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.
Carlos Snel - PeerSpot reviewer
Allows our IT department to easily analyze any connection issues
There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available. Additionally, more data centers are required globally to reduce latency, especially in areas like South America and Africa, though this does not directly relate to the Client Connector.

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 scalable solution."
"On the back-end, Watson helps me figure out an exact problem, sometimes giving me the result."
"The initial setup of QRadar is not complex because we have done it before and we are used to the development. It is getting easier all the time."
"The most valuable feature is the DSM Editor. The custom parsing tool is very nice, outstanding."
"It is incredibly easy to deploy. All the appliances are flexible in the roles that they serve and are all managed the in the same way."
"There are many things I appreciate about IBM Security QRadar; I haven't used any other SIEM before IBM Security QRadar, so for me, it is perfect."
"The threat protection network is the most valuable feature, because when you get an offense, you can actually trace it back to where it originated from, how it originated, and why."
"It has improved comprehensive visibility for what is going on in the perimeters, and on the inside, as well."
"The best features of Zscaler Client Connector are that it gives the client a much more transparent experience, as they don't have to worry about connecting to a VPN."
"The solution operates in the background seamlessly without the user noticing."
"I'd rate the solution nine out of ten."
"Zscaler Client Connector is quite scalable, and I would rate its scalability as nine or ten out of ten."
 

Cons

"IBM is going through some problems with its resources currently making its support response time slow."
"IBM QRadar has outdated technology, and this is its area for improvement. When you try to implement an analytic expression, it's not updated. The solution doesn't support newer technologies, and it doesn't update regularly. For example, around the world, others implement new technologies, while IBM updates later than others."
"The costing part could be improved."
"Do your research before implementing it, because it is tough to implement."
"There should be more opportunity for community kind of distribution where, for example, if there was a zero-day threat targeting companies."
"The only problem is that if you have too many events that occur, then the storage capacity becomes a problem. We would need to increase the storage capacity."
"The user interface is a bit difficult to get used to."
"I would suggest QRadar release any documentation or give an online demo, like videos on YouTube. It would increase publicity and public appeal."
"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."
"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."
"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."
"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."
 

Pricing and Cost Advice

"In terms of additional costs, it depends on the subscription that you choose. There are plenty of options to choose from."
"I would like for them to lower the price."
"The solution is priced fairly, there is a license for the solution, and we pay annually."
"When compared with other SIM solutions, QRadar is considerably less expensive."
"We use QRadar as a managed service and we pay licensing fees to the partner."
"IBM has subscriptions plans that run for one year."
"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."
"The solution's pricing is based on the EPS model."
