LLMs, Quantum Computing, and the Top Challenges for CISOs in 2026
Cybersecurity in 2026 is entering its most transformative and volatile phase yet. For CISOs, the landscape is no longer defined only by web, network, and cloud threats. Instead, attackers now target AI/LLM systems, APIs, identity platforms, SaaS ecosystems and supply chains. The surge in attacks across applications, APIs, and GenAI systems indicates that adversaries are scaling faster, using automation, AI-assisted exploitation, and new social engineering vectors.
