After Mythos: Building Vulnerability Resilience
About this Whitepaper
Anthropic's Claude Mythos Preview and OpenAI's GPT-5.5 are not isolated events. They signal a structural shift: AI is now capable of finding and validating exploits faster than most enterprise security programs can respond. Mandiant's M-Trends 2026 data shows exploitation is now arriving before patches exist. Conventional vulnerability management programs were never built for this.
This whitepaper, written by Sunil Gottumukkala, Founder and CEO of Averlon, explains why patch-first programs break under this pressure and what a resilient operating model looks like.
- -7 days mean time to exploit in 2025, down from 63 days in 2018-2019, meaning exploits now arrive before patches exist (Mandiant M-Trends 2026)
- 184M assets had open KEV exposure at day 28 in 2025, up from 31M in 2022 (Verizon DBIR)
- 252 days average time to remediation in 2025, up from 171 days in 2020 (Veracode)
The whitepaper covers the shift to exposure-led VulnOps (also referred to as RemOps), managing the no-patch window with runtime controls, supplier and OSS risk in an AI-accelerated environment, and a 90-day CISO action plan with board-level resilience metrics.
