API Security Hardening Engineered to Eliminate BOLA & Endpoint Flaws
APIs power your modern web apps, mobile apps, and enterprise partner integrations—making them the #1 attack vector for modern data breaches. We audit and harden REST, GraphQL, and microservice APIs against the OWASP API Security Top 10.
Traditional Flaws vs. The UraanTech Fix
Why traditional agency engagements stall, leak capital, and deliver brittle solutions.
Broken Object-Level Authorization (BOLA / IDOR)
Endpoints verify user authentication, but fail to check if the user actually owns the requested record ID, exposing entire customer databases.
We enforce centralized authorization middleware and database row-level security ensuring users can only read and write their own records.
GraphQL Depth Overload & DoS Attacks
Malicious actors send deeply nested recursive GraphQL queries that overwhelm backend database CPUs, crashing production services.
We implement query complexity analysis, query depth limiting, and persistent query whitelisting to eliminate resource exhaustion attacks.
Mass Assignment & Parameter Tampering
Endpoints that blindly deserialize JSON payloads allow attackers to elevate their own privileges by adding `"isAdmin": true` to profile updates.
We enforce strict input schema validation (using Pydantic or Zod DTOs) that strips unapproved request properties before processing.
What You Receive
Every deliverable is production-grade, documented, and transferred with 100% intellectual property ownership.
OWASP API Security Top 10 Audit
Comprehensive manual testing targeting BOLA, broken authentication, unrestricted resource consumption, and SSRF.

Real-World Architectural Deployments
Practical use-case breakdowns demonstrating how we engineer solutions around operational bottlenecks.
Neutralizing BOLA Vulnerabilities Across 80 Banking Microservice Endpoints
A neobank had 80 microservice endpoints where changing an account UUID in the request payload returned other users’ confidential banking statements.
- Executed automated and manual fuzzing across all endpoint path and body parameters.
- Engineered a centralized API gateway authorization filter extracting tenant identity from signed JWTs.
- Replaced sequential numeric IDs with cryptographically secure UUIDv4 identifiers across all routes.
- Implemented automated integration tests preventing future PRs from omitting authorization checks.
Eliminating Query Depth Denial-of-Service in Public GraphQL API
An e-commerce analytics platform had their API knocked offline when an attacker submitted a circular 12-layer nested GraphQL query.
- Configured Apollo Server with maximum query depth limits capped at 5 nested levels.
- Implemented query cost analysis assigning point values to database-intensive relational fields.
- Disabled GraphQL introspection schema schema downloads in production environments.
- Deployed Redis-backed rate limiting throttling abuse based on consumed query complexity scores.

Frequently Asked Questions
Broken Object-Level Authorization happens when an API verifies that a user is logged in, but fails to check whether that user has permission to access the specific object requested (e.g. User 5 requests `/api/invoices/99` belonging to User 8). It is the #1 most exploited vulnerability in modern web and mobile backends.
Yes. We specialize in both architectures. For GraphQL, we test for query depth attacks, introspection leakage, field-level authorization bypasses, and batching attacks.
Yes. We deliver automated security regression test suites (in Postman or Playwright) that run in your GitHub Actions or GitLab pipelines to ensure new code commits never re-introduce closed vulnerabilities.
No. Testing is conducted safely on staging environments or dedicated test accounts in production with explicit test tags. We never modify, corrupt, or view real customer records.
A standard API assessment covering up to 40 endpoints typically takes 5 business days of testing, followed by 48 hours for reporting and developer debrief.
