API Security for a Leading Life Insurer's Digital Platform

Secured 2,200+ APIs across policy management, agent onboarding, and premium payment systems. Identified critical JWT vulnerabilities and excessive data exposure in customer-facing endpoints.

Key Impact

2,200+ APIs Secured

The Challenge

What They Were Facing

A leading life insurance company had digitized its policy issuance, premium collection, and agent management workflows through 2,200+ APIs. Rapid digitization introduced authentication weaknesses including predictable JWT tokens, missing rate limits on OTP endpoints, and excessive data returned by policy lookup APIs.

JWT token implementation with weak signing keys enabling token forgery.

OTP-based authentication endpoints vulnerable to brute-force attacks.

Policy APIs returning excessive data including nominee PII and bank details.

The Solution

How We Solved It

SecureNexus APIPOS ran a comprehensive API security assessment and deployed continuous monitoring. The platform identified authentication weaknesses, excessive data exposure patterns, and missing rate limiting, then provided remediation guidance aligned with IRDAI data protection requirements.

Auth Assessment

JWT, OAuth, OTP security analysis

Data Exposure Audit

Response payload PII scanning

Rate Limiting

Brute-force protection deployment
