The Cost Of Delayed Patching: What Security Teams Are Missing
Cyber Defense Magazine, Monday, July 13th, 2026
Exploitation now precedes patch availability, making delayed patching a board-level business risk rather than a backlog problem.
Mandiant M-Trends 2026 puts mean time-to-exploit at roughly 7 days, meaning exploitation typically precedes patch availability, versus a 63-day buffer in 2018, while defenders take about 14 days to remediate half of CISA KEV entries.
Costs stack up across breach likelihood (vulnerability exploitation was the initial vector in about 20% of 2025 breaches, 60% with a patch already available), direct exposure (IBM's $4.88 million average), ransomware amplification (about a third of attacks), and hidden operational drag.
Roughly 81% of CIOs and CISOs admit deliberately delaying patches to protect operations.
The three structural misses are prioritizing by CVSS instead of exploitability, treating patching as periodic, and coverage gaps across hybrid estates.
