File sanitization has protected critical networks and prevents hidden malware from entering
In my experience, the best features MetaDefender offers include the number of different antivirus engines that can scan files through multi-file scanning, often using 20 to 30 engines, with the top premium package around 33 engines, capturing 80 to 90% of malware in all those files. If any engine detects malware, the file is blocked, which increases detection because different engines catch different malware. When dealing with central government and defense, we find that if there is any kind of malware on the network or the file, whether that is a software file, hard disk file, or a pen drive, it cannot be allowed on the network. This is when we put it into the sandbox and perform file sanitization to ensure that nothing malicious comes into the network. Whenever we are dealing with central government or defense contracts, MetaDefender's core philosophy of trusting no file means it scans files, rebuilds them, and verifies their reputation, ensuring they contain no malicious content. This positively impacts our organization by detecting malware and stopping any kind of data leaks through the network. In terms of measurable outcomes across central government and defense, we are seeing saved time when files go through the antivirus file scanners. In financial services, such as with mortgage applications, the process sends files straight into MetaDefender file scanning that cleans out any malicious content.

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.

Pros

"OPSWAT is the best alternative."
"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."

Cons

"The main improvement needed is pricing because, as an enterprise solution, smaller partners do not often receive the attention they deserve."
"The UI can be more user-friendly, and initial steps and policy tuning take some time."
"What I would like to see improved in MetaDefender includes reducing the high cost of the license, as the pricing is very high."
"Some capabilities are lacking in reporting because we do not have full statistics that are easy for users to understand."
"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."
"The main improvement needed is pricing because, as an enterprise solution, smaller partners do not often receive the attention they deserve."
"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."
