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.

File protection has improved and now keeps millions of daily transfers secure and compliant
In my organization, while using this tool, we found that there were a few files flagged as suspicious; however, those were not suspicious and it was a false positive, so that can be improved. False positive results were an issue, and it took time to scan files if the file size was greater than 1 GB. For larger files greater than 1 GB, it needs to be improved. In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective; however, in other types of files, it was very effective and could scan files properly. We have already covered all the main suggestions; however, it can be improved to reduce false positive results, and scanning could be faster to process more files in a day.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"I would recommend it to others as it's easy to use."
"The most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."
"The password thing is very good, and the overall URL protection."
"The most valuable features of this solution are its ease of use and operation efficiency."
"The most valuable aspect for me is the user-friendly interface."
"The most valuable features of the solution are the antivirus and child protection features."
"Kaspersky Security for Internet Gateway has positively impacted our organization by helping us control unwanted attacks and limiting our exposure to risks."
"MetaDefender is 100% stable, making it one of the best cybersecurity solutions we offer, which provides confidence in promoting and recommending it to others."
"MetaDefender is flexible because, for a free product, you can enroll up to 50 devices, and I have only used about eight devices so far."
"I assess the effectiveness of MetaDefender in blocking or sanitizing content based on policy as very good."
"The best features of MetaDefender include its ability to detect malware and vulnerabilities, which I also use at server levels, including production and testing servers, helping me identify and address vulnerabilities by applying patch updates."
"MetaDefender is a useful tool for scanning all incoming and outgoing files and keeping our applications and servers in compliance, and I found it useful because we can integrate it with multiple file transfer tools such as Globalscape EFT, GoAnywhere, or Sterling, which is the best feature as it integrates with multiple tools."
"For one of my clients, a major bank in Turkey, they reported saving approximately 30 percent of their SOC time on analyzing emails since implementing MetaDefender."
"My advice to others looking into using MetaDefender is that if you are looking ahead at a solution which can be implemented quickly and at a lesser cost, go ahead with it."
"OPSWAT is the best alternative."
 

Cons

"The customer support of the product is an area with shortcomings where improvements are required."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"When I do a configuration, I do not know what implication it will have downstream."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"I believe the absence of a procedure is the main issue."
"There is room for improvement in terms of the pricing."
"The UI can be more user-friendly, and initial steps and policy tuning take some time."
"I did not manage to enroll my IoT devices, including my child's device running on iOS and some Amazon products."
"In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective."
"The main improvement needed is pricing because, as an enterprise solution, smaller partners do not often receive the attention they deserve."
"While MetaDefender's mail gateway already gives fewer false positives, there is still room for improvement in reducing those even further."
"In some cases, the reconstruction of the file led to a failure of code deployment and it flagged a valid file as malicious, which was not effective; however, in other types of files, it was very effective and could scan files properly."
"I would rate it an eight because its interface can be improved and it can improve their integrations as well, so there is room for improvement."
"From the last year that we integrated OPSWAT in our company, I have not seen any improvements."
 

Pricing and Cost Advice

"Personal computer licenses can be expensive if you were to scale the solution extensively. However, large companies will most likely use Endpoint solutions and not this one."
"I rate the product's price an eight on a scale of one to ten, where one is very cheap, and ten is very expensive."
"It is expensive."
"I would rate the pricing a seven out of ten, with ten being very expensive and one being cheap. It's neither too cheap nor too expensive."
"I am okay with the pricing."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"We bought a three-year license, and that was pretty expensive. We agreed that it was really worth buying. It could be cheaper, but we understand that quality comes at a price."
