The “Why”: The Escalating Stakes of Vendor Relationships

For mid-market companies, vendors often serve as an extension of your own team, filling critical needs where a full-time employee might not be feasible. As Kyle notes, CIT looks for solutions that “solve true business needs for our customer sides,” especially for small to mid-sized businesses that “definitely have a need for the solution” but lack enterprise-level staff. This reliance means that a vendor’s vulnerabilities can quickly become your own.

The threat landscape is continuously evolving. In 2025, third-party breaches are a significant concern, with nearly 30% of all data breaches involving third-party suppliers, a 100% increase from previous years, according to the Verizon Data Breach Investigations Report. Gartner forecasts that 45% of organizations worldwide will experience supply chain breaches by the end of 2025, a threefold increase from 2021. This underscores the critical importance of Third-Party Risk Management (TPRM).

The Hidden Dangers: Risks of Inadequate Vetting

Todd emphasizes that without a formal way of evaluating vendors, organizations “are just automatically inheriting any risk that they may present to your organization.” This can manifest in several critical areas:

• Cybersecurity Risk: As Todd points out, “98 percent of companies work with somebody that’s had some sort of security event.” Recent incidents in 2025, such as the Chain IQ Group AG cyberattack impacting 19 clients and the Qantas breach via an offshore contact-center platform, highlight how a vendor’s security lapse can have widespread consequences for their clients. The average cost to remediate a breach originating from a third-party system is nearly $4.8 million in 2025, higher than breaches caused by internal systems alone.
• Financial Risk: A vendor’s financial instability can lead to service disruptions, project delays, or even outright failure to deliver, directly impacting your business operations and potentially incurring significant costs to find and onboard a new provider.
• Reputational Damage: A security incident or service failure by a vendor can severely tarnish your company’s reputation, eroding customer trust and potentially leading to lost business.
• Regulatory Non-Compliance: Especially in regulated industries like banking and finance, your security program is only as strong as your weakest link. Regulations often mandate that your partners’ security policies must be at least as secure as your own. Failure to ensure this can result in hefty fines and legal repercussions. For instance, GDPR enforcement has become more aggressive in 2025, with fines exceeding €6.2 billion since its inception.

The Upside: Benefits of Proactive Due Diligence

While the risks are substantial, the benefits of thorough vendor vetting are equally compelling, fostering stronger, more reliable partnerships.

• Enhanced Security Posture: By scrutinizing a vendor’s security controls, you proactively identify and address potential vulnerabilities before they can be exploited. This includes looking for compliance with standards like SOC 2, which has become a “gold standard” for demonstrating data security and trust in 2025.
• Regulatory Assurance: For mid-market companies navigating complex compliance landscapes, robust vetting ensures your vendors meet necessary regulatory requirements (e.g., GDPR, CCPA, SOC 2). In 2025, both GDPR and CCPA have seen updated regulations, emphasizing the need for continuous vigilance in data privacy and cybersecurity audits.
• Business Continuity: Partnering with financially stable and operationally sound vendors minimizes the risk of disruptions, ensuring your critical business functions remain uninterrupted.
• Strategic Alignment and Growth: As Kyle emphasizes, choosing vendors that can “grow with you” requires asking questions about their long-term vision and ability to solve evolving needs. This foresight turns a vendor into a true strategic partner.
• Cost Efficiency: While comprehensive vetting requires an upfront investment of time and resources, it ultimately prevents far greater costs associated with breaches, downtime, and legal penalties.

Beyond the Basics: Overlooked Elements of the Vetting Checklist

While security and data privacy are often top-of-mind, some critical elements are frequently missed in vendor vetting checklists:

1. Financial Stability and Future Viability: Todd highlights the importance of ensuring “a strong financial backing of the partner you’re working with.” This goes beyond basic solvency. Kyle adds a crucial layer: assessing the likelihood of a vendor being acquired. A change in ownership, especially from a founder-led visionary to private equity, can “shift the quality and the future of the products.” Reviewing financial statements (balance sheets, income statements, cash flow), credit ratings, and debt-to-equity ratios are essential steps.
2. Account Management and Support: Will your organization receive dedicated account management? As Kyle notes, a good representative who engages with your teams and keeps you “aware of changes and what’s coming” makes a significant difference. Responsive and effective support is crucial for resolving issues quickly.
3. Company Culture Alignment: This isn’t a checkbox item but a critical factor for long-term partnership success. As Kyle explains, you get a “feel for it” through conversations, probing questions about their work environment, and even social media review. Todd adds that referrals from other C-level organizations can provide quick insights into a company’s culture. Cultural fit ensures smoother communication, shared goals, and a more collaborative approach.
4. Disaster Recovery and Business Continuity Plans: Beyond just security, how resilient is the vendor in the face of an outage or disaster? This is particularly important for critical vendors. Todd emphasizes that for compliance-driven organizations, actually reading and evaluating a vendor’s disaster recovery plan against your expectations is paramount, not just checking a box.
5. Post-Event Transparency and Improvement: If a vendor has experienced a security event, don’t immediately rule them out. As Todd suggests, understanding “how did that happen? What did you do about it? How has it gotten better?” can reveal a vendor that has significantly strengthened its security posture. Sometimes, a past problem can make them “more attractive in some regards,” as Kyle observes, due to heightened attention to security.

Ongoing Vigilance: Re-evaluating Vendor Relationships

Vendor vetting isn’t a one-time event; it’s a continuous process. Todd recommends re-evaluating critical vendors at least annually. For rapidly evolving solutions or core business applications, quarterly or even monthly check-ins may be necessary to understand roadmaps, new features, and potential changes. This continuous monitoring helps identify “erosion of problems” early and ensures ongoing alignment with your business needs and risk appetite.

Practical Advice for Non-Compliant Industries

For businesses not bound by strict regulatory compliance, Todd offers actionable advice:

1. Start with Fiscal Health: Prioritize assessing a vendor’s financial stability to ensure they are a solvent company “going to be around for the long haul.”
2. Request Security Safeguards: Inquire about their security controls and ask for documentation like ISO or SOC 2 reports. Even if you’re not formally compliant, these reports provide valuable insights into their data protection practices.
3. Ask for a “Due Diligence Package”: Todd’s top tip: simply ask, “Can you send me your due diligence package?” This broad request will prompt them to provide their standard information, giving you a strong starting point to review and identify any missing pieces.

By adopting a comprehensive, proactive, and continuous approach to vendor vetting, mid-market C-Suite executives can transform potential risks into robust, growth-enabling partnerships.

Frequently Asked Questions

Q: Why is vendor vetting particularly important for mid-market companies?
A: Mid-market companies often rely heavily on third-party vendors to provide specialized solutions and services, effectively acting as extensions of their internal teams. Unlike larger enterprises, they may lack the extensive in-house resources to manage all IT needs, making the thorough vetting of these partners crucial to avoid inheriting significant cybersecurity, financial, and operational risks.

Q: What are the biggest risks if a mid-market company neglects vendor due diligence?
A: The biggest risks include data breaches and cyberattacks originating from a vendor’s compromised systems, substantial financial losses due to a vendor’s instability or service failure, damage to the company’s reputation, and severe penalties for non-compliance with regulatory requirements like GDPR or CCPA.

Q: How often should we re-evaluate our existing vendors?
A: Critical vendors, especially those handling sensitive data or essential operations, should be re-evaluated at least annually. For vendors providing rapidly evolving technology or core business applications, more frequent reviews (quarterly or even monthly) are advisable to stay abreast of their roadmap, security posture, and any changes that could impact your business.

Q: What is the single most important question to ask a potential vendor if you’re just starting a vetting program?
A: A great starting point is to simply ask, “Can you send me your due diligence package?” This request will prompt the vendor to provide their standard set of information, offering a comprehensive overview of their security, compliance, and operational practices, which you can then review and use as a foundation for further inquiry.

Q: How does a vendor’s company culture impact a partnership, and how can we assess it?
A: A vendor’s company culture directly influences communication, responsiveness, problem-solving, and overall collaboration. Cultural misalignment can lead to friction, delays, and unmet expectations. While not a checklist item, it can be assessed through open conversations, probing questions about their operational philosophy, reviewing their online presence, and, most effectively, by seeking referrals from other C-suite executives who have direct experience working with them.
