Also: Leadership Decisions Shaping Cybersecurity in 2026
Security leaders are heading into 2026 facing growing pressure from artificial intelligence-driven risks, limited resources and an increasingly complex threat landscape. Sean D. Mack, who leads ISMG’s CXO Advisor practice, joined ISMG editors to discuss how these forces are reshaping cybersecurity priorities for mid-sized organizations and enterprise leaders.

“Every security tool now is an AI security tool, like it or not,” Mack said. “A lot of these mid-sized businesses don’t have their AI policies in place, don’t have the governance in place that the larger companies have.”
Mack warned that without clear strategy and leadership, organizations risk reactive incident response and overlapping tools – rather than addressing foundational gaps in security. Security leaders, Mack said, need to prioritize fundamentals, culture and alignment between security and the business.
“Avoid that desire to take action for the sake of taking action, and take action in the right direction,” Mack said.
Mack joined Anna Delaney, executive director of productions; Tom Field, senior vice president of editorial; and Chris Riotta, managing editor of GovInfoSecurity, to discuss:
- How AI is reshaping cybersecurity for small and mid-sized businesses, emerging risks such as shadow AI and data leakage, and the need to prioritize core security fundamentals with limited budgets and staffing;
- How the rise of AI is accelerating and reshaping the role of fractional security leaders, who must focus on aligning cybersecurity with business strategy, driving execution and helping organizations cope with growing threats without a full-time CISO;
- Where security leaders are most likely to misread risk in the year ahead, the dangers of reactive decision-making and tool sprawl, and why building relationships and security culture matters more than chasing new technology.
