Partner Account Manager at a wholesaler/distributor with 51-200 employees
MetaDefender has positively impacted my organization by reducing the risk of file-based attacks, which has significantly improved our overall defense against phishing and malware delivery techniques.

MetaDefender's customer service is efficient, responsive, available 24/7, and highly rated for professionalism and knowledgeable support staff.
Sentiment score
7.3
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.
Cyber Security Architect at Diffiesec
When it comes to my communication with agents, I find they are responsive and professional.
Integration Technician at danet
Whenever we raise any support case, they provide complete structural descriptions and solutions to the problems we report.

Scalability Issues

Sentiment score
6.3
MetaDefender is praised for scalable deployments, handling traffic surges and large files, despite concerns over larger files and pricing.
Sentiment score
7.0
NetWitness NDR is scalable for large enterprises, though some users report issues with scalability and agent migration.
You need to do some sizing before installation and understand exactly what you are seeking from the solution and how it fits your organization.
Infrastructure Securiy & Cyber Engineer at El Al
We can increase the central management server by adding more CPU, RAM, and disks, and we can add more clients to the scan and create a policy for them.
Information Security Consultant at a tech vendor with 51-200 employees
MetaDefender is highly scalable and suitable for any growing organization of any size, with the main requirements being proper planning for traffic and security workloads.
SOC L2 Analyst at a tech services company with 51-200 employees
 

Stability Issues

Sentiment score
8.1
MetaDefender provides reliable performance with high availability, effective malware protection, and compatibility, despite occasional bugs and slow large file scans.
Sentiment score
7.7
NetWitness NDR is generally reliable, providing real-time data and stability, though minor technical issues are occasionally reported.
It protects mobile devices, an area where most other solutions have not been able to perform well.
Cybersecurity Professional at a tech vendor with 1-10 employees
MetaDefender has shown reliability in my experience with no downtime or reliability issues.
DevOps Engineer at Dynamic Solutions
The stability of the system is very high.
Cyber Security Architect at Diffiesec
 

Room For Improvement

MetaDefender needs UI updates, faster processing, improved integration, and cost efficiency for better user experience and management.
NetWitness NDR requires improvements in UI, scalability, detectability, integration, session times, pricing, training, and features, making it complex and slow.
I want to see enhancements allowing for automatic ticket creation using APIs to streamline the workflow and assign tickets to respective teams.
Packaged Application Development Team Lead at Accenture
My thoughts on its accuracy and reliability of output are that it relies on signature-based antivirus scan, which is not sufficient for AI-kind vulnerabilities or hacking.
Information Security Consultant at a tech vendor with 51-200 employees
The security information is useful, but making key metrics, detection trends, false positives, and remediation actions easier to understand would help a SOC team quickly identify areas requiring attention.
SOC L2 Analyst at a tech services company with 51-200 employees
 

Setup Cost

MetaDefender offers premium-priced, enterprise-grade features with customizable quotes; considered costly by startups but effective and flexible for enterprises.
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 Infra Architect 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 enhances security with multi-scanning, Deep CDR, and adaptive sandbox, ensuring threat elimination and content usability.
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.

Featured Reviews

Ravi Raushan Singh - PeerSpot reviewer
Senior Infra Architect at a educational organization with 11-50 employees
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.

Senior Cyber Security Analyst (SAFe Agile) at a transportation company with 1,001-5,000 employees
Advanced threat detection undermined by issues with blocking
NetWitness Endpoint's blocking feature does not work properly - if there's a malicious process, it's not possible to kill it via a custom rule unless and until it's flagged as malicious. For example, if you put IOCs in the form of hashes, it's not possible to block those IOCs - the system will alert you, but they can't be blocked. In the next release, NetWitness Endpoint should include regular expressions for blocking processes and sub-processes, the ability to block IPs, and scalability and integration with the ServiceNow platform or other ticketing solutions.
