Fourth-Party Risk Management: Seeing the Vendors Behind Your Vendors

You may know your vendors.

But do you know your vendors’ vendors?

A SaaS provider relies on a cloud platform.
A payroll provider uses a subcontracted support center.
A customer support platform uses an AI model provider.
A payment processor depends on downstream processors and banking infrastructure.
A healthcare business associate uses subprocessors.
A managed service provider uses remote access tooling.
A data analytics vendor uses cloud storage, data enrichment providers, and offshore support.
A critical software vendor relies on an open-source component, hosting provider, and identity vendor.
A vendor’s vendor has an incident, but your organization feels the impact.

That is fourth-party risk.

Third-party risk management traditionally focuses on the direct vendor relationship.

But modern business services are delivered through ecosystems.

The direct vendor may not own the infrastructure.
The direct vendor may not process all data itself.
The direct vendor may not provide the AI model.
The direct vendor may not perform all support activities.
The direct vendor may not control every location where services are performed.
The direct vendor may not be the only party that can create operational, cyber, privacy, regulatory, or resilience risk.

That creates hard questions:

• Who are the vendors behind our vendors?

• Which ones process our data?

• Which ones support critical services?

• Which ones provide cloud, AI, security, payment, support, analytics, or infrastructure services?

• Which ones have access to systems or confidential information?

• Which ones are concentrated across many vendors?

• Which ones are involved in incidents?

• Which ones must be disclosed to customers, regulators, or contract partners?

• Which ones require evidence?

• Which ones create risk that should be escalated?

Fourth-party risk management is how organizations answer those questions.

In Connected GRC, fourth-party risk is not a side note in a vendor questionnaire.

It is a connected operating model that links vendors, subcontractors, subprocessors, model providers, data, systems, services, contracts, evidence, incidents, issues, risk acceptance, and dashboards.

The goal is simple:

See the dependency chain before the dependency chain becomes the incident.

What is fourth-party risk management?

Fourth-party risk management is the process of identifying, assessing, monitoring, evidencing, and governing the subcontractors, subprocessors, model providers, suppliers, cloud providers, service providers, and other downstream parties that support your direct vendors.

Fourth-party risk may involve:

• cyber risk

• privacy risk

• operational resilience risk

• concentration risk

• subcontractor risk

• subprocessor risk

• cloud-provider dependency

• AI model-provider dependency

• data processing risk

• geographic or jurisdictional risk

• business continuity risk

• incident response risk

• contract flow-down risk

• audit and evidence risk

• regulatory reporting risk

• customer assurance risk

A weak fourth-party model says:

“Our vendor manages its vendors.”

A stronger model says:

“Our vendor manages its vendors, but we know which fourth parties support critical services, process sensitive data, provide key infrastructure, create concentration risk, or require escalation, evidence, or contractual controls.”

That is the difference.

Fourth-party risk does not mean you directly manage every subcontractor.

It means you know enough about the downstream dependency chain to manage your own risk.

Fourth party vs third party vs subprocessor vs subcontractor

These terms overlap, but they are not identical.

A fourth party may be a subprocessor.

A subprocessor may be a fourth party.

A model provider may also be a subprocessor if it processes personal data.

A cloud provider may be both a critical fourth party and a concentration dependency.

The classification matters because different review, contract, evidence, and monitoring expectations may apply.

Why fourth-party risk matters

Fourth-party risk matters because organizations increasingly rely on vendors that rely on other providers.

Your direct vendor may be well managed.

But your exposure may still depend on:

• the vendor’s cloud provider

• the vendor’s data center

• the vendor’s AI model provider

• the vendor’s offshore support provider

• the vendor’s subcontracted implementation partner

• the vendor’s payment processor

• the vendor’s identity provider

• the vendor’s managed security provider

• the vendor’s analytics provider

• the vendor’s open-source supply chain

• the vendor’s fourth-party incident response capabilities

A fourth party can create risk in several ways:

• It processes your data.

• It stores your data.

• It has access to systems.

• It provides infrastructure.

• It supports a critical service.

• It affects service availability.

• It affects incident response.

• It creates geographic or transfer risk.

• It weakens contract commitments.

• It creates concentration risk across many vendors.

• It becomes the source of an incident.

NIST’s C-SCRM quick-start guide describes a broad supply-chain ecosystem involving suppliers, developers, system integrators, external service providers, and technology-related service providers. That is the practical reality fourth-party risk management addresses.

The Fourth-Party Risk Management Model

A practical fourth-party risk model has 12 stages:

1. Identify where fourth parties exist.

2. Build the fourth-party inventory.

3. Classify fourth parties by risk and criticality.

4. Map fourth parties to vendors, services, systems, data, and regions.

5. Review contract and flow-down obligations.

6. Assess privacy, subprocessor, and data risk.

7. Assess cyber, technology, and access risk.

8. Assess operational resilience and concentration risk.

9. Collect evidence and assurance.

10. Monitor changes, incidents, and performance.

11. Track issues, exceptions, and risk acceptance.

12. Report fourth-party risk in dashboards.

The workflow should be risk-based.

Not every fourth party needs deep review.

But fourth parties that process sensitive data, support critical services, provide key infrastructure, create concentration exposure, or participate in high-risk AI or cyber workflows need visibility.

1. Identify Where Fourth Parties Exist

Fourth-party risk starts with discovery.

Common fourth-party sources include:

• vendor questionnaires

• security assessments

• privacy reviews

• data processing agreements

• subprocessor lists

• SOC reports

• ISO certificates

• contract exhibits

• vendor architecture diagrams

• vendor incident reports

• vendor business continuity plans

• AI model-provider disclosures

• implementation partner lists

• vendor support documentation

• procurement records

• cloud dependency records

• open-source and software composition data

• customer assurance artifacts

• regulatory or audit requests

Ask direct vendors:

• Do you use subcontractors?

• Do you use subprocessors?

• Do you use cloud providers?

• Do you use offshore support?

• Do you use model providers or AI providers?

• Do any downstream providers process our data?

• Do any downstream providers support critical services?

• Do any downstream providers have system access?

• Do you notify us of changes?

• Can we object to certain changes?

• Do contract obligations flow down?

• What evidence is available?

Do not rely only on a one-time questionnaire.

Fourth-party relationships change.

Subprocessors are added.
Cloud regions change.
Model providers change.
Support providers change.
Subcontractors change.
Data processing locations change.

Discovery should be ongoing.

Fourth-party discovery checklist

2. Build the Fourth-Party Inventory

Fourth-party risk cannot be managed from scattered lists.

Create a fourth-party inventory.

Each fourth-party record should include:

• fourth-party name

• direct vendor

• type of fourth party

• service provided

• data processed

• system access

• location

• cloud region or data center, where relevant

• criticality

• concentration exposure

• contract flow-down status

• evidence available

• incidents

• issues

• monitoring status

• approval or objection status

• risk acceptance status

• dashboard status

The fourth-party inventory should not become a massive unmanaged database.

Start with fourth parties that matter most:

• subprocessors processing personal data

• cloud providers supporting critical vendors

• model providers supporting AI vendors

• subcontractors supporting critical services

• providers with access to sensitive systems

• common dependencies across many vendors

• subcontractors involved in incidents

• fourth parties in high-risk geographies

• fourth parties supporting regulated workflows

The inventory should link to the direct vendor.

The organization may not have a contract with the fourth party, but it still needs to know which direct vendor depends on it.

Fourth-party inventory checklist

3. Classify Fourth Parties by Risk and Criticality

Not all fourth parties are equal.

Risk classification should consider:

• service criticality

• data sensitivity

• system access

• customer impact

• operational dependency

• regulatory relevance

• geography

• subcontractor depth

• concentration risk

• incident history

• substitutability

• evidence availability

• direct vendor oversight quality

A practical model:

The 2023 interagency guidance states that third-party risk management should be tailored based on risk and criticality, with more rigorous oversight for higher-risk activities, including critical activities. That principle applies well to fourth-party risk.

A fourth party behind a low-risk vendor may need minimal tracking.

A fourth party behind a critical service or sensitive data flow may require evidence, change notification, issue tracking, and escalation.

Fourth-party classification checklist

4. Map Fourth Parties to Vendors, Services, Systems, Data, and Regions

Fourth-party risk becomes actionable when it is mapped.

A fourth party should link to:

• direct vendor

• business service

• critical service

• product

• business process

• system

• data category

• data location

• country or region

• contract

• obligation

• control

• evidence

• incident

• issue

• risk acceptance

• dashboard

Example:

A customer support SaaS vendor uses:

• a cloud provider

• an AI model provider

• an offshore support subcontractor

• a logging platform

• an email delivery provider

That single vendor relationship may create several fourth-party dependencies.

Each dependency affects different risk questions:

• Cloud provider: availability, resilience, concentration, data location.

• AI model provider: data use, training, prompts, outputs, monitoring.

• Offshore support subcontractor: access, confidentiality, privacy, location.

• Logging platform: sensitive logs, retention, incident evidence.

• Email provider: customer communication, deliverability, data exposure.

The direct vendor record should not simply say “subprocessors disclosed.”

It should connect each relevant fourth party to the data, services, systems, and risks it affects.

Fourth-party mapping checklist

5. Review Contract and Flow-Down Obligations

Fourth-party risk is often governed through the direct vendor contract.

Key contract questions include:

• Is subcontracting allowed?

• Is subprocessing allowed?

• Is approval required?

• Is notice required before changes?

• Can the organization object?

• Are data protection obligations flowed down?

• Are confidentiality obligations flowed down?

• Are security requirements flowed down?

• Are incident notification obligations flowed down?

• Are audit and assurance obligations flowed down?

• Are retention and deletion obligations flowed down?

• Are business continuity obligations flowed down?

• Are location restrictions flowed down?

• Are AI data-use restrictions flowed down?

• Are subcontractors required to meet equivalent controls?

• Is the direct vendor liable for subcontractor performance?

GDPR Article 28 requires that where a processor engages another processor, the same data protection obligations from the controller-processor contract are imposed on the other processor. ICO guidance explains that the controller-processor contract should address prior authorization for subprocessors, notice of intended subprocessor changes, and equivalent flow-down obligations.

Contract flow-down matters because the organization may not directly contract with the fourth party.

The direct vendor must be responsible for the downstream obligations.

If the contract does not address fourth parties, the organization may have weak leverage when risk appears.

Contract flow-down checklist

6. Assess Privacy, Subprocessor, and Data Risk

Fourth parties often matter most when they process data.

Privacy review should ask:

• Does the fourth party process personal data?

• Does it process sensitive personal data?

• Does it process customer data?

• Does it process employee data?

• Does it process regulated data?

• Does it store or access logs?

• Does it process AI prompts or outputs?

• Where is the data processed?

• Are cross-border transfers involved?

• Is the fourth party listed as a subprocessor?

• Is subprocessor authorization required?

• Are data deletion and return obligations flowed down?

• Are breach notification obligations flowed down?

• Is evidence available?

• Does the data inventory need updating?

Privacy risk is not limited to the direct vendor.

A direct vendor may have strong controls, but a subprocessor may process data in a different geography, support a different retention model, or have different incident notification timing.

A fourth party can also affect data subject rights, deletion, breach assessment, and customer assurance.

For AI vendors, a model provider may process prompts and outputs.

That model provider may be a fourth party, a subprocessor, and a critical AI dependency at the same time.

Fourth-party privacy checklist

7. Assess Cyber, Technology, and Access Risk

Fourth parties can create cyber risk through infrastructure, support access, software, APIs, integrations, and supply-chain dependencies.

Cyber review should ask:

• Does the fourth party host the service?

• Does it provide cloud infrastructure?

• Does it provide identity, logging, monitoring, or security services?

• Does it have access to systems?

• Does it have access to data?

• Does it provide remote support?

• Does it manage code, updates, or deployments?

• Does it provide an AI model or API?

• Does it have incident notification obligations?

• Does it maintain security certifications or reports?

• Are vulnerabilities or cyber incidents known?

• Does the direct vendor monitor fourth-party cyber posture?

• Is fourth-party evidence available?

NIST’s C-SCRM guidance is relevant because supply-chain risk includes technology-related providers involved in developing, integrating, operating, maintaining, and managing systems and services.

Fourth-party cyber risk is especially important where:

• a vendor supports critical services

• data is sensitive

• the fourth party provides core infrastructure

• the fourth party is widely used across many vendors

• the fourth party has privileged access

• the fourth party participates in software updates

• the fourth party supports AI or automation

• the fourth party has a history of incidents

Cyber teams should not be expected to review every fourth party deeply.

But they should be able to see which fourth parties matter.

Fourth-party cyber checklist

8. Assess Operational Resilience and Concentration Risk

Fourth-party risk often becomes visible during outages.

A direct vendor may fail because its cloud provider fails.

Multiple vendors may fail at the same time because they rely on the same cloud region, identity platform, payment processor, AI model provider, DNS provider, or data center.

This is concentration risk.

Ask:

• Which fourth parties support critical services?

• Which fourth parties are used by multiple direct vendors?

• Which fourth parties support multiple business units?

• Which fourth parties support regulated or customer-facing services?

• Which cloud providers, regions, or data centers are concentrated?

• Which model providers are used across AI tools?

• Which processors or infrastructure providers support multiple payment flows?

• Which identity providers support multiple vendors?

• Which fourth parties have no practical substitute?

• Which fourth-party outage scenarios have been tested?

EIOPA explains that DORA’s oversight framework for critical ICT third-party providers helps address potential systemic and concentration risks from the financial sector’s reliance on a limited number of ICT providers. That is a useful concept for any organization with vendor concentration.

Operational resilience should connect fourth parties to:

• critical services

• business impact

• continuity plans

• recovery objectives

• exit strategies

• vendor alternatives

• incident history

• test results

• risk acceptance

• dashboards

A fourth party may not process data but still create resilience risk.

For example, a DNS provider or cloud identity provider may not be a privacy risk, but it may be critical to availability.

Concentration and resilience checklist

9. Collect Evidence and Assurance

Fourth-party evidence is harder than direct vendor evidence because the organization often lacks a direct relationship.

Evidence may come through the direct vendor.

Possible evidence includes:

• subprocessor list

• subcontractor list

• vendor due diligence summary

• flow-down contract attestation

• security certifications

• SOC report

• ISO certificate

• penetration test summary

• privacy assessment

• data processing agreement

• business continuity summary

• incident response summary

• AI model provider documentation

• cloud provider assurance report

• subcontractor audit summary

• concentration-risk assessment

• fourth-party monitoring report

• direct vendor attestation

The evidence question is not always:

“Can we audit the fourth party?”

Often the practical question is:

“Can the direct vendor prove that it governs the fourth party appropriately?”

For high-risk fourth parties, ask:

• What due diligence did the direct vendor perform?

• What ongoing monitoring does the direct vendor perform?

• What contract obligations flow down?

• What evidence is available?

• How are incidents reported?

• How are changes notified?

• How are issues remediated?

• Can we obtain assurance if needed?

Evidence should be linked to the fourth-party record or direct vendor record.

Do not leave it buried in questionnaire responses.

Fourth-party evidence checklist

10. Monitor Changes, Incidents, and Performance

Fourth-party risk changes over time.

Monitor:

• new subprocessors

• new subcontractors

• model provider changes

• cloud provider or region changes

• service location changes

• data processing location changes

• fourth-party incidents

• direct vendor incident reports

• direct vendor evidence refresh

• concentration-risk changes

• criticality changes

• data scope changes

• contract changes

• exit strategy changes

• regulatory changes

Monitoring should be risk-based.

Low-risk fourth parties may be reviewed during periodic vendor reassessment.

Critical fourth parties may need:

• change notification

• direct vendor attestations

• evidence refresh

• incident escalation

• dashboard reporting

• executive review

• concentration-risk monitoring

The EBA’s DORA subcontracting RTS explicitly emphasizes implementation, monitoring, and management of contractual subcontracting arrangements so financial entities can monitor the entire ICT subcontracting chain for critical or important functions. Even when DORA does not apply, this is a strong operating principle.

Fourth-party monitoring should not rely only on annual questionnaires.

Changes can create immediate risk.

Fourth-party monitoring checklist

11. Track Issues, Exceptions, and Risk Acceptance

Fourth-party gaps should not remain in vendor notes.

Create issues for:

• missing subprocessor disclosure

• missing subcontractor list

• missing model provider disclosure

• unclear data processing location

• missing flow-down terms

• weak incident notification terms

• insufficient fourth-party evidence

• fourth-party security concern

• fourth-party privacy concern

• fourth-party concentration risk

• unsupported critical dependency

• direct vendor cannot monitor subcontractor

• subprocessor change without notice

• model provider change without review

• fourth-party incident not reported timely

Each issue should include:

• affected direct vendor

• affected fourth party

• affected data

• affected service

• affected contract

• owner

• severity

• root cause

• remediation plan

• evidence required

• validation method

• residual risk

• risk acceptance, if needed

• dashboard status

Sometimes the organization cannot eliminate fourth-party risk immediately.

Risk acceptance may be needed when:

• direct vendor cannot provide full evidence

• a critical fourth party cannot be replaced

• concentration risk cannot be reduced quickly

• subprocessor terms are being remediated

• data location risk requires phased mitigation

• monitoring is incomplete but compensating controls exist

• a business unit needs the vendor to continue temporarily

Risk acceptance should be documented, approved, time-bound, monitored, and visible.

It should not be hidden in a vendor review comment.

Fourth-party issue checklist

12. Report Fourth-Party Risk in Dashboards

Fourth-party risk should appear in dashboards.

Useful views include:

• vendors with disclosed fourth parties

• vendors missing fourth-party disclosures

• critical vendors with fourth-party dependencies

• fourth parties supporting critical services

• fourth parties processing sensitive data

• fourth parties by region or data location

• fourth parties with system access

• fourth parties supporting AI use cases

• model providers behind AI vendors

• most common fourth parties across vendors

• concentration dependencies

• fourth-party incidents

• fourth-party evidence gaps

• fourth-party issues overdue

• fourth-party risk acceptances

• fourth-party changes pending review

• decisions needed

The dashboard should help leaders see dependencies that are otherwise hidden.

It should answer:

• Which fourth parties matter most?

• Where do we have concentration risk?

• Which fourth parties process sensitive data?

• Which vendors cannot disclose or govern their fourth parties?

• Which fourth-party issues are open?

• Which accepted risks need review?

Dashboards should not overwhelm leaders with every subcontractor.

They should highlight fourth parties that create meaningful exposure.

Fourth-Party Risk Examples

Example 1: SaaS vendor using a cloud provider

A customer data platform uses a major cloud provider.

Fourth-party risk questions:

• Which cloud regions are used?

• Where is customer data stored?

• Does the contract require location notice?

• Does the cloud provider support resilience expectations?

• Does the SaaS vendor have business continuity plans?

• Are cloud-provider incidents included in vendor incident reporting?

• Is there concentration across several vendors using the same cloud provider?

Possible control:

Critical SaaS vendors must disclose cloud hosting providers and regions, provide evidence of cloud resilience controls, and notify the organization of material hosting changes.

Example 2: AI vendor using a model provider

An AI-enabled customer support vendor uses an external model provider.

Fourth-party risk questions:

• Does the model provider receive prompts?

• Does the model provider receive outputs?

• Can the model provider use data for training?

• Are prompts or outputs retained?

• Is the model provider a subprocessor?

• Are model provider changes notified?

• Is monitoring available?

• Are AI incidents reported?

Possible control:

AI vendors must disclose model providers, prompt/output retention, training rights, subprocessors, and model-provider change notification terms before approval.

Example 3: Payroll vendor using offshore support

A payroll vendor uses a subcontracted offshore support center.

Fourth-party risk questions:

• Does the subcontractor access employee data?

• Is confidentiality flowed down?

• Are access controls documented?

• Is location disclosed?

• Are breach notification obligations flowed down?

• Are support sessions logged?

• Is data transfer reviewed?

• Can the organization object to changes?

Possible control:

Vendors processing employee data must disclose support subcontractors with data access and provide evidence of confidentiality, access control, and security obligations.

Example 4: Critical vendor using subcontracted implementation partner

A critical operational vendor uses a subcontracted implementation partner during rollout.

Fourth-party risk questions:

• Does the subcontractor access production systems?

• Is access time-bound?

• Are credentials managed?

• Are subcontractor personnel screened?

• Is the subcontractor covered by security obligations?

• Who validates access removal after implementation?

Possible control:

Implementation subcontractors with production access must be identified, approved, time-bound, and offboarded with evidence after the project.

Example 5: Multiple vendors rely on the same provider

Several critical vendors rely on the same cloud provider, identity provider, payment processor, or AI model provider.

Fourth-party risk questions:

• Which critical services depend on the same fourth party?

• What outage scenario could affect multiple vendors simultaneously?

• Are alternate providers available?

• Are continuity plans tested?

• Is this concentration risk accepted?

• Should executives review the dependency?

Possible control:

Fourth-party concentration dependencies are reviewed quarterly for critical services and escalated when one downstream provider supports multiple high-criticality vendors.

Fourth-Party Risk Dashboard

A fourth-party risk dashboard should show:

The dashboard should be risk-weighted.

A list of every fourth party is less useful than a focused view of fourth parties that matter.

Fourth-Party Risk Metrics

Useful metrics include:

Metrics should drive action.

Not just inventory growth.

Common Fourth-Party Risk Mistakes

Mistake 1: Assuming the direct vendor has it covered

The direct vendor should manage its subcontractors, but the organization still needs visibility into downstream risks that affect its services, data, and obligations.

Mistake 2: Tracking subprocessors only in privacy

Subprocessors matter to privacy, but fourth-party risk also affects cyber, resilience, AI governance, vendor risk, contracts, and customer assurance.

Mistake 3: Not linking fourth parties to data

A fourth party that processes sensitive data requires more attention than one with no data exposure.

Mistake 4: Not linking fourth parties to critical services

A fourth party with no direct data access may still create serious availability or resilience risk.

Mistake 5: Ignoring model providers

AI vendors may rely on model providers that process prompts, outputs, logs, or sensitive data.

Mistake 6: Not reviewing contract flow-down terms

If obligations do not flow down, the organization may have weak assurance over downstream controls.

Mistake 7: Not monitoring changes

Fourth-party relationships change after onboarding.

Subprocessor, model-provider, location, and support-provider changes should trigger review.

Mistake 8: Not dashboarding concentration risk

The same downstream provider may support many direct vendors.

That concentration can create enterprise risk.

30-Day Fourth-Party Risk Management Plan

Days 1–5: Define fourth-party scope

Define:

• fourth party

• subprocessor

This creates a practical fourth-party risk foundation quickly.

How Connected GRC Improves Fourth-Party Risk Management

Connected GRC improves fourth-party risk by linking:

• direct vendor

• fourth party

• subprocessor

• subcontractor

• model provider

• contract

• data inventory

• system inventory

• critical service

• geography

• risk tier

• evidence

• incident

• issue

• remediation

• validation

• risk acceptance

• dashboard

SmartSuite’s Third-Party Risk Management page describes connected vendor oversight with linked vendors, risks, controls, evidence, dashboards, onboarding, assessments, issues, and remediation. That connected model is exactly what fourth-party risk needs, because fourth-party exposure is not useful as a standalone list.

In a disconnected model, fourth-party information stays inside vendor questionnaires, privacy subprocessor lists, contract exhibits, and security reports.

In a connected model, fourth-party dependencies become visible in risk, data, resilience, AI, incident, issue, and executive dashboards.

That is how organizations move from vendor list management to ecosystem risk management.

A Practical Test for Fourth-Party Risk

Pick one critical vendor.

Ask whether your GRC model can show:

• direct vendor owner

• business service supported

• systems connected

• data processed

• subprocessors

• subcontractors

• cloud providers

• model providers, if AI is involved

• processing locations

• flow-down obligations

• evidence available

• fourth-party incidents

• fourth-party issues

• concentration dependencies

• change notification requirements

• risk acceptances

• dashboard status

• decisions needed

If answering those questions requires vendor questionnaires, privacy lists, contract exhibits, cyber reports, architecture diagrams, emails, and meetings, fourth-party risk is not connected enough.

That is common.

It is also the opportunity.

Final Thought

Your vendor ecosystem is deeper than your vendor list.

Direct vendors depend on other providers.

Those providers may host data.
They may process personal information.
They may deliver AI models.
They may provide infrastructure.
They may support operations.
They may create concentration risk.
They may be involved in incidents.
They may affect your ability to meet obligations.

Fourth-party risk management makes those hidden dependencies visible.

Connected GRC makes them governable.

Vendors connect to fourth parties.
Fourth parties connect to data.
Data connects to privacy obligations.
Fourth parties connect to systems.
Systems connect to cyber risk.
Fourth parties connect to critical services.
Critical services connect to resilience.
Model providers connect to AI governance.
Contracts connect to flow-down obligations.
Evidence connects to assurance.
Issues connect to remediation.
Risk acceptance connects to dashboards.
Dashboards connect to decisions.

That is fourth-party risk management in Connected GRC.

Not chasing every subcontractor equally.

Seeing the vendors behind your vendors — and focusing governance where the risk matters most.
