At GMCU, we have systems in place to help keep your accounts safe.


Our system is known as VIGIL – a 24/7 call centre with artificial intelligence that monitors transactions to detect fraud. VIGIL has now introduced a 2-way SMS feature; a new way to protect you by verifying transactions with you directly in real-time.

If a transaction on your account is flagged as suspicious, you will be sent an SMS message asking you to confirm or deny that the transaction is legitimate. You can then simply respond to the text with a “yes” or “no”. This helps the system learn to identify potential fraud, and can ensure restrictions are put in place in response to illegitimate charge attempts. Once you respond, you will receive further instructions on what to do next.

In 2023, this system was upgraded to include Fully Integrated 2-Way SMS. This has a range of benefits, including:

  • An addition to existing VIGIL security systems to increase your protection
  • Smart and adaptable rules to accommodate for trends or new threats
  • Automated processes, removing the risk of human error or relying on a fraud officer being available
  • A better user-experience with improved response speed and minimised impact to cardholders.

This is an important reason for you to make sure that your contact details are always kept up-to-date. If your address or phone number has changed, you can update them using the GMCU Mobile App, Internet Banking, or by contacting your local branch.
