API penetration testing

API Penetration Testing

API penetration testing is a manual security test of your REST or GraphQL APIs. Testers use accounts for each role to check whether the API lets users read or change data they shouldn't, following the OWASP API Security Top 10.

  • Manual, expert-led testing
  • CVSS-rated report with fixes
  • Retest after you fix
  • Written scope before work starts

Requirements Indian businesses usually test for

In India, the trigger for a test is often regulatory. RBI expects regulated entities and their technology vendors to run periodic VAPT. SEBI's cybersecurity framework asks market intermediaries for regular testing. CERT-In directions require organisations to maintain security practices and report incidents. The Digital Personal Data Protection (DPDP) Act 2023 requires reasonable security safeguards for personal data.

Enterprise customers also ask vendors for a recent third-party pentest report during security reviews. We write reports so the same document can be shared with a regulator, an auditor or a customer's security team.

How the engagement runs

  1. 1. Scoping call (30 minutes)

    We agree targets, user roles, environments, testing windows and the compliance reason for the test.

  2. 2. Written scope and quote

    You get a scope document and an INR or USD quote based on the real size of the work.

  3. 3. Discovery and manual testing

    Automated tooling for coverage, then manual testing of authentication, access control and business logic.

  4. 4. Report

    Executive summary, CVSS-rated findings with evidence, reproduction steps and remediation guidance.

  5. 5. Retest

    Once your team ships fixes, we verify each finding and issue an updated report.

What the report contains

  • Executive summary for leadership, customers and auditors
  • Findings rated by CVSS severity with screenshots and request evidence
  • Step-by-step reproduction for your developers
  • Specific remediation guidance, not generic advice
  • Compliance mapping (ISO 27001, SOC 2, PCI DSS, RBI, SEBI, CERT-In guidelines) where relevant
  • Retest status showing which findings are open and closed
