A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

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 features are the integration and ease of use."
"The most valuable feature is the ability to write rules and triggers for network communication and then being able to investigate based on that, where you can see the payload and deconstruct the packets."
"The development of use cases on the SSA console is quite user friendly, which means that the security analyst or the researcher does not have to learn another language."
"Technical support is very good; they try to resolve issues with the proper SLAs which are defined by them and they understand the client's requirements as well as the client's infrastructure in a better manner."
"Overall, this is a good solution with suitable features and it very well fits our needs."
"Over time, NetWitness Logs and Packets has matured from a boxed solution with multiple parts to the current, more streamlined version for which we only need the software license to put it up on our own cloud and deliver it to multiple clients."
"The detection of ransomware in the internal network has benefited my organization."
"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."
"We use Security Onion for internal vulnerability assessment."
"Security Onion is the most mature solution in the market."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"The initial setup is very complex and should be simplified."
"The multi-tenant capabilities are lagging compared to IBM QRadar."
"It is overly complicated. It has taken years to implement and the return on investment just isn't there."
"The system architecture is complex and sometimes it’s hard to troubleshoot potential problems."
"It is not so easy to customize this product."
"The initial setup was complex because it takes a lot of time to complete the implementation."
"More customizability is required, which is something that they need to improve on."
"We have encountered issues with unresolved crashes."
"The initial setup of the solution is a little bit difficult."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
 

Pricing and Cost Advice

"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."
"Our license is for one year."
"The licenses are good but the cost is very expensive."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"Compared to the competition, the is price is not that high."
"The product price was reasonable for my region and the market."
"Security Onion is a free solution."
"It is an open-source solution."
"Security Onion is an open-source solution."
