Find Vulnerabilities Before Attackers Do
Comprehensive security testing for your APIs. I find authentication flaws, broken access controls, injection vulnerabilities, and business logic issues that automated scanners miss.

// Attacker can forge admin token
}What I Test
Comprehensive coverage across OWASP API Security Top 10 and beyond.
Authentication
- OAuth/OIDC flows
- JWT implementation
- Session management
- MFA bypass attempts
- Password policies
Authorization
- IDOR vulnerabilities
- Privilege escalation
- Function-level access
- Object-level access
- Role bypass
Input Validation
- SQL injection
- NoSQL injection
- Command injection
- XSS vectors
- XXE attacks
Business Logic
- Rate limiting
- Mass assignment
- Race conditions
- Workflow bypass
- Price manipulation
What You Get
Every engagement delivers actionable findings with clear remediation guidance. No vague recommendations—specific fixes you can implement.
Vulnerability Report
Detailed findings with severity ratings, proof-of-concept exploits, and CVSS scores.
Remediation Guide
Code examples and implementation guidance for fixing each vulnerability.
Executive Summary
High-level overview for stakeholders with risk assessment and priorities.
Retest Validation
Verification that fixes are effective once remediation is complete.
Broken Authentication
JWT signature not verified, allowing token forgery
IDOR
User can access other users' data by changing ID parameter
SQL Injection
Search parameter vulnerable to blind SQL injection
Missing Rate Limiting
No rate limiting on login endpoint enables brute force
Verbose Errors
Stack traces exposed in error responses

Scope
Define targets, rules of engagement, and testing constraints.
Discover
Map endpoints, understand authentication, document the attack surface.
Test
Manual testing with automated tool support for comprehensive coverage.
Report
Deliver findings with evidence and remediation guidance.
Common Questions
What types of APIs do you test?
REST, GraphQL, gRPC, and SOAP APIs. Web applications, mobile app backends, and microservices architectures.
Will testing affect my production environment?
Testing can target production, staging, or dedicated test environments. We agree on scope and constraints upfront to avoid disruption.
How do you handle sensitive data during testing?
All testing follows secure handling practices. Findings are encrypted in transit and at rest. Data is deleted after engagement completion.
Do you provide retesting after we fix issues?
Yes, retest validation is included to confirm that vulnerabilities are properly remediated.
