Supply chain assurance

Regulatory frameworks have caught up. Almost every modern compliance regime now pushes security obligations down the supply chain. The principal organisation is expected to demonstrate that its suppliers meet a defined security standard, and that the expectation is being continuously monitored rather than assumed.

Supplier questionnaires are not the answer. A PDF of tick-boxes is not evidence. Supply chain assurance replaces questionnaires with testing.

If you already run a third-party risk management (TPRM) program, this is the testing layer it is missing. The questionnaire records what a supplier believes about their own controls; the test shows what an attacker could actually do in their environment.

Supply chain assurance is a managed program in which NodeZero is run continuously against your nominated suppliers, on a cadence you define, to produce evidence-based assurance that their environments would stand up to a real-world attack.

For you as the principal organisation, that means a current, evidence-backed picture of supply chain risk. For each supplier, you know what is exploitable, what has been remediated, and what remains open. You can demonstrate to your own auditors, regulators, insurers and customers that supply chain risk is being actively managed — not just surveyed.

For each supplier, the program delivers a practical path to improvement. They get a clear, prioritised list of exploitable issues in their environment, remediation guidance, and verification when fixes are applied. For SMEs in the supply chain, that is often the first time they have had a credible view of their own posture. The program turns a compliance obligation into a genuine security uplift.

Scoping. We work with you to define the scope: which suppliers, which tiers, which assets, which cadence, which compliance framework you are aligning to, and what evidence you need produced.

Supplier onboarding. Each supplier is briefed, engaged, and prepared for testing. Consent, scope and scheduling are agreed in writing. Testing is safe for production environments — every exploit NodeZero executes is pre-validated and deterministic.

Continuous testing. NodeZero runs against each supplier’s environment at the agreed cadence. Tests cover internal and external attack surface, identity, cloud infrastructure, and the chained attack paths a real adversary would follow.

Two-sided reporting. You receive a principal-level report aggregating supply chain posture, trend lines, and risk by supplier. Each supplier receives their own remediation-focused report, with verification for fixes.

Remediation and verification. Where suppliers need help closing exploitable paths, we can introduce them to partners who deliver the remediation work. Verification is built in — Quick Verify re-testing confirms closure.

Evidence packs. At audit or assessment time, the evidence required for supply chain security obligations is already prepared — attack-based evidence you can put in front of your auditor or regulator.

The US National Security Agency’s Cybersecurity Collaboration Center runs a program called CAPT — Continuous Autonomous Penetration Testing — which gives US Defence Industrial Base suppliers continuous autonomous offensive testing of their security posture, powered by NodeZero. CAPT is a free government cyber service for defence suppliers, not a commercial offering, but the underlying approach demonstrates what continuous supplier testing at scale looks like in practice.

Supply chain assurance applies the same approach commercially to your supply chain. Whether you are a defence prime managing Tier 2 and Tier 3 suppliers, a financial institution with obligations under prudential regulation, a critical infrastructure operator managing service provider risk, or an enterprise with certification obligations that extend to your vendor base — the underlying problem is the same, and the approach works.

Questionnaires rely on suppliers self-assessing and self-reporting. Every questionnaire answer is a statement by the supplier about themselves. Even honest suppliers are often wrong about their own security posture — the IT team thinks a control is in place, the reality in the environment is different. Dishonest or incompetent suppliers pass questionnaires routinely.

Continuous testing produces evidence, not claims. The evidence is technical, specific, and reproducible. A supplier either has an exploitable path in their environment or they do not. Either the path has been remediated and verified closed, or it has not. Compliance becomes demonstrable rather than asserted.

Principal organisations that carry supply chain security obligations — defence primes, government departments, critical infrastructure operators, financial institutions, healthcare networks, large enterprises with certification requirements.

Suppliers who want to win and retain contracts with organisations that demand evidenced security posture. Participating in a supply chain assurance program — or running NodeZero themselves — becomes a commercial differentiator.

Industry groups and sector bodies looking to uplift supply chain security across their membership. Sector-wide programs aggregate economics, reduce friction for suppliers, and produce aggregated intelligence on sector-level supply chain risk.
