Securing AI agent data: checklist before you start

An AI agent can follow up on your unpaid invoices, sort your quote requests or prepare your customer responses. To do this, it needs to read your documents: invoices, contact details, exchange history. The question naturally arises: where does this data go, who can see it, and how can you retrieve or delete it? These are legitimate questions, and answering them before you start avoids unpleasant surprises.

IWhy verify security before entrusting your documents

A small business owner who creates an overdue payment recovery agent will send it customer names, amounts owed, sometimes addresses. This information is valuable and protected by law. If it leaks or is used for other purposes, your responsibility is engaged. Checking a few points beforehand takes an hour, no more, and allows you to work with peace of mind.

IIThe seven points of the security checklist

1. 1
   Where is the data stored

   Ask where the servers are located: in France, in Europe, elsewhere. Hosting in the European Union guarantees GDPR compliance. If the servers are in the United States, verify that a legal framework exists.

2. 2
   Who has access to it

   Read the privacy policy. Are your documents accessible to the service provider's technical teams? Are they used to train other systems? A clear answer must be included in the terms of service.

3. 3
   How is data encrypted

   Encryption protects your files during transfer and storage. Verify that the service provider uses standard encryption, both at rest and in transit.

4. 4
   How long are they retained

   A retention period must be specified. After deletion of your account or agent, your data must disappear within a reasonable timeframe, from a few days to a few weeks.

5. 5
   How to delete them

   You must be able to request deletion of your documents at any time. The process must be simple: a button, an email, a written procedure.

6. 6
   Are they shared with third parties

   Some services use subcontractors for processing. Verify who these third parties are and whether your data is transmitted to them.

7. 7
   Are there activity logs

   A log of the agent's actions allows you to know what it did, when, and with which documents. This is useful for monitoring and for proving your due diligence in case of questions.

IIINever give passwords in plain text

An AI agent does not need your password to work. If it needs to access an external service, this is done through an API key or secure connection, never through a password copied into a document. If you are tempted to write your password in the agent's instructions, stop: there is always another method.

IVAnonymize sensitive data when possible

Let's take the example of an overdue payment recovery agent. You send it a file with the names of late-paying customers, amounts, and dates. If you test the agent before putting it into service, you can use fictional data: invented names, rounded amounts. Once the operation is validated, you move to real data. This precaution limits exposure during the adjustment phase.

VCheck the terms and conditions in five minutes

Terms of service are often lengthy. Look directly for sections on "personal data," "confidentiality," "data processing," and "deletion." Four questions are enough: is my data used to train the system? Can I delete it at any time? Where is it hosted? Who has access to it? If the answers are vague or missing, ask for clarification in writing before you start.

Without verificationWith the checklist

You don't know where your invoices are stored

You know that hosting is in France

You do not know who can read your documents

You have read the privacy policy

You cannot prove your due diligence

You have a GDPR data processing agreement

You risk losing your data without recourse

You know the deletion procedure

VIExample: preparing a late payment recovery agent

Imagine you run a consulting firm and want to automate the follow-up of your unpaid invoices. Before creating the agent, you check the seven points on the checklist. You find that the service provider hosts the data in France, that your documents are not used to train other systems, and that you can request their deletion at any time. You prepare a test file with fictional names to validate the operation. Once satisfied, you move to real data, giving the agent access only to your follow-up email inbox, not your entire messaging.

VIIWhat to do if the service provider doesn't respond clearly

If you ask a question about security and the answer is vague, insist. A serious service provider must be able to tell you where your data is, who has access to it, and how to delete it. The absence of an answer is a warning sign. It's better to choose a transparent service, even if it's a bit more expensive, than to entrust your information to a black box.

• I verified where the data is hosted
• I have read the privacy policy
• I know how to delete my documents
• I did not provide any password in plain text
• I limited API permissions to what is strictly necessary
• I tested with fictional data before moving to real data
• I have a contract or terms of service compliant with GDPR

Check what applies to you: the list remembers your answers on this device.

?Questions we're asked

Can an AI agent read all my files without my consent?

No. You choose which documents to send to the agent. It can only access what you explicitly give it. If you connect an external service, you define the permissions granted.

Can my data be used to train other systems?

It depends on the service provider. Read the terms of service to verify. Some services commit to not using your data for training, others do not. Choose with full knowledge.

How do you know if a service provider complies with GDPR?

Request the data processing agreement required by GDPR. A compliant service provider must be able to provide it to you. Also verify that hosting is in the European Union or in a country recognized as offering equivalent protection.

Can I delete my data at any time?

A serious service provider allows you to request deletion of your documents whenever you wish. The procedure must be described in the terms of service or privacy policy.

Do you need a lawyer to verify the security of an AI agent?

Not necessarily. The seven points in this checklist cover the essentials. If you process very sensitive data (health, banking data), legal advice may be useful, but for most common uses, the checklist is sufficient.
