Deep API security testing for REST, GraphQL, and backend services
NeedSec tests APIs the way real attackers do — probing for broken authorization, insecure tokens, excessive data exposure, and logic vulnerabilities that automated scanners cannot detect. Every endpoint is tested manually with business context in mind.
Manual-led testing
Every assessment is led by a qualified security engineer — human judgment, not just automated scanning.
Evidence-backed findings
Each vulnerability includes proof of concept, reproduction steps, and a business-impact risk rating.
Actionable fix guidance
Reports are structured for developers and decision makers so remediation can start immediately.
What We Test
Focused testing against realistic attack paths
NeedSec combines manual testing, structured methodology, and business-focused reporting to identify issues that matter — not just scanner noise.
Broken Object Level Authorization (BOLA/IDOR) — cross-user data access
Broken Function Level Authorization — admin endpoint access and role bypass
JWT weakness testing — algorithm confusion, weak secrets, and token forgery
API key and bearer token handling — exposure, reuse, and rotation gaps
GraphQL introspection, batching abuse, and deeply nested query attacks
Mass assignment — unsafe property binding and hidden field manipulation
Excessive data exposure — over-fetching and sensitive field leakage in responses
Rate limiting bypass — brute force, credential stuffing, and abuse prevention
CORS misconfiguration and cross-origin request exploit scenarios
Input validation — injection, type confusion, and parameter tampering
Sensitive data in URLs, logs, headers, and verbose error messages
Business logic chaining — multi-step API abuse and workflow manipulation
