Use AI without sending the wrong data

Names, emails, and other private details can end up in the messages your team sends to AI. Guarrix checks what goes in and what comes back, so nothing slips through by accident.

The problem

Every message you send to AI can carry more than you meant to share.

Your AI should not see everything

Your team pastes real information into AI tools every day — names, emails, ID numbers, customer details. Once it's sent, it's gone. You can't call it back.

There is another problem

Someone can hide instructions inside normal-looking text, trying to make your AI ignore its own rules or reveal something it shouldn't. It's hard to catch by hand, and it only takes one message to get through.

You don't know what actually left

Without a check in place, you usually hear about a problem from a customer, not from your own systems. Nothing is watching what goes out the door.

Why teams trust Guarrix

Three things that matter when you're sending data to AI.

Built in Europe

Guarrix is Dutch, not American. There's no US parent company and no CLOUD Act exposure — your data stays under EU law.

We also check what comes back

It's not just what you send. Guarrix checks the AI's reply too, before it reaches your users.

Your messages are not our business

The checking happens on our servers in Europe. Content is processed in memory and thrown away right after — never logged, never used to train anything.

What does Guarrix protect you from?

Everything you need to run this in production, not just try it out.

Personal data doesn't slip through

Guarrix checks every message for names, emails, ID numbers and other private details before they reach your AI provider.

Your AI can't be tricked into breaking its own rules

People can hide instructions inside normal-looking text. Guarrix checks for that too, on the way in and on the way out.

You can prove what happened

Every request is logged — what was found, what action was taken, how long it took — without ever storing the message itself.

Keep the AI provider you already use

OpenAI, Anthropic, Mistral, or any OpenAI-compatible endpoint. Guarrix sits in front of it, so you can switch providers later without changing your protection.

One dashboard, nothing extra to run

Manage your rules, your API keys and your billing from a single place. No new infrastructure, no separate service to maintain.

What are the alternatives?

There are different ways to make AI safer. You can build the protection yourself, use tools from your AI provider, or use a service made specifically to protect AI applications. The best choice depends on what you are building and how much you want to manage yourself.

Alternative	Where Guarrix differs
AWS Bedrock Guardrails	AWS lock-in, US jurisdiction, enterprise pricing, inbound checks only — Guarrix is EU-jurisdiction, bidirectional, and provider-agnostic.
Protecto / Nightfall	US companies with CLOUD Act exposure — Guarrix is a Dutch company operating entirely under EU law.
LiteLLM (open source)	Requires self-hosting and setup, no managed service, no dashboard, no outbound scanning — Guarrix is a managed service covering both directions out of the box.
Anonify.nl	Document redaction only, not a full AI gateway — Guarrix sits in front of your LLM calls end-to-end.
Lakera Guard	Strong attack-focused security platform aimed at enterprise buyers — Guarrix is a simpler, EU-hosted guardrail layer for apps you've already built.
Protect AI	Broader tooling across AI development and infrastructure security — Guarrix is scoped specifically to the request/response layer in front of your LLM calls.

Build it yourself

You can build your own checks into your app. This gives you full control, but you also have to build, test and maintain everything yourself. As new risks appear, your protection needs to change with them. This can work well if you have the time and people to manage it.

Guarrix does this work for you, so your team can focus on your app.

Use the protection from your AI provider

Some AI providers include their own safety tools. They can be useful, but your protection can become connected to that provider. If you change AI providers later, you may also have to change how you protect your app.

Guarrix keeps the protection separate. You can choose the AI provider that works best for you and change providers later without starting over.

Only remove private data

You can add rules that remove names, email addresses and other private information before sending something to AI. That solves one part of the problem. But private data is not the only risk. Someone may try to trick your AI into ignoring its rules. The AI itself can also return something you do not want your users to see.

Guarrix checks both what goes in and what comes back.

How does Guarrix compare?

Guarrix is not the only product that helps companies use AI more safely. Different products are built for different needs. Here is a simple overview to help you compare them.

Guarrix

Guarrix is made for businesses that want a simple protection layer between their app and their AI provider. Your messages are checked in Europe and the full content is not stored. You can keep using your own AI provider and change providers without replacing Guarrix.

Lakera Guard

Lakera Guard is an established AI security product with a strong focus on protecting AI applications from attacks. It can be a good fit for organizations looking for a larger AI security platform and enterprise security features.

Protect AI

Protect AI offers a broader set of tools for securing AI systems. It can be a good choice for organizations that want security across more parts of their AI development and infrastructure.

Why choose Guarrix?

We don't believe one product is the right choice for everyone. Guarrix is built around a few simple ideas:

Keep your AI provider — switch providers whenever you want, without replacing your protection.
Keep your messages private — the full content is never stored, only metadata.
Keep your data in Europe — the checking itself runs on our servers under EU law.
Protect both directions — what you send and what the AI sends back.
Start small — try the sandbox free, no signup, then add a plan when you're ready.

The goal is simple: give your AI an extra safety check without making your application more complicated.
