TL;DR: Runtime security splits into two materially different models, with eBPF telemetry serving as a lens for detection and LSM-based kernel enforcement serving as a shield that blocks malicious syscalls before they complete, according to AccuKnox. The distinction matters because observability alone cannot prevent fast-moving container escapes, prompt injection abuse, or AI workload compromise, and prevention now depends on inline control.
Editorial analysis by NHI Mgmt Group, based on content published by AccuKnox: “Zero Trust Runtime Security: The Non-Negotiable for the AI Age”.
Key questions
Q: What breaks when runtime security is only telemetry and not enforcement?
A: When runtime security stops at telemetry, the platform can detect suspicious behaviour but not prevent it.
Q: Why do kernel-level controls matter for fast-moving workload attacks?
A: Kernel-level controls matter because they sit on the path that executes the action.
Q: How should security teams decide which vulnerabilities need runtime blocking first?
A: Prioritise vulnerabilities that can turn untrusted input into immediate execution, network access, or privilege-changing behavior.
Practitioner guidance
- Differentiate telemetry from enforcement in procurement Require vendors to prove whether they only observe runtime behaviour or can deny unsafe syscalls in kernel space.
- Map runtime policies to workload behaviour Define expected process trees, file paths, and outbound destinations for each high-risk workload, then enforce those expectations with default-deny rules.
- Prioritise CVEs by live reachability Use runtime evidence to separate loaded, reachable, and exploitable vulnerabilities from dormant findings.
Bottom line: Runtime security splits into two different controls, and only kernel enforcement changes what the workload is allowed to do.

Runtime security is now a control problem, not a visibility problem. The article shows that the industry has blurred telemetry and enforcement into the same label, but those are different governance outcomes. Visibility helps teams understand risk, yet only inline control changes what the workload is actually allowed to do. For practitioners, that means runtime architecture should be judged by whether it can fail closed.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How can security teams keep AI workloads from becoming an execution path?
A: Security teams should constrain AI workloads with process, file, and network allowlists so model interaction cannot spill into arbitrary execution. The key is to treat the AI runtime as a privileged boundary, not a general-purpose environment. If the workload can reach credentials, APIs, or shell-like actions without inline policy, the risk is already operational.
