Effective threat protection with room for cost and usability improvements
There are some drawbacks that I would mention. To be frank, enterprises always look for cost benefits, so Kaspersky could implement some price benefits. Additionally, regarding know-how, if I am an experienced person it's fine, but when someone novice is working with it, they need information about why certain actions are required. Security is a field that is very vast, and implications are not known to everyone. In future updates, a quick walk-through and know-how features would be beneficial, such as information text at relevant places. This will increase usability. Feature-wise, an impact analysis would be a really good addition.

Helpful support, and useful dashboards
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.

"The DLP should be upgraded and has room for improvement."
"Although the number of AV engines is good, it could be better."
 

Pricing and Cost Advice

"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
