The adoption-security gap
85% of enterprises use AI tools, but only 23% have AI-specific security controls. This gap is the defining challenge of enterprise security in 2026. Organizations are flying blind — shadow AI proliferates, sensitive data flows to AI providers, and there is no audit trail to assess the damage.
Emerging threats
- Sophisticated prompt injection — Multi-step, encoded, and context-switching injection attacks evade basic filters
- AI supply chain attacks — Malicious AI plugins, poisoned model weights, and compromised RAG data sources
- AI-assisted social engineering — Deepfakes, voice cloning, and AI-generated phishing at enterprise scale
- Regulatory enforcement — EU AI Act enforcement actions beginning August 2026
Recommendations
- Deploy prompt-level inspection for immediate data protection
- Discover and classify shadow AI across the organization
- Establish AI governance with automated enforcement and audit trails
- Integrate AI security into existing SOC operations
- Prepare for regulatory compliance requirements

Frequently asked questions
How prevalent is enterprise AI adoption?+
By 2026, 85% of enterprise organizations have adopted AI tools in some form. However, only 23% have implemented dedicated AI security controls. This gap — widespread adoption with limited security — defines the current threat landscape.
What is the most common AI security incident?+
Sensitive data exposure through AI prompts accounts for approximately 60% of AI security incidents. This includes PII, source code, credentials, and internal documents shared with third-party AI providers without security controls.
What should CISOs prioritize for AI security?+
Three immediate priorities: (1) Deploy prompt-level inspection for real-time data protection, (2) Discover shadow AI across the organization, and (3) Establish basic AI governance with audit trails. These three controls address 80% of enterprise AI risk.
