TL;DR: Traditional cybersecurity misses AI systems because they are probabilistic, autonomous workflows that can hide shadow deployments, data poisoning, drift, and prompt injection, according to Orca Security. In regulated sectors, AI governance now depends on continuous visibility, scoped access, and framework-aligned controls rather than periodic reviews.
Editorial analysis by NHI Mgmt Group, based on content published by Orca Security: “AI Security Best Practices for Regulated Industries”.
By the numbers:
- According to Gartner, 80% of enterprise applications shipped or updated in Q1 2026 embed at least one AI agent, up from 33% in 2024.
Key questions
Q: What breaks when AI governance is only a one-time review?
A: A one-time review breaks as soon as the agent gains a new tool, a new dataset, or a new workflow.
Q: Why do agentic AI systems increase risk for API security and governance?
A: Agentic AI increases risk because it can interpret context, make decisions, and execute multi-step actions without waiting for direct human approval.
Q: How can organisations tell whether their AI security model is actually working?
A: They should test whether the control stack can explain who acted, what data was touched, and what purpose the action served.
Practitioner guidance
- Discover shadow AI continuously Inventory every model, embedded AI feature, third-party LLM connection, and automated workflow across cloud estates, then keep the inventory current as new deployments appear.
- Classify regulated data before it reaches AI Map PHI, PII, financial records, and other sensitive data through training, fine-tuning, and inference paths so policy can stop unauthorised use.
- Scope agent credentials to explicit workflows Assign each AI agent least-privilege access, avoid shared service accounts, and define the data sources and external systems it can call.
Bottom line: AI security in regulated sectors fails when teams treat models like static applications instead of dynamic actors that can touch data, tools, and workflows after deployment.

Continuous AI posture control is now a governance requirement, not a monitoring enhancement. Regulated sectors cannot rely on periodic snapshots when the subject being governed changes behaviour during runtime and can touch data, tools, and infrastructure in one session. The practical conclusion is that AI oversight must be continuous enough to keep evidence current for both security teams and auditors.
A few things that frame the scale:
- Organisations that describe themselves as confident in their AI deployment actually experience a 72% security incident rate, compared to 33% for those who remain cautious, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How should organisations align AI governance with both the EU AI Act and NIST AI RMF?
A: Organisations should treat the EU AI Act as the mandatory compliance baseline and the NIST AI RMF as the operational framework that turns governance into repeatable controls. The practical move is to map AI use cases, assess risk, assign ownership, document safeguards, and maintain evidence for audits. That combination helps teams satisfy regulatory obligations while building a defensible AI governance programme.
