Aaron Alornyenu - PeerSpot reviewer
Helps us stay compliant, has excellent malware detection, and is stable
The solution helped our organization stay 100 percent compliant with industry standards. MetaDefender Email Security can be set to be very aggressive for identifying attacks. This can be done based on how we want it. If we set it to this level, most of our emails will be blocked because the system will block anything that looks suspicious. We will also need to set the spam severity. This is the severity of everything, including phishing, spoofing, and other types of attacks. I would give the solution's ability to identify attacks a nine out of ten. MetaDefender helps us improve our spam catch rate. Any spam we receive is usually due to user subscriptions. We can specify rules of exclusion to meet our requirements as well. It also detects and blocks the links with suspicious codes. MetaDefender Email Security's multi-scanning capabilities for malware detection work based on how we set the parameters. The solution perfectly detects malware. MetaDefender can identify and disarm emails in zero-day attacks.
