Does runtime enforcement add latency to engineering work?

Evaluation happens on the action being attempted, not on the model's response, so the work it does is local pattern and context evaluation rather than a round trip to an AI service. The user-visible cost of a correct allow decision should be imperceptible; the visible cost is on warn and block, which is the intended behaviour.

Any client-side control can be uninstalled, and pretending otherwise is dishonest. What governance adds is that the absence becomes visible: coverage is measurable, and a machine that stops reporting is a fact an administrator can see and act on. Treat enforcement as raising the cost and the visibility of a bypass, not as making one impossible.

Is runtime governance the same as an AI firewall or an LLM gateway?

A gateway sits between an application and a model API and governs traffic it can see. That covers systems your organization builds. It does not cover an employee using a consumer AI product in a browser, or a coding agent acting locally in an IDE, because neither routes through your gateway. The approaches address different surfaces and are frequently deployed together.

What happens when a policy blocks something it should not have?

That case has to be designed for, not treated as an exception. The block should say which rule matched so the user understands it, an exception path should exist and be time-boxed, and the false positive should be visible in the same evidence stream as the true positives so the rule can be tuned.

Short answer

What is runtime AI governance, and how is it different from an AI policy document?

Runtime AI governance is enforcement that happens at the moment an AI-assisted action is attempted, rather than in a document read at onboarding or in a report produced weeks later. A control sits in the path of the action, reads the action and its context, evaluates organizational policy, and returns a decision: allow, warn or block. The distinguishing property is timing — the decision lands before the consequence, which is the only point at which a policy can still prevent something.

Definition

Runtime AI governance: Runtime AI governance is the enforcement of AI usage policy at the point of action, where each attempted action is evaluated in context and permitted, warned on, or blocked before it takes effect.

Diagram

Where the decision happens

The control is in the path, not beside it. A system that observes and reports occupies the same diagram with the arrow pointing only one way — and cannot change the outcome.

Step 1
Attempted action
A prompt submitted, a file written, a command run, a tool invoked.
Step 2
Context gathered
Which tool, which repository, which permission mode, what content, which user.
Step 3
Policy evaluated
Organizational rules applied to the action and its context.
Step 4
Decision recorded
The attempt, the rule that matched and the outcome are written down.

Possible outcomes

Allow
Nothing in the action matched a restrictive rule. It proceeds, and is logged.
Warn
The action is permitted but flagged to the user, who chooses whether to continue.
Block
The action does not take effect. The user is told which rule stopped it.

Detective, preventive, and why the difference is not academic

A detective control tells you something happened. A preventive control stops it happening. Both are legitimate, and most AI programs implement only the first because it is far easier: log the activity, review it later, follow up.

That works for anything reversible. It does not work for disclosure. Once a credential, a customer record or a proprietary algorithm has been transmitted to a third-party service, no later review undoes it. The remediation for a leaked secret is rotation, and rotation is expensive precisely because the disclosure cannot be taken back.

Runtime governance is the preventive half. It does not replace monitoring; it means that the subset of activity that is genuinely irreversible gets stopped rather than reported.

Why context matters more than content

Content inspection alone produces a control that is either too loose or unusable. A string that looks like an API key is sometimes an API key and sometimes an example in documentation. A command that deletes files is routine in a scratch directory and alarming in an infrastructure repository.

Context is what separates the two. The same proposed action can carry a different decision depending on the surface it happens on, the sensitivity of the repository it touches, the tool requesting it, and how much autonomy that tool is currently operating with.

Surface: a browser AI tool, an IDE, a coding agent, an autonomous execution loop.
Repository or workspace sensitivity, where the action touches code.
Permission mode: whether a human is confirming each step or the agent is running unattended.
Data classification of the content involved.
Whether the content originated from an untrusted source, such as fetched web content.

The false-positive budget is the real design constraint

Any enforcement control can be made strict enough to catch everything. The cost is that engineers route around it, and a control that is disabled or bypassed is worth less than no control, because it also produces false confidence.

This is why graded responses exist. Reserving blocks for the small set of actions that are both high-confidence and irreversible, and using warnings for everything ambiguous, keeps the control credible. A warning that a human can override is still governance: it creates a decision point, and it creates a record of the decision.

What Oconee Runtime does at this layer

Oconee Runtime implements this pattern across the surfaces it integrates with: a browser extension covering browser AI tools, and an IDE extension covering VS Code and its forks, including AI-assisted engineering activity. Detections cover categories such as credentials and API keys, regulated personal data, source code and secrets, and unsafe instruction patterns.

Policy tiers differ in what they can do. Detection and activity logging are present from the entry tier; allow, warn and block policy controls are a Growth-tier capability; command and file-mutation enforcement for AI-assisted engineering are Growth+ capabilities. The comparison on the pricing page is the authoritative statement of which tier includes what.

Examples

A prompt containing a private key is typed into a browser AI tool by an engineer working under deadline.
The content is evaluated at submit time. A credential match is high-confidence and the disclosure is irreversible, so this is one of the few cases that warrants a hard block rather than a warning.
An agent running unattended proposes a command that rewrites history on a shared branch.
The same command from an interactive session with a human confirming each step may be permitted. Run unattended, the permission mode changes the risk, and the action is escalated for confirmation or blocked.
A file in a repository marked sensitive is about to be modified by an AI-assisted edit.
Repository sensitivity, not the prompt, decides. The mutation triggers the policy attached to that repository, and the attempt is recorded either way.
