Featured Reviews

Nasseer Qureshi - PeerSpot reviewer
Email security effectively detects a wide range of threats and improves productivity
Since we have been using Check Point Harmony Email & Collaboration for a year, we haven't encountered significant challenges. However, it would be beneficial if it could support other email security services beyond Microsoft and Google. Integration with other platforms would enhance its appeal since the features are commendable. While the analytics are commendable, they don't provide deep dive insights. They show the overall counts of malware, phishing, and business compromise emails, but there isn't a robust ability to dive deeper into those categories to see specifics. Analytics should allow us to explore which users received malware emails the most or trends among departments. Currently, we have to sift through manually, which is not ideal. A more profound analytical capability would elevate the tool to become the complete email security solution for any user.
ShaheenKapery - PeerSpot reviewer
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.
