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."
"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 prevents malicious or weaponized files from reaching users while reducing the risk associated with unknown, zero-day file-based threats."
"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."
"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 is flexible because, for a free product, you can enroll up to 50 devices, and I have only used about eight devices so far."
"MetaDefender OPSWAT provides that solution, and also the ICAP scans."
"I assess the effectiveness of MetaDefender in blocking or sanitizing content based on policy as very good."
"What I find most valuable about it is the design interface."
 

Cons

"Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand."
"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 could enhance the user interface and user experience, as the platform has many security capabilities, but some configuration and policy management tasks can take time to understand, especially for someone using the product for the first time."
"The documentation is not well written, and I often need to talk with support."
"The UI can be more user-friendly, and initial steps and policy tuning take some time."
"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."
"Reporting still requires improvement, but otherwise the solution is excellent."
"MetaDefender can be improved by upgrading the Linux version, which is using many free tools such as MongoDB, Postgres, and OpenSSL."
"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."
