A study conducted during Infosecurity Europe 2026 has found that AI-powered attacks at scale are the biggest security concern facing many cybersecurity professionals. The survey of 168 cybersecurity leaders across various sectors conducted by Filigran during the three-day event found 41% cited AI-powered attacks as a top challenge, double that of those who cited supply chain risk (21%) or unknown threats (21%). The research also asked what wastes most time within the security teams. Chasing false positives and low priority alerts the most common issue at 26%, suggesting significant proportion of time is spent validating findings. A further 25% cited validating whether risks are real, while 17% said manually stitching together data from multiple security tools and 13% pointed to delays waiting for other teams to act on findings.
