Notice: Salesforce TLS1.0 Disablement Announcement

[Retired Member]

Dear valued Palo Alto Networks customer,

Starting on March 10, 2018, Salesforce will disable the TLS 1.0 encryption protocol (Click here for information on TLS). The disablement of TLS 1.0 will prevent it from being used to access the Salesforce service within inbound and outbound connections.

Impact

You will experience issues accessing Case Management if you’re using a non-supported browser or if you have disabled the supported encryption protocols in your browser. 

How to test your browser compatibility

If you are able to view this test site–which has TLS 1.0 disabled–without errors, access to Salesforce via your browser should not be impacted by this change, and no action is required.

Action required for browser compatibility

If you experience errors viewing the above test site, you will need to ensure your browsers are compatible with TLS 1.1 or higher by March 10, 2018. Please note: If your browser is not compatible with TLS 1.1 or higher after we make this change, you will not be able to access Case Management. We recommend that you begin planning to upgrade your browser version in order to support TLS 1.1 and TLS 1.2 by March 10, 2018.

To update your browser, please refer to the following link: https://browser-update.org/update.html?force_outdated=true

NOTE: The minimum required action is to enable TLS 1.1 or TLS 1.2 encryption protocol within your browser security settings. Although we recommend disabling TLS 1.0 for a more secure browsing experience, it is not required. For example, if a user has protocols TLS 1.1 or TLS 1.2 enabled within their browser's security settings, they will be able to successfully connect to Salesforce after it disables TLS 1.0 on March 10, 2018.

Please refer to the compatibility guidelines below:
