The vendor risk management (VRM) market size is about 15.08 billion USD in 2026. The need to protect your assets through vendor relationships is not going away anytime soon. Experts estimate this number will grow to about 26.44 billion by 2031, at a CAGR of 11.89%. That's nearing double the amount this year.
This is because supply-chain cyber incidents surged by 431% between 2021 and 2023. Hackers realized accessing sensitive data from a company doesn't have to just come straight from the source. A company's cybersecurity standard is only as strong as its weakest third-party vendor.
In this guide we will go over what a third-party partner is and how to prioritize a risk management policy for them. We will also cover some tips on how to create and implement these policies. Listing key components you want to include and mistakes you'll want to avoid.
Third-party risk management policies explain how organizations manage risks connected to their vendors. This policy also extends to contractors, suppliers, and consultants. It defines how the organization identifies, assesses, monitors, and reduces third-party risks.
This policy serves as the foundation for an organization's third-party risk management program. Outlining the processes, responsibilities, and requirements teams must follow. Doing so helps to reduce risk while maintaining regulatory compliance.
A strong policy helps organizations test third-party relationships in a repeatable way. It also helps define acceptable risk tolerance. Utilizing these policies urges companies to follow the same vendor risk management practices.
You probably work with many different types of vendors. This might include cloud providers, payment processors, or other third-party service providers. A clear policy sets expectations before a relationship begins. It also guides you throughout the entire third-party risk management lifecycle.
Organizations depend on external service providers more than ever before. While these relationships help businesses operate more efficiently, they also create new risks. Every third-party vendor with access to sensitive data creates risk exposure. This is something your organization is responsible for.
Several factors contribute to the growth of third-party risks. Businesses continue to expand their cloud environments and outsource more critical business functions. They are relying on increasingly complex supply chains to support daily operations.
Cybercriminals continue to target vendors as a way to reach larger organizations. A security weakness at one vendor can create problems for many connected businesses. Regulators have also increased expectations around risk and compliance. As well as the oversight of third-party relationships.
Without proper governance, third-party relationships can create serious challenges. These challenges include data security incidents and operational disruptions. Issues can also look like financial loss, regulatory penalties, and reputational risk.
To address these concerns, organizations are placing more focus on managing third-party risks. They are creating stronger vendor risk management programs. They are also increasing monitoring efforts and developing policies. In hopes of helping to identify and reduce threats before they impact the business.
These policies create a consistent approach for evaluating and managing vendors. Without them, different departments may use different processes when reviewing vendors. Leading to missed vulnerabilities, inconsistent decision-making, and compliance gaps.
A comprehensive policy creates repeatable risk management practices across the organization. It helps align teams and different departments around the same goals and best practices.
Effective TPRM policies help organizations create stronger oversight by helping them:
A strong risk management program helps organizations understand their vendor landscape. It helps leaders identify potential risks and make informed decisions. It also supports a broader risk management framework that connects company-wide security practices.
The key components of a TPRM policy define how businesses manage risk with vendors. A strong policy creates a consistent process for teams to follow. It should help you reduce vendor risk while maintaining security and compliance requirements.
A comprehensive third-party risk management policy should explain how the organization manages vendors. From the first selection through the end of the relationship. It should also define who owns each step of the process and how teams should respond when risks change.
Every TPRM program should begin by explaining its purpose and scope. This section describes why the policy exists. It also goes over which vendors it applies to and what business functions it covers.
The scope should include all relevant third parties. This includes vendors, contractors, suppliers, and other providers that support business operations. It should also explain which types of vendor relationships need extra oversight, based on their level of risk.
A successful third-party risk management program requires clear ownership. The policy should define the responsibilities of every party involved. Whether that is the business owner, IT teams, compliance teams, risk teams, etc.
It should also explain the role of senior management and the board in overseeing vendor risk. Leadership involvement helps ensure third-party risks receive the attention and resources it needs. This in turn supports the organization's broader risk strategy.
Organizations should classify vendors based on their level of risk. Not every vendor creates the same level of exposure. Organizations should evaluate vendors based on factors like data access, impact, and services.
Vendors that handle sensitive information or support critical operations may need more oversight. Especially over another vendor that may have more limited access. Classifying these vendors helps organizations determine the appropriate level of monitoring.
Policies should go over exactly when to complete vendor risk assessments. These assessments help organizations understand a vendor's risk profile. They cover security practices for the vendors, too.
Risk assessments also make sure vendors meet business and regulatory requirements. The policy should explain how often teams should complete these assessments. And also what factors determine the level of review needed.
Organizations should complete due diligence before approving a new vendor. This process helps teams evaluate the vendor's security practices and financial stability. It also looks at their compliance history and ability to protect sensitive information.
During due diligence, organizations may review vendor documentation, certifications, contracts, and security practices. This information helps teams understand the potential risks associated with the relationship. A helpful step before moving forward with a partnership.
Note that your vendors may also partner with third parties. We refer to these as fourth-parties. Although you may not have direct contact with these companies, they still can serve as a risk.
Your vendor management policy can somewhat help you mitigate fourth-party risks. Ask your vendor to list any third-parties relevant to the services they provide to your organization. Add those fourth-parties to your inventory. You can then monitor them regularly and keep an eye out for potential risk events.
A third-party risk policy should define the minimum security requirements vendors must meet. These requirements may include security controls, access management practices, and data protection standards. Requirements might also include incident response procedures.
Organizations should evaluate a vendor's security posture through security assessments and security ratings. These reviews help to determine whether vendors can protect data and reduce risk.
Vendor risk does not end after onboarding. Organizations should watch partners to identify new changes in their security posture.
The policy should explain how teams track vendor performance and security incidents. It should guide businesses in reviewing risk changes and reassessing vendors when necessary. Ongoing monitoring helps organizations identify problems before they become major business disruptions.
A strong policy should establish how teams communicate vendor risks throughout the organization. Risk reporting helps leadership understand current risks, outstanding issues, and opportunities for improvement.
Organizations should also define how often they review and update the policy. As business needs, regulations, and threats change, organizations must continuously adjust their approach. This will help them remain effective in their efforts long-term.
Vendor risk management should never operate independently. Instead, it should be fully integrated into an organization's broader risk management framework. It should also be a part of an enterprise risk strategy.
Third-party vendors often impact many areas of the business. That's why managing vendor risk requires collaboration across departments. This beats leaving ownership to a single team by a mile. This coordinated approach helps organizations identify and respond to risks more effectively. Ensuring consistent governance throughout the risk management program.
An effective risk management program connects vendor oversight with key business functions. These include information security, internal audits, procurement, legal, business continuity, privacy, and compliance. Each department plays a unique role in evaluating and managing vendor relationships. From assessing cybersecurity controls and contractual obligations to ensuring regulatory requirements get met.
This integration allows for a more comprehensive view of an organization's risk landscape. Risk management activities related to third-party vendors can support the organization's broader enterprise risk strategy this way. Improving cross-functional communication and establishing consistent policies and decision-making across departments.
This approach strengthens governance and reduces risk exposure. Keeping businesses up to date on evolving business and cybersecurity threats.
Every vendor risk assessment should evaluate the risks associated with a vendor. Ideally, before you sign a contract and continue forward with this third-party relationship. Rather than treating assessments as a one-time exercise, organizations should regularly reassess vendors.
You never know when there may be changes in their services or business operations. Not to mention changing industry regulatory requirements and evolving cyber attacks. This ongoing assessment process helps organizations identify new vulnerabilities quickly. Stopping them in their tracks before they become significant risks.
A vendor risk assessment begins by reviewing essential vendor information. We are talking about services provided, access to sensitive data, and the vendor's role in your business. The whole nine yards.
Organizations often use questionnaires to gather these important details. Going over the vendor's security practices, compliance efforts, and operational processes.
Businesses should check the vendor's security posture by reviewing any existing security controls. As well as independent security ratings, financial stability, and incident response capabilities. This helps compliance officers better understand the vendor's overall level of risk.
Use these findings to determine the vendor's risk level and establish appropriate oversight. Some people use risk scoring models to rank remediation efforts and identify high-risk vendors. They also use them to determine how often they should track or reassess them. By taking this structured approach to assessments, organizations can strengthen vendor risk management. Overall, reducing their cybersecurity risk and making better decisions throughout the vendor lifecycle.
Many organizations struggle with managing third-party risk. Focusing on onboarding instead of viewing risk management as an ongoing process. They might forget they need to practice compliance throughout the entire lifecycle.
Yes, onboarding is an important step. But vendor risk can change over time. This happens as vendors introduce new services, change security practices, or face new threats. Without continuous oversight, organizations may miss critical vulnerabilities. Increasing their overall risk exposure.
Some of the most common mistakes organizations make when managing third-party relationships include:
By avoiding these common mistakes, organizations can create stronger policies. Strengthening governance and maintaining better visibility into the risks associated with vendors.
Third-party vendors help businesses save time, lower costs, and improve daily operations. However, every vendor also brings some level of risk. Without a clear plan, those risks can lead to all kinds of issues. Namely, data breaches, compliance issues, financial losses, or disruptions to your business.
A strong third-party risk management policy gives your team a clear process to follow. It explains how to choose vendors, review their security and monitor them over time. Instead of reacting to problems, you can identify and reduce risks before they happen.
Remember that vendor risk management is not a one-time task. Your vendors, your business, and cybersecurity threats will continue to change. Review your policy regularly and update it as needed.
