Your Vendors May Be Your Biggest Compliance Risk

Most organizations no longer operate within a clearly defined technology perimeter. Critical functions are spread across cloud providers, SaaS platforms, managed service providers, payroll processors, payment systems, contractors and other third parties.

That creates a fundamental compliance problem: a company may outsource a service, but it often cannot outsource responsibility for protecting the systems and data involved.

The risk is growing quickly. Verizon’s 2026 Data Breach Investigations Report found that third-party involvement was present in 48% of breaches, up from 30% the previous year, a 60% year-over-year increase. (verizon.com)

For companies still treating vendor risk as a procurement exercise or annual questionnaire, those numbers should be hard to ignore.

The Security Perimeter Now Extends to Your Vendors

A company’s cybersecurity environment is no longer limited to the technology it owns. A payroll provider may hold Social Security numbers and banking information. An MSP may maintain privileged credentials. A cloud provider may host critical applications and databases.

Each connection creates another dependency and, potentially, another path into the organization.

The financial impact can be significant. IBM’s 2025 Cost of a Data Breach Report calculated the global average cost of a breach at $4.44 million. In the United States, the average reached $10.22 million, while healthcare organizations averaged $7.42 million. (ibm.com)

Those costs go far beyond technical cleanup. They can include downtime, forensic investigations, legal expenses, regulatory scrutiny, customer notification and lost business.

When a third party causes the incident, those consequences do not necessarily stay with the vendor.

“It Was Our Vendor” Does Not Eliminate the Compliance Problem

Regulators are placing greater emphasis on third-party oversight. Organizations are increasingly expected to know which vendors have access to sensitive information, assess their risk, include security obligations in contracts and monitor critical providers over time.

The New York Department of Financial Services made this clear in its October 2025 third-party guidance. NYDFS said regulated entities should use a risk-based approach covering due diligence, contracting, ongoing monitoring and termination. It also warned that organizations cannot simply delegate responsibility for cybersecurity compliance to a third party. (dfs.ny.gov)

The European Union’s Digital Operational Resilience Act, or DORA, takes a similar position. Financial entities using third-party technology providers remain fully responsible for meeting their regulatory obligations. (eur-lex.europa.eu)

The specific rules differ by industry and jurisdiction, but the direction is clear: regulators increasingly expect meaningful oversight of third parties that can affect critical systems or sensitive data.

Third-Party Risk Has Become a Compliance Priority

Companies are responding. KPMG’s 2026 Global Third-Party Risk Management Survey found that 48% of organizations identified regulatory compliance as a leading driver of third-party risk programs, followed by cybersecurity risk at 37%. (kpmg.com)

Organizations are also spending heavily in this area. According to KPMG, 52% reported spending on risk assessment and due diligence, 51% on third-party risk technology, 49% on cybersecurity and data protection, and 45% on regulatory audits.

Yet many programs are still immature. Only 18% said third-party risk management was fully integrated with enterprise risk management. (kpmg.com)

That gap matters because companies cannot manage third-party risk if they do not know who their critical vendors are, what they can access and how important they are to operations.

The Vendor Inventory Is Often Larger Than Expected

Ask an executive to name the company’s critical technology providers and the answers are usually obvious: Microsoft, Google, AWS, the MSP or the ERP platform.

But the real ecosystem is much larger.

Payroll and benefits providers hold employee data. Accounting systems process financial information. Marketing platforms store customer records. Backup providers maintain copies of corporate data. Software developers may access source code or production systems. Consultants, contractors and subcontractors may also hold sensitive information.

Then there are fourth parties, the vendors used by your vendors.

That leads to a basic but important question: Can the organization identify which outside parties have access to sensitive data or critical systems, and explain how those risks are being managed?

If not, the company may already have a governance problem.

A SOC 2 Report and a Questionnaire Are Not Enough

Vendor assessments often become checkbox exercises. A questionnaire is completed. A SOC 2 report is collected. The vendor is approved.

Those documents can be useful, but they are not the same as effective risk management.

NYDFS notes that questionnaires can help collect information, but qualified personnel still need to interpret the answers, ask follow-up questions and determine whether additional controls are needed. Its guidance also recommends reviewing areas such as access controls, encryption, incident response, business continuity, vulnerability management and downstream providers. (dfs.ny.gov)

The Federal Trade Commission makes a similar point. Its guidance recommends evaluating service providers before outsourcing sensitive functions, adding security requirements to contracts and then verifying compliance rather than simply accepting assurances. (ftc.gov)

Vendor risk changes over time. Providers add new technology, change subprocessors, acquire companies, lose employees and become more deeply integrated with customer systems.

Third-party risk management therefore needs to be an ongoing lifecycle process, not a one-time approval.

Contracts Are Part of the Security Control Environment

Vendor risk does not live only in technical controls. It also lives in the contract.

If a provider suffers a breach, how quickly must it notify you? What information must it provide? What security controls must it maintain? Can it use subprocessors? Where can your data be stored? What happens to that data when the relationship ends?

These questions may seem routine during contract negotiations. During an actual incident, they can become critical.

NYDFS specifically recommends contractual protections around areas such as multifactor authentication, encryption, incident response, business continuity and monitoring. It also recommends planning for how an organization would transition away from a critical provider if necessary. (dfs.ny.gov)

A strong technical environment can still be undermined by a weak vendor agreement.

Not Every Vendor Requires the Same Level of Scrutiny

Third-party risk management should be risk-based. A supplier of office furniture should not receive the same level of review as an MSP with administrator privileges.

Organizations should focus first on vendors that:

• store or process sensitive information;
• maintain privileged access;
• connect directly to internal systems;
• support critical operations;
• process financial or employee data; or
• could materially disrupt the business if they failed.

Those providers deserve deeper due diligence and stronger ongoing oversight.

Depending on the risk, that may include reviewing security certifications, penetration-testing information, incident response capabilities, authentication controls, cyber insurance and subcontractor relationships.

The goal is not to eliminate third-party risk. That is impossible.

The goal is to identify it, prioritize it and show that it is being managed deliberately.

You Can Outsource the Service. You Cannot Assume You Outsourced the Risk.

Third-party technology is indispensable. Few organizations could operate today without cloud infrastructure, SaaS platforms, managed services and outside specialists.

But outsourcing creates dependency, and dependency creates risk.

The progression in Verizon’s data is telling. Third-party involvement accounted for 30% of breaches in the 2025 DBIR and 48% in the 2026 report. (verizon.com)

At the same time, regulators are emphasizing due diligence, contractual protections, ongoing monitoring and executive oversight.

The question is no longer simply:

“Are our vendors secure?”

It is:

“Do we know which vendors could materially affect our security and compliance obligations, and can we demonstrate that we are managing those risks?”

For many organizations, the answer may reveal one of their largest remaining compliance gaps.
