Cyber Security Architect at Diffiesec
We handle vast amounts of traffic from banking, defense, and critical national infrastructure.
Partner Account Manager at a wholesaler/distributor with 51-200 employees

Room For Improvement

MetaDefender needs faster scanning, improved UI, better documentation, reduced false positives, easier setup, and more affordable pricing.
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 offers costly multi-layer security, seen as competitive, with $145,000 for three years including servers and support.
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
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
feedback indicates that our pricing is better than other vendor solutions.
Cybersecurity Architect at Natica IT Consulting
 

Valuable Features

MetaDefender offers comprehensive security with multi-engine scanning, sandbox analysis, CDR, file reputation, and seamless integration for enhanced data safety.
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.

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

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.
