TPRM guides.
Practical guides on third-party risk management — foundational concepts to technical evidence models, written for teams that want to move beyond questionnaire theatre.
Bitemporal Claims: How TrustVendor Models What Vendors Promised and When
TrustVendor uses a bitemporal data model to track both when a vendor made a claim and when we observed it. This distinction is essential for regulatory compliance, dispute resolution, and audit trails.
Evidence Decay: Why Freshness Is a First-Class Risk Concept
A SOC 2 report from eighteen months ago tells you much less than one from last month. Evidence decay is the concept that the assurance value of any piece of evidence decreases over time at a rate that depends on its type. TrustVendor models this explicitly.
Hash-Verifiable Evidence: Making Vendor Claims Auditable
TrustVendor stores a sha256 hash of every document snapshot it processes. This means any claim the system makes can be independently verified against the original source. This guide explains why that matters and how it works.
How to Audit Your Vendors' Subprocessors
Every SaaS vendor uses other vendors to deliver their service. These subprocessors carry your data too. This guide explains how to audit subprocessor lists, what changes to watch for, and how subprocessor monitoring fits into TPRM and GDPR compliance.
Residual Risk in Third-Party Risk Management
Residual risk is the risk that remains after controls are applied. In vendor risk, it is a function of the vendor's security posture, the evidence supporting that posture, and the specific data and systems involved in your relationship. This guide explains how to model it.
SOC 2 Reports Explained: What Compliance Teams Need to Know
A SOC 2 report is the most common security attestation for SaaS vendors, but reading one requires knowing what to look for. This guide explains the structure of a SOC 2 report, what the exception table means, and how to use it in vendor risk decisions.
Vendor Questionnaire Fatigue: Causes, Costs, and Alternatives
Security questionnaires are the dominant tool in third-party risk management, and they are also its biggest problem. This guide examines why questionnaire fatigue exists, what it costs both sides, and what alternatives are replacing manual processes.
What Is Third-Party Risk Management (TPRM)?
Third-party risk management (TPRM) is the process of identifying, assessing, and continuously monitoring the risks posed by vendors, suppliers, and partners. This guide explains what TPRM is, why it matters, and how modern evidence-based approaches differ from traditional questionnaire processes.
