Third-Party Risk Assessment (TPRA)
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.
Third-Party Risk Assessment (TPRA) — done right, the first time.
Senior practitioners. Verified findings. Free re-test.
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
Why choose Aesparrow for TPRA
Risk-based tiering
Focus effort on the vendors that actually carry risk.
Evidence, not just questionnaires
We validate claims, not just collect them.
Actionable output
Clear risk ratings, remediation and contract recommendations.
Programme or point-in-time
A one-off assessment or an ongoing TPRM process.
From onboarding due diligence to continuous monitoring, a structured TPRA programme protects you from risks you do not directly control. Talk to us about assessing your vendor ecosystem.
Frequently Asked Questions
Do you assess our vendors or help us build the programme?+
Both. We can assess specific critical vendors directly, and we can design and operate an ongoing third-party risk management (TPRM) programme for your team to run.
How do you assess a vendor without their full cooperation?+
We combine questionnaires and evidence review with external signals and, where warranted, technical validation. Vendor cooperation improves depth, but we can still provide a meaningful risk view.
Does this help with compliance?+
Yes. Supplier risk management is required or expected by ISO 27001, SOC 2, DPDP, GDPR and many customer contracts, and our output provides the evidence.

Web Application VAPT
Your web application is the front door to your business — and the first thing an attacker probes. Aesparrow’s Web Application VAPT (Vulnerability Assessment and Penetration Testing) combines deep manual testing with trusted tooling to find the flaws that automated scanners miss: broken access control, business-logic abuse, injection, and authentication weaknesses. You get a clear, prioritised picture of what a real attacker could do, and exactly how to fix it before it costs you.
API Security Testing (API VAPT)
APIs power your apps, partners and integrations — and they’re now the most attacked part of most modern platforms. Because APIs expose business logic directly, a single broken authorisation check can leak every customer’s data. Aesparrow’s API Security Testing (API VAPT) is built around the OWASP API Security Top 10 and goes deep on the flaws automated tools consistently miss: broken object-level authorisation (BOLA/IDOR), mass assignment, and business-logic abuse.
Red Team Assessment
A penetration test answers "is this system vulnerable?" A red team assessment answers a harder, more valuable question: "if a determined attacker targeted our business, would we detect and stop them?" Aesparrow’s red team runs a goal-based, adversary-style simulation across people, process and technology — emulating real threat actors to test your detection and response, not just your patch levels.
