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

"QRadar, Splunk, and ArcSight are SIEM solutions with built-in AI/ML features. They can do the complete investigation and alert the admin about what is happening. They can also do the root cause analysis. There are many other features that come with QRadar. It has a more granular log, so you can integrate with various non-IT as well as IT-based components. You can get unstructured data to the SIEM data, and you can identify more what is happening in the network or what is happening in the central head office. You can also identify what is happening between your remote offices. You can also use it to identify what the users in the field are doing on their devices and how things are moving. From the integration point of view, it is very centric. It gives complete control centrally. If a user is not connected to the system, whenever he comes online, we can see the policy updates over the Internet, and we can ensure that the data that is supposed to be protected is protected."
"It is suitable for large companies with critical infrastructure. For our clients, robustness, availability at a high level, and the level of references and experiences connected to the solution are important."
"It integrates very easily with other solutions. The solution is flexible. We can add anything to it, as it is a good companion to other tools."
"The timeline and machine learning features are great."
"We have worked with other solutions, such as LogRhythm and Splunk. Compared to others, IBM QRadar has the best price-performance ratio so that you are able to reserve minimum costs. It starts settling in fast and gets the first results very quickly. It is also very scalable."
"The UBA feature is the most valuable because you can see everything about users' activities."
"The feature that I find the most useful is that IBM QRadar User Behavior Analytics is free of charge. It's a fully free product that can be installed on top of IBM QRadar SIEM."
"It provides many options for searching. I can see devices from different vendors, like Cisco, in one interface, which is good for me."
"The initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
"The product is scalable."
"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."
 

Cons

"Do your research before implementing it, because it is tough to implement."
"The interface is very old. IBM should remake it into a more modern interface."
"Technical support could be improved by a bit."
"The AI engine could be smarter."
"The AQL queries could be better."
"I would like to see some artificial intelligence and alternative solutions."
"The costing part could be improved."
"I have noticed the interface has room for improvement."
"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."
"The support could be better."
"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."
 

Pricing and Cost Advice

"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."
"I think that the price is fair, but we can always say that the price could be cheaper."
"We use QRadar as a managed service and we pay licensing fees to the partner."
"The pricing is higher but cheaper than others and there are no additional costs."
"There are additional costs, such as the cost associated with the different hardware required for implementation and deployment. Along with the add-on apps, these are all additional costs, and they require licensing as well."
"It's very expensive but it fits our budget."
"It's too expensive. The licensing is also a little bit difficult to understand because you have to license it per event and per number of flows."
"The license is not subscription-based."
"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."
