- How scope choices differ by business model
- What to expect in the first 90 days
Explanation
Case 1 — E-commerce (Series B, 300 people)
Starting state: a scanner and a cloud posture tool, no shared prioritization. First scope: checkout. First month: exposure register, top-ten list, one attack path validated (leaked API key). Lesson: business owner engagement was the biggest unlock.
Case 2 — Regional bank (5,000 people)
Starting state: heavy compliance program, thousands of CVEs open. First scope: internet banking. First month: aligned CTEM output with regulatory reporting; introduced attack-path context. Lesson: connect CTEM metrics to existing risk committees, do not create parallel reporting.
Case 3 — Global manufacturer (30,000 people)
Starting state: IT/OT split, weak identity data. First scope: plant-floor identity risks. First month: discovery joined with EDR and IAM data; three privilege paths closed. Lesson: in OT-heavy environments, start with identity, not patching.
How to apply this
- Match your context to the closest case
- Adopt one specific pattern from that case
- Track your own case study for internal sharing
Common mistakes
- Copying scope from a case study that does not match your business model
- Ignoring identity-heavy patterns in favor of scan-heavy patterns
- Assuming case study timelines apply to your organization
