Featured Reviews

Mahmoud Younes - PeerSpot reviewer
Reliable installation and diverse use cases provide strong value
IBM Security QRadar has some areas for improvement. We have missed some DSM components. We need to customize logs where there is no DSM or connector for certain products. We can integrate but we have missed the DSM, which is the connector to pass logs coming from different applications. For example, with a university customer, we tried onboarding Canvas service. IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
Syarul Idzuddin Adzmi - PeerSpot reviewer
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

"It is a pretty solid product for the type that it is representing. It is a CM solution as compared to Splunk or ArcSight from HP. It is also user friendly. It comes with some internal AI as well, in which it automatically maps multiple lots from unrelated devices and makes a smart decision to link them back and create an offense based on that. It is a smart tool."
"This solution provides me with various alarms, and I have found security issues with some of my other products."
"The product can scale."
"The solution is reliable."
"We've found the technical support to be very good."
"I think the QDI is very good."
"The UBA feature is the most valuable because you can see everything about users' activities."
"I really like the feature we have with the logs, that if there are any credit card numbers being used, like a PII, you can just use rejects and you can mask it. This is a really good feature in QRadar."
"The product is scalable."
"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."
"The initial setup of Nagios Log Server was easy and straightforward."
 

Cons

"Ideally we would like a mobile version so that any alert that comes in will notify us in a mobile app, or by using SMS integration."
"The reporting system could use some upgrading."
"The IBM support can be better."
"The tech support is not that good."
"I need a solution which will send alerts in the event of any behavior."
"QVM is another instance where they need to revise the vulnerability scoring and the proper remediation details."
"IBM technical support is always terrible."
"I would also like to see more integration with other vendors. IBM doesn't integrate well with products from China, like Huawei. Many Middle Eastern customers are switching to Huawei from American vendors like Cisco because of the price. In most RFPs, Huawei wins because it costs less."
"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. 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 support could be better."
 

Pricing and Cost Advice

"The solution has a licensing model that is based on events per second so it scales to need and budget."
"The solution is costly and the price differs depending on the vendor you use."
"Licensing can be costly depending on your architecture."
"The pricing needs to be such that they are more competitive with other vendors."
"It's not expensive for the resources that it gives you."
"It would be great if this product were cheaper."
"Customers have to purchase a license based on the number of users, devices, and applications they want to protect. It allows you to take a license on a subscription basis for three years or five years."
"It is a perpetual license that we have for the event collector. The licensing is done based on the number of events and flows that you receive on this particular device. These are perpetual licenses, which means once you purchase them, they don't expire, which means that the support to IBM is definitely renewed after every one year. We have an enterprise agreement with IBM, which puts the cost in a totally different category as compared to someone who is not an IBM partner and is approaching IBM for this solution. We were able to get massive discounts. To give you an idea, we recently purchased 30,000 event licenses, and it costs around $480,000. It is definitely not a cheap product. We have licenses for about 270,000 events per second and 3 million flows per second. All the appliances and their events and flows are basically clubbed together and charged or rather calculated through a single source. The console receives all the details from all the event processes that we have globally. So, the license that we have is a single license for 270,000 events per second and 3 million flows per second, but that can be managed centrally. I was only part of the secondary purchase, which was 30,000 events per second for about $480,000. You can calculate how much we paid for 270,000 events. Reducing its price would be a compromise. We have already used a lower-priced product in the form of NNT, but we had to get rid of it because it was not doing the job that we actually wanted to do. You get what you pay for."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"For a single instance, the price is around $4,000."
"We found the pricing to be quite affordable."
