What are the biggest threats facing your organisation in 2026? How are security leaders responding to AI-powered attacks, geopolitical instability and an insider risk landscape that no one wants to talk about?

 

This in-depth, 26-page report draws on exclusive polling and panel discussion from teissLondon2026, the leading European summit for senior IT security professionals, held in February 2026 in London. Drawing on the knowledge of Europe’s leading CISOs, Heads of Security and C-Suite executives, the findings reflect how the most senior security practitioners are thinking right now.

 

What the report covers:

• AI on both sides of the firewall - how security teams are deploying AI defensively while confronting AI-assisted phishing, automated reconnaissance and governance gaps they didn’t anticipate
• Geopolitics as a security variable - why nation-state activity, supply chain dependencies and critical infrastructure exposure are now board-level conversations, with 91 per cent of delegates saying their organisation has been affected by geopolitical tension
• Ransomware in 2026 - how automation and emerging techniques are changing the extortion calculus
• The human factor - insider risk, burnout (88 per cent of teams affected) and a recruitment process 70 per cent of leaders believe is broken
• Leadership under pressure - governance, investment decisions and how CISOs are managing a role that 56 per cent say spans four to five full-time responsibilities, and 39 per cent say spans six or more

What you’ll learn:

• Where your organisation’s AI adoption and governance stands against 241 of your peers
• How to translate geopolitical risk into practical board-level reporting
• Why burnout and hiring are now security risks, not HR ones, and what leading organisations are doing differently
• What 55 per cent of organisations using AI cyber-defence tools have found about their maturity, and where the gaps still are
