TL;DR: Extending visibility and policy controls across browsers, desktop apps, APIs, and MCP-connected AI workflows, including real-time detection of prompt injection, data leakage, and shadow AI use, SentinelOne says its definitive agreement to acquire Prompt Security will do so. The deal underscores that governing employee AI use now requires runtime inspection, not policy documents alone.
Editorial analysis by NHI Mgmt Group, based on content published by SentinelOne: “A New Chapter for AI and Cybersecurity: SentinelOne Acquires Prompt Security”.
Key questions
Q: What breaks when AI governance only documents policy and does not inspect runtime activity?
A: Policy-only governance leaves a blind spot at the point where AI systems actually process prompts, route data, and trigger actions.
Q: Why do MCP and AI tool workflows increase API security risk?
A: They increase risk because the model or agent becomes an active caller that can move across tools and data sources within one flow.
Q: How should security teams govern shadow AI without blocking productivity?
A: Use visibility-based controls instead of blanket bans.
Practitioner guidance
- Map AI interaction paths to governed access points Inventory browsers, desktop tools, APIs, IDE assistants, terminal copilots, and MCP-linked workflows as distinct control paths rather than a single AI channel.
- Enforce runtime inspection for sensitive prompts Inspect prompts, responses, and attached context in real time so redaction, blocking, or tokenisation happens before data leaves the protected boundary.
- Review MCP connector permissions as privileged integrations Treat each connected server or tool as a delegated access relationship and validate what actions the AI layer can initiate on the organisation's behalf.
Bottom line: AI governance now depends on runtime inspection of prompts, responses, and tool calls, not on policy documents alone.

Runtime AI governance is becoming the new access control layer. Policy documents and app allow lists cannot govern what employees do once prompts, files, and connectors are in motion. The relevant control point is the interaction itself, where sensitive data can be entered, transformed, or forwarded. Practitioners should treat AI sessions as governed access events, not as informal productivity tools.
A few things that frame the scale:
- 53% of security leaders expect AI to run major portions of their infrastructure autonomously within the next three years, according to the 2026 Infrastructure Identity Survey.
- Half of companies using generative AI will deploy agentic AI by 2027, according to Deloitte's 2025 Technology Predictions.
A question worth separating out:
Q: What is the difference between role-based access control and AI-assisted access governance?
A: Role-based access control assigns permissions through predefined roles. AI-assisted access governance evaluates whether a specific entitlement still makes sense using usage patterns, peer behavior, and risk context. RBAC standardizes access, while AI helps decide whether that access is still justified in a changing environment.
