Beyond the “Ban”: Why AI-SPM + Runtime Firewalls are the New Standard for AI Security

For many organisations, the first reaction to Shadow AI was a blanket ban. But as we move into 2026, it is clear that blocking ChatGPT doesn’t stop the need for efficiency, it just drives it underground.

The real challenge isn’t the AI itself; it is the lack of visibility and the unprotected prompts that lead to data leaks and security breaches.

The “Solid” Control Measure: The Two-Layer Defence

Modern security leaders are moving towards a combined approach that pairs AI Security Posture Management (AI-SPM) with AI Runtime Firewalls.

1. AI-SPM (The “Eyes”): This provides a continuous inventory of every AI model, SaaS tool, and API in your environment. It identifies misconfigured models and “shadow” tools that bypass IT, giving you a clear map of your actual attack surface.
2. AI Runtime Firewalls (The “Shield”): While AI-SPM finds the tools, the Firewall secures the usage. It intercepts prompts in real-time to block Prompt Injection attacks and prevent sensitive data (like PII or source code) from being uploaded to public models.

The Bottom Line

Shadow AI isn’t a “blocking” problem; it is a governance opportunity. By implementing a posture-plus-protection strategy, organisations can empower employees to innovate with AI while keeping their most sensitive data behind a secure, monitored perimeter.
