TLS 1.0 End of Life

ALERT – InterFAX is Deprecating Support for TLS 1.0 | Deadline extended to June 30, 2018

In order to comply with all PCI-DSS 3.2 guidelines, InterFAX will stop supporting TLS 1.0 on June 30th, 2018.

Who does it concern:

Please make sure the web developer, network infrastructure, or IT Team in your company are notified, in order to implement the necessary actions to ensure continued fax service to all users in your company.

Requirement:

In order to comply with all PCI-DSS 3.2 guidelines, InterFAX will stop supporting TLS 1.0 (an older security protocol used on SSL secure web pages) on June 30th, 2018.

Potential Impact:

Unless your browser, email system or API supports TLS 1.1 or 1.2, your fax service will stop completely.

Action Recommended:

  • Review your system and check if you are choosing a specific security protocol when sending web requests to InterFAX.
  • If you are, we suggest that you change to TLS 1.2.
  • If you are not setting a specific security protocol, we recommend that you check with your infrastructure / Network team to ensure that your server is configured so that TLS 1.0 is disabled.
  • Test your application (see steps below).

*Please note, you will want to take the necessary steps to ensure that your entire system (unrelated to InterFAX) has also disabled TLS 1.0.

Testing your Application:

We have set test servers to work without TLS 1.0. We suggest you change the API endpoint for testing purposes only, as follows:

Non-PCI customers should change their API endpoint for testing to:

  • REST Customers: Change API endpoint to https://resttls.interfax.net
  • SOAP Customers: Change API endpoint to https://wstls.interfax.net

PCI customers should change their API endpoint for testing to:

Removal of TLS v.1.0 from InterFAX servers took place on June 01, 2018

  • REST Customers: Change API endpoint to https://resttls-sl.interfax.net
  • SOAP Customers: Change API endpoint to https://wstls-sl.fax.tc

More detailed instructions specific to applications for Browser Users, eMail (SMTP), and API Users:

APl Users

Some long-established users of our API may still be using TLS 1.0. Most developers will already be aware of the significance of TLS 1.0 and will have made the necessary changes. If you are in doubt, we strongly recommend you use our test environment to check the services works correctly. For details please contact InterFAX by return for instructions immediately.

Email (SMTP)

Email users are also most unlikely to experience any difficulties sending or receiving email. However, if your email server is more than 8 years old you may wish to check with your IT department to ensure TLS 1.1 or TLS 1.2 is enabled. In order to test your email service one can simply send a test fax to fax_number@notls.fax.tc). If the email is not delivered you will know that your email service needs to enable TLS 1.1 and TLS 1.2. If in doubt please email InterFAX by return for instructions on how to test your email service.

Browser Users

It is likely if you use a browser you will not be affected by the planned change. TLS 1.0 was replaced by TLS 1.1 in 2016 so the vast majority of devices will already be using TLS 1.1 or TLS 1.2 anyway and not be dependent on TLS 1.0. However, if you are in any doubt, instructions for checking and enabling TLS 1.1 and TLS 1.2 are provided for each browser below.
