The next major breach hitting your clients probably won’t come from inside their walls. It’ll come through a vendor they trust, a SaaS tool their finance team signed up for, or a subcontractor nobody in IT knows about. That’s the new attack surface, and most organizations are underprepared for it.
Cynomi’s new guide, Securing the Modern Perimeter: The Rise of Third-Party Risk Management, makes the case that TPRM is no longer a compliance formality. It’s a frontline security challenge and a defining growth opportunity for MSPs and MSSPs who get ahead of it.
The Modern Perimeter Has Expanded
For decades, cybersecurity strategy revolved around a defined perimeter. Firewalls, endpoint controls, and identity management systems were deployed to protect assets within a known boundary.
That boundary has dissolved.
Today, client data lives in third-party SaaS applications, flows through vendor APIs, and is processed by subcontractors that internal IT teams may not even know about. Security no longer stops at owned infrastructure. It extends across an interconnected ecosystem of external providers, and the accountability that comes with it extends there, too.
The 2025 Verizon Data Breach Investigations Report found that third parties are involved in 30% of breaches. IBM’s 2025 Cost of a Data Breach Report puts the average remediation cost of a third-party breach at $4.91 million. Third-party exposure has become a core feature of modern business operations, not an edge case.
For proactive service providers, this shift creates a substantial opportunity. Organizations facing mounting third-party threats are looking for strategic partners who can own, streamline, and continuously manage the entire third-party risk lifecycle. Service providers who step into that role can introduce new service offerings, deliver higher-value consulting, and establish themselves as central to their clients’ security and compliance programs.
