Muhammad Anas - PeerSpot reviewer
Provides a memory utilization graph and shows disk space and uplink utilization but could include smart navigation in next release
The solution is deployed on-premises. There are more than 20 people who use this solution in my organization. They're infrastructure engineers, network engineers, and information security engineers A great feature is the memory utilization graph. It shows utilization, disk space utilization,…

Beneficial single unified dashboard, good native application integration, and high availability
My advice to those wanting to implement RSA NetWitness Network is they have to first do a little due diligence, such as the exact requirement based on their needs. That will give them a direction for their investment because otherwise, the bill of material or bill of quantity (BOQ) may be higher side. It is important to do good due intelligence on the environment, see the exact requirement, and then go ahead with the solution. The solution is perfectly stable. I rate RSA NetWitness Network a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"A great feature is the memory utilization graph."
"The feature that I have found the most useful is the decode of packets. It gives us a variety of information that helps us in figuring out what to look at. The networks are getting really complex, and without the information that we get from Iris Session Analyzer, we couldn't do our job. Its graphical user interface is also very easy to use and intuitive."
"NetWitness Endpoint's most valuable features are its interoperability across many different operating systems and the ease of pivoting from network to endpoint via a single console."
"The stability of the RSA NetWitness Endpoint is very good."
"We've contacted technical support several times. They've been very good. They have been able to help us resolve our issues."
"It's a scalable solution. We have around five to eight customers using RSA NetWitness Endpoint, and we hope to increase the number of users."
"It helps our security team respond more accurately when there are threats, then we get less false positives or negatives."
"It is very easy to use, and its usability is great. The use cases are also very easy. The visualizations of the use cases are magnificent. You cannot find this in any other solution. From my point of view, it is great."
"It is stable. We have been using it for some time, without any issues."
"RSA NetWitness does market analysis in a more granular form. It gives you full visibility."

Cons

"They can increase flexibility in the search engine. Basically, I go with the information I have at the time. If I could just type in the parameter that I want to search for and its value, it might be easier than having to do the groundwork upfront before I can get my traces."
"Sometimes the network analyzer will show that a server is down when it's actually working."
"Its price could be improved. It is an expensive product. Its training is also too expensive. It would be great if they can have a better pricing scheme for the training."
"The threat intelligence could improve in RSA NetWitness Endpoint."
"The initial setup requires a high level of skill."
"The integration of the solution needs to be improved. The dashboard needs lots of updates as well. In the next release, we would like to see advanced fraud detection features."
"The deployment process is complex. I don't know why, but this solution will suddenly stop working. Logs stop coming. Often, one thing or another stops working. Most of the time, one of my team members is working with troubleshooting and working with technical support. Log passing is also one of the biggest challenge."
"The solution is modular, for example you can buy the RSA ePack, which you buy as a module is not part of the conduit solution. They could include it and have it as an all-in-one solution."
"The solution lacks a reporting engine."
"The contamination feature could be improved."

Pricing and Cost Advice

"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
"I do not have any opinion on the pricing or licensing of the product."
"With RSA, there is flexibility in choosing the service, products, and the range that meets your requirement, as well as they are flexible in terms of pricing."
"It is an expensive product."
"We are on a three-year contract to use RSA NetWitness Network."
"The pricing is not very economical. It is a quite costly product for India. One thing is that when you purchase it, you have to purchase a module separately."
"The price of the solution depends on the environment. If the environment is large then it will cost more. However, the larger the environment with more endpoints, you will receive an increased discount. If the environment is very small, then you might think it is expensive. It is always better to buy in bulk to receive a discount. The minimum number of assets is usually 500, with discounts on 1000 and 2000."
"It is highly scalable. It can be bought based on your requirements."
"The cost depends on the number of endpoints that you want to monitor, but it is not expensive."
