[Previously](https://jetstream.security/insights/a-policy-is-not-a-control/) : a JetStream AI Blueprint™ is the design you approved. This installment: proof that the running system still matches it, captured as it happens.* Ask most organizations how AI is being used, and whether that use aligns with internal policies and frameworks, and you will commonly see a scramble ensue. Three people on a bridge, pulling logs that were never designed to answer the question, reconstructing after the fact what an agent did on a Tuesday in April. I was recently in this room and it was very uncomfortable. Attestation, the annual scramble, is not evidence. Evidence is a property of the system while it runs, or it does not exist. The [anchor of this series](https://jetstream.security/insights/audit-the-evidence-ai-policy/) said the standards stopped accepting the promise that a control exists and started asking you to show that it operated. Runtime is where this can be demonstrated and proven. ## Govern the decisions, not the models Most AI-related issues are caused by what an agent did that it wasn’t supposed to. The agent executed its workflow: the command ran, the data was read, the tools were called, and records changed. Runtime Governance watches decisions and actions, not the artifacts. What was decided, what was accessed, what was invoked, what changed. If your monitoring is aimed at the model and not at the actions, you’re missing key information in the process. ## What “continuous” actually means Three areas matter most, and each maps to something that standards require. Live behavior is compared against the approved design, continuously. Drift is what to watch out for here. A prompt shifts, a tool is added, a permission widens, a model is swapped, all with no code deploy and no ticket. You catch drift by comparing live behavior to [the design of record from the last installment](https://jetstream.security/insights/a-policy-is-not-a-control/) . A workflow is approved. If any change occurs from that approved flow, personnel are automatically notified and enforcement action can be taken programmatically. Activity is logged without cherry-picking. The record has to be the record. When a change surfaces, someone with authority approves it or the run stops. That is the workflow-approval step, and it is what turns “we noticed drift” into “we did something about it, and here is who.” Which brings up the control everyone asks about. ## The kill switch, described honestly You need to be able to stop an agent and its actions immediately and selectively. The standards are more specific about this than most people realize. NIST is direct about it: its Manage function calls for mechanisms to supersede, disengage, or deactivate an AI system that shows performance or outcomes inconsistent with its intended use (MANAGE 2.4). ISO/IEC 42001 does not name a stop button, but it gets there through operational control (Clause 8) and its nonconformity and corrective-action duties (Clause 10), which assume you can bring a misbehaving system under control. The EU AI Act is the most explicit of the three: its human-oversight article requires that a person be able to intervene in a high-risk system or interrupt it through a stop button or a similar procedure that brings the system to a halt in a safe state (Article 14(4)(e)), and to decide not to use the system or to disregard or override its output (Article 14(4)(d)). So this is not a control you are adding on your own initiative. **Exhibit: the kill switch, framework by framework.** | Framework | What it demands: a stop or kill capability | Provision | | --- | --- | --- | | NIST AI RMF | Mechanisms to supersede, disengage, or deactivate a system operating outside its intended use | MANAGE 2.4 | | ISO/IEC 42001 | Operational control, and the duty to correct a nonconforming system | Clauses 8 and 10 | | EU AI Act | A person can interrupt a high-risk system and bring it to a halt in a safe state | Article 14(4)(e) | Turning a system off is reversible: once you have resolved the issue, you turn it back on. What you cannot do, and what nobody should promise, is un-take an action the agent already took. A sent message was sent. A deleted row is gone. That is why the kill switch is only half the control. The other half is blast radius. Least privilege, and short-lived, scoped credentials, so that in the window between an agent going wrong and you stopping it, the damage it was able to do is small. You do not prevent every bad action. You make the bad action survivable, and then you stop the next one. ## Where the standards put this ISO/IEC 42001 puts operation and performance evaluation in Clauses 8 and 9: you operate the AI system under control, and you check that it is doing what the management system says. The EU AI Act, for high-risk systems, requires human oversight (Article 14), accuracy, robustness, and cybersecurity that hold up in the real world (Article 15), and post-market monitoring after deployment (Article 72), which is the Act’s plain way of saying the watching does not stop at launch. NIST’s Measure and Manage functions are the same instinct: measure behavior in production and manage what you find. Here is what the runtime controls look like as an exhibit: the runtime action, the requirement it answers, and the test that produces it. **Exhibit: from runtime control to standard.** | Runtime control | NIST AI RMF | EU AI Act | ISO/IEC 42001 | JetStream test | | --- | --- | --- | --- | --- | | Block destructive code-execution commands | MEASURE 2.7 (with MANAGE 4.1) | Art. 15 | A.6.2.6, A.9.2, Clause 8 | Destructive code-execution commands are redacted or blocked | | Redact or block PII in prompts and outputs | MEASURE 2.10 (with MAP 1.6) | Arts. 10, 15 | A.7.4, A.4.3, Clause 6.1.4 | PII (credit card, IBAN, SSN, tax ID) is redacted or blocked | | Detect and block prompt injection | MEASURE 2.7 | Arts. 15, 55 | A.6.2.6, A.6.2.4, A.9.2 | Prompt injection is detected and blocked | | Redact or block leaked secrets and credentials | MEASURE 2.7 | Art. 15 | A.4.3, A.6.2.6, Clause 8 | Leaked secrets and credentials are redacted or blocked | | Halt or disengage a system operating outside its approved bounds | MANAGE 2.4 | Art. 14(4)(e) (stop / safe halt) | Clause 8, Clause 10 | A run can be stopped and safely re-enabled | Each one of those is a single runtime action that both reduces a risk and leaves a logged, attributable record. ## Fast because it is continuous If every action is checked against the approved design as it happens, you do not need a committee to reconvene before a change ships. You approve fast because you approve continuously. Your senior leaders have likely been asking for a runtime control plane, not another dashboard. Dashboards tell you what happened and a control plane does something about it. Leaders who own the AI program have been trying to prove that production actually matches policy, which is exactly what continuous assurance produces: not a document that says the system is fine, but a live record that shows it. ## What audit-readiness really is Audit-readiness is not a binder you assemble the week before a big audit. It is a property you either have on any given afternoon, or you do not. If someone asked you today to show that every AI system in production has stayed inside its approved boundaries since it went live, could you produce it when asked, or would you be scrambling to formulate a response? The programs that answer “now” are not the ones with more people. They are the ones that decided evidence is something you capture as it happens, not something you reconstruct once a year. Runtime is where that decision gets made, or gets deferred. *Next installment: runtime evidence is only defensible if every action ties back to someone. Next, who owns it.* ## Stay ahead with our newsletter Stay informed on industry trends, expert analysis, and product updates. #### Explore more insights [See all Insights](/insights) [https://jetstream.security/insights/ai-agent-security-containment-approvals/](https://jetstream.security/insights/ai-agent-security-containment-approvals/) AI Advisory Sep 3, 2026 ###### Treat Your AI Agent Like an Attacker What fifteen years of chasing lateral movement taught me about AI agents, and the 1990s cockpit research that explains why a human in the loop only helps if the… [https://jetstream.security/insights/ai-agent-security-containment-approvals/](https://jetstream.security/insights/ai-agent-security-containment-approvals/) [https://jetstream.security/insights/ai-security-control-plane-beyond-gateway/](https://jetstream.security/insights/ai-security-control-plane-beyond-gateway/) AI Advisory Aug 27, 2026 ###### An AI Gateway Is Insufficient Security Without a Control Plane Somewhere in your estate, an agent you approved is doing something you did not intend.
