Is it possible to transfer the replication data over public internet. Is there an construction possible that the cloud connector for an tenant can create an safe tunnel via public internet? Or is an dedicated VPN required.
It’s possible in theory, but not recommended in practice. Communication across networks can be encrypted using network encryption software such as VPN and IPsec. Zerto does not natively encrypt data across the WAN. Zerto recommends segregating management and replication traffic from the rest of the network, in order to mitigate any unknown vulnerabilities.
