Vendor Risk Assessment Software with Nth-Party Visibility
Go beyond direct suppliers. With automated vendor discovery, dynamic vendor mapping, and OSINT-based monitoring, VISO TRUST reveals hidden dependencies, surfaces nth-party risk, and quantifies real vendor dependency risk across your supply chain.

THE CHALLENGE
Blind Spots Beyond Your Third Parties

Hidden fourth-party risk
Most programs track direct vendors but miss who those vendors rely on. Without visibility into third party vs fourth party exposure, high-risk 4th party vendors stay invisible and unaccounted for.
Manual surveys, stale data
Collecting sub-processor lists through questionnaires and spreadsheets is time-consuming and error-prone. Results are outdated as soon as they’re compiled, leaving gaps in fourth-party risk management.

Fragmented signals, little context
Disclosures, trust centers, and public feeds surface data, but rarely in a consistent or relationship-aware way. Teams struggle to connect signals back to the right vendor and assess true vendor dependency risk.
Growing compliance pressure
Frameworks like GDPR, HIPAA, and DORA now expect oversight of downstream providers. Without automated vendor discovery and continuous monitoring, proving due diligence on 3rd party vs 4th party risk is nearly impossible.
THE SOLUTION
Vendor Discovery and Nth-Party Risk with VISO TRUST
VISO TRUST automatically maps vendors of vendors and provides a living view of your extended supply chain.
Automated vendor discovery
Surface sub-processors and downstream providers from disclosures, artifacts, and OSINT—no manual surveys required
Dynamic vendor mapping
Build a living dependency graph that shows shared providers, concentration hotspots, and critical paths
Continuous monitoring
Link OSINT events (breaches, certifications, policy changes) directly to affected vendors and subservices
Evidence-backed reporting
Export dependency maps, narratives, and evidence for boards, regulators, and auditors to prove oversight
The result: practical, audit-ready fourth-party risk management with full visibility across tiers.
What makes VISO TRUST nth-party visibility different

Automatic Vendor Discovery
Manual surveys and spreadsheets leave hidden sub-processors untracked. VISO TRUST automates vendor discovery, surfacing downstream providers without chasing attestations.
- Continuously scan trust centers, disclosures, and uploaded artifacts for sub-processor data
- Parse SOC 2 appendices, ISO docs, and policy pages for buried relationships
- Deduplicate and normalize findings, linking them to legal names and domains
- Update your inventory automatically as vendors add or swap providers
The result? A fresh, accurate catalog of sub-vendors that eliminates manual chasing and gives you a real foundation for fourth-party risk management.
Dependency Graph and Blast Radius
Lists alone don’t show impact. VISO TRUST builds a living vendor mapping graph so you can see how indirect vendors connect to your suppliers.
- Visualize every dependency in a dynamic relationship graph
- Identify where multiple suppliers share the same 4th party vendor
- Highlight concentration hotspots and single points of failure
- Assess blast radius to prioritize remediation and contingency plans
The result? Clear visibility into vendor dependency risk across tiers, helping you understand and act on third-party vs fourth-party exposure.

Continuous Monitoring for Sub-Vendors
Generic feeds flood teams with noise. VISO TRUST applies OSINT monitoring directly to nth-party relationships for actionable alerts.
- Track breaches, expired certs, or policy changes at downstream providers
- Correlate each signal to the right vendor and subservice automatically
- Enrich alerts with impact context and suggested next steps
- Trigger reassessments or vendor evidence requests in a click
Artifact Parsing and Data Normalization
Manual parsing of disclosures is slow and inconsistent. VISO TRUST automates the process to keep evidence usable and defensible.
- Extract sub-processor lists from SOC 2 reports, SIGs, and ISO annexes
- Normalize names, domains, and controls into a consistent format
- Map evidence across multiple frameworks automatically
- Version changes over time to maintain a full audit trail


Shared-Dependency Hotspot Detection
Not all downstream vendors carry equal weight. VISO TRUST highlights the ones that matter most.
- Detect 4th parties supporting multiple critical suppliers
- Quantify exposure by dependency overlap and business criticality
- Segment vendors for targeted due diligence
- Support contingency planning where one dependency represents outsized risk
Evidence-Backed and Traceable
Subjective claims don’t satisfy auditors. VISO TRUST ensures every discovery and signal is verifiable.
- Preserve linked sources, timestamps, and versions for each finding
- Tie alerts back to original disclosures or OSINT references
- Export maps, narratives, and evidence directly for stakeholders
- Maintain a defensible trail of nth-party risk oversight


Integrated Into Your Stack
Risk workflows shouldn’t live in silos. VISO TRUST connects seamlessly with your existing systems.
- Sync alerts and discoveries with ServiceNow, Jira, Archer, and more
- Open tickets and assign owners automatically
- Mirror status changes back to VISO TRUST for consistency
- Keep compliance, risk, and procurement teams working in their systems of record
The result? Faster action, less tool sprawl, and a single source of truth for fourth-party risk management.

Beyond static lists and generic feeds
Tailored
Manual Surveys vs. Automated Vendor Discovery
Competitors rely on annual attestations that go stale the moment they’re submitted. VISO TRUST continuously surfaces nth-party risk from live sources like trust centers, disclosures, and SOC 2 appendices. Findings are deduplicated and normalized, keeping vendor mapping accurate and eliminating survey fatigue.
Traceable
Static Lists vs. Living Dependency Graphs
Point-in-time maps miss how relationships evolve. VISO TRUST builds a dynamic dependency graph that updates automatically as vendors add or change sub-processors. You gain real-time visibility into vendor dependency risk, concentration hotspots, and the true blast radius of third party vs fourth party exposures.
Automated
Generic Alerts vs. Relationship-Aware Insights
Other tools flood teams with headlines that lack context. VISO TRUST correlates every downstream signal to the right direct vendor and subservice, adding relationship detail and data sensitivity. The result: actionable, evidence-backed alerts that help teams reduce fourth party risk and trigger reassessments instantly.
