TLS v1.2 Upgrade and Client Component Update for Zoho CRM

TLS v1.2 Upgrade and Client Component Update for Zoho CRM

Hello folks,

Please note that, we will be deprecating support for browsers, APIs, and Plugins with older protocols from today (13th May 2019).

Please be informed that we will be retiring support for browsers, APIs, and Plugins with older protocols by October 31, 2018. After this date, you will be required to use browsers, APIs and Plugins that support TLS v1.2 and the latest client component updates we've made in Zoho CRM. 

We have made some changes in our client components for better performance and user experience in Zoho CRM. In order for these changes to be supported and to meet the updated PCI standards, you will be required to update your processing solutions to TLS v1.2.
How can you adapt to this change?
We recommend that you use any of the following browsers, that will support this latest update:
  • Google Chrome, version 49 and above
  • Mozilla Firefox, version 44 and above
  • Safari, version 9 and above
  • Internet Explorer, version 11 and above
  • Opera, version 45 and above
The following versions of the mobile platforms support the latest update:
  • Google Android, version 4.1 and above
  • iOS, version 5.1 and above
  • Windows phone, version 8.1 and above
Kindly update your Office and Outlook plugins to the latest versions from the respective links:
If you are using any of the following programming languages, you will have to upgrade it in order to communicate with our API: 
  • Java 6u45
  • Java 7u25
  • OpenSSL 0.9.8y
  • .NET 4.5 and below
  • .NET 4.5 (settings should be changed to enable TLS 1.2)
PhoneBridge: If you are a PhoneBridge adapter user, please make sure you are using the latest java version (Java 8) in the machine/server where you have installed our PhoneBridge adapter.

SalesInbox: Please ensure that you update to the above mentioned browsers that will support the latest update. 

What is TLS?
Transport Layer Security (TLS) is a cryptographic technology protocol used to provide secure transfer of sensitive information over the internet.

Why is this update necessary?
According to PCI standards, TLS v1.2 is the most advanced protocol yet as it eliminates the vulnerabilities faced by the previous versions, i.e, TLS v1.0 and v1.1. All users who use secure servers and browsers to access the data and API from Zoho are expected to make this update. If you are using a Webhook to link Zoho to an external site, your browsers are required to support HTTPS and TLS v1.2. 
 
We have also made some major enhancements in client components that will not be supported in old browser versions.

You can refer to this link for further details regarding the requirements. You can also use this link to test if your browser supports TLS v1.2.

Additionally, for API users, we will add a warning node when the connection is made from unsafe systems. We will keep you posted in this space for further updates.
