The 2025 Verizon Data Breach Investigations Report (DBIR) reveals a concerning shift in cybersecurity threats. While ransomware and zero-day exploits continue to make headlines, two underlying factors are increasingly fueling successful breaches: third-party exposure and machine credential abuse.
## Third-Party Risk Doubles in One Year
Third-party involvement in breaches has doubled year-over-year, jumping from 15% to 30%. Today’s enterprises rely on a complex network of contractors, vendors, business partners, and service providers, creating sprawling identity ecosystems that are difficult to secure. Without proper governance, these non-employee identities become prime targets for attackers.
The problem spans all sectors, with healthcare, finance, manufacturing, and government all reporting major incidents stemming from third-party access. Poor lifecycle management—such as contractor accounts remaining active after project completion or business partners having excessive privileges—often enables these breaches.
## Machine Identities: The Rapidly Growing Threat
While human identities remain vulnerable, machine identities present an even faster-growing risk. Service accounts, bots, RPAs, AI agents, and APIs are multiplying rapidly, often without clear ownership or oversight. The 2025 DBIR found that credential-based attacks remain a primary access method, with attackers increasingly targeting ungoverned machine accounts.
As AI adoption accelerates, machine identity growth—and complexity—will only increase, making this vulnerability more critical. Yet most traditional identity security tools still treat machine identities as secondary concerns.
## The Need for Unified Identity Governance
Managing employees, third-party users, and machine identities in separate silos creates dangerous security gaps. Attackers don’t need to breach everything—they just need one opening. The report shows that breaches tied to third-party users and machine accounts are accelerating faster than those involving internal employees.
Organizations must recognize that all identities—human, non-employee, or machine—require consistent governance under a unified strategy. This approach closes critical gaps, improves visibility, and strengthens defenses across the entire identity ecosystem.
The message is clear: fragmented identity governance is no longer just a weakness—it’s a liability. As the gap between human and machine identity security widens, organizations must implement comprehensive solutions before attackers exploit these vulnerabilities.
