Penetration Testing

Penetration testing is not “run scanners, ship PDF.” We simulate real adversaries: mapping entry points, chaining weaknesses, and proving impact with tight exploit narratives you can actually fix.

What we cover

  • External and internal attack surface discovery

  • Web and API exploitation (including auth and session flows)

  • Credential and secret exposure paths (repos, builds, logs, clients)

  • Privilege escalation and lateral movement opportunities

  • Data access pathways (PII, financial, regulated data)

  • Evidence-grade validation (repro steps + risk story)

Common Failure Modes

Authentication and session breaks

Authentication and session breaks

  • Weak login protections and brute-forceable flows
  • Session fixation, token reuse, and long-lived sessions
  • MFA/OTP logic gaps (bypass, replay, desync)
Authorization and business logic abuse

Authorization and business logic abuse

  • Broken object/property authorization (IDOR/BOLA/BOPLA patterns)
  • Workflow skipping and state machine confusion
  • Abuse of 'support' and 'admin' paths that weren’t meant to be public
Injection and server-side pivots

Injection and server-side pivots

  • SSRF for internal reach and metadata hits
  • Deserialization / template-style injection patterns where applicable
  • Upload / file handling chains that end in data access or execution

Tools and Standards

Core Tooling

  • Burp Suite for hands-on web exploitation and traffic analysis
  • OWASP ZAP for coverage and repeatable scanning
  • Threat modeling alignment to MITRE ATT&CK tactics/techniques
  • OWASP WSTG + ASVS to keep testing systematic

Optional Tooling

  • Targeted fuzzing for high-risk parsers/validators (when applicable)
  • Source-assisted review for critical endpoints and auth gates
  • CI-friendly checks for regression prevention

What we map to

  • OWASP Top 10:2025 (web risk baseline)
  • OWASP API Top 10:2023 (API risk baseline)
  • NIST SSDF for secure development lifecycle

Robots can do audits, but the personal touch makes a difference. That's why we love Immunebytes! Not only do they do top-class audits, but they also take the time to understand our project and why certain things are done in specific ways. They take the time to ensure we feel heard, which shows in their work.

What You Need to Know?

Frequently Asked Questions

We simulate real attacks on your systems to find vulnerabilities before actual attackers do. Think of it as hiring someone to break into your house (legally) to show you where your locks are weak.

Black-box: We know nothing about your system—we attack it like an external hacker would.

White-box: We have full access to your code and architecture—we review everything internally.

Gray-box: We have limited access (like a user account)—simulating an insider or compromised credential scenario.

Most projects benefit from gray-box or white-box because they find deeper issues faster.

The classics still dominate: SQL injection, broken authentication, misconfigured access controls, unpatched dependencies, API authorization gaps, and business logic flaws. The specific mix depends on your stack—web apps fail differently than APIs or desktop software.

Simple web app: 3-5 days

Complex API platform: 1-2 weeks

Enterprise infrastructure: 2-4 weeks

Timeline depends on scope, not calendar—we don't rush findings to hit a deadline.

No. We work in staging environments when possible, and when production testing is required, we coordinate timing and use non-destructive techniques. Any disruptive test gets explicit approval first.

If you handle payment data (PCI-DSS), healthcare info (HIPAA), or customer data in certain jurisdictions (GDPR, SOC 2), yes—regular testing is required. Beyond compliance, it's the cheapest insurance against breaches.
