DPDP Security & Privacy Testing

DPDP Security & Privacy Testing
Our Benefits

Validate Application Security And Privacy Controls

Applications can contain personal-data risks that are not visible during normal functional testing. Security and privacy testing helps identify weaknesses across authentication, authorisation, APIs, data access, application workflows and connected systems.

Personal Data Exposure Testing

Identify situations where personal data may be unnecessarily exposed through application interfaces, APIs, databases, URLs, responses or other application components.

Access Control Validation

Test whether users can access only the information and functionality permitted by their roles and application privileges.

API Security Testing

Assess APIs for excessive data exposure, broken authorisation, insecure endpoints and other weaknesses affecting personal-data protection.

Consent Workflow Testing

Validate whether consent-related application workflows function correctly across expected, unexpected and negative user scenarios.

Data Deletion Testing

Verify whether application deletion workflows operate as intended across relevant databases, files, APIs and connected application components.

Privacy-Focused QA

Include privacy-related scenarios within functional and security testing to identify issues before applications reach production.

Security And QA Expertise For Privacy-Aware Applications

Zillion IT Solutions combines application security, software testing and QA expertise to assess how applications handle personal data across their technical environments. Our testing approach looks beyond conventional functionality to examine whether application controls behave correctly under authorised and unauthorised scenarios. Depending on the application, testing can cover authentication, authorisation, APIs, databases, user workflows, data exposure, logging and third-party integrations. This helps development teams identify technical weaknesses earlier, strengthen application controls and validate changes before deployment. Testing scope can be adapted to the application's architecture, technology stack, data flows and business requirements.

Application Security Testing

Assess applications for technical weaknesses that could expose personal data or allow unintended access to protected functionality.

API Security Assessment

Test APIs for authorisation issues, excessive data exposure, insecure endpoints and weaknesses in data transmission.

Access Control Testing

Validate role-based and user-level permissions to identify unauthorised access to application functionality and information.

Security And QA Expertise For Privacy-Aware Applications
Privacy Workflow Testing

Test consent, preference, account-management and other privacy-related workflows across normal and negative scenarios.

Data Handling Validation

Examine how applications collect, display, transmit, store and delete personal information across relevant technical components.

QA & Regression Testing

Integrate privacy-related test cases into functional and regression testing to ensure changes do not introduce new weaknesses.

Working Process

A Structured Approach To Security And Privacy Testing

We follow a clear, step-by-step process to deliver projects efficiently—from requirement gathering and design to development, deployment, and ongoing support.

Understand Application Architecture

Review application components, technologies, data flows, user roles, APIs and integrations to establish an appropriate testing scope.

Identify Data Flows

Map relevant personal-data paths across frontend interfaces, backend systems, databases, APIs and connected third-party services.

Define Test Scenarios

Develop test cases covering access controls, data exposure, authentication, privacy workflows and application-specific security requirements.

Execute Security Testing

Perform structured testing across application interfaces, APIs, user roles and other relevant technical components.

Validate Findings

Reproduce identified weaknesses, assess their technical impact and work with development teams to understand affected application functionality.

Retest & Report

Validate remediation through retesting and provide clear findings that development and QA teams can use for corrective action.

Services

Comprehensive DPDP Security Testing Capabilities

Zillion IT Solutions provides security and privacy-focused testing across web applications, mobile applications, APIs and connected software environments. Our capabilities can be integrated into application development, QA cycles or assessments of existing software. Testing focuses on identifying technical weaknesses that could result in unauthorised access, unnecessary exposure or incorrect handling of personal data. Depending on the application, we can combine functional testing, security testing and privacy-focused validation to provide development teams with actionable findings and remediation guidance.
