What March Proved

A board-level strategic briefing synthesizing the three defining risk patterns of March 2026. First: cyber operations are inseparable from geopolitical conflict — the medical technology wiper that destroyed 80,000 devices through weaponized endpoint management demonstrated that trusted infrastructure can become the attack vector. Second: the developer supply chain is the new critical infrastructure — the TeamPCP cascade spread across six platforms from a single compromised vulnerability scanner. Third: AI is creating attack surface faster than organizations can secure it — AI platforms were exploited within hours of disclosure. The World Economic Forum reports 91% of large organizations have changed cybersecurity strategies due to geopolitical volatility, and 87% of leaders see AI vulnerabilities as the fastest-growing cyber risk. This edition provides four board-level questions for Q2 2026 planning.
