Lion Cipher Lab

Build a third-party risk management (TPRM) program

Why it matters

Almost every serious breach now has a supply-chain angle: SolarWinds, Log4j, the MOVEit mass-exploitation, the xz-utils backdoor. Your attack surface is no longer just your own systems — it's every vendor with a login, an API key, or a copy of your data, plus their vendors underneath them. You can outsource the work to those vendors, but you can never outsource the accountability: when their breach spills your customers' data, it's your name in the headline and your regulator on the phone. A TPRM program is how a security team stops treating vendors as an afterthought and starts risk-ranking…

What you'll learn

Steps in this lab

  1. What a TPRM program is — and where it sits
  2. Step 1 — Build the inventory (you can't protect what you can't list)
  3. Step 2 — Tier by risk, because you cannot deeply assess everyone
  4. Step 3 — Due diligence: questionnaires, evidence, and when to stop trusting the form
  5. Step 4 — Contractual controls: write the risk into the paper
  6. Step 5 — Continuous monitoring: the part most programs skip
  7. Step 6 — Offboarding: the risk doesn't end when the contract does
  8. The judgment that holds it together — outsource the work, never the risk
