Ryan Seymour, Vice President of Consulting and Education at ConnectSecure, challenges a fundamental assumption driving vulnerability management programs across the MSP industry in an article for MSSP Alert.
Most teams still lead with CVSS scores, addressing critical readings first, but Seymour argues that this approach reverses risk priorities. With 48,185 new CVEs published in 2025, MSPs juggling multiple client environments are drowning in alert volume, treating every “critical” flaw equally.
Instead of racing vulnerability scores, Seymour classifies assets into tiers based on their role in the business. Customer-facing infrastructure and payment platforms sit at the top tier, followed by email and file servers, with workstations and lab systems further down. Exploit likelihood is layered in afterward using EPSS and CISA’s KEV catalog, turning raw vulnerability data into a prioritization model that scales across client environments and holds up under scrutiny.
As Seymour notes in the article, this shift transforms client conversations. Instead of explaining CVSS scores, MSPs can explain business risk. A medium-severity vulnerability on a public authentication portal moves ahead of a critical finding on an isolated dev server because the business context demands it.
