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.

Has improved our vulnerability tracking and supports cloud-based monitoring with scheduled scans
We don't have any issues with Tenable One Exposure Management Platform. It works well for us, but the only problem is the licensing aspect. In the license, it becomes problematic because when we go to cloud security for vulnerability management, it will take five licenses instead of the one-on-one license that vulnerability exposure management requires. The license needs to be reviewed.
