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

"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."
"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 percentage of accuracy is great and the integration of multi-scanning and Content Disarm and Reconstruction affects my data security operations effectively because OPSWAT blocks the file types that we are not willing to have inside the company or are not approved."
"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."
"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."
"OPSWAT is the best alternative."
"The effectiveness of the solution in blocking or sanitizing any content based on our policies is excellent."
"What I find most valuable about it is the design interface."
 

Cons

"What I would like to see improved in MetaDefender includes reducing the high cost of the license, as the pricing is very high."
"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."
"Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand."
"The UI can be more user-friendly, and initial steps and policy tuning take some time."
"From the last year that we integrated OPSWAT in our company, I have not seen any improvements."
"While MetaDefender's mail gateway already gives fewer false positives, there is still room for improvement in reducing those even further."
"The documentation is not well written, and I often need to talk with support."
"I did not manage to enroll my IoT devices, including my child's device running on iOS and some Amazon products."
"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."
