What happened
Cisco CEO Chuck Robbins told the Q4 earnings call that Anthropic's Mythos bug-finding model is driving a network refresh 'supercycle,' as customers rush to replace unsupported (past LDOS) networking equipment they now consider too risky to operate. Robbins said buyers are pulling from security budgets to fund replacements, and cited quantum-readiness and AI network demands as the other two factors. Cisco reported $17.3B Q4 revenue (up 17%) and $63.3B for the year (up 12%).
Why it matters
If AI bug-finding models like Mythos are systematically surfacing vulnerabilities in unsupported hardware and software, any builder running past-end-of-life infrastructure (routers, switches, firewalls, even old library versions) faces a shrinking window before those flaws become public. Audit your stack for components past their last support date and budget for replacement now—before a model finds the bug for you.
Discussion angle
Does AI-driven vulnerability discovery change the calculus on running unsupported open-source dependencies or end-of-life cloud instances, and how should small teams without Cisco-level budgets prioritize what to replace first?
