Advanced Cybersecurity Audit & Targeted Penetration Testing for Complex Systems

In a world of increasingly sophisticated cyber threats, generic vulnerability scans are no longer sufficient.

This service provides a targeted, standards-based penetration testing and cybersecurity audit specifically designed for production-grade systems and enterprise-level applications.

Using a combination of manual exploitation techniques, custom tooling, and methodical auditing frameworks, I help you identify and remediate real security weaknesses — before attackers do.

Scope of Work

1.  Penetration Testing (PT) & Exploitation

• Threat modeling based on your architecture (STRIDE / DREAD model)
• Black-box and grey-box testing approaches
• Manual identification and exploitation of:
  • Input injection flaws (SQLi, XSS, SSTI, RCE)
  • Insecure session/token handling
  • Broken authentication and access control issues (IDOR, privilege escalation)
  • CSRF, SSRF, open redirects, and insecure deserialization

• Lateral movement simulation (internal network only, if access is provided)

2. Infrastructure & Cloud Exposure Testing

• Scanning and validation of exposed services (Nmap, Shodan-like fingerprinting)
• Assessment of firewall policies and ingress rules
• Misconfigured cloud services (e.g., open S3 buckets, overly permissive IAM roles)
• Subdomain enumeration and takeover checks

3.  Application & API Testing

• Deep testing of RESTful and GraphQL APIs
• Header security, rate-limiting, token leakage
• Broken object/property-level authorization
• OAuth/OpenID misconfigurations

4. Compliance-Centric Audit

• Mapping findings to:
  • OWASP Top 10
  • SANS Top 25
  • MITRE ATT&CK framework (when applicable)
  • Regulatory standards (ISO 27001, GDPR, HIPAA, PCI-DSS)

Deliverables

You will receive a detailed technical report covering:

• Executive Summary (risk heatmap + priority matrix)
• Threat modeling diagram (if applicable)
• Vulnerabilities categorized by CVSSv3.1 score
• Exploitable PoCs + reproduction steps
• Clear and actionable remediation instructions
• Mitigation strategy prioritization (Quick wins vs. Long-term hardening)

 Post-Audit Support

• 1x consultation session with your technical team
• 10-day post-delivery window for clarifications or technical Q&A
• Optional retesting after remediation (can be quoted separately)

Toolset

• Burp Suite Pro, OWASP ZAP, Nmap, SQLMap, Gobuster, ffuf, Nikto, Amass, JWT Cracker, custom Python/Go scripts, and more
• Manual testing is always prioritized over automated scanning

Ideal for

• Fintech / SaaS platforms
• E-commerce portals with payment flows
• API-first backends or mobile-integrated systems
• Applications handling sensitive or regulated data
