The next major breach to hit your clients likely won’t come from behind your walls. It can be delivered through a vendor they trust, a SaaS tool contracted by their finance team, or a subcontractor that no one in IT knows about. This is a new attack surface, and most organizations are ill-prepared for it.
Cynomi’s new guide, Securing the Modern Perimeter: The Rise of Third-Party Risk Management, argues that TPRM is no longer a form of compliance. This is a front-line security challenge and a critical growth opportunity for MSPs and MSSPs getting ahead of it.
Expanding modern borders
For decades, cybersecurity strategies have revolved around defined boundaries. Firewalls, endpoint controls, and identity management systems were deployed to protect assets within known boundaries.
Those boundaries have melted away.
Client data currently resides in third-party SaaS applications, flows through vendor APIs, and is processed by subcontractors that your internal IT team may not know about. Security is no longer just about owned infrastructure. It extends across an interconnected ecosystem of external providers and the accountability that comes with it.
The 2025 Verizon Data Breach Investigations Report found that 30% of breaches involve third parties. IBM’s 2025 Cost of Data Breach Report puts the average cost of remediating a third-party breach at $4.91 million. Exposure to third parties is no longer a special case; it has become a core feature of modern business operations.
For proactive service providers, this shift creates significant opportunities. Organizations facing growing third-party threats are seeking strategic partners who can own, streamline, and continuously manage the entire third-party risk lifecycle. Service providers who step into this role can introduce new services, offer higher-value consulting, and position themselves as the focal point of their clients’ security and compliance programs.
From checkboxes to core risk features
Traditional approaches to vendor risk rely on annual surveys, spreadsheets, and occasional follow-up emails. It’s never been enough and it’s especially expensive now.
Regulatory frameworks such as CMMC, NIS2, and DORA have significantly raised the bar. Achieving compliance requires continuous monitoring of third-party controls, rather than a point-in-time snapshot from 12 months ago. Boards are asking tougher questions about vendor exposure. Cyber insurance companies scrutinize supply chain hygiene before writing policies. And customers who have watched competitors absorb the impact of vendor breaches understand that “it wasn’t our system” does not limit liability.
The market is reacting accordingly. Global TPRM spending is projected to increase from $8.3 billion in 2024 to $18.7 billion by 2030. Organizations treat vendor monitoring as a governance function on par with incident response and identity management. Because the cost of ignoring it has become too high.
For service providers, that budget allocation is a clear signal. Clients are actively seeking partners who can own and manage vendor monitoring as a defined, ongoing service.
Scaling TPRM is where most providers get stuck
Most MSPs and MSSPs recognize this opportunity. A source of hesitation is whether delivery, and TPRM in particular, can be performed profitably at scale.
Traditional vendor reviews rely on fragmented workflows and manual analysis. Custom assessments must be sent, tracked, and interpreted, and risks must be stratified according to each client’s specific obligations. This work is often done by senior consultants, making it expensive and difficult to delegate.
Multiplying this effort across a client portfolio with different vendor ecosystems, compliance needs, and risk tolerances can be unsustainable. For this reason, many providers offer TPRM as a one-time project rather than a regular managed service.
But there are also opportunities. Cynomi’s Securing the Modern Perimeter guide outlines how structured, technology-enabled TPRM can move from bespoke consulting engagements to repeatable, high-margin service lines that enhance customer retention, drive upsells, and position service providers as essential partners in their customers’ security programs.
Turn TPRM into a revenue source
Third-party risk is an endless conversation starter.
Every time a client brings a new vendor on board, a discussion about potential risks arises. Regulatory updates are a valid reason to review vendor programs, and any violations traced back to third parties in the news further increase the risk. TPRM works well and can be integrated into the client’s strategy rather than relegating the service provider to reactive support, and its positioning completely changes the nature of the relationship.
Providers who build structured TPRM capabilities realize that it opens the door to the following possibilities:
Broader security advisory work Higher retainer value Stronger customer relationships built on real business impact Differentiation in a crowded managed services market Trusted third-party risk governance, demonstrating maturity to future customers
conclusion
Third-party risk persists. The vendor ecosystem that clients rely on will become increasingly complex with more SaaS platforms, AI-powered tools, subcontractors, and regulatory oversight. Organizations that manage this risk well will reap significant benefits in resilience and compliance.
Building a structured, scalable TPRM practice that provides consistent oversight across your portfolio will have a far greater impact than adding headcount or assembling a bespoke program for each client from scratch. Once you build the infrastructure, it benefits all accounts.
