The IT/OT Pen Test Greatest Hits Why Your Findings Report Looks Like on Repeat

The talk argues that penetration testing reports—especially in IT/OT environments—keep surfacing the same issues over and over, which signals deeper systemic problems rather than isolated vulnerabilities.

Key takeaways

  • “Same findings, different day” problem
    Pen test reports are repetitive because organizations aren’t fixing root causes—just patching symptoms.
  • Common recurring issues
    • Weak or reused credentials
    • Poor network segmentation (especially IT ↔ OT bleed)
    • Excessive privileges and lack of least-privilege controls
    • Outdated systems that can’t easily be secured
    • Misconfigurations that persist across environments
  • OT makes everything worse
    • Legacy systems + uptime requirements = security tradeoffs
    • Flat networks and remote access paths create easy attack routes
    • Visibility is limited, so issues linger undetected
  • The real problem isn’t technical—it’s operational
    • Security findings don’t get prioritized or owned
    • Teams lack alignment between IT, OT, and leadership
    • Risk is accepted implicitly rather than consciously
  • Reports aren’t driving change
    • Pen test outputs often become checkbox exercises
    • Without accountability and follow-through, nothing improves
