Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

Helps us reduce phishing email attacks and has a user-friendly dashboard
It is the best product. It helps reduce spam and phishing attacks. It has user-friendly Real-Time Phishing Mitigation features for environmental protection. It primarily focuses on verifying security features like SPS (Sender Policy Framework) and Smart DKIM (DomainKeys Identified Mail). The DLP feature ensures that only emails meeting the required security standards pass through the secure gateway. The configuration and management of the policies and settings are easy to navigate. I rate it an eight out of ten.
