TL;DR: Kernel-level eBPF gives AI agent teams fast, low-overhead enforcement for syscalls, file access, and network connections, but ARMO argues it cannot see the prompt, tool call, or causal chain behind those actions. The practical issue is not visibility alone, but whether security controls can understand non-deterministic agent behaviour well enough to avoid false positives and blind spots.
NHIMG editorial — based on content published by ARMO: eBPF for AI Agent Enforcement: What Kernel-Level Security Catches (and What It Misses)
By the numbers:
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, sharing sensitive data, and revealing credentials.
Questions worth separating out
Q: What breaks when eBPF policies are applied directly to AI agents?
A: Static eBPF policies break because AI agents are non-deterministic.
Q: Why do AI agents make non-human identity governance harder?
A: AI agents make governance harder because they can request tools, act autonomously, and change behaviour across sessions while still relying on machine credentials.
Q: How do security teams know whether eBPF is actually protecting AI workloads?
A: They should look for correlation between kernel events and application context.
Practitioner guidance
- Define agent-specific enforcement tiers Classify each AI agent by data sensitivity, tool access, and acceptable behavioural variance, then assign a separate policy tier instead of reusing web-server TracingPolicies.
- Add application-layer telemetry above eBPF Instrument tool calls, L7 traffic, and execution chains so that kernel events can be correlated with the prompt or task that caused them.
- Limit runtime identities to task-scoped privileges Constrain service accounts, API tokens, and database roles so an injected prompt cannot expand the agent beyond its intended workflow.

Kernel enforcement is necessary, but it is not an AI security control by itself. eBPF gives defenders precise system-level visibility and fast denial capability, but AI agents fail in the semantic layer where prompt, tool, and data context determine whether the action is safe. That means a control stack built only on kernel observation will always be one layer late when the threat originates in agent reasoning. Practitioners should treat eBPF as the enforcement floor, not the governance model.
A question worth separating out:
Q: What should teams do when a prompt can change an AI agent's behaviour?
A: Teams should treat the prompt as an input to a privileged runtime, not as harmless text. If a prompt can alter tool choice, task scope, or execution timing, then it needs the same kind of control thinking applied to secrets, access paths, and approval gates. That is the point where AI security becomes identity governance.
