Prompt Shields

Open source. Self-hosted. European.

AI governance belongs in your tenant.

So we gave the toolkit away. Run the SDK, the gateway and the agent controls inside your own cloud account — see what every model call costs, block what should never be sent, and keep every agent accounted for, without routing your prompts through anyone else first.

Runs where you do
Your own Azure, AWS or GCP account, or your own hardware. Containers and compose files, not a sales call.
Nothing has to leave
Self-host in an EU region and prompts, logs and keys stay inside it. Sovereignty by deployment, not by promise.
Yours to audit
Apache 2.0 and MIT. Read the code, fork it, and keep running it if we stop being useful.

Built in Norway and the UK. Run it yourself, or let us host it in the EU.

  • 40+ years shipping secure software
  • 100+ CIOs & CISOs interviewed
  • Backed by Innovation Norway & Microsoft for Startups
  • Trusted by a leading Nordic insurer

Where it runs

Your cloud account. Your region. Your keys.

Everything in the toolkit ships as containers with a compose file. Deploy it into the subscription you already have, and the prompts, the logs and the provider keys stay inside your own boundary.

That is what turns sovereignty from a contract clause into a deployment detail. If the data never leaves your tenant, there is no transfer left to argue about with your regulator.

Your own cloud account

Azure, AWS or GCP, in the subscription and region you already run. Atlas AI, the SDK and the agent shield each ship a compose file.

Your own hardware

On-premises or air-gapped, when a cloud account is not the answer. The same containers, no phone-home.

An EU region, hosted by us

If you would rather not operate it, we run it for you in Europe — the managed option, not the only option.

A laptop, first

docker compose up, and the collector is running locally. Try it on real traffic before anyone deploys anything.

Built in Norway and the UK. Controls are mapped to the EU AI Act, DORA, NIS2, GDPR, the NIST AI RMF and ISO 42001, so the evidence comes out in the shape an auditor already expects.

The gateway

Every model call through one route, and the route is yours

Point your code at a gateway running in your own account and every request from every team passes somewhere you control. That is the point at which you can see what is being spent, enforce what is allowed, and send each task to a model that is good enough for it.

Model vendors are paid by the token, so nobody selling you one has a reason to send your work somewhere cheaper. Putting a gateway in front of them makes that your decision instead.

Connects to what you already run

Your SIEM, GRC and ITSM tools plug in as connectors, and anything else goes through the SDK. Nothing has to be replaced for the gateway to see the traffic.

Atlas AI spend dashboard showing total spend, actual versus estimated cost and savings recommendations

Usage and cost in one place

Spend by vendor, by model and by team, measured against what was estimated, so an unexpected invoice becomes a line you can point at rather than a surprise.

Atlas AI savings recommendations, including routing low-complexity tasks to a cheaper model and right-sizing a token commitment

The cheap wins, found and priced

Most traffic is classification and extraction that a smaller model handles for a fraction of the price. Atlas finds that work, prices the swap, and shows what the change is worth — the decision, and the switch, stay yours.

Atlas AI policy enforcement dashboard showing strict and loose policy counts, coverage, blocks over 30 days and a violations chart

Policy enforced where AI is used

Start in guideline mode and watch what would have been blocked. Promote a rule to strict once you trust the false-positive rate, not before.

Atlas AI top policies by hits, showing enforcing rules that block prompt-injection attempts and redact personal data in AI prompts

Sensitive data stopped before it leaves

Prompts are inspected on the way out. Personal data is redacted and injection attempts are blocked, with every hit counted so you can see which rule is actually doing the work.

Atlas AI adoption and ROI view, showing quality-weighted measurement of how well AI is used

Evidence that any of it worked

Usage on its own proves nothing. Atlas weights it by whether the output survived, so the number you take to the board is what landed, not what was generated.

Agents

An agent holds your credentials and reads untrusted text all day

That is the whole attack. Text the agent reads becomes instructions the agent follows, and it is already authenticated as someone. Endpoint detection sees a legitimate process; the proxy sees an allowed egress; DLP sees an authorised read.

The tool call is the one place the intent is visible. So that is where the check belongs — and it runs in your tenant, next to the agent, not in somebody else's cloud.

Atlas AI Agent Discovery — a meta-agent sweep across AWS Bedrock AgentCore, Azure AI Foundry and GCP Knowledge Catalog, listing agents as registered, pending, shadow or residency risk

Find them across AWS, Azure and GCP

A meta-agent queries Bedrock AgentCore, Azure AI Foundry and the GCP Knowledge Catalog, then sorts what came back into registered, pending, shadow and residency risk — so an agent running in the wrong region is a flag, not a surprise.

Atlas AI Agents Control Panel — a fleet table showing each agent's cloud, control state, health, risk score, success rate, 30-day cost and lifecycle stage, with pause, quarantine and release actions

Pause or quarantine any one of them

Beta in Atlas AI

The whole fleet with its cloud, control state, health, risk score, 30-day cost and lifecycle stage, and the pause, quarantine and release actions next to each row.

Stop the injection at the tool call

OpenClaw Prompt Shield is a policy layer between a computer-use agent and the tools it invokes. Every shell command, file operation and network request is checked before it runs, with Azure Prompt Shield handling jailbreak and indirect-injection detection inside your own Azure tenant. Start in monitoring mode, and switch to enforcing once you have read what it would have blocked.

Watch the agents on the laptop

Agent Sentinel is the on-device half: an agent on a Mac holds credentials, reads files and calls the internet, and Sentinel shows what it did, governs what it can reach, and gives you a kill switch that works without a network round trip.

The repositories

Released so far, and free to run today

Components go out one at a time, each with a post explaining it. Everything listed here is public and licensed right now — nothing on this list is a promise.

We are plain about the commercial side, because a security company saying “it is all free” invites a fair question about what it sells. The code was never the hard part. What is hard to rebuild is the policy library that comes from running this in regulated places, the evidence an auditor accepts, and someone to call at 3am. If you can run it yourself, run it yourself — we would rather that than have you pay for something you do not need.

What Promptly does

One set of company knowledge, four ways to help

Connect your policies and documents once. Every kind of help Promptly gives draws on the same source, so the answer in the chat, the warning at the field and the nudge in the corner never disagree with each other.

When someone has a question

Ask

A chat that answers from your company's own AI policy, approved-tool list and documents, and names the source it used.

At the exact moment it matters

Tips on the spot

A small hint right where someone is typing. Customer data about to go into an external AI tool gets flagged, with a one-click way to remove it.

Before anyone thinks to ask

Nudges

An occasional suggestion for a better way to do the task in front of them: the approved tool, or a prompt that gets a usable answer first time. Rare, and easy to dismiss.

Early access

When the answer is a place on screen

Guide

Hold a key and ask out loud. A pointer moves to the right control and explains each step, in the app you already have open.

Usage overview

Which AI tools each team uses and where people get stuck, shown in aggregate.

On the desktop, not just the browser

Giving back

We took more from this community than we have given back

Every product we have built stands on work other people released for free. Open-sourcing the toolkit is part of paying that back, and so is everything else on this page.

Free tools

A prompt scorer, a PII anonymiser, an AI policy generator and a readiness assessment. No account, no trial, no upsell.
