Digital infrastructure is more interdependent than ever, leaving organizations vulnerable to supply chain risks that most are unprepared to manage. If something goes wrong with a third-party vendor, the downstream effects can often prove substantial. When a widespread third party pushes a defective update, airlines ground and delay flights worldwide. When trusted Content Delivery Networks (CDNs) rely on a third party that experiences an outage, much of the Internet goes down. In Security Scorecard’s 2025 Supply Chain Cybersecurity Trends report, responses from nearly 550 CISOs and cybersecurity leaders worldwide revealed the following key finding: “Visibility is sorely lacking. Fewer than half of organizations monitor cybersecurity across even 50% of their nth-party supply chains.”

Whether you are evaluating the top rated EDI providers or trying to select the best EDI managed services partner for your business, there are some ways companies can monitor third-party cybersecurity risks effectively. These include developing a Third-Party Risk Management (TPRM) framework, conducting due diligence, and continuous monitoring.

Establishing a TPRM

To develop a TPRM, companies must establish a framework and define how the organization identifies, assesses, and responds to third-party risks. Vendors should be categorized and classified based on their risk level and your organization’s risk tolerance. Within the organization, TPRM roles and responsibilities must be clearly defined to ensure clarity and accountability for all parties involved in managing third-party risk.

To build a strong TPRM program, companies should:

• Establish a clear framework for identifying, assessing, and responding to third-party risks.

• Define internal roles and responsibilities to ensure accountability across departments.

• Categorize and classify third party vendors based on potential risk level

• Review and update regularly to stay aligned with evolving threats and regulations.

Conducting Due Diligence

There are several ways an organization can conduct thorough due diligence of their third parties. Before engaging with a third party, conduct an initial risk assessment to evaluate the vendors’ security practices, compliance, and overall risk profile. Organizations should utilize standardized questionnaires – such as the Vendor Security Alliance Questionnaire (VSAQ), Consensus Assessment Initiative Questionnaire (CAIQ), and Standard Information Gathering (SIG) – to gather information about vendors’ security posture. Highly trusted security rating platforms – like SecurityScorecard, Bitsight, UpGuard and RiskRecon – can be employed to assess vendors’ security performance. Independent audits – like a SOC 2 report – should be examined for further insight into a third-parties security posture.

Evaluating Third Party Vendor Risk

Continuous monitoring must be implemented to ensure the third party remains the best choice for an organization. Conducting regular risk assessments could identify new or emerging risks within the organization’s supply chain. Organizations should continually track their vendors’ performance against established metrics, industry averages, and similar third-party options. Some security ratings tools and platforms can track changes in vendor security postures over time, providing valuable insight into vendor volatility.
