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 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.

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.

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 main improvement needed is pricing because, as an enterprise solution, smaller partners do not often receive the attention they deserve.

Most of the time, in our experience at Danet Communications, we work with government offices, and they need the CDR. However, because CDR is affecting files such as MSI and EXE files, they are always creating new passes of scanning.
