Are you talking about this part of the 2.5 release notes?
- Packet Copy Support - In addition to redirecting traffic through a service, NSX-T now supports the Network Monitoring use case, in which a copy of packets is forwarded to a partner Service Virtual Machine (SVM), allowing inspection, monitoring or collection of statistics while the original packet does not pass through the network monitoring service.
If it is, what this means is that NSX-T is now capable of integrating with partner SVMs leveraging packet copying. While NSX-T has this ability, partners have to go through testing and validation of their solutions. When this happens it will be posted here: VMware Compatibility Guide - Networking and Security Services for NSX-T
The compatibility guide is where you should look and where approved integrations are published. Now with this new possibility using packet copy new integrations should developed and when they are ready they will be published in the compatibility guide.
