Great for PCI compliance but issues with stability and large amounts of data
I mainly use this solution to meet PCI compliance The automation of compliance reports and the correlation of the log have been major improvements.  The most valuable feature is the predefined reports for PCI compliance. The correlation suite needs to be improved. I also think they need to…

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

Pros

"The Change Tracker tool is very good and will reduce your overall workload."
"This is a very easy-to-use interface with a quick ramp-up time."
"The most valuable feature is the predefined reports for PCI compliance."
"The FIM features in the Change Tracker and the Log Tracker are the most valuable."
"If you want to deploy a SIEM and you want it to be simple, and not deal with much maintenance or help from the OEM, then I would say that NNT is the one."

Cons

"It is able to identify the vulnerability, however, they need an option to auto-mitigate."
"There are some issues with the stability - the correlation engine has failed multiple times, and the reports sometimes take too long, so we have to involve the tech team to get them."
"I would like to see the integration of AI technology, so rather than manually monitoring the logs, the tool will understand it and take care of it."
"For the NNT Log Tracker and Change Tracker, they have to make their knowledge base available online because there is very little information available on the internet."
"It is able to identify the vulnerability, however, they need an option to auto-mitigate."
"Only one minor deployment issue came up and it was resolved quickly. No other areas of improvement come to mind yet."

"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
