Managing TLS Protocol
Configuration with the TLS
Configurator Utility 12
Starting with vSphere 6.7, only TLS 1.2 is enabled by default. TLS 1.0 and TLS 1.1 are disabled by
default. Whether you do a fresh install, upgrade, or migration, vSphere 6.7 disables TLS 1.0 and TLS 1.1.
You can use the TLS Configurator utility to enable older versions of the protocol temporarily on vSphere
6.7 systems. You can then disable the older less secure versions after all connections use TLS 1.2.
Note Starting with vSphere 6.7, the TLS Configurator utility is included in the product. You no longer
download it separately.
Before you perform a reconfiguration, consider your environment. Depending on your environmental
requirements and software versions, you might need to re-enable TLS 1.0 and TLS 1.1, in addition to TLS
1.2, to maintain interoperability. For VMware products, consult VMware Knowledge Base article 2145796
for a list of VMware products that support TLS 1.2. For third-party integration, consult your vendor's
documentation.

Ports That Support Disabling TLS Versions
When you run the TLS Configurator utility in the vSphere environment, you can disable TLS across ports
that use TLS on vCenter Server, Platform Services Controller, and ESXi hosts. You can disable TLS 1.0
or both TLS 1.0 and TLS 1.1.
The following table lists the ports. If a port is not included, the utility does not affect it.
