It is essential to adopt an attitude in line with the practices of the Internet and to protect your computer or smartphone.

Adopt suitable attitudes to browse the Internet safely and securely

Do not disclose your identifiers and passwords

  • Do not tell anyone your identifiers, passwords, digits on your personal key card, PIN codes or bank data.
  • Your RIB/IBAN enables your bank details to be disclosed both for payments and standing orders. Limit its distribution only to people or organisations you trust.
  • Be careful also of people looking at what you are doing: when you enter a password or your identifiers, particularly on a smartphone, make sure no-one is looking over your shoulder.
  • When you enter your password on the becm.fr site, your browser sometimes offers to save it. For security reasons, always refuse to have your password saved.
  • Change your password regularly and choose a different one for each site. Avoid passwords which are too simple and obvious.

Be wary of unsolicited e-mails or SMSs

  • Be careful who you give your e-mail address and telephone number to. Only give them to individuals or organisations you trust.
  • Do not open e-mails and SMSs from an unknown source. The same goes for any attachments. They may contain malicious software.
  • Never enter your identifiers or passwords after clicking on a link in an e-mail whose origin you are not sure of. This type of request is frequently used by scammers to try to steal from you.

What do I do if I receive a phishing e-mail?

  1. Do not click on any links in the e-mail or on any attachments.
  2. Transfer the suspect e-mail to our department dealing with fraudulent e-mails: phishing@cic.fr.
  3. Lastly, delete it.

You think you have responded to a phishing e-mail

  1. Change the password you use to access your accounts straight away.
  2. Contact your advisor as soon as possible.

For any attempt at fraud not directly involving {{perso.dico.banque-le}}

You can notify the competent organisations (in french):

Your identifier and password are secret. Do not divulge them to anyone!

Logging on and off on banquetransatlantique.com

When you connect to your Customer Space with your identifiers, you open a temporary logon session. If you forget to logoff, the session will close automatically after 10 minutes of inactivity.

The date and time of your last logon appear on the homepage of your Customer Space.

Our secure site guarantees a secure connection and encryption of your confidential data. You can check this security by the presence of « https: » before the address and the padlock icon. Double clicking the icon displays data relating to the security certificate for the site.

Make your devices secure for the Internet

Protect your device

Install the latest updates for your software. They generally incorporate the latest security patches

For greater security, equip your device with:

  • antivirus software regularly and automatically updated to protect it against virus, worm or Trojan horse infections which are very widespread throughout the Internet.
    Here is a non-exhaustive list of the most standard antivirus software: Avast, BitDefender, Kaspersky, Sophos, Panda, Norton Symantec, McAfee.
  • a firewall. This software prevents unauthorised access to your computer and the data it contains.

Adopt good habits on your smartphone and tablet

Protect the confidential data contained on your smartphone.

  • Install an anti-theft application. These applications allow you to locate your smartphone, lock it or erase all the data remotely if it is stolen.
  • Always download your applications from reliable sources.
