What is Third-Party Risk Management (TPRM)?
Your vendors are part of your attack surface. TPRM is how you manage the risk they carry into your business.
Third-Party Risk Management (TPRM) is the practice of identifying, assessing, and continuously monitoring the security and compliance risk that vendors, suppliers, and partners introduce. If a vendor with access to your data or systems is breached, the impact lands on you and your customers.
A large and growing share of breaches originate through third parties, which is why TPRM has moved from an annual questionnaire exercise to a continuous discipline.
- Any vendor with access to your data, systems, or customers is part of your risk surface.
- Point-in-time questionnaires go stale; continuous monitoring keeps pace with reality.
- The TPRM lifecycle runs from onboarding through offboarding, not just intake.
- Concentration and fourth-party exposure matter as much as individual vendors.
Why vendor risk is your risk
Modern businesses run on dozens or hundreds of SaaS tools, processors, and integrations. Each one that touches your data extends your attack surface. Regulators increasingly expect you to manage that exposure, and enterprise customers ask about it in their own security reviews.
The TPRM lifecycle
Effective TPRM covers the full relationship:
- Onboarding: assess a vendor's security before granting access.
- Tiering: focus effort on the vendors that carry the most risk.
- Continuous monitoring: watch each vendor's external posture over time, not once a year.
- Reassessment: re-check on a risk-based cadence and when something changes.
- Offboarding: remove access and confirm data is handled correctly when a relationship ends.
From questionnaires to continuous signals
Self-reported questionnaires are a snapshot and are easy to game. Pairing them with continuous outside-in monitoring of each vendor's real exposure gives a truer, always-current picture, and flags a vendor whose posture slips after onboarding.
