Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.

A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight 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

"The simple user access model, or the user interface, is something that is very helpful."
"It provides many options for searching. I can see devices from different vendors, like Cisco, in one interface, which is good for me."
"The query search and log fetching are really helpful in IBM Security QRadar when compared to other tools."
"The simplicity of the solution is the best feature."
"The query search and log fetching are really helpful in IBM Security QRadar when compared to other tools."
"The most valuable features are: Auto update: QRadar will download new logs from the database on the supported security device, so that it will automatically normalize the new log format and you will not need to rewrite all your rules/offenses again."
"The most valuable features are log monitoring, easy-to-fix issues, and problem-solving."
"The most valuable feature is the integration with the GRD, for banking."
"A great feature of the solution involves its internal portal."
"The initial setup of Nagios Log Server was easy and straightforward."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
"A great feature of the solution involves its internal portal."
"The product is scalable."
"My company is a featured partner of Nagios XI, so I'm implementing Nagios XI in different companies and supporting the product, and I'd recommend the solution because it offers a lot of benefits and has a good dashboard, it's pretty easy to get up and running, and the pricing is good."
"One of the most valuable features is the dashboard because the UI was effective and easy to use."
 

Cons

"The price is very high."
"I would like to see more integration in place after the security lock."
"The technical support can be improved a little bit, and the price could be cheaper."
"It can have more integration. It should have more flexible RESTful APIs for integration with applications."
"The dashboard and reports are not user-friendly or efficient so are of little help with threat hunting activity."
"We sometimes get an error about the hard drive. Approximately once in two months, we can't find the logs, and they go missing, which is a terrible issue."
"The architecture could be improved. I got stuck for a long time trying to understand the architecture, as it is quite challenging."
"The threat detection needs improvement, they have many false positives."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The configurations during initial setup could be improved."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The support could be better. They only offer email support."
"The support could be better."
 

Pricing and Cost Advice

"The solution is priced fairly, there is a license for the solution, and we pay annually."
"When it comes to the initial pricing there can be a huge discount from there side and also I think they are open to competing with other products."
"found other solutions, with more features at the same cost or less. You don’t have to leave the Gartner Magic Quadrant to beat their price."
"QRadar UBA's price is a little more than street price and could be reduced."
"QRadar's price is reasonable compared to LogRhythm."
"The licensing is also overly complex, as there is a need to buy the work load performance monitoring separately."
"Licensing is very expensive, IBM QRadar is a very expensive solution. If you want to minimize costs then IBM QRadar is not for you."
"The solution's pricing is based on the EPS model."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"We found the pricing to be quite affordable."
"For a single instance, the price is around $4,000."
