Independent penetration test for TISAX

The situation

A tubular metals manufacturer supplying automotive customers was in the final stage of a TISAX Level 3 assessment.

It needed a penetration test from a party independent of the provider that runs its network. Testing your own managed environment does not satisfy the separation of duties the standard expects.

How we scoped it

  • External testing of a VPN-only perimeter across two states
  • Internal testing of about 200 hosts across seven network segments and three sites, including directory services
  • One internal web application and a light-touch cloud identity review
  • A 100-user phishing exercise, excluding shared mailboxes
  • Production equipment observed passively only, so the plant floor is never put at risk
  • Testing scheduled over a plant shutdown weekend to avoid production impact
  • A full paperwork set: statement of work, mutual NDA, authorization letter and rules of engagement

What a buyer in this position should ask any provider

  1. Are you independent of our managed service provider?
  2. How do you treat operational technology?
  3. When do you test relative to our production schedule?
