Cybersecurity leaders have never had the luxury of moving slowly, but the second half of 2026 may test even the most mature security teams. AI is accelerating both sides of the fight: Attackers can find vulnerabilities, craft more convincing scams and move faster, while businesses (and employees) are racing to embed AI into products, workflows and everyday operations. That combination raises the stakes for every leader responsible for protecting data, systems, customers and trust.The challenge isn’t just technical. As cyber risk spreads across engineering, finance, operations, legal, HR, procurement and executive teams, the old model of security as a separate checkpoint no longer fits how businesses actually run. The organizations that handle this next phase successfully will need to rethink cybersecurity as a shared operating discipline, not a last-minute review, compliance exercise, or problem for one department or leader to solve alone.Members of the Senior Executive Cybersecurity Think Tank have deep expertise in enterprise cybersecurity strategies, risk management, threat detection and cybersecurity leadership. Below, a group of them discusses what they see as the biggest cybersecurity challenges for leaders in the second half of 2026 and how organizations move from reactive defense to enterprisewide resilience.
