We hope you are enjoying your journey with Zoho Projects. Over the last few months we have rolled out several new features and have enhanced our security protocols. To ensure that your data is transmitted securely and to conform to the latest PCI standards we will be moving to TLS v1.2 from November 1st 2018. The older TLS 1.0 and 1.1 will no longer be supported.
Users who use secure servers and browsers to access data and APIs from Zoho Projects will have to upgrade to TLS v1.2 to continue doing so.
