Web & API Penetration Testing Program

A structured, evidence-based web and API penetration testing program combining manual exploitation, automated validation, CVSS-based reporting, and developer-centric remediation guidance.

Pros

  • Manual validation of complex business logic flaws
  • Strict alignment with OWASP Top 10 and API Security Top 10
  • Deep API authorization and authentication testing (BOLA/BFLA)
  • Business-impact focused reporting with CVSS scoring
  • Streamlined retesting workflow for validated fixes
  • Developer-friendly remediation guidance
  • Detection-aware testing to validate SIEM/SOC visibility

Cons

  • Requires stable staging environment during testing window
  • Heavily dependent on accurate API documentation (OpenAPI/Swagger)
  • Necessitates comprehensive authenticated access and test accounts
  • Potential for limited scope if business context is not fully disclosed

Automated vulnerability scanners are blind to business logic. They can’t chain authorization flaws across multi-tenant systems, and they definitely won’t show your engineers how to fix a tricky Broken Object Level Authorization (BOLA) vulnerability in a production API.

This program is built for engineering teams, SaaS platforms, and enterprises that need hands-on, evidence-based testing aligned with OWASP Web Security Testing Guide and OWASP API Security Top 10 standards. We uncover high-severity issues that automated tools consistently miss, then provide step-by-step reproduction guides and practical fixes your team can actually implement.

Why Detection Matters During Testing

Most pen tests stop at finding the vulnerability. This approach goes further.

Every payload we send is chosen with your defense team in mind. We specifically validate whether your logging infrastructure—whether that’s Cloudflare WAF, AWS CloudTrail, or your internal SIEM—actually detects these attacks. Then we document everything with timestamps and IP addresses so your team can review the evidence after the assessment and refine your detection rules. This turns a penetration test into a real-world validation of your security monitoring.

How We Test

Success starts with clarity on your environments, authentication boundaries, and critical business workflows. Here’s what we focus on:

  1. Reconnaissance & Surface Mapping Find deprecated API versions, forgotten admin panels, and exposed environment variables that might otherwise stay hidden.

  2. Authentication & Authorization Testing Examine OAuth flows, JWT implementation, session generation, and look for privilege escalation opportunities—both horizontal and vertical.

  3. Input Validation & Injection Test for SQL injection, SSRF, XSS, and XXE vulnerabilities with context-aware payloads, not just generic lists.

  4. API-Specific Flaws Hunt for BOLA/IDOR issues, broken function-level authorization, mass assignment, and data exposure across your API surface using your OpenAPI/Swagger documentation.

  5. Business Logic Weaknesses Look for race conditions, state manipulation, and logical bypasses—like manipulating cart totals or skipping payment validation.

We use industry-standard tools like Burp Suite Professional, OWASP ZAP, Postman, Nuclei, and ffuf, plus custom Python and Bash scripts for protocol-specific testing.

What You Get: Clear, Actionable Results

You won’t get a 300-page PDF full of scanner noise. Instead, we deliver findings that your engineering team can immediately act on.

  • Technical Narrative Step-by-step reproduction guides showing exactly how to trigger each vulnerability, with real HTTP requests and responses, plus CVSS v3.1 scoring.

  • Risk Register CSV or Excel format ready to import directly into Jira or ServiceNow so nothing gets lost in translation.

  • Remediation Guide Code examples, OWASP best practices, and CIS Benchmark alignment—so fixes are architecturally sound, not just band-aids.

  • Retest Report After your fixes are deployed, we verify each vulnerability is actually closed and provide signed attestation.

Typical Vulnerability Impact Matrix

SeverityFindingAttack Vector & Business ImpactRemediation Priority
CriticalBOLA / IDORAuthenticated user manipulates tenant_id in API requests to access/modify financial records of other clients.Immediate (0-24h)
HighSQL InjectionLack of parameterized queries on an internal reporting dashboard permits extraction of the user credential table.High (1-3 Days)
MediumMissing Rate LimitingPassword reset endpoint lacks throttling, allowing brute-force token enumeration for account takeover.Medium (1-2 Weeks)

A Typical 30-Day Engagement

  • Days 1-3: Setup and planning Finalize scope, review your API documentation, provision test credentials, and whitelist our testing infrastructure.

  • Days 4-12: Active testing Baseline scans followed by deep manual testing of authentication, authorization, and business logic.

  • Days 13-15: Analysis and reporting Compile evidence, score findings with CVSS, and write up clear technical narratives.

  • Day 16: Debrief and handoff Walk your team through findings and remediation steps.

  • Days 17-30: Your remediation sprint Fix the issues while we validate that the fixes actually work.

The bigger picture: Application security works best when penetration testing feeds directly into your development pipeline. Instead of running compliance-required scans, you get intelligent human testing that tells your engineers exactly where the real risks are and how to fix them properly.
