What is changing?
After June 15, 2018, PPM Pro will no longer accept TLS 1.0 connections to its application and login servers. TLS 1.1 and 1.2 will continue to be supported.
Why are we making this change?
TLS 1.0 has been around since 1999. The IETF and several researchers have discovered vulnerabilities in TLS 1.0. Our security partners and several of our customers have requested that we join many leading Internet companies in no longer supporting TLS 1.0.
What will be the impact of this change?
There are 2 areas of potential impact: browsers and custom integrations
Modern browsers, including all of our supported browsers, support TLS 1.2 which has long been our recommendation for HTTPS connections. We have examined our connection logs andhave detected no TLS 1.0 connections to application or login servers in the past 30 days so we believe this change will have little to no impact to browsers., other than improving the security of our systems and our customers' data.
If you're using a Planview-managed integration, it is already using TLS 1.2. As of today, about 5% of the traffic to api.innotas.com is using TLS 1.0. If you have a custom integration, you will need to upgrade it to TLS 1.1 or 1.2 no later than June 15, 2018.
How do I know if I'll be impacted?
