It is a stable solution, but they should make the user interface easier to understand
The solution's initial setup takes work. We have to organize multiple paths and many features. The deployment process takes less than a week. But it takes a month to complete if we want to make the solution smarter by integrating it with various devices. I rate the process as a six out of ten.
Hrishiraj Bhattacharjee - PeerSpot reviewer
Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"The most valuable feature of RSA NetWitness Logs and Packets are the alerts and correlations tools."
"Offers a good wireless feature."
"It's quite economical compared to other solutions in the market."
"It gives the capability for the incident response team to correlate logs to identify any kind of problem like malware and incidents in a general sense, both for logs and packets."
"The most valuable feature is the hunting ability to work in a CERT."
"The most valuable features are the threat prediction and network forensics."
"NetWitness Platform is valuable for creating rules that the solution must detect."
"Possibility to investigate incidents based on logs and raw packets, such as extracting files sent over the network"
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"Health monitoring of the event sources and devices."
"The multi-tenant capabilities are lagging compared to IBM QRadar."
"The initial setup is very complex and should be simplified."
"The documentation is not as structured as I would like, personally, and I think that it can be improved and made much more user-friendly."
"The initial setup was complex because it takes a lot of time to complete the implementation."
"The log system is a bit complex and has room for improvement."
"They should implement algorithms to digest that data and produce additional, more advanced reporting, alerting and support of internal security teams."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"This is a pricey solution; it's not cheap."
"Our license is for one year."
"Many clients are not able to purchase the packet capability because there is a huge amount of data, and the cost depends on the number of EPS (Events per second), as well as the number of gigabytes of data per day."
"We are on an annual license for the use of the solution."
"The licenses are good but the cost is very expensive."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"It’s a single license platform."
