layer Mark encryption in transit and at rest, key management and the access controls at each boundary, especially how India engineering reaches production (VDI, conditional access) per the SOC 2 India cornerstone . Tools for diagram creation Lucidchart, draw.io , Excalidraw or Miro all work. Keep the source versioned alongside your compliance docs, and publish a sanitized version to your trust center. Where Attri Edge fits Building and maintaining the cross-border data-flow diagram, kept accurate and tied to the data inventory, is part of the Active Retainer. The diagnostic flags whether your current documentation will satisfy a cross-border review.

Not strictly mandated by the Trust Services Criteria, but auditors and buyers increasingly request data-flow documentation, especially for cross-border operations. For US-India teams it's effectively expected, and it strengthens both SOC 2 and DPDPA evidence. Tool recommendations? Any clear diagramming tool, Lucidchart, draw.io, Excalidraw, Miro. The tool matters less than keeping the diagram accurate, versioned and tied to your data inventory. Update frequency? Review at least quarterly and on any architecture or sub-processor change. A stale data-flow diagram is worse than none, buyers and auditors will catch the mismatch with reality. Sharing externally, safe or risk? Share a sanitized version (no secrets, no internal hostnames) under NDA via your trust center. It answers the 'where does our data go?' question proactively and shortens reviews.
