Technical Audit Portfolios

Deep dive reports detailing critical logic bugs discovered during our VAPT audits and secure validation patches implemented for client builds.

FinTech

Prevented BOLA Data Exposure in FinTech API

The Scoping Challenge:

A Neo-Banking Startup was launching their API platform, but security scanning failed to check complex multi-step authorization logic.

Control Gap Analysis:

Identified access boundary vulnerability where row-level queries on transfer endpoints failed to check context tenant ownership.

Calculated Exposure:

Potential leakage of financial records of over 120,000 users, leading to RBI compliance violations and brand loss.

Applied Solution Patch

Implemented resource-level authorization validation filters, cryptographically signed entity IDs, and rate limits.

Audit Metric:120k records secured. Zero data leaks. Completed RBI security audit approval.
Business Impact:98% reduction in unauthorized API calls, achieved ISO 27001 readiness.

HealthTech

Secured HealthTech Patient Portals for Enterprise Integration

The Scoping Challenge:

A fast-growing HealthTech platform failed an enterprise hospital's onboarding assessment due to insufficient HIPAA controls and exposed patient file URLs.

Control Gap Analysis:

Diagnosed exposed storage buckets lacking pre-signed authorization tokens, permitting resource queries on sensitive records.

Calculated Exposure:

Exposed sensitive patient records, threatening massive HIPAA penalties and blocking a $450k annual recurring revenue enterprise deal.

Applied Solution Patch

Migrated files to private buckets with short-lived AWS CloudFront signed cookies and integrated OAuth2 controls.

Audit Metric:SaaS HIPAA compliant in 14 days. Closed the $450k hospital contract.
Business Impact:Passed hospital vendor risk evaluation with 100/100 compliance rating.

SaaS Startup

Audited SaaS Multi-Tenant Architecture on AWS

The Scoping Challenge:

A B2B SaaS tool had complex database queries where tenant filters could be bypassed using SQL structures, resulting in potential cross-tenant leakage.

Control Gap Analysis:

Identified connection pool context overlap inside custom ORM configurations, permitting session telemetry leak across tenancy boundaries.

Calculated Exposure:

Uncontrolled access to company telemetry, dashboards, and client files, which would ruin customer trust.

Applied Solution Patch

Redefined connection pool configuration to apply row-level security (RLS) on PostgreSQL, separating database contexts.

Audit Metric:100% tenant isolation verified. Checked with 15,000 concurrent simulated threads.
Business Impact:Security attestation report delivered to enterprise buyers, reducing sales cycles by 40%.
