Bankinter was the first bank to incorporate technology to make life easier for its customers. We also strive to offer you a high level of protection and privacy for your data and operations. Accordingly:

  • High security standards are implemented and developed to protect the authenticity, confidentiality, integrity and availability of Information Systems from an operational and technical standpoint.
  • Online Banking web servers use an Extended Validation Certificate issued by Entrust.
  • All information transmitted is encrypted with standard algorithms and keys established on each connection using TLS protocol, and our systems connected to the Internet have been protected by “firewalls” and intrusion detection systems, which would prevent a possible attack by protecting our Online Banking.
  • We run regular internal and external Intrusion Tests on our Information Systems.

Bankinter is the first Spanish financial institution to simultaneously receive the ISO 22301:2012 and ISO/ISEC 27001:2013 certificates from the British Standards Institution (BSI). These certifications guarantee the bank's operability and compliance with its requirements regarding the Business Continuity Management System and the Information Security Management System.

Additional security measures

  • Every time you sign an transaction, you enter your coordinates using a display panel (this system averts the risk of malware that try to capture information using keystrokes [“KeyLogger”]).
  • You are automatically logged off after 20 minutes of non-use (30 minutes in the Broker). This measure prevents someone else from accessing your data on your computer if you forget to log off (by not clicking on Log Off).
  • We have control systems for custom operating limits, so that a customer cannot carry out operations above a certain amount; and general operating limits, which limit the total amount of transactions that can be carried out through our websites. This measure limits the risk of any loss.
  • Safer transfers thanks to the two-factor authentication factor that Bankinter uses if you provide us with your mobile phone number.
  • We show you the date and time of your last connection and the last password change so you can detect if anyone has connected on your behalf in the past few days.
  • We ask you to change the password the first time you log in so only you know it. That way, we know it's really you.
  • Your online banking username and password must be at least 6 characters long, so they are difficult to guess.
  • You can choose not to receive statements of account or regular mail about your banking activity; this also means there is less risk of someone finding out about your financial situation by looking through your mailbox. All statements of account and supporting documents for transactions are available and can be consulted on the website.
