HarshBhardiya - PeerSpot reviewer
SOC Engineer at a outsourcing company with 10,001+ employees
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 best feature of IBM QRadar is visualization which shows you when there's a spike in the system, and this makes you realize that there's something wrong with the log."
"QRadar's stability is great because it is always live and is always catching and monitoring all the information that we need."
"Customer service is very good and very helpful."
"It has very rich functionality."
"This product helps us to find security incidents before they become a problem to the business."
"It showed us where weaknesses were in our environment, so we could actively target those patches first."
"The integration of third-party technologies with IBM Security QRadar is one of the high points they have; they integrate with almost anybody, anywhere, and there's an integrator tool for almost anything."
"Network-Based Anomaly Detection (NBAD): Using NetFlow, JFlow, SFlow, or QFlow (all 7 layers), offenses are detected as a response when a rule is triggered."
"The product is scalable."
"The initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
"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."
"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."
 

Cons

"It is not app based."
"The tool is very complicated."
"The GUI or graphic interface for IBM Security QRadar is neither good nor bad, but I hope for it to be more interesting, more live, and have better style."
"User/identity modeling needs improvement. Needs better visualization options beyond the time series charts and a few other options that they have."
"In terms of additional features, a mobile app would be nice. Also, the reporting is definitely okay, but you have to make sure that everybody with different roles can understand it. There is room for improvement in the reporting."
"There are several vulnerabilities that IBM is working with us on."
"IBM is going through some problems with its resources currently making its support response time slow."
"The dashboard is pathetic and it takes a long time to perform a search."
"The support could be better. They only offer email support."
"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 configurations during initial setup could be improved."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
 

Pricing and Cost Advice

"The price of this solution is a little bit expensive, so if it were cheaper then it would help."
"There is an annual license required for this solution."
"It is expensive. It is not a product that I can provide for SMBs. It is a program that I can only provide for really large enterprises."
"The solution has a licensing model that is based on events per second so it scales to need and budget."
"Licensing can be costly depending on your architecture."
"Pricing and licensing are competitive. Their new licensing options allow logs to bypass the correlation engine for a flat rate, which is also appealing for log data that is compliance-driven for a small amount of money."
"It's free of charge."
"Our licensing costs for this solution is on a yearly basis."
"For a single instance, the price is around $4,000."
"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."
