Third-Party Risk Readiness Checklist
A guide to help you assess your organization’s readiness to strengthen third-party risk management (TPRM) and reduce supply chain disruption risk.
Is Your Vendor Ecosystem Increasing Your Cyber and Operational Exposure?
As companies move to a cloud-first infrastructure, third-party risk is appearing in more breaches and resulting in more business interruptions. In fact, third-party involvement in breaches doubled to 30% last year.1 In a 2025 survey of CISOs, 91% reported an increase in third-party incidents.2 And only 3% said they have full supply chain visibility.2
If vendor oversight is treated as a point-in-time compliance check, your organization can lose visibility after contracts are signed. A modern TPRM program pairs risk-based onboarding and enforceable requirements with full lifecycle monitoring, automation and clear accountability.
This checklist can help you determine whether you have the visibility, governance and response capabilities to manage third-party risks continuously, not just during annual reviews.
Five Areas to Strengthen Third-Party Risk Readiness
Visibility — Build a Complete Vendor and Access Population
A strong program starts with knowing who is in your ecosystem, what they can access and what business processes depend on them. Include cloud services, managed providers, connected products and OT/IoT relationships.
- Do you maintain a living roster of third parties, fourth parties and critical suppliers with an identified business owner for each relationship?
- Is your third-party inventory kept current through defined intake and updated workflows across procurement, IT and business owners?
- Have you documented what data, systems and identities each vendor can access, including integrations, APIs and privileged accounts?
- Can you quickly identify which vendors touch regulated data or support critical information that affects safety or uptime?
Onboarding and Due Diligence — Standardize Assessments Using Risk Tiers
Consistent intake helps you scale. Use inherent risk tiering to determine what evidence you require, who approves exceptions and how you validate responses. Where appropriate, use automation to reduce repetitive evidence collection and speed reviews.
- Do you tier vendors by inherent risk and apply deeper due diligence to high-risk relationships?
- Do you validate key controls with evidence such as security reports and testing summaries, not only questionnaires?
- Are responsibilities clear across security, privacy, procurement, legal and business stakeholders for onboarding decisions?
Contracts and Governance — Make Requirements Enforceable
Contracts should translate policy into requirements vendors must meet throughout the relationship. Governance should ensure changes in scope trigger reevaluation before risk grows.
- Do contracts include clear security requirements, SLAs, breach notification timelines, subcontractor controls and rights to audit language?
- Are access management, data retention and encryption requirements aligned to your internal policies and regulatory obligations?
- Do you reassess risk when scope changes occur, such as new integrations, acquisitions, geographic expansion or access to additional data?
- CDW can review system and organization controls (SOC) reports for relevant vendors for deficiencies and address required complementary user entity controls. This is a must-have exercise for vendor management, information security and SOX (financial) reporting.
Resilience and Response — Plan for Third-Party Disruption
Assume critical vendors will have an incident. Prepare for outages, ransomware and supplier failures with defined communications, containment steps and business continuity options.
- Do you have shared incident response expectations with critical vendors, including points of contact, notification methods and after-hours escalation?
- Can you isolate or disable vendor access quickly while maintaining essential operations and safety?
- Have you tested business continuity plans for vendor outages and supply chain disruptions, including alternate providers or manual workarounds?
- Have roles and responsibilities been clearly defined with regard to incident response and business continuity?
- Has your organization conducted tabletop exercises to ensure that your incident response plan works and those who are responsible are well trained to respond?
Continuous Monitoring and Remediation — Move Beyond Annual Reviews
Annual assessments miss fast-moving changes like new exposures, end-of-life technology and shifting ownership. Continuous monitoring helps you detect drift and drive remediation before issues become incidents.
- Can you continuously monitor critical vendors for key risk signals such as exposed services, leaked credentials, patch posture and compliance changes?
- Do you track remediation actions with timelines, escalation paths and decision points for risk acceptance when vendors cannot or will not resolve issues?
- Are you using automation and AI to reduce assessment cycle time and focus analysts on the highest risk findings?
