When a single vendor’s compromised credentials led to the largest healthcare breach in history, the vendor’s clients weren’t the ones who made headlines. Every organization that depended on them was. 30% of breaches now involve a third party, doubled from 15% the prior year (Verizon 2025 DBIR), and the financial, regulatory, and insurance consequences are landing on the organizations least prepared to absorb them. If your clients depend on vendors they haven’t assessed, they’re in that group.
For MSPs and MSSPs, the data points in two directions. First, your clients’ exposure to third-party risk is growing faster than their ability to manage it. Second, the combination of regulatory pressure, insurance requirements, and vendor sprawl creates a service opportunity that fits the managed services model. As insurers increasingly require third-party risk management (TPRM) and clients expect stronger vendor oversight, TPRM has become a natural recurring revenue opportunity for MSPs and MSSPs.
What follows are statistics across six categories: breach trends, financial impact, cyber insurance, regulatory pressure, vendor sprawl, and the market opportunity. Use them alongside our broader MSP cybersecurity statistics for client conversations, proposals, and internal business cases.
TL;DR
- Third-party breaches doubled year-over-year, now accounting for 30% of all confirmed breaches
- Third-party breaches cost $4.91 million on average, 11% above the global average
- Major cyber insurance carriers now require vendor risk assessments as a standard underwriting condition
- Organizations manage an average of 286 vendors but the average TPRM team is 8.5 people
- The vendor risk management market is projected to reach $51.34 billion by 2030
The Third-Party Breach Landscape
The 2024–2025 data shows third-party risk accelerating faster than most of your clients expected, and some industries carry disproportionate exposure.
Breach frequency is accelerating
The year-over-year numbers are the ones worth leading with in client conversations.
- 30% of breaches involved a third party in 2024, doubled from 15% the prior year (Verizon 2025 DBIR)
- 35.5% of breaches originated from third-party compromises, up 6.5% year-over-year (SecurityScorecard 2025 Global Third-Party Breach Report)
- 88% of SMB data breaches involve ransomware, and third-party access is a primary vector (Verizon 2025 DBIR)
That doubling from 15% to 30% reflects both increased targeting and expanded attack surfaces. Every vendor relationship your clients add is another potential entry point.
Some industries carry higher exposure
Third-party breach rates vary by sector, and those differences should shape which client conversations you prioritize.
- Retail and hospitality: 52.4% of breaches originated from third parties (SecurityScorecard)
- Energy and utilities: 46.7% from third parties (SecurityScorecard)
- Technology vendors enabled 46.75% of third-party breaches, down from a prior 75% estimate as risks broaden to non-tech services (SecurityScorecard)
- Healthcare saw 41% of 2024 breaches from third parties (Censinet/KLAS/AHA Healthcare Cybersecurity Benchmarking Study 2025), with costs averaging $9.77 million per incident (IBM/Ponemon Cost of a Data Breach 2024)
If you serve clients in retail, energy, or healthcare, third-party risk is the primary attack surface, not an adjacent concern. And when a breach does come through a vendor relationship, it costs more than most clients expect.
What Third-Party Breaches Cost
When a breach comes through a vendor, your clients pay more. Third-party breaches run above the global average, and the operational disruption extends well beyond the incident itself. The Change Healthcare case shows what happens when a single vendor failure cascades through an entire industry.
Direct costs exceed the global average
The cost premium reflects what makes these breaches harder to contain: multiple organizations involved, unclear ownership, and longer detection timelines.
- Third-party breaches cost an average of $4.91 million, the second costliest initial vector after malicious insiders at $4.92 million (IBM Cost of a Data Breach 2025)
- The global average breach cost is $4.44 million, making third-party breaches 11% above the mean (IBM 2025)
- The US average breach cost reached $10.22 million, a 9% increase (IBM 2025)
- Healthcare breaches average $7.42 million and financial services breaches average $6.08 million, both well above the global mean (IBM 2025)
- Breaches contained in under 200 days cost $1.14 million less (IBM 2025)
- Breaches involving data across multiple environments averaged $5.05 million, common in supply chain attacks (IBM 2025)
That $1.14 million difference between fast and slow containment connects directly to what your clients can control. Their ability to detect and respond to a vendor compromise affects the final cost more than almost any other variable.
Change Healthcare showed what cascading vendor failure looks like
The Change Healthcare breach is the clearest example of what happens when a critical vendor fails and the organizations that depend on it have no contingency plan.
- 190 million individuals affected in the largest healthcare data breach in history (HHS Breach Portal)
- Billions in direct costs to UnitedHealth Group (UHG SEC filings)
- Nine-day detection delay between initial access and ransomware deployment (HHS investigation)
- Claims processing for hundreds of thousands of healthcare providers disrupted for weeks
- Nearly two-thirds of physicians used personal funds to cover operational costs during the outage (AMA)
- Root cause: compromised Citrix credentials with no multi-factor authentication (MFA)
Small practices were hit hardest. Claims couldn’t be submitted, payments stalled, and some providers faced bankruptcy from a breach that happened inside a vendor they couldn’t control. Your clients need to understand that their security posture is only as strong as the vendors they depend on. That exposure is exactly what cyber insurers are now pricing into their policies.
Cyber Insurance Is Rewriting the Rules
Cyber insurers have become de facto regulators for third-party risk, and their requirements are reshaping how organizations approach vendor management.
Carriers now require vendor risk assessments
Vendor risk assessments have moved from “nice to have” to a standard underwriting requirement. Major carriers, including Coalition, Marsh, and Munich Re, now cite vendor risk management as a core underwriting factor. The trend is consistent across insurer reports:
- Vendor risk assessments are becoming standard requirements for policy issuance and renewal
- Carriers increasingly mandate annual or continuous vendor assessments, particularly for policies with higher limits
- Standardized questionnaires (SIG, CAIQ) are the most common format carriers accept for vendor risk documentation
- 49% of organizations experienced a third-party cybersecurity incident in the past year (Ncontracts 2025 TPRM Survey)
For your clients, insurance renewal is now a TPRM conversation whether they realize it or not. If you can help them prepare vendor risk documentation before renewal, you’re solving a problem they’ll encounter in the next 12 months.
Claims data shows third-party exposure
The claims data makes the insurer logic clear: third-party breaches are driving a disproportionate share of payouts. Multiple insurer reports confirm that supply chain and vendor-related incidents now represent a significant and growing share of cyber claims. The breach data supports this from the other direction:
- 30% of all confirmed breaches involved a third party in 2024, doubled from 15% the prior year (Verizon 2025 DBIR)
- 35.5% of breaches originated from third-party compromises (SecurityScorecard 2025)
- Third-party breaches cost $4.91 million on average, above the $4.44 million global mean (IBM 2025)
- 45% of organizations expect to face significant cyber-attacks on their supply chains (World Economic Forum, cited in Munich Re 2025)
TPRM maturity directly affects premiums and claim outcomes
The financial incentive is directionally clear, even where exact figures vary by carrier. Organizations with mature TPRM programs pay less for coverage and are less likely to have claims denied.
- Carriers consistently report that organizations without vendor risk programs face higher premiums and increased declination risk at renewal
- Organizations with continuous monitoring and documented vendor oversight are rewarded with more favorable terms
- Claims tied to third-party incidents face additional scrutiny, with insurers increasingly denying claims where vendor risk documentation is absent or incomplete
- 66% of financial institutions feel pressure to enhance TPRM programs, with nearly half citing auditors and regulators as the primary driver (Ncontracts 2025)
The direction is unambiguous: TPRM documentation directly affects whether your client’s insurance will pay out when they need it. That’s a concrete conversation you can have with any client approaching renewal. Insurance is one forcing function, and regulation is the other.
Regulatory Pressure Is Accelerating
Regulators are removing the ambiguity around vendor risk management. DORA and NIS2 in Europe are pushing TPRM requirements downstream, and organizations of every size are now in scope.
DORA and NIS2 are codifying vendor oversight
The EU’s Digital Operational Resilience Act (DORA) took effect in January 2025 for financial institutions, mandating third-party risk management as a core operational requirement, not a best practice. NIS2 extends similar obligations across the broader supply chain.
DORA requires financial entities to maintain a register of all ICT third-party providers, conduct risk assessments before outsourcing critical functions, and include specific contractual clauses covering incident reporting, audit rights, and exit strategies. Most financial institutions are still catching up. The regulation moved faster than their programs.
NIS2 adds supply chain mandates across a wider set of sectors:
- Supply chain security policies with supplier selection criteria, cybersecurity evaluations, and resilience analysis (Article 21)
- 24–72 hour incident reporting for incidents affecting supply chain operations
- Security clauses required in vendor contracts covering incident notification, audits, vulnerability management, training, and certifications
The compliance burden is compounding
The challenge for your clients extends beyond any single framework. Your clients are feeling the cumulative weight of multiple overlapping requirements.
- 66% of financial institutions feel pressure to enhance TPRM programs, with nearly half citing auditors and regulators as the primary driver (Ncontracts 2025 TPRM Survey)
For MSPs serving clients in financial services, healthcare, or defense, TPRM is a compliance requirement your clients need help meeting. And meeting that requirement starts with understanding the scale of the vendor ecosystem your clients are actually managing.
The Vendor Sprawl Problem
Your clients are working with more vendors than ever, assessing fewer of them, and managing the process with tools that were not built for the job. The gap between how many vendors they have and how many they actually monitor is where your service opportunity sits.
Vendor ecosystems are growing faster than oversight
The average organization’s vendor count has outpaced its ability to track, assess, and monitor those relationships.
- 286 vendors per company on average in 2025, a 21% increase year-over-year (Whistic 2025 TPRM Impact Report)
- 56% of companies manage 100+ vendors, up from 50% in 2024 (Whistic 2025)
- More than half of financial institutions oversee 300+ vendors, but 73% have two or fewer full-time employees managing vendor risk (Ncontracts 2025 TPRM Survey)
When financial institutions, organizations with regulatory mandates for vendor oversight, can’t staff the function, your SMB clients have no chance of doing it alone.
Assessment gaps are where the risk concentrates
The gap between how many vendors organizations have and how many they actually assess is where breaches happen. A vendor risk assessment questionnaire is the baseline, and most organizations are not even clearing it.
- 49% of organizations experienced a third-party cybersecurity incident in the past year (Ncontracts 2025 TPRM Survey)
- The average vendor responds to 37.3 assessment requests monthly, up from 29.5 the prior year. The demand for documentation is outpacing the capacity to produce it (Whistic 2025)
Capacity, not technology, is the constraint
The shift from spreadsheets to dedicated platforms is underway, but staffing hasn’t kept pace with the tools.
- 73% of financial institutions have two or fewer full-time employees managing vendor risk, even though more than half oversee 300+ vendors (Ncontracts 2025 TPRM Survey)
- The average TPRM team is 8.5 people, with 75% of teams under 10. Each team member is responsible for assessing roughly 34 vendors (Whistic 2025 TPRM Impact Report)
- AI ranks as the second-biggest TPRM risk heading into 2025, with institutions increasingly adding AI-specific criteria to vendor assessments (Ncontracts 2025)
When 73% of financial institutions have two or fewer people managing vendor risk across 300+ vendors, the constraint is capacity, not technology. That is where your services fit.
The TPRM Market Opportunity
Your clients’ organizations are investing in TPRM, and the growth trajectory favors service providers who can deliver it. The market data backs up what the breach, insurance, and regulatory numbers already showed.
Market growth is accelerating
- Risk analytics market projected to grow from $32.25 billion to $51.34 billion by 2030, a CAGR of 9.7% (MarketsandMarkets)
- TPRM tools expected to grow at the highest CAGR among software types in the 2025–2030 forecast (MarketsandMarkets)
- GRC spending increasing 35%+ over the next two years (MarketsandMarkets)
For MSPs, the relevant number is the TPRM tools growth rate. When TPRM-specific tools lead the category in projected growth, the vendors selling to your clients are going to expect vendor risk documentation as standard practice.
Your clients need the service but will not build it internally
The data consistently shows that smaller organizations recognize the need but lack the resources to address it. Nearly half experienced a third-party cybersecurity incident in the past year (Ncontracts 2025), and AI is emerging as a new dimension of vendor risk that most organizations haven’t yet addressed. Meanwhile, insurance carriers are increasingly denying claims where vendor risk documentation is absent.
Your clients are not going to build an internal TPRM function. The question is whether their MSP offers it or whether nobody does.
Turning Data Into Client Conversations
The throughline across these statistics is that third-party risk has moved from a security concern to a business requirement. Insurers require vendor assessments, regulators mandate supply chain oversight, and breach costs run 11% above the global average when a vendor is involved. Meanwhile, your clients manage nearly 300 vendors on average with a team of fewer than 10 people.
Every number in this piece maps to a specific client conversation. The insurance data arms you for renewal discussions, the regulatory stats support compliance gap assessments, and the breach costs make the ROI case for proactive monitoring. The vendor sprawl data shows clients the scale of what they are not currently managing.
For MSPs building TPRM into their service portfolio, platforms like Cynomi provide the structured methodology and automated assessments to deliver vendor risk management at scale across your client base.
