How Large Organizations Navigate AI and Cybersecurity in 2026
The Wavestone Cyber Benchmark 2026 reveals a steady acceleration in global cybersecurity maturity, heavily driven by stringent regulatory pressures and the rapid integration of artificial intelligence. While traditional defenses and incident response frameworks have significantly strengthened, critical vulnerabilities remain in systemic cyber resilience and the technical safeguarding of AI technologies. To maintain a strategic advantage in this evolving landscape, organizations must urgently bridge the gap between their robust executive governance and their glaring blind spots in automated recovery and AI threat mitigation.
Points clés
- Wavestone analyzed over 200 companies, including more than 100 large organizations with turnovers exceeding $1 billion and a combined workforce of over 7 million employees.
- The overall cybersecurity maturity of large organizations reached 55.3/100, with the highly regulated financial sector aggressively leading the market at a score of 67.6.
- Cybersecurity budgets within large organizations average 7.8% of the total IT budget, marking a noticeable increase from 6.4% in 2025.
- The average ratio of security Full-Time Equivalents (FTE) to total employees is now 1 for every 1,016 employees, though the financial sector boasts a much stronger 1/199 ratio.
- While 58% of large organizations display sufficient maturity against ransomware, 25% of medium-sized entities remain in a highly critical and vulnerable state.
- Across the NIST Cybersecurity Framework, the “Recover” pillar lags significantly at 44% maturity, indicating widespread underinvestment in true business resilience.
- Detection capabilities saw a 5% growth driven by SOC maturity and AI integration, while 50% of organizations now have cybersecurity directly supervised by their Executive Committee.
- Artificial Intelligence security remains a dangerously nascent field with an overall maturity of only 38%, and a mere 10% of organizations possess technical defenses against malicious prompts.
- Large organizations currently score 60/100 in NIS 2 compliance, hampered by the fragmented regulatory transpositions across Europe and complex legacy asset management.
À retenir
If you are running a business today, congratulations: your executive team finally cares about cybersecurity, mostly because regulators are currently breathing down your neck. But before you pop the champagne for hiring that one security expert for every thousand employees, you might want to learn how to actually recover from an attack instead of just watching it burn your servers down. Oh, and those fancy new AI tools you just rolled out? You should probably put a lock on them, because leaving the front door wide open to hackers with a clever chat prompt isn’t exactly a winning corporate strategy.
