Does all the customer premise require a probe or they can be centralized at HQ, which multi tenants can be created from there instead of subscribing to each probe(s) and service for each customer premise?

In the case for Datacenter Provider, Cloud Service Provider or Internet Service Provider(ISP), a single Sinefa probe (i.e. 1Gbps or 10gbps Probe) can be deployed at the edge router/Core Switch. And for each customer in the environment, we can configure individual segments (also known as internal source) in Sinefa App, so that each customer can gain access to view their own network environment.

Kindly note that in this scenario, aside from the 1gbps or 10gbps subscription, an internal source subscription fee will be charged for each customer segment created.
