According to the Chartered Institute of Internal Auditors, "cybersecurity and data security" was identified as the single greatest risk for businesses in 2026, with over 80% of internal auditors in the UK and Europe flagging it as a top threat. But here's what most executives miss: over 60% of data breaches now involve third parties.
Your suppliers, contractors, and software vendors have become the weakest link in your security chain. "In 2026, CEOs will manage cyber exposure across their suppliers as tightly as they manage cash flow." Yet only a small portion of organizations report visibility across third-, fourth-, and nth-party relationships. Most operate with partial insight limited to direct vendors or a narrow segment of the extended supply chain.
The Third-Party Threat Landscape Reshaping UK Enterprises
The last two years saw a significant spike in supply-chain-related breaches. Tom expects this trend to continue and intensify. Third-party cyber risk continues to concern security leaders as vendor ecosystems grow, supply chains stretch, and AI plays a larger role in business operations. A recent Panorays survey of U.S. CISOs shows rising third-party incidents and growing regulatory attention, while visibility beyond direct vendors and the resources to manage that risk continue to fall short.
An inefficient VRM program is likely to miss critical data breach attack vectors in your third-party threat landscape, an error that could cost you USD 4.66 million. The average damage cost for data breaches involving third parties is USD 4.66 million, $216,441 higher than the global average of USD 4.45 million.
The threat vectors have evolved dramatically in 2026:
- AI-Enhanced Attacks: Cyber threats in 2026 are increasingly AI-driven. As a result, we are seeing a surge in high-fidelity "deepfake" used to bypass traditional verification in UK businesses.
- Supply Chain Amplification: Attackers are focusing further down the supply chain, targeting SME vendors.
- Extended Attack Surface: Vendor relationships touch nearly every core business function, from cloud infrastructure and software development to data processing and AI services. Each added dependency expands the attack surface and increases the number of organizations involved in protecting sensitive systems and data.
Why Traditional Vendor Management Fails in 2026
Most UK enterprises still rely on outdated approaches that create dangerous blind spots. Traditional vendor security questionnaires show similar limitations. CISOs describe them as static and poorly suited to ongoing assessment. Periodic reviews often miss changes that occur between cycles, especially when vendors rely on their own extended networks.
The Fatal Flaws:
- Annual Assessment Fallacy: A shift away from annual questionnaires, with greater demand for automated, ongoing monitoring.
- Limited Visibility: CISOs say limited visibility complicates incident response, risk prioritization, and compliance planning. When a breach emerges several layers removed from a known vendor, security teams may struggle to understand exposure, timelines, and downstream impact.
- Resource Constraints: As vendor counts grow into the hundreds or thousands, manual workflows add strain to security teams and increase the likelihood that emerging risks go unnoticed.
Building Effective Vendor Risk Management in 2026
A Vendor Risk Management framework outlines how vendor security risks should be managed in your VRM workflow. A VRM framework sets guidelines for mitigating and managing cybersecurity risks across four primary stages of the vendor lifecycle.
Vendor Inventory and Classification
Create an inventory of your external vendors. While daunting, you must do this and not miss out on any. You can delegate this amongst departments to compile a list. Start by developing a scoring matrix that considers the vendor's criticality to your business operations and the level of risk posed by them.
Key Classification Criteria:
- Data access levels (low/medium/high)
- Business criticality (operational/strategic/essential)
- Geographic location and jurisdiction
- Financial stability assessment
Due Diligence and Risk Assessment
Ensuring security teams only consider vendors with an acceptable potential impact on the organization's security posture. This includes:
- Security certifications review (ISO 27001, SOC 2, Cyber Essentials)
- Financial stability evaluation
- Request a quarterly "Attack Surface" snapshot. Ask your vendor to deliver a brief report every quarter showing all internet-exposed assets (public IPs, URLs, open ports) and any changes since the last report. This gives you an up-to-date view of their external footprint and highlights new exposures before attackers do.
Continuous Monitoring Implementation
Continuous monitoring of onboarded vendors to ensure their risk profiles always remain within acceptable limits. Move beyond static assessments to real-time intelligence:
- Automated vulnerability scanning
- Dark web monitoring for credential exposure
- Financial health tracking
- Security incident alerts
Incident Response and Offboarding
Ensuring best cybersecurity practices are followed when vendor relationships cease, such as ensuring the company's digital footprint is reduced every time a vendor is offboarded.
AI-Specific Vendor Risk Considerations
CISOs view AI vendors as carrying a distinct risk profile. Concerns focus on data handling practices, limited transparency into models, and unpredictable behavior in AI-driven systems. Despite this awareness, many organizations still onboard AI vendors through general third-party processes. Dedicated onboarding policies for AI vendors remain limited, particularly among smaller enterprises.
For AI vendors, your assessment framework must include:
- Data Governance: How is training data sourced, stored, and protected?
- Model Transparency: Can you audit decision-making processes?
- Bias and Ethics: What measures prevent discriminatory outcomes?
- Intellectual Property: Are you exposed to copyright infringement claims?
Businesses relying on third-party AI solutions must ensure rigorous oversight, ethical governance, and proper validation before implementation. Require AI vendors to provide model cards, bias testing results, and clear data lineage documentation.
Regulatory Pressure Intensifies
CISOs report rising regulatory scrutiny tied to third-party cyber risk. Regulatory frameworks place greater expectations on organizations to demonstrate oversight across vendor ecosystems, including indirect relationships. Only a minority of organizations feel ready to meet upcoming requirements without major changes.
Key UK regulatory developments affecting vendor risk management:
- DORA Implementation: With DORA (Digital Operational Resilience Act) now in force, financial institutions must ensure that third-party providers meet stringent ICT risk management, cybersecurity, and resilience requirements.
- Cyber Resilience Bill: Enhanced incident reporting requirements
- Data Protection Evolution: Extended liability for processor breaches
Technology Solutions That Actually Work
Vendor Risk Management Market size was over USD 10.18 billion in 2025 and is poised to exceed USD 40.47 billion by 2035, growing at over 14.8% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of vendor risk management is estimated at USD 11.54 billion.
The most effective VRM platforms in 2026 combine:
- AI-Powered Risk Scoring: Dynamic assessment based on multiple data sources
- Automated Compliance Tracking: Real-time monitoring against regulatory frameworks
- Threat Intelligence Integration: External threat feeds and dark web monitoring
- Workflow Automation: Streamlined assessment and approval processes
Leading vendors include BitSight, SecurityScorecard, and UpGuard for continuous monitoring, while ProcessUnity and ServiceNow offer comprehensive platform approaches.
Building Resilience Beyond Technology
In 2026, organisations will recognise that cyber resilience is not just firewalls and detection tools, but that it hinges on how well people perform under pressure. Crisis readiness will be measured in the same way that organisations track financial or operational performance. Boards will expect regular simulations, scenario planning and cross-department training to become core operational requirements as threats evolve, so that operational staff can take coordinated action when the unexpected happens.
Your VRM program must include:
- Regular Tabletop Exercises: Test response procedures with vendor-specific scenarios
- Cross-Functional Training: Ensure legal, procurement, and IT teams understand their roles
- Board-Level Reporting: Real-time telemetry, automated variance alerts, and board-level KPIs will track vendor health daily.

The Bottom Line
Looking ahead to 2026, cyber security is not about panic or complexity. It is about control, resilience and using the right support so security becomes an everyday part of how you work, not something that constantly interrupts it.
Vendor risk management isn't just about compliance—it's about business survival. Fast forward to 2025, and vendor risk rating has become more than a regulatory requirement—it's a strategic necessity. Organizations today operate in an interconnected digital ecosystem where third-party failures can trigger financial losses, operational disruptions, and reputational damage.
The enterprises that thrive in 2026 won't be those with the most vendors—they'll be those with the most visibility, control, and resilience across their extended digital ecosystem. Start building that capability today, because your next breach might not come from your own systems—it might come from theirs.
