In our conversations with companies, we increasingly hear the same sentence: “We have already built our own AI agent.” Agent builders now integrated into office software make that possible. A few clicks, a short description, a folder as a knowledge source, and the agent is ready.

This is a positive development. Teams experiment, learn and reduce recurring work. The important question is what goes into those agents. Often it is precisely the information that needs special protection: customer enquiries with names and addresses, quotations with commercial terms, complaints, personnel records or contracts. AI privacy risks therefore often arise from how the tool is used.

This article explains what to consider when your team uses AI agents with sensitive information.

## Why an AI agent goes beyond a chat

In a regular AI chat, you ask a question and receive an answer. An agent goes further. It has persistent instructions, ongoing access to stored documents, mailboxes or file repositories, and may carry out tasks partly autonomously. It can also be shared with colleagues.

That makes agents useful and calls for greater care. Whether stored knowledge sources are available to every user depends on the permissions model. Check this before sharing the agent. Actions an agent can trigger may also happen without anyone reviewing them first.

## Seven tips for safer AI agents at work

### 1. Decide which data is allowed first

Before building an agent, decide what data it may work with. A simple classification into public, internal, confidential and particularly sensitive information is useful. Public and internal information is often less critical. Confidential customer information needs clear rules. Special categories of personal data under Article 9 GDPR, such as employees’ health information, should not go into an agent set up without an appropriate review.

### 2. Give the agent only what it needs

The GDPR requires data minimisation, which also makes practical sense for AI agents. An agent drafting quotations needs your price list and standard wording, but not the entire customer history. Connect the specific folders needed for its task rather than whole drives or mailboxes. Use placeholders instead of real names wherever possible.

### 3. Check permissions before connecting sources

Many agents access information using the permissions of the person using or creating them. That sounds reassuring. In practice, file repositories have often grown over many years. Folders may have been shared with everyone in the company and then forgotten. An agent can find those files and suddenly make them easy to search. Review access before connecting knowledge sources. Remember that sharing an agent can also make its knowledge available to others.

### 4. Clarify contracts, locations and data use

If a provider processes personal data on your behalf, you need a data processing agreement under Article 28 GDPR. Check where data is processed and stored, whether inputs are used to train AI models and when data is deleted. Pay attention to the licence: terms for an enterprise product do not automatically apply to private or free accounts that employees may also be using.

### 5. Keep approval with people

A good agent prepares; a person decides. This matters particularly for outgoing emails, bookings, orders and changes to your systems. Another risk is easy to overlook: text in emails, attachments or websites can contain hidden instructions that steer an agent towards unwanted actions. This is called prompt injection. An important additional safeguard is a simple rule: the agent may propose an action, but must obtain approval before carrying it out.

### 6. Write down rules and train your team

A short internal AI policy can be more useful than a blanket ban. It sets out who may build agents, which data is allowed and who reviews new agents before they are shared. Your team also needs to understand the rules and why they exist. Since February 2025, Article 4 of the EU AI Act has required providers and deployers to take measures to ensure sufficient AI literacy among their staff. Training on safe agent use can contribute to this.

### 7. Keep an inventory of agents

Agents are created quickly and can be forgotten just as quickly. Maintain a simple overview: which agents exist, who is responsible, what they are used for and which sources they access. Include AI applications processing personal data in your records of processing activities where required. Review whether agents are still needed, especially when employees leave.

## If sensitive data is already in an agent

Many companies read this advice after their first agents are already running. That is a good reason to take stock. Identify existing agents and the data they contain. Remove unnecessary knowledge sources and restrict sharing. Involve your data protection officer early. They can also assess whether a personal data breach has occurred and whether notification to the supervisory authority is required within 72 hours of becoming aware of it.

## How LIVOI handles your data

These experiences informed how we built LIVOI. Each company receives its own isolated LIVOI environment. Within it, you define who may see which processes and documents.

We set up specific connections to your systems, such as mailboxes, file repositories, ERP or accounting. You decide what AI may read and which actions it may trigger. Our agents prepare results such as extracted invoice information, draft replies or summaries. Your employees review, correct and approve them. Each step is traceable in the processing history.

LIVOI is developed and operated in Germany. The application and its persistent data stores are hosted in a German data centre: documents and attachments, conversation histories, the prepared knowledge base and agent configuration. Stored data is encrypted using AES-256. Companies wanting to keep the platform in-house can also run LIVOI on their own infrastructure.

For its answers, LIVOI uses selectable AI models and is not tied to a single provider. Depending on the function and configuration, connected AI services receive requests, conversation context, relevant knowledge excerpts or attachments. Document preparation and embeddings may also involve external services. Where processing takes place depends on the selected service and region. We agree that configuration with you during setup. The same applies to system connections: for each integration, we check where data flows.

We do not use your data to train AI models. Your documents, conversations and expertise remain your property and serve to handle your requests. We also conclude a GDPR data processing agreement with each customer. We review the selected model provider’s terms together during setup.

Our [documentation on data flows and data locations](https://livoi.de/docs/about/data-flow-and-data-location/) describes these paths. You and your data protection officer can review them before starting the first agent.

Before an agent is created, our potential analysis establishes which data is involved, which workflows are suitable and where boundaries make sense. No prior AI knowledge is necessary. We explain each step so everyone involved understands what happens to their data. Find out more about the platform on our [LIVOI page](https://p-cation.de/en/livoi/).

## Safety depends on how agents are used

AI agents can be useful tools for your team. Clear decisions about allowed data, access and final approval help make their use safer. Practical rules, reviewed permissions and a platform that keeps you in control provide a sound basis for daily work.
