Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.
