Third-Party Risk Management

Stop inherited risk before it spreads

Third-party vendors are essential — but they’re also one of the most common paths to compromise. NodeZero® helps you move from trust to verification by enabling safe, repeatable penetration testing across your supply chain. With our proven TPRM model, you can validate supplier security without creating overhead, exposing sensitive data, or relying on self-attestations.

A scalable approach to supplier validation

NodeZero makes it easy for suppliers to test themselves — and share results securely. Through a buyer-led program, organizations can initiate targeted tests for their most critical, high-risk, or newly onboarded suppliers. NodeZero autonomously discovers weaknesses, prioritizes real exploitability, and enables instant retesting — no agents, integrations, or red team services required.

Inside the process: how the TPRM model works

Identify and prioritize third parties by risk

Start with your most critical, high-risk, or newly onboarded vendors — the suppliers most likely to impact your business if compromised.

Initiate secure testing without friction

You allocate access, and Horizon3.ai supports the supplier through onboarding, deployment, and test execution.

Run safe, autonomous pentests in production

NodeZero launches safely in minutes — no agents, no creds — and emulates real adversary behavior to surface exploitable weaknesses.

Guide remediation with proof

Each finding includes the affected asset, attack path, and business impact — with instant retesting available to verify fixes.

Track ecosystem resilience

You get centralized dashboards and reporting to track verified fixes and identify systemic issues — without direct access to vendor data.

A proven model — validated by the NSA CAPT program

Horizon3.ai’s TPRM approach is actively used to secure the Defense Industrial Base through the NSA’s CAPT (Continuous Autonomous Penetration Testing) initiative. Hundreds of suppliers across aerospace, defense, and critical infrastructure have validated their security using NodeZero — proving that a buyer-led, autonomous model works at scale. The result: systemic weaknesses are identified and resolved before they become supply chain compromises.

Why suppliers say yes to NodeZero®

Suppliers value NodeZero because it’s fast, safe, and focused on real attacker behavior — not theoretical CVEs or compliance checklists. The biggest benefit? High-quality pentest results and reports can be reused for audits, SOC 2, ISO 27001, CMMC, and other regulatory needs. With detailed reporting and no agent overhead, NodeZero helps them move faster and prove resilience — while reducing the burden of manual questionnaires.

Why this changes how TPRM gets done

You verify supplier security, not just hope for it

Move beyond self-attestations and policy reviews — see what’s actually exploitable in their environment.

You simplify and scale your TPRM program

Initiate tests with no agent installs, no data access headaches, and no manual workflows.

You focus on risk that matters

NodeZero prioritizes attack paths, not scan results — highlighting threats that could impact your business.

You give suppliers security assessments they need

Pentest results support security readiness and compliance — turning risk reduction into shared value.

What security leaders can now prove

We’ve validated our most critical suppliers

NodeZero shows which vendors are truly exploitable — and which have resolved their
weaknesses.

We’ve operationalized vendor assurance

We don’t rely on outdated surveys — we validate with safe, autonomous testing.

We’re reducing inherited risk across our ecosystem

TPRM with NodeZero identifies and contains third-party exposures before they can spread upstream.
