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.

They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward. I haven't tried it in a while since then. Since I can't turn it off on a per-user basis, I had to turn it off globally. I have certain exceptions for not doing the sanitization, and how to set those up is not intuitive. It would be useful if there were a better way of doing that. Using digital certificates is hard. It would be better if it used Windows Servers' built-in certificate management.

MetaDefender Email Security's multi-scanning capabilities for detecting malware are satisfactory. While the package offers eight, twelve, and sixteen scans, the premium solutions that include advanced anti-agents such as Trend Micro, McAfee, and CrowdStrike are costly. The basic mode of the package we sell only offers basic scanning and most people are likely unaware of the antivirus engine's name. While multi-scanning is a useful feature, we would prefer to see the basic version include more advanced scanning options. The DLP should be upgraded and has room for improvement. The central management center is not yet at the level of an enterprise. It has all the necessary components to create a standalone solution, and the local management center has everything required. However, when it comes to selling to larger enterprises, the central management center is still at a junior level. This means that there are many features, such as reporting based on login and connectivity to external systems, that require manual configuration rather than being included in a complete solution from a management perspective. The solution has many components, but it lacks a cohesive central focus for customers. It is, for example, a company that is an OT security company, but it suddenly shifted its focus to cloud security for secure access, which is confusing. The price of MetaDefender Email Security has room for improvement. The configuration has room for improvement.
