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.

Information Technology Security and Infrastructure Expert at a government with 201-500 employees
Helps to deal with potential attacks and is available at a reasonable price
My company has had many benefits from the use of the product in the last eight years. The tool has streamlined our company's incident response process since it serves as a log repository, which allows us to correlate events and access different technology stacks. In our company, we were able to actually find some potential attacks, so it has been very helpful. The tool's integration capability isn't so great. In my company, we managed to integrate it with our Microsoft Azure Subscription, after which we managed to integrate it with other tools. You will face a lot of difficulties if you want to integrate it with your database monitoring tool, PAM solutions, or IAM products. The product has done well overall for my company's teams to deal with their workflow efficiency. I would not recommend the product to others. I rate the tool a seven out of ten.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of IBM Security QRadar are flexibility, IBM support, and scalability."
"IBM QRadar is probably the best possible solution in the market."
"IBM Qradar's ability to simplify the number of events, not only on a technical level but by making that information easy to pan through the orchestration deduplication. It is very impressive given that we have hundreds of devices that send event logs through."
"I have found IBM QRadar to be stable."
"QRadar is built around Red Hat Linux, which is highly robust."
"We have evaluated Secureonix and this solution is far superior."
"Pulse, UEBA, and NBAD are the features that are the best, and they are the most useful from a SOC manager perspective."
"It comes with many rules disabled. You can tune them and modify them according to your enterprise needs and avoid false positives."
"RSA NetWitness is a SIEM and real-time network traffic solution that collects logs and packets, applies a set of alerting, reporting, and analysis rules on them, and thus provides the enterprise with full visibility of the networks and activities of the systems."
"Setting up NetWitness is straightforward. There are multiple connectors, including standard and specialized connectors. One purpose of the connectors is the enhanced capability integrate the custom applications. NetWitness comes with E6 appliances and application images that we use for the initial configurations and for the OS stack information. From there, you can consider the correlation rules, integrate the different log sources, and easily create correlation rules and backlog reports."
"The solution is really scalable for the high-end power, enterprise customer."
"The most valuable features are the packet inspection and the automated incident response."
"Integration is exceedingly minimal, since its project development is much easier than that of LogRythm or IBM."
"Prior to implementing the solution, the customers had no visibility of their assets, however, after adopting the solution, they have gained complete visibility over all their assets, including a comprehensive understanding of the network and attack symptoms."
"Offers a good wireless feature."
"Overall, it is easy to implement."
"The logs on the solution are excellent."
"It is a one stop shop as a full monitoring and alerting solution for operations and application analysis for most of our back-end systems."
"The user interface is excellent, and since I'm using Splunk as a power user, it's easy to create dashboards."
"Splunk Enterprise Security has helped reduce our team's average meantime to resolve metric by about 50 percent because we are able to tune it to lower false positives and noise."
"This is the right choice if you are looking for a platform that can combine all machine-generated data and use it for various use cases from different domains."
"Splunk Enterprise Security is fully scalable because it provides all kinds of configuration in management servers and all cloud integrations such as AWS, Azure, Google Cloud, Kubernetes, Docker, GitHub, Jenkins, and Cisco as well, and it is quite fully scalable across all platforms."
"Splunk Enterprise Security provides the foundation for unified threat detection, investigation, and response, enabling fast identification of critical issues."
"The solution's most valuable features are the granularity and analysis of the logs."
 

Cons

"The solution lacks vendor support."
"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."
"The price of IBM Security QRadar is an area of concern where improvements are required."
"The solution does not support the integration of flat file databases."
"I would like to see a better GUI."
"We actually have very few use cases and there were lots of false positives with QRadar."
"The technical support from IBM Qradar could improve. I rate the support from IBM Qradar a two out of ten."
"QRadar needs a lot of fine tuning"
"I cannot say that the solution was stable because it tended to crash."
"I'd like to see improvement in its ease of use. It's basically unusable. It's overly complex."
"One thing to be improved in NetWitness is the capability to correlate event logs in a general sense."
"The user interface is a little bit difficult for new users and it needs to be improved."
"I believe that integrating the solution with other products such as Oracle would be beneficial."
"We encountered stability issues in the earlier versions, and much fewer in the newer versions."
"Security needs improvement. We would still like to know how the traffic is entering the organization."
"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions. Whenever any hacking activity or any other threat factor occurred they used to provide the coverages very fast when comparing RSA NetWitness Logs and Packets. I heard the other three solutions, from a discussion with my team members who had experience in other solutions, they used to say that. Whenever any issues happened across the globe RSA NetWitness Logs and Packets are a little bit slow improving those detection mechanisms."
"Could be more user friendly."
"Splunk Enterprise Security is a costlier tool compared to ArcSight or IBM QRadar."
"Splunk is a very costly solution and I think it's the most expensive in the market in terms of costing."
"In my opinion, improvements in Splunk Enterprise Security could address the issue of unnecessary alerts. Sometimes we receive many false positives, leading to difficulties in identifying real security incidents."
"I would like to see the asset and identity lookups be more automatic and less manual."
"The level of scalability depends on the license you have. You can expand or reduce it based on the environment. It does cost more money to scale, however."
"Its initial setup is complex. You're going to need deployment services from somebody who is an expert in the product."
"We usually have to follow up with technical support on our open cases."
 

Pricing and Cost Advice

"There is a license required for this solution and it is an annual payment. I have found all solutions in the category to be expensive, including Splunk."
"Its price is good in terms of efficiency and the number of people required for implementing various things. You might pay more in terms of money, but you might save on the number of people. For example, if you are using Kibana, you have to pay more for people or experts, which is not the case with IBM QRadar."
"It is very expensive."
"The price of this solution is a little high."
"I think my company pays for the license yearly."
"It is costlier as compared to the other alternatives available in the market."
"The price of this product is high."
"IBM Security QRadar is a very expensive tool."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"It is cheap."
"Many clients are not able to purchase the packet capability because there is a huge amount of data, and the cost depends on the number of EPS (Events per second), as well as the number of gigabytes of data per day."
"The licenses are good but the cost is very expensive."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"It’s cheaper to run virtual machines in a VMware environment."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"Splunk Enterprise Security is an expensive solution."
"Most people share the same thought that the ingestion rates can get pretty pricey. There is a lot of work we do to curate the data that we send to Splunk so that it is not too noisy or too expensive."
"It is a pretty high cost solution, but if your organization has the funds, it can bring many benefits."
"The licensing model can be expensive, but the value it provides is significant."
"It is expensive. I used to buy it early on, but then they combined it into a higher-up organization. They buy it for multiple systems now. Last time, I paid around 60K for it. There is just the licensing fee. That's all."
"Personnel costs are saved by not having to involve the domain developers from multiple teams when tracing a problem that spans multiple platforms."
"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
"Splunk Enterprise becomes extremely expensive after the 20GB/month license."
