Transport Layer Security (TLS) 1.1 Deprecation in Anaplan API Services

Valued Contributor

In accordance with industry-tested best practices, Anaplan will be deprecating support for Transport Layer Security (TLS) 1.1 in October 2020. This necessary move to increase your data security will impact some API integration customers. Those customers impacted will need to upgrade to TLS 1.2 by October 2020.

The below article outlines the situation and the impact. We have also prepared an FAQ to help you understand whether you’re impacted and the actions you need to take. We will add more information to this article as it becomes available.

What Is Happening?

Anaplan is disabling TLS 1.1 for data integrations with Anaplan in October 2020. Starting October 2020, only TLS 1.2 and above are supported. The benefits of upgrading to TLS 1.2 have been discussed in detail in the NIST Special Publication 800-52 “Guidelines for the Selection, Configuration, and Use of Transport Layer Security (TLS) Implementatio...”.

What Is the Impact?

Starting October 2020, Anaplan will only support TLS 1.2. Any data integration connector or client using TLS 1.1 no longer communicate with the Anaplan platform, meaning that those integrations will fail.

Why Is this Happening?

TLS is a security protocol that provides privacy and security to applications that communicate with each other over a network. This ensures that connections are made with the intended endpoints by using encryption and identity verification. Major browsers are deprecating support for TLS 1.1 in 2020. Following industry best practices for connection and data security, Anaplan is deprecating support for TLS 1.1 and making TLS 1.2 mandatory for data integrations from October 2020.

Who Is Impacted?

Customers using data integration solutions which connect to Anaplan Application Programming Interface (API) services using TLS 1.1. are impacted. If a data integration connector or client only supports TLS 1.1 and does not support TLS 1.2, such connector or client will not be able to connect to Anaplan starting October 2020.

Check which integrations require an upgrade here

You are NOT impacted by this change if you are only using the following:

Informatica Anaplan Connector

SnapLogic Anaplan Snap Pack

Tableau Connector for Anaplan

Anaplan Connect 1.4.x

MuleSoft v3 Connector for Anaplan (supported on Mule runtime 4.x)

I am using other integrations, What Do I Need to Do?

To prepare for this change and ensure that your organization is not impacted, carry out these steps BEFORE October 2020. We recommend that you provision enough time to test your connections:

  • Upgrade your Anaplan Connect Java version to Java 8.161 or above if your organization uses Java 6.x or 7.x or Java versions less than 8.161. See how in this FAQ.

  • Upgrade your non-Java based integrations solutions to a version that uses TLS 1.2 by default.
