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