NPCI and UPI Security and Compliance Audit

Trusted by India's leading enterprises
Assess
We map your UPI infrastructure, payment data flows, and integrations against NPCI requirements. Role-specific scope is defined based on whether you are a PSP, TPAP, sponsor bank, BBPOU, or RuPay participant. Every application, API, backend system, and data storage location is catalogued.
Remediate
Findings are risk-ranked with practical remediation guidance tailored to your engineering and operations teams. Our consultants work directly with your CTO, DevOps, and security teams to close gaps. Lemon tracks every finding from identification through evidence-backed closure.
Certify
Once all findings are closed, we issue the final compliance report with no open findings, ready for submission to NPCI. The report includes executive summaries for your CISO and compliance leadership, technical annexures, and the closure validation pack that NPCI expects.
What is an NPCI/UPI Security and Compliance Audit?
An NPCI/UPI Security and Compliance Audit is a mandatory annual assessment of payment infrastructure, applications, APIs, and data handling practices for entities participating in the NPCI ecosystem including UPI, BBPS, and RuPay.
Who Needs an NPCI/UPI Security Audit?
The audit applies to every entity in the NPCI payment ecosystem, with role-specific scope requirements
PSP Banks (Payment Service Providers)
Bank-side UPI infrastructure, NPCI connectivity, UPI switch integration, transaction processing, fraud monitoring, uptime, reconciliation, dispute handling, and TPAP oversight.
TPAPs (Third-Party Application Providers)
Mobile app, backend, APIs, SDK integration, device binding, VPA/account linking, customer data handling, authentication, encryption, and India-only data storage.
Sponsor Banks
Governance over TPAP or fintech partners, contract controls, compliance oversight, data flows, audit rights, operational resilience, and incident escalation.
BBPS / BBPOU Participants
Biller and agent onboarding, BBPCU/BBPOU integration, payment and settlement flows, refunds and disputes, biller APIs, reconciliation, and customer complaint handling.
RuPay Participants
Card issuance and acquiring flows, cardholder data environment, POS/e-commerce/ATM transaction flows, EMV and contactless security, fraud monitoring, and chargeback/dispute handling.
UPI Feature-Specific Entities
Entities offering UPI 2.0 signed intent, UPI AutoPay/e-mandate, Credit on UPI, International UPI, or merchant QR flows require feature-specific add-on scope beyond the core audit.
Methodology
6 steps. Zero guesswork.
Every engagement follows this process through Lemon, our proprietary audit management platform.
Scoping and Role Mapping
Define your NPCI ecosystem role (PSP, TPAP, sponsor bank, BBPOU, RuPay). Map applicable UPI features (AutoPay, Credit on UPI, International UPI, merchant QR). Identify all in-scope applications, APIs, infrastructure, databases, cloud regions, and third-party integrations.
Architecture and Data Flow Review
Review application architecture, UPI integration design, PSP-bank connectivity, device binding mechanisms, and VPA/account linking flows. Map complete UPI transaction data flows from frontend through backend, APIs, databases, logs, backups, and third-party processors. Validate India-only data storage at every layer.
Security Testing and Technical Validation
Application and API security testing using B-52. Mobile app testing for UPI apps including SDK integration, device binding, session controls, and authentication. Backend and infrastructure assessment. Network segmentation verification. Encryption validation in transit and at rest. Cloud configuration review for data localization evidence.
NPCI Control Mapping and Gap Assessment
Map every finding and observation against the NPCI/UPI checklist and role-specific requirements. Produce a gap assessment with risk-ranked findings, evidence gaps, and recommended remediation. Cover fraud monitoring, reconciliation, dispute handling, incident response, and SDLC controls.
Remediation Support and Closure Validation
Work directly with your CTO, DevOps, security engineering, and compliance teams to close findings. Lemon tracks every finding with owner, severity, target closure date, and validation evidence. Revalidation testing confirms each fix is effective. No finding is marked closed without evidence.
Final Compliance Report Submission
Issue the final NPCI/UPI Security Audit Report with no open findings. Includes role-specific checklist mapping, technical annexures, data localization evidence, executive summary for CISO and compliance leadership, and the closure validation pack. Report is structured for direct submission to NPCI.
"Security Brigade's structured approach through Lemon gave us complete visibility into the testing process. The three-layer review caught issues that our previous vendor missed entirely. Their reports were the first our developers could actually act on without a follow-up call."
