  • πŸ” Sensitive Data Flow
  • At a Glance πŸ•΅οΈβ€β™‚οΈ
  • πŸ”Ž How Pynt Detects Sensitive Data
  • πŸ† Real-World Example: OWASP crAPI Scan
  • 🎯 Why It Matters
  1. API Security Testing

Sensitive Data Exposure Detection

Detect and prevent sensitive data exposure with Pynt’s AI-powered analysis. Identify PII and data leaks across API environments with automated security testing and flow tracking.

πŸ” Sensitive Data Flow

At a Glance πŸ•΅οΈβ€β™‚οΈ

Pynt automatically detects, tracks, and mitigates sensitive data exposure in APIs by leveraging heuristic analysis, AI-driven pattern recognition, and contextual flow analysis.

πŸš€ Key Capabilities:

  • βœ… AI-powered sensitive data detection (PII, credentials, API keys, etc.)

  • πŸ”— End-to-end data flow tracking to highlight exposure risks

  • πŸ›‘ Automated security testing for improper data leaks

  • πŸ“Š Actionable insights for compliance & security hardening


πŸ”Ž How Pynt Detects Sensitive Data

🧠 1. AI + Heuristics for Detection

Pynt automatically classifies sensitive data during API security scans using: πŸ›  Predefined Heuristics – Recognizing emails, credit card numbers, SSNs, API keys, tokens, etc. πŸ€– AI-Driven Pattern Recognition – Identifying variations of sensitive data that may pose risks. πŸ“‘ Contextual Understanding – Analyzing API requests & responses to detect exposure.

πŸ’‘ Hint: Sensitive data isn't just about what is exposedβ€”it's also about where and how it's used!


πŸ“‘ 2. Mapping Sensitive Data Flows

Beyond detection, Pynt evaluates how sensitive data is processed & transmitted:

πŸ” Traffic Analysis – Monitoring API traffic (live & recorded) for leaks. πŸ›€ End-to-End Flow Tracking – Mapping how sensitive data moves across endpoints. 🚨 Security Tests for Data Leaks – Identifying misconfigurations & access control failures.

πŸ’‘ Hint: API responses sometimes expose more data than needed. Pynt helps reduce exposure proactively! πŸš€


πŸ›  3. Shift-Left: Early Detection in Dev

Pynt integrates into CI/CD pipelines & API testing frameworks to catch data leaks early:

  • πŸ”„ Detects sensitive data exposure in Postman, Newman CLI, Burp, and CI/CD pipelines.

  • πŸ“ Generates detailed reports with exposed data types (PII, HIPAA, PCI, financial data).

  • ⚑ Provides actionable remediation insights for dev & security teams.

πŸ’‘ Hint: Shift-left security means fixing issues before they reach production! πŸ—


πŸ† Real-World Example: OWASP crAPI Scan

πŸ“Œ Case Study: Pynt scanned OWASP crAPI (a vulnerable API application) and found:

πŸ“§ Sensitive data leaks in API responses (emails, full names, VINs). πŸ”“ Endpoints exposing private data due to missing access controls. πŸ“Š Unnecessary data exposure that could be minimized for security.

πŸ”— Example from Pynt Scan Report:


🎯 Why It Matters

πŸ”Ή Protect user data & prevent compliance violations (GDPR, HIPAA, PCI DSS). πŸ”Ή Detect sensitive data leaks before attackers do! πŸ›‘ πŸ”Ή Integrate into your existing security & testing workflows.
