Security Enhancement - Ireland Bank

Security Enhancement Coming May 1, 2018. Are You Ready?

The security of your data is our number one priority! For this reason, Ireland Bank is making a change to our security protocol. We will be officially retiring TLS 1.0 security protocol support on our online banking services in order to align with industry best practices and ensure that your data continues to be highly secure.  This change is set to take place on May 17, 2018.

What does this mean for you? You will need to have the most recent version of your browser downloaded on your computer and ensure your mobile device’s operating system is up to date.


Please reference the chart below for browser versions that support TLS 1.1. and higher. If you are using a browser version that is lower than those listed below, you may not be able to access some or all of your online banking services. Click on your preferred browser for instructions on how to verify your browser version and how to update it if needed.

You can test your TLS “score” by visiting this website and check if your browser has already disabled TLS 1.0 by visiting this website.

Microsoft Internet Explorer (IE): version 11 and higher
Microsoft Edge – all versions are up to date
Google Chrome version 38 and higher
Mozilla Firefox: version 27 and higher
Apple Safari
          Desktop Safari: versions 7 and higher for OS X 10.9 (Mavericks)
          Mobile Safari: versions 5 and higher for iOS 5



Users operating on Android version 4.4 and lower may be impacted by the disablement of TLS 1.0 as these versions do not support TLS 1.1 and 1.2. Upgrading to 5.0 or higher will fix this issue.


Frequently Asked Questions

Q: What is TLS?

A: TLS stands for “Transport Layer Security.” It is a security protocol that provides privacy and data integrity between two communicating applications. It’s the most widely deployed security protocol used today, and is used for web browsers and other applications that require data to be securely exchanged over a network.


Q: What is the change, when is it happening and how will I be impacted?

A: Ireland Bank is requiring an upgrade to TLS 1.1 or higher beginning on May 17, 2018. On that date, we will begin disabling the TLS 1.0 encryption protocol, which may prevent you from accessing some or all of your online banking services. You may have to upgrade your browsers and/or mobile operating systems.


Q: Why is Ireland Bank doing this?

A: TLS aims to provide privacy and data integrity between two communicating applications. TLS 1.1 and above provide significantly higher security controls than TLS 1.0. Protecting your data is of the utmost importance for us, and this disablement will allow us to better ensure the security of your data. Our goal is to make this process as seamless as possible while maintaining the highest security standards.


Q: What happens if I don’t upgrade their browsers or mobile systems in time?

A: On the May 17, 2018 cut-off date, all systems will be changed so TLS 1.0 traffic will be directed to a page that will say “Stronger Security is Required.” Please update your browser and/or operating system as indicated above.
