Gigamon, a leader in deep observability, has released its 2026 Hybrid Cloud Security Survey, revealing a fundamental shift in the cyberthreat landscape. AI is now involved in 83% of reported security breaches, enabling attackers to operate with greater speed and scale than many organisations can defend against.
Despite expanded investments in tools and governance policies, 65% of organisations experienced a breach in the past year, reflecting an increase of 40% over the past three years. The findings highlight a growing imbalance as adversaries leverage AI to accelerate cyberattacks, while defenders are constrained by fragmented visibility into what’s happening across their networks.
“AI is embedded in nearly every stage of the attack chain, enabling adversaries to outpace detection and response,” said Shane Buckley, President and CEO at Gigamon. “While 93% of organisations are investing in new security tools, many still lack visibility into how data moves across their environments, creating confidence without control. Closing this gap requires deep observability, giving security teams the clarity needed to detect threats earlier and respond with precision.”
The annual study, now in its fourth year, surveyed more than 1,000 global security and IT leaders across Australia, France, Germany, Singapore, the UK and the US. The survey report, Reality Check: Exposing the AI Security Illusion, explores the disconnect between confidence and reality, revealing a critical blind spot in how organisations assess AI-driven risk.
