Use cases & scenarios

Compromises

  • False positives/negatives leading to misprioritization
  • Uncontrolled tests may cause outages
  • Legal/compliance risks for external tests
  • Regular tests combined with bug bounty programs
  • Automated scans as a precursor to manual tests
  • Clear prioritization by risk and impact

I/O & resources

  • Test scope and permissions
  • Access to target systems or test instances
  • System documentation and architecture overview
  • Detailed test report with priorities
  • Proofs-of-concept and reproduction steps
  • Recommended actions and responsibilities

Description

Penetration testing is a structured security assessment that simulates authorized attacks to identify vulnerabilities in applications, networks, and infrastructure. It combines technical testing, exploit validation, and reporting. Findings are used to prioritize remediation and to strengthen defenses and related processes.

✔

  • Early discovery of technical vulnerabilities
  • Improved incident detection and response
  • Fulfillment of compliance requirements

✖

  • Coverage of unknown attack paths is not guaranteed
  • Result quality depends heavily on tester skills
  • May cause side effects in production

  • Number of critical vulnerabilities found

    Counts vulnerabilities rated critical per test cycle.

  • Time-to-Remediate

    Average time from report to remediation.

  • Reproducibility rate

    Percentage of findings that were reproducibly validated.

Enterprise webshop audit

External pentest identified critical XSS and CSRF issues which were prioritized for remediation.

Infrastructure red team exercise

Simulated attacks revealed insufficient network segmentation and led to architectural changes.

Regular internal pentest

Continuous tests improved detection rules and reduced time-to-detect.

⚠️ Technical debt & bottlenecks

  • Untreated findings accumulate risk
  • Outdated testing tools and signatures
  • Missing automation of regression tests
Limited visibilitySkills shortageFalse positives handling
  • Unauthorized pentests by external providers
  • Ignoring reports due to perceived costs
  • Using invasive exploits during production peak times
  • Confusing vulnerability scans with penetration tests
  • Unclear responsibilities after findings
  • Missing validation of remediations
