For online merchants, marketplaces, and retailers
DataBait injects undetectable fictitious user accounts into your customer files (CRM, customer accounts, marketing database, loyalty programme, databases shared with your routing providers, your marketplaces, and your service providers), each with a real email address and a mobile number, monitored 24/7. Since these accounts match no real customer, any email, SMS, or call they receive reveals illegitimate use of your data and produces court-admissible proof, within 72 hours.
The cost of a data leak
Online merchants make their customer file their most valuable asset, and their most externalised one: they share it with routing providers, ad networks, marketplaces, carriers, and agencies. It is now the number one target of financially motivated attacks, with attackers moving away from payment data in favour of customer data, which is easier to resell; and the share of leaks that pass through a third party keeps growing.

Data security
DataBait detects the actual theft of your data through its use, once it has left your information system.
Your EDR and DLP watch access and the perimeter of your information system; once the data has gone out to your email and SMS routing providers, your ad networks, your marketplaces, your carriers, your agencies, and your SaaS providers, they are blind to what is done with it. E-commerce is the industry that externalises its customer data the most: every provider is a legitimate exit route for your file, and just as many misappropriation surfaces beyond the reach of your perimeter tools. DataBait takes over on use: since the fictitious accounts it injects match no real customer, their only expected contacts are your own mailings and those of the senders you have declared; any other contact betrays, by construction, illegitimate use of your data. Complementing your existing setup, with no structural false positives.
Legal
DataBait provides you with court-admissible proof of the theft of your data: a commissaire de justice report, drawn up within 72 hours, sealed by a qualified eIDAS timestamp.
Each step of the procedure is sealed by a qualified eIDAS timestamp, issued by a QTSP on the EU Trusted List: contract signature, the list of fictitious accounts DataBait injected, source code of the emails and SMS received, through to the commissaire de justice report that consolidates them. Compliant with the AFNOR NF Z67-147 standard, this report is admissible before French courts.
For an online merchant, this report covers both an internal and an external leak: it establishes that a customer database left its perimeter, on what date, through which channel it was used, and with which forensic metadata. Your legal team holds proof already assembled to characterise the facts and decide on the steps to take, whether it concerns an employee bound by confidentiality or a provider operating outside the scope of its DPA. Without the report, those steps remain theoretical.
Compliance
DataBait supports your GDPR compliance: the alert, sealed by a qualified eIDAS timestamp, proves your date of awareness, the certain starting point of your notification to the CNIL.
The GDPR requires you to notify a breach to the CNIL within 72 hours (article 33) and, where the risk to your customers is high, to communicate it to them (article 34): a critical deadline in e-commerce, where a leak triggers mass notification and exposure to collective redress (class action). Beyond the deadline, the leak itself is documented: in an inspection or in litigation, you demonstrate what you knew, when, and what you did about it. And when a third party uses your database for unsolicited marketing, the report establishes the breach under the electronic marketing rules (article L.34-5 of the French Postal and Electronic Communications Code).
If you run an online marketplace, Directive (EU) 2022/2555 (NIS2) classifies you among the important entities (annex II, digital providers); its transposition into French law (the Résilience bill) will require a documented ICT risk management framework, a notification timeline to ANSSI (early warning within 24 hours, notification within 72 hours, final report within 1 month), and monitoring of your providers. DataBait tools these pillars: a documented detection capability, an incident dossier timestamped within 72 hours, and continuous monitoring of your providers, with no additional audit.
Use cases
DataBait detects and proves leaks and misuse of your customer files, whoever the actor.
A departing e-CRM or growth manager walks off with the customer file and exploits it, resells it, or takes it to a competitor. A fictitious account is contacted: you are alerted, and the report lets you bring disciplinary proceedings and criminal action.
An email routing provider, an agency, a marketplace, or an IT provider shared between several retailers reuses or leaks your file outside the DPA: exactly the vector of the 2024 serial leaks, where several retailers were hit through a common provider. Contact with a fictitious account reveals the misappropriation, backed by court-admissible proof.
An attacker steals your customer database and puts it up for sale on a forum. Your fictitious accounts surface on the dark web: you learn it from monitoring, not from your customers' complaints. You warn them of the phishing, fake after-sales service, and identity-theft risk, then notify the CNIL — before the press picks it up.
How it works
DataBait turns every attempt to misuse your customer files into proof.
DataBait injects undetectable fictitious user accounts into your customer files (CRM, customer accounts, order history, marketing and newsletter database, loyalty programme, databases shared with your routing providers, ad networks, marketplaces, carriers, agencies, and SaaS providers), generated from public statistical datasets (INSEE, IRIS, BDNB), with no LLM and no hallucination, each carrying a real email address and a mobile number.
Email address and mobile number monitored continuously; since these accounts match no real customer and your own senders are declared, any other contact received is illegitimate by construction, with no structural false positives.
Continuous search for your fictitious accounts across forums, marketplaces, and dumps, even with no contact at all: you know a database has leaked before the CNIL or the press.
Every signal generates proof sealed by a qualified eIDAS timestamp and triggers an alert qualified by type, enriched with OSINT and delivered with its forensic metadata, so your teams can prioritise (email or SIEM integration).
Commissaire de justice report compliant with the AFNOR NF Z67-147 standard and a qualified eIDAS timestamp, court-admissible within 72 hours, directly usable for your GDPR notification and your claims.
Integration
DataBait is a fully managed SaaS: it runs with no agent and no change to your infrastructure, with no impact on your storefront or your conversion rate, and carries no operational overhead for you; every alert is a real signal, with no false positives to triage.
Alerts reach you through the channel of your choice: email (the primary channel, precisely addressable per recipient and per project) or SIEM integration. No agent to install, no schema migration: the fictitious accounts are injected through the same import routes as your new customers or your campaigns.
Protecting the merchant
DataBait injects the fictitious accounts into your CRM, your marketing database, your loyalty programme, and your customer accounts. You tool your own compliance (GDPR, and NIS2 if you run a marketplace) without changing your information system, and without touching your payment data.
Third-party oversight
DataBait injects fictitious accounts dedicated to each database you share with your email and SMS routing providers, your ad networks, your marketplaces, your carriers, your agencies, and your SaaS providers. Segmented by recipient, these databases make it possible to identify the third party behind a misappropriation, including a provider shared between several retailers; you keep control of your subcontracting chain as a continuous signal, with no annual audit.
Sovereignty
DataBait is a company incorporated under French law, 100% owned by French shareholders and operated in France on sovereign infrastructure; none of your data transits through or is stored on our servers.
The infrastructure is hosted in France on a platform qualified SecNumCloud (ANSSI) and managed by a French company certified ISO 27001, beyond the reach of extraterritorial jurisdictions. And because DataBait accesses no payment data (card numbers, PAN) and limits itself to the contact channel of your fictitious accounts, deploying it adds no PCI-DSS scope to your information system.

Frequently asked questions
Every database holding customer data: customer file and CRM, customer accounts, order history, marketing and newsletter database, loyalty programme, and databases shared with your email and SMS routing providers, your ad networks, your marketplaces, your carriers, your agencies, and your SaaS or customer service providers. DataBait detects three families of signal:
The alert, sealed by a qualified eIDAS timestamp, proves your date of awareness, the certain starting point of your notification to the CNIL within 72 hours (article 33 of the GDPR) and, where the risk is high, of your communication to the customers concerned (article 34). If you run an online marketplace, Directive (EU) 2022/2555 (NIS2) classifies you among the important entities (annex II): its French transposition (the Résilience bill) will require a notification timeline to ANSSI (early warning within 24 hours, notification within 72 hours, final report within 1 month). DataBait tools detection, the timestamped incident dossier, and continuous monitoring of your providers.
Yes, if you segment your databases by recipient: DataBait injects dedicated fictitious accounts into each database you entrust, and a contact received on the accounts of a given database identifies the third party concerned. This is decisive when several retailers share the same provider, the vector of the 2024 serial leaks. On a single database shared with several recipients, a contact proves the misappropriation but does not identify who did it; attribution then requires your own investigation.
No. DataBait injects fictitious accounts into your customer file and your marketing databases, never into payment data (card numbers, PAN). It accesses no payment data, does not interfere with your payment service provider (PSP), and adds no PCI-DSS scope to your information system. Detection operates exclusively on the downstream contact channel (email, SMS, dark web); and it is precisely customer data, not payment data, that has become attackers' primary target.
None. DataBait runs as a fully managed SaaS, with zero infrastructure changes, zero operational overhead on the merchant's side, and no impact on your conversion rate. No agent to install, no schema migration, no connector to maintain. Deployment crosses no critical production environment: the fictitious accounts are injected through the same import routes as your new customers or your campaigns.
Data hosted in France, SecNumCloud-qualified hosting (ANSSI qualification), ISO 27001. Proof produced under French law (commissaire de justice, AFNOR NF Z67-147) and recognised throughout the European Union (qualified eIDAS timestamp). No transfer outside the EU. And because DataBait accesses no payment data, deploying it adds no PCI-DSS scope to your information system.
A database under DataBait that has never triggered an alert demonstrates, by construction, the absence of detectable misuse. For your executive team and your DPO, that is a measurable indicator of the maturity of your setup and of your providers'. It is also a trust argument you can put to your marketplace partners and your customers.
