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.

An easily integratable solution that helps scan files
I recommend leveraging the data and using case transcripts to understand how the tool can address your needs. Additionally, testing the solution in your environment can be helpful. If we keep it updated and ensure that the engines and the latest definitions are up-to-date, the solution functions without problems. It continues scanning without any delays. I rate the product an 8 out of 10. With OPSWAT Filescan Sandbox, we can scan various file types, including IOCs, Python compressors, and QR codes from images. All the configuration settings are user-dependent and can be modified over time. It's highly configurable—you can easily navigate to the console, click on any option, and quickly adjust settings, including the default size.

Quotes from Members

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

Pros

"I like the simplicity, the way it works out of the box. It's pretty easy to run and configure. The integration of the network devices with the ICAP server was easily done."
"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."
"The effectiveness of the solution in blocking or sanitizing any content based on our policies is excellent."
"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."
"OPSWAT is the best alternative."
"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 has positively impacted my organization by reducing the risk of file-based attacks, which has significantly improved our overall defense against phishing and malware delivery techniques."
"The best feature of MetaDefender is that it can isolate USB devices from the connected network, blocks malware and unsafe files, and ensures all endpoints follow security policy, so that my organization remains safe and reduces the risk of these threats."
"What I find most valuable about it is the design interface."
 

Cons

"While MetaDefender's mail gateway already gives fewer false positives, there is still room for improvement in reducing those even further."
"From the last year that we integrated OPSWAT in our company, I have not seen any improvements."
"The main improvement needed is pricing because, as an enterprise solution, smaller partners do not often receive the attention they deserve."
"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."
"The user interface is complex initially, scanning large or complex files can take longer than expected, false positives occasionally require manual review, and the pricing is somewhat high."
"Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand."
"I would like to see improvements in the tool's automation capabilities."
"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."
"There's a size limitation, allowing us to scan only small files."
 

Pricing and Cost Advice

"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."
"The tool is free, but there's a size limitation, allowing us to scan only small files."
