Third-Party AI Risk: Managing Model Provider Dependence

The Concentration Concern

Regulators including the FCA, PRA, and Bank of England have flagged concern about the financial services industry's growing dependence on a small number of AI model providers. If many firms rely on the same underlying AI systems, a failure or vulnerability at one provider could have systemic implications.

For SMEs, this creates a tension: the most capable AI comes from large providers, but dependence on those providers creates risk.

Understanding Third-Party AI Risk

Types of AI Provider Relationships

Direct API Access:

  • Using OpenAI, Anthropic, Google AI directly
  • Maximum capability, maximum dependence
  • Data flows to provider
  • Pricing and availability controlled by provider

Embedded AI:

  • AI features in existing software
  • Less visible dependence
  • Still subject to provider changes
  • May cascade through supply chain

Specialist Financial AI:

  • Credit scoring providers
  • Fraud detection services
  • AML screening tools
  • Regulatory-aware but still third-party

What Could Go Wrong

Operational:

  • Service outages affecting your operations
  • Performance degradation
  • Capacity constraints during peaks
  • Geographic availability issues

Commercial:

  • Pricing changes
  • Terms and conditions changes
  • Service discontinuation
  • Provider acquisition or exit

Compliance:

  • Provider compliance failures
  • Data handling changes
  • Regulatory actions against provider
  • Cross-border complications

Security:

  • Provider security breaches
  • Model vulnerabilities exploited
  • Data exposure
  • Malicious model manipulation
Warning

Third-party AI risk is particularly acute in financial services because of the regulatory focus and systemic risk concerns. The FCA expects firms to actively manage this risk.

Regulatory Expectations

FCA Perspective

The FCA expects firms to:

  • Understand their third-party AI dependencies
  • Conduct appropriate due diligence
  • Have contingency arrangements
  • Monitor provider performance
  • Maintain accountability for outcomes

Operational Resilience

New operational resilience requirements apply:

  • Important business services identified
  • Impact tolerances defined
  • Third-party dependencies mapped
  • Testing and planning conducted

AI providers supporting important services need resilience consideration.

Senior Manager Accountability

Senior managers remain accountable:

  • Can't outsource responsibility
  • Must understand dependencies
  • Required to oversee arrangements
  • Liable for compliance failures

Third-party AI risk requires systematic identification, assessment, and management

Due Diligence Framework

Before Adoption

Technical Assessment:

  • How does the AI work?
  • What data is required?
  • What security controls exist?
  • What's the reliability track record?

Operational Assessment:

  • Service level commitments
  • Support arrangements
  • Change notification processes
  • Geographic considerations

Commercial Assessment:

  • Pricing structure and stability
  • Contract terms
  • Lock-in provisions
  • Exit arrangements

Compliance Assessment:

  • Provider's regulatory status
  • Compliance with relevant standards
  • Data protection arrangements
  • Incident notification provisions

Questions to Ask

AreaKey Questions
SecurityWhat certifications? How is data protected? What's the breach history?
AvailabilityWhat's the SLA? What's actual performance? What's the redundancy?
DataWhere is data processed? Is it used for training? Who can access it?
ComplianceWhat regulatory oversight applies? How are changes managed?
ContinuityWhat if the provider fails? What's the exit process?

Red Flags

  • No security certifications
  • Poor or no SLA
  • Vague data handling terms
  • No exit provisions
  • History of significant incidents
  • Lack of transparency
  • Resistance to due diligence
Pro Tip

Major AI providers generally have good security. The risk is often more about dependence and exit than about provider competence.

Resilience Planning

Reducing Single Points of Failure

Multi-Provider Strategy:

  • Use multiple AI providers where practical
  • Avoid dependence on single source for critical functions
  • Build switching capability
  • Accept some cost/complexity trade-off

Hybrid Approaches:

  • Combine cloud AI with on-premises capability
  • Use AI to augment rather than replace
  • Maintain manual fallback for critical processes
  • Build internal expertise

Contingency Arrangements

For Service Interruption:

  • Identify impact on your operations
  • Define response procedures
  • Test contingency arrangements
  • Communicate with stakeholders

For Provider Failure:

  • Understand data portability
  • Identify alternative providers
  • Maintain documentation for switching
  • Consider exit costs in planning

Monitoring

Ongoing Assessment:

  • Track service performance
  • Monitor provider news and developments
  • Review contracts periodically
  • Update risk assessments

Early Warning:

  • Watch for provider difficulties
  • Note changes in service quality
  • Track industry developments
  • Maintain provider relationship

Contractual Protections

Key Terms to Include

Service Levels:

  • Availability targets
  • Performance metrics
  • Consequences for failure
  • Measurement and reporting

Data Protection:

  • Processing limitations
  • Security requirements
  • Breach notification
  • Data return/deletion

Change Management:

  • Advance notification of changes
  • Right to terminate on material change
  • Version control where relevant
  • Testing arrangements

Exit:

  • Data portability provisions
  • Transition assistance
  • Post-termination obligations
  • Reasonable notice periods

Negotiation Reality

Large Providers:

  • Standard terms often non-negotiable
  • SMEs have limited leverage
  • Focus on understanding rather than changing
  • Consider terms in adoption decision

Specialist Providers:

  • More room for negotiation
  • Custom terms possible
  • Build relationship for flexibility
  • Document agreed variations

Documentation Requirements

What to Document

Provider Assessment:

  • Due diligence conducted
  • Risk assessment
  • Approval decision and rationale
  • Ongoing monitoring plan

Operational Arrangements:

  • How AI is used
  • Integration with your systems
  • Responsibility allocation
  • Incident response

Review Schedule:

  • Regular review cadence
  • Trigger events for early review
  • Documentation requirements
  • Accountability for review

Demonstrating Compliance

When regulators ask, you should be able to show:

  • You understand your AI dependencies
  • You've conducted appropriate due diligence
  • You have contingency arrangements
  • You're monitoring ongoing
  • Someone is accountable
Info

Documentation isn't bureaucracy—it's evidence that you're managing risk responsibly. In regulatory review, documented thinking carries weight.

Proportionate Approach

Risk-Based Assessment

Not all third-party AI requires the same scrutiny:

UseRisk LevelApproach
Document automationLowerBasic due diligence
Customer chatbotMediumStandard assessment, monitoring
Credit decisionsHigherComprehensive assessment, ongoing oversight
Fraud detectionHigherDetailed scrutiny, multiple controls

SME Practical Reality

  • You can't negotiate with OpenAI like a major bank
  • Perfect alternatives may not exist
  • Some concentration is unavoidable
  • Focus on understanding and contingency

The goal isn't eliminating risk—it's managing it appropriately.

Frequently Asked Questions

Why are regulators concerned about third-party AI concentration in financial services?

Regulators including the FCA, PRA, and Bank of England worry that if many firms rely on the same underlying AI systems from a small number of providers, a failure or vulnerability at one provider could have systemic implications across the financial services industry.

What due diligence should financial firms conduct on AI providers?

Firms should assess technical aspects (how the AI works, security controls, reliability), operational factors (service levels, support, change notifications), commercial terms (pricing stability, exit arrangements), and compliance (regulatory status, data protection, incident notification).

Can SMEs negotiate better terms with major AI providers like OpenAI?

Large AI providers typically offer non-negotiable standard terms, and SMEs have limited leverage. The focus should be on understanding terms before adoption rather than changing them. Specialist financial AI providers may offer more room for negotiation.

What contingency arrangements should firms have for AI provider failures?

Firms should understand data portability, identify alternative providers, maintain documentation for switching, consider exit costs, and for critical processes, maintain manual fallback capabilities or hybrid approaches combining cloud AI with on-premises options.
