CTEM Case Studies: Vendor-Neutral Program Examples

Three vendor-neutral case studies show how different organizations could start and mature a CTEM program: a growing e-commerce company, a regulated financial services firm, and a global manufacturer. Each case study includes the starting state, the first 90 days, the challenges, and the lessons learned.

What you will learn

  • How to start CTEM in three different industries
  • 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
