MetaDefender support is highly praised for quick and professional responses, resolving issues efficiently with expert technical assistance.
Sentiment score

NetWitness NDR's customer service is generally efficient and highly regarded, though some users report occasional slow response times.
This can save time because many vendors, when they check something and ask for logs, need those logs from the beginning.

When it comes to my communication with agents, I find they are responsive and professional.
Integration Technician at danet
Their customer service team, distribution team, and regional sales managers provide excellent aftercare and set us up for upselling across the entire MetaDefender portfolio.

Partner Account Manager at a wholesaler/distributor with 51-200 employees

Room For Improvement

MetaDefender users want improved speed, usability, affordability, notifications, reporting, documentation, installation, automation, and threat intelligence integration.
NetWitness NDR requires improvements in UI, scalability, detectability, integration, session times, pricing, training, and features, making it complex and slow.
MetaDefender should have a wizard or general policies that can be used for 80 percent of customers.
Cyber Security Architect at Diffiesec
Pricing is an important aspect in catering to customer budgets and is a must-have consideration for organizations.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
Enhanced reporting and audit capabilities are not fully utilized.
Project Engineer at i-Secure Networks & Business Solutions Inc.
 

Setup Cost

MetaDefender's high price is justified by advanced features and is favored by enterprises needing strong security and integration.
When someone attempted to buy from us one instance of OPSWAT, it was about nine thousand dollars for multi-scanning with eight engines and also the CDR module.
Cyber Security Architect at Diffiesec
The price varies based on deployment types; we only used it for file transfer and cloud integration rather than email, which kept it within our budget.
Senior Associate at a educational organization with 11-50 employees
Regarding pricing, setup cost, and licensing, I find the pricing for kiosks, cloud, deep CDR, and adaptive sandbox appropriate.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
 

Valuable Features

MetaDefender excels in multi-engine scanning, threat removal, and usability, enhancing data security with CDR and sandbox analysis.
NetWitness NDR offers high detection rates, real-time malware response, third-party integration, and a user-friendly, interoperable interface with advanced analytics.
I believe this is very effective and is the most effective engine of OPSWAT because customers ask for OPSWAT for two main reasons: the CDR capabilities and the multi-scanning engines.
Cyber Security Architect at Diffiesec
MetaDefender's core philosophy of trusting no file means it scans files, rebuilds them, and verifies their reputation, ensuring they contain no malicious content.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
The integration of multi-scanning and Content Disarm and Reconstruction is truly helpful because we can utilize it in other products such as email integration with ICAP capability, and we are also using it in web scanning.
Project Engineer at i-Secure Networks & Business Solutions Inc.

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.

Reliable and good support but can be expensive
I have no real complaints about the solution. Threat detection could be better. They need to enhance their threat intelligence feeds. We would like to have more IOCs or more trade intelligence to not only rely on the intelligence of the engineer in charge but to have some threat intelligence and some seeds of IOCs and to have the host have some artificial intelligence to reduce the number of false positives. I don't see this solution being very scalable. The solution is pricey.
