What Is a UIDAI AUA/KUA Audit?
A UIDAI AUA/KUA audit is a mandatory annual security and compliance audit for entities that use Aadhaar authentication or eKYC services. The audit validates that AUA, KUA, Sub-AUA, and Sub-KUA entities comply with UIDAI's data security requirements, covering Aadhaar data handling, encryption, storage, access controls, and application security.
Who Needs a UIDAI AUA/KUA Audit?
Any entity in the Aadhaar authentication and eKYC ecosystem must undergo an annual compliance audit and share the report with UIDAI.
Authentication User Agency (AUA)
Entities that use Aadhaar authentication to verify identity via UIDAI services. Audit covers authentication request flows, biometric/OTP/demographic handling, encryption, device security, logs, and API integration.
eKYC User Agency (KUA)
Entities authorized to receive eKYC data from UIDAI. Audit adds stronger review of eKYC data handling, storage, masking, retention, access control, sharing, deletion, and privacy controls.
Sub-AUA
Downstream entities using Aadhaar authentication through a parent AUA. Audit emphasizes parent oversight, contract controls, application and data-flow review, vendor controls, and annual compliance evidence.
Sub-KUA
Downstream entities using eKYC services through a parent KUA. Audit scope includes all Sub-AUA requirements plus eKYC data handling, retention, deletion, and privacy controls.
Banks and NBFCs Using Aadhaar eKYC
Financial institutions leveraging Aadhaar for customer onboarding, KYC verification, loan processing, or account opening through licensed AUA/KUA partners.
Fintech and Payment Companies
Payment aggregators, wallets, lending platforms, and fintechs using Aadhaar-based authentication or eKYC for customer identity verification and onboarding.
Government and Public Sector Entities
Government departments, PSUs, and public-facing platforms using Aadhaar for citizen identity verification, DBT, and service delivery.
Telecom and Insurance Companies
Telecom operators using Aadhaar eKYC for SIM activation and insurance companies using Aadhaar for policyholder verification and claims processing.
Methodology
7 stages. Audit-ready results.
Every engagement follows this process through Lemon, our proprietary audit management platform.
Security Brigade's UIDAI audit methodology goes beyond checklist completion. Our auditors validate actual Aadhaar authentication and eKYC application flows, test encryption implementations, review Aadhaar Vault architecture, and verify data handling practices through evidence and technical testing. A control is considered compliant only when policies, procedures, mechanisms, resources, and technical enablements are actually in place for ongoing compliance.
Scoping and Architecture Review
Document AUA/KUA/Sub-AUA/Sub-KUA role, Aadhaar integration architecture, ASA connectivity, application landscape, and all systems touching Aadhaar data. Collect authorization agreements and prior audit reports.
Data-Flow and Encryption Validation
Map Aadhaar data flows across application, network, API, ASA, storage, logs, support, and reporting systems. Validate encryption-at-source, encryption-in-transit, Aadhaar Vault or reference-key architecture, and HSM key management controls.
Application and Device Security Testing
Test Aadhaar authentication and eKYC applications through VAPT, SAST, and DAST. Review biometric device and registered-device (RD) controls. Validate OTP, biometric, demographic, and eKYC flow integrity.
Access Control and Audit Trail Review
Review access control matrices, privileged access management, maker-checker controls, admin logging, audit trail completeness, log retention, monitoring, and incident response readiness.
Data Retention, Deletion, and Masking Review
Validate masked Aadhaar usage, storage minimization, Aadhaar number and VID and UID token handling, eKYC XML/PDF data management, data retention schedules, and deletion controls.
Gap Assessment and Remediation Support
Deliver risk-ranked gap report with specific observations and remediation guidance. Work with your engineering and compliance teams to close non-compliances before the final report.
Final Report and UIDAI Submission Pack
Issue the final UIDAI AUA/KUA Compliance Audit Report with the completed UIDAI checklist including compliance status, auditor observations, and management comments. Prepare the submission-ready pack for UIDAI.
"We needed an assessment on a 3-week timeline because of a partner integration deadline. Security Brigade turned it around in 18 days, including the L2 and L3 reviews. The report was regulator-ready — we submitted it to our partner's compliance team unchanged. When speed and credibility both matter, they're the only call we make."

Quality Assurance
Multi-Tier Review: L1/L2/L3 Audit Quality Assurance
Every UIDAI audit report passes through a rigorous multi-tier review before it reaches you or UIDAI.
Security Brigade's multi-tier review process ensures that no checklist item is marked compliant without verified evidence, no non-compliance is missed due to auditor oversight, and every observation is technically accurate and clearly documented. This process is enforced through Lemon and cannot be bypassed. No audit report is released without manager sign-off and clearance of all platform-generated quality alerts.
L1: Auditor Execution
The assigned auditor conducts the full technical assessment, collects evidence, validates controls, and documents findings against the UIDAI checklist.
L2: Manager Review
A senior manager reviews every checklist item, validates evidence sufficiency, checks for missing test cases, and ensures observation quality and consistency.
L3: Lead Approval
The engagement lead performs final quality review, validates report accuracy, ensures UIDAI submission readiness, and signs off on the audit report before release.
