Third-Party Risk Assessment (TPRA)
Protect what matters with Third-Party Risk Assessment
Your security is only as strong as your weakest vendor. Every supplier with access to your data or systems extends your attack surface, and regulators and enterprise customers increasingly expect you to manage that supply-chain risk formally. Aesparrow builds and runs your third-party risk assessment programme — assessing the vendors that matter, quantifying the risk they carry, and giving you a defensible, repeatable process.
We tier your vendors by criticality and data access, assess their security posture through questionnaires, evidence review and, where warranted, technical validation, and translate the results into a clear risk picture with remediation and contractual recommendations. Whether you need a one-off assessment of a critical supplier or an ongoing TPRM programme, we make third-party risk manageable rather than overwhelming.

Overview
Third-Party Risk Assessment evaluates the security and compliance risk your vendors introduce. We assess and tier suppliers, review their controls and evidence, and deliver a defensible risk picture that supports procurement, compliance and board oversight.
What we assess
- Vendor tiering — criticality and data-access based prioritisation
- Security posture — controls, certifications and evidence review
- Data & privacy handling — how your data is processed and protected
- Fourth-party & concentration risk — sub-processors and dependencies
- Contract & SLA review — security and breach-notification clauses
