CSO Online, Monday, June 1st, 2026
CISOs must close six strategic gaps in perception, speed, skills, AI security, and legacy systems to build resilience.
The article identifies six priority gaps CISOs must address: shifting from protecting IT systems to ensuring business resilience; closing the speed gap with threat actors; matching security to business velocity; updating skills, especially in AI; securing AI deployments with proper governance; and modernizing exploitable legacy infrastructure.
Research shows one-third of surveyed CISOs believe their data isn't adequately protected, while 58% report being unprepared for cyberattacks.
Experts emphasize reframing security's role, adopting automation and AI tools, upskilling across the organization, and prioritizing modernization investments based on risk assessment.
