What SNEXI has confirmed
SNEXI says snexi.fr suffered a cyberattack on Wednesday, 2 September 2026, resulting in a personal-data breach. In its notice, the company says it secured its systems, notified the French data protection authority CNIL and began investigating which data and people may be affected. That investigation is still ongoing.
SNEXI has not published a number of affected people or a technical explanation for the attack. Details reported by third parties should therefore not be presented as the company's final assessment.
What data may be affected?
According to SNEXI, depending on the person’s profile, potentially compromised data may include first and last names, email addresses, postal addresses and phone numbers. The company says the affected environment contains no financial, banking or sensitive data.
This list comes from SNEXI’s incident notice. Its privacy charter describes information the service may process during normal operations; that general list does not establish which data were exposed in this attack.
Why these details call for extra care
SNEXI provides property inspection and diagnostic services. A message mentioning an agency, an address or an appointment could therefore look credible to a landlord or tenant, even though those details do not prove who sent it.
This is a risk to watch for, not evidence that fraudulent messages have already used the data. Verify any unexpected request for payment, documents or access codes with the agency using a number you already know.
How to check whether you are affected
SNEXI directs people who want to check their situation to donnees-personnelles@snexi.fr. The company asks for information needed to identify a record and says it will share investigation updates and any additional measures.
Do not send an identity document, password or login code in reply to an unexpected message. Open SNEXI’s official website yourself to find the notice and its contact details.
What agencies and property managers should review
Agencies, property managers and diagnosticians that use SNEXI should check which records and contact details they provided, then ask the provider whether their files fall within the scope still under investigation. Flash-Immo also highlights reviewing processor agreements, notification channels and the amount of data shared.
SNEXI has not yet published the number of people affected or the technical cause of the attack. Organizations should not repeat third-party figures or scenarios as though the company had confirmed them.
The link with Soclyde
Soclyde does not protect SNEXI or undo the exposure of contact details. A local-first encrypted vault can help a team organize unique passwords for its tools, but checking records, notifications and changes to SNEXI accounts must be handled with the relevant services.
