Zero raw data leaves the telco's ecosystem — DDC processes everything behind the firewall while still exposing real-time predictors to the credit engine. Built for credit teams. No paywall, no sales follow-up unless you ask. Download case study The challenge ## Why thin-file customers and data sovereignty had to coexist 01 ### Thin-file users, invisible to bureaus Pre-paid telco users often leave almost no footprint in traditional credit files. Without device-level intelligence, instant credit for them was a non-starter — and rejecting them outright meant leaving millions of customers unmonetised. 02 ### Data must stay home The telco wanted every raw log to remain on infrastructure it already manages — for performance, cost, and audit reasons. Traditional SaaS risk engines, which ship data to third-party systems, were not a viable fit. 03 ### New regulation around data DPDP and DEPA frameworks have raised the bar on data handling. A deployment that keeps all raw signals inside the partner ecosystem is now a regulatory advantage, not just a procurement preference. Get exclusive access — free, no paywall. Download free Outcomes ## What changed after DDC went live Insight 01 ### Data sovereignty without losing intelligence All processing and storage happens entirely within the telco's environment — no external transfers, no third-party storage. Scale and throughput stay firmly under internal control. Insight 02 ### Room for new use cases With raw signals already in-house, the telco's data teams can prototype collections models, cross-sell triggers, and any other analytics project without fresh integrations or new vendor approvals. Insight 03 ### Cost and performance optimisation A configurable infrastructure lets the telco scale usage as and when needed. The choice of involved tools and architecture remains with the telco — FinBox provides the analytics engine, not the deployment opinions. Download the case study — the full version, free. Get the case study How it works ## What FinBox built for the telco A leading Indian telecommunications group wanted to enable instant credit for its millions of customers. The problem: many were thin-file users invisible to bureaus, and the telco wanted every raw log to remain on infrastructure it already manages. Traditional SaaS risk engines that ship data to third-party systems were not a fit. This case study walks through how FinBox's Deployable DeviceConnect (DDC) drops the full device-data intelligence engine inside the telco's private ecosystem — turning SMS contents, app-usage patterns, and device-integrity checks into ready-to-use predictors without exporting raw data. 01 **The data ownership problem**The telco wanted full control over performance, costs, and audits — which meant raw logs had to stay on infrastructure it already managed. SaaS risk engines that route data to third-party systems were ruled out. 02 **Deployable DeviceConnect architecture**DDC ships as containerised services that run inside the telco's own cloud. SMS, app-usage, and device-integrity signals are collected, cleansed, and feature-engineered behind the telco's firewall — predictors are exposed to its decision systems in real time. 03 **Predictor categories**Banking, loan, income-expense profiling, credit-card and investment activity, utility and telco-app footprints, e-wallet patterns, location and device features, anti-fraud signals, propensity, and a custom risk score — all built without exporting raw data. 04 **Compliance built in**All data is anonymised and encrypted in transit and at rest. DDC meets DPDP and DEPA standards, and is stress-tested and independently audited each year. 05 **Self-managed operating model**The telco owns infrastructure setup, application installation, monitoring, and load testing. FinBox owns the analytics engine and core services on the telco's own servers. Tooling and architecture choices stay with the partner. ## Download the case study — free Email it to yourself in under 30 seconds. No paywall, no sales follow-up unless you ask.
