Third-party relationships are now central to how organizations operate. They enable scale, innovation, and efficiency across increasingly complex digital ecosystems. But they also represent one of the greatest sources of cyber risk.

The 2026 HITRUST Trust Report highlights a growing “Trust Crisis” facing cybersecurity and risk leaders. As organizations expand their reliance on vendors, supply chains, cloud providers, and emerging technologies, the challenge is no longer just managing internal security.

Third-Party Risk Is Accelerating

The data is clear. Supply chain risk is not just increasing. It is reshaping cybersecurity.

According to the 2025 Verizon Data Breach Investigations Report, third-party related breaches have doubled from 15% to 30% in the past year. This reflects a broader shift in attacker behavior. Vendors and service providers are increasingly targeted because compromising one supplier can provide access to hundreds or thousands of downstream organizations.

At the same time, organizations are managing vast, interconnected ecosystems of partners. Each additional vendor expands the attack surface and introduces new pathways for breaches.

This combination of growing dependency and rising threat activity is at the core of today’s Trust Crisis.

Traditional Vendor Due Diligence Continues to Fall Short

Despite the scale of this challenge, many organizations still rely on fragmented approaches to third-party risk management.

Questionnaires, self-attestations, and inconsistent assurance reports remain common. These methods often fail to provide meaningful visibility into a third party’s actual security posture.

As a result, organizations struggle to distinguish between partners that are truly secure and those that simply appear compliant.

This lack of reliable, comparable assurance creates inefficiencies, low confidence, increased costs, and unnecessary friction across vendor ecosystems.

In other words, the issue is not just risk. It is trust.

The Shift Toward Measurable Cybersecurity Assurance

The 2026 HITRUST Trust Report underscores a critical shift in how leading organizations must approach third-party risk. They should be moving away from compliance-driven models and toward assurance mechanisms that are:

• Standardized
• Defensible
• Independently validated
• Aligned to real-world threats
• Reduce duplicative assessments
• Improve visibility into supply chain risk
• Make faster, more confident risk decisions
• Focus resources on the highest-risk vendors
• Prescriptive and aligned to real-world attack techniques
• Independently validated through centralized quality review
•  Continuously updated to reflect emerging threats   

This shift is driven by the need for measurable cybersecurity outcomes, not just documentation.

The Report shows a stark contrast between traditional approaches and validated assurance models. In 2025, 99.62% of HITRUST-certified environments did not report a security breach, demonstrating measurable cybersecurity risk reduction.

By comparison, more than 40% of organizations report experiencing a breach.

That gap highlights an important reality. Assurance quality directly impacts security outcomes.

Building a Stronger Foundation for TPRM

Effective third-party risk management now depends on assurance that is consistent, comparable, and decision-ready.

Standardized and independently validated frameworks enable organizations to evaluate vendor security posture using reliable data, rather than subjective interpretations.

This approach addresses one of the most difficult challenges in cybersecurity today: managing risk across hundreds or even thousands of external vendors, each with varying levels of security maturity and transparency.

It also enables organizations to:

Importantly, assurance must extend beyond the organization itself. It must include the risks introduced by service providers.

The Report notes that over 80% of HITRUST certifications, including 100% of r2 certifications, address threats posed by an organization’s service providers.

This level of coverage is critical in a threat landscape where third-party exposure continues to grow.

Moving From Trust Assumptions to Trust Evidence

Trust has become a strategic requirement for digital business relationships. But it is increasingly difficult to establish.

Stakeholders including boards of directors, regulators, insurers, and investors are demanding proof that cyber risk is being effectively managed.

That proof cannot come from self-attestation or flexible interpretations of controls. It must come from assurance that is:

This is the foundation of modern TPRM.

It transforms assurance from a compliance exercise into a mechanism for measurable risk reduction and scalable trust.

The Future of Third-Party Risk Management

As organizations deepen their reliance on third parties and adopt technologies like artificial intelligence, the need for reliable assurance will only increase.

Traditional models are no longer sufficient for the scale, speed, and complexity of modern ecosystems.

Restoring trust requires a new approach. One that aligns assurance with real-world threats and measurable outcomes.

Because in today’s environment, trust can no longer be implied. It must be demonstrated.
