For lawyers, notaires, and commissaires de justice
DataBait injects undetectable fictitious client accounts into your files (client file, case database, contact database, databases shared with your practice software vendors, your legaltech providers, and your hosts), each with a real email address and a mobile number, monitored 24/7. Since these accounts match no real client, 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
The legal professions hold, by their very nature, the most protected data there is: the mere list of your clients falls under professional secrecy, which is general, absolute, and a matter of public policy. And they are prime targets: ANSSI has devoted a report to the threat facing law firms, and the notarial profession records more than one cyberattack a week. A leak here is not a mere incident: it is an infringement of a fundamental right and exposure to disciplinary proceedings before your professional body.

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 practice software vendors, your legaltech providers, your electronic signature platforms, your hosts, or your digitisation and archiving providers, they are blind to what is done with it. The growing digitisation of the profession and of court procedures widens your exposure surface accordingly: every provider is a legitimate exit route for your data, 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 client, 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 a firm or a notarial office, this report covers both an internal and an external leak: it establishes that a client database left its perimeter, on what date, through which channel it was used, and with which forensic metadata. You hold proof already assembled to characterise the facts and decide on the steps to take, whether it concerns an associate bound by professional secrecy or a software vendor, legaltech, or host operating outside the scope of its DPA. Without the report, those steps remain theoretical.
Compliance
DataBait supports your GDPR compliance and your professional duty to preserve secrecy: 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 clients is high, to communicate it to them (article 34). The data you handle is among the most sensitive there is, including data on offences and convictions (article 10 of the GDPR) in litigation. Beyond the deadline, the leak itself is documented: in a CNIL inspection or professional disciplinary proceedings, you demonstrate what you knew, when, and what you did about it.
Professional secrecy imposes a duty of preservation that extends to your processors: practice software vendors, legaltech providers, signature platforms, hosts, and digitisation providers. The GDPR (article 28) requires you to select and monitor these third parties with due diligence. DataBait turns that diligence into continuous monitoring: injecting dedicated fictitious accounts into each database entrusted to a provider turns your oversight duty into a permanent signal, with no additional audit. And because it accesses none of your case documents, it brings no new third party into the circle of secrecy.
Use cases
DataBait detects and proves leaks and misuse of your customer data, whoever the actor.
A departing associate, clerk, or legal secretary walks off with the client file or the list of cases, to use it at a new firm or resell it. A fictitious account is contacted: you are alerted, and the report lets you bring disciplinary proceedings before your professional body and criminal action.
A practice management software vendor, a legaltech platform, a digitisation provider, or a host leaks or reuses your client data outside the DPA. Contact with a fictitious account reveals the misappropriation, backed by court-admissible proof, and identifies the third party if your databases are segmented.
Ransomware hits your firm, a scenario ANSSI documents as recurrent: several French firms compromised, and even ministry documents stolen through a law firm. Your fictitious accounts surface on the dark web: you learn it from monitoring, not from your clients' complaints. You warn them of the phishing, identity-theft, and blackmail risk, then notify the CNIL and your professional body — before the press picks it up.
How it works
DataBait turns every attempt to misuse your customer data into proof.
DataBait injects undetectable fictitious client accounts into your files (client file, list of cases and matters, contact database, databases shared with your practice software vendors, your legaltech providers, your hosts, and your digitisation or archiving 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. DataBait accesses none of your real case files.
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, your professional body, 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 security lead 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, your professional disciplinary proceedings, and your claims.
Integration
DataBait is a fully managed SaaS: it runs with no agent and no change to your infrastructure, 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 clients.
Protecting the firm
DataBait injects the fictitious accounts into your client file, your case database, and your practice management software. You tool your own compliance (GDPR, professional secrecy) without changing your information system, and without DataBait accessing any of your case documents.
Third-party oversight
DataBait injects fictitious accounts dedicated to each database you share with your practice software vendors, your legaltech providers, your signature platforms, your hosts, and your digitisation or archiving providers. Segmented by recipient, these databases make it possible to identify the third party behind a misappropriation; you turn your processor-monitoring diligence (GDPR art. 28) into 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 case file and no document covered by professional secrecy, and limits itself to the contact channel of fictitious accounts, it brings no third party into the circle of secrecy and in no way weakens your duty of confidentiality.

Frequently asked questions
Every database holding client data: client file, list of cases and matters, contact and correspondent database, diary, and databases shared with your practice software vendors (practice management, accounting), your legaltech providers, your electronic signature platforms, your hosts, and your digitisation or archiving providers. DataBait detects three families of signal:
No. DataBait accesses no case file, no document, and no correspondence of your real clients. It injects fictitious client accounts, generated from public statistical datasets, and monitors only their contact channel (email, SMS). Your real data never leaves your information system, and DataBait brings no third party into the circle of professional secrecy. A lawyer's professional secrecy (article 66-5 of Law No 71-1130 of 31 December 1971) is general, absolute, and a matter of public policy; notaires and commissaires de justice are bound by it as public and ministerial officers. DataBait was designed to preserve it by construction.
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 clients concerned (article 34). The data you handle is particularly sensitive, including data on offences and convictions (article 10 of the GDPR) in litigation. Beyond the deadline, the leak is documented: in a CNIL inspection or professional disciplinary proceedings, you demonstrate what you knew, when, and what you did about it. DataBait also gives substance to your diligence in monitoring your processors (article 28 of the GDPR).
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. On a single database shared with several providers, a contact proves the misappropriation but does not identify who did it; attribution then requires your own investigation.
None. DataBait runs as a fully managed SaaS, with zero infrastructure changes and zero operational overhead on the firm's or office's side. 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 clients.
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 case file and no document covered by professional secrecy, deploying it in no way weakens your duty of confidentiality.
A database under DataBait that has never triggered an alert demonstrates, by construction, the absence of detectable misuse. For you and your DPO, that is a measurable indicator of the maturity of your setup and of your providers'. It is also an exhibit you can produce in support of your diligence, not least before your professional body.
