Use a network-based filter
Elisa Email Security stops spam and other malicious email traffic while it is still in Elisa’s backbone network. This way, malicious traffic will not overload your network or internet capacity.
All of the network components related to the service environment are fully duplicated, and they are located in Elisa’s backbone network in a decentralised manner.
Email traffic is directed from the environment to the service and back with email routing that is completely cloud-based.
