Real-time incident detection and user-friendly dashboard benefit daily operations
There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement. So far, it seems very limited. It shows some good features in the correlation part, but I think there is room for improvement. For instance, when creating rules, it can suggest more rules, reducing the effort needed. If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules. Sometimes logs I receive don't mean anything, and I need technical stakeholders to share or forward logs, but these are sometimes inadequate. Keywords can help identify insufficient logs. I often lack time to verify logs. Sharing false positive results could be reduced to help my team.

Really scalable for enterprise customers
The solution should have more integration capabilities with different platforms. The API is nearly open and scalable, so the solution can integrate with many platforms. The solution has more than 200 log sources in the scalability to support, but this is its limit. Installation is pretty easy. However, there are a couple of modules involved, so it is not as easy as it could be. We are talking about a distributed module, not a single-module type. This is what makes things a bit complex, instead of easier. I rate it as a seven out of ten on its installation and configuration capabilities.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

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

Pros

"It showed us where weaknesses were in our environment, so we could actively target those patches first."
"The feature that I have found most valuable is how it monitors the real network. That is its leading security feature."
"There is a single dashboard that gives us a complete overview of what is happening around the globe."
"I have found visibility very helpful for analytics."
"Senses, tracks, and links significant incidents and threats."
"I think it's a very stable product that provides much more visibility than the other product."
"The most valuable thing about QRadar is that you have a single window into your network, SIEM, network flows, and risk management of your assets. If you use Splunk, for instance, then you still need a full packet capture solution, whereas the full packet capture solution is integrated within QRadar. Its application ecosystem makes it very powerful in terms of doing analysis."
"The scalability is good."
"What we are mainly using are the RSA concentrator, RSA Decoder, Archiver, Broker, and Log Decoder."
"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."
"Alerting Module: It provides real-time event processing language on all the logs/packets stream for advanced alerting, i.e., using SQL LIKE statements."
"The solution is really scalable for the high-end power, enterprise customer."
"The most valuable feature is the security that it provides."
"The most valuable feature is the hunting ability to work in a CERT."
"Offers a good wireless feature."
"The software is scalable to whatever is required, and you can also put a lot of resources in the cloud."
"Splunk Enterprise Security enhances business resilience and assists with threat detection by centralizing security data."
"They are a good partner for Google Cloud. It provides great visibility, threat detection, and proactive mitigation of risks for our mutual consumers."
"The ability to analyze huge amounts of sales data and accurate prediction of sales forecasting is the most valuable feature."
"The incident review pane is the best part of it because that is where the SOC lives. It is the heartbeat of what the SOC needs to do. You are able to start the investigative process. As you are sitting in the incident review pane, you see the alert, and from that one alert, which is called a notable alert, you can drill in and see all the different specific details that are tied to that."
"Our clients are easily able to modify and evolve their implementations."
"Splunk's strongest suit is its user interface. We can integrate multiple solutions and adjust settings in the Splunk interface."
"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."
"It is very scalable."
 

Cons

"For future updates, I'd like to see more advanced threat intelligence features integrated with AI. This would help with analyzing traffic patterns and improving protection. QRadar currently doesn't integrate with AI for threat analysis. However, AI could enhance its capabilities by learning traffic patterns and automatically blocking or quarantining suspicious traffic. This would be especially useful when administrators are not actively monitoring. AI could help by analyzing incoming and outgoing traffic and adjusting policies accordingly."
"I don't look at only the features and benefits; I also look at the price. It is a bit expensive when compared with other solutions. It is expensive for specific deployment topologies, and the decision-makers go for alternatives like ArcSight. It should also have more AI features or capabilities for better threat intelligence. The more it uses machine learning, the better would be the dashboard, analytics, and other things."
"The implementation and configuration are not easy."
"Some of the cloud apps need improvement."
"We would like to see better instrumentation for debugging changes in the log flow."
"IBM QRadar Advisor with Watson could be more user-friendly. You need some skills and understanding of what you're looking at, especially if you're going to draw down specific information."
"You can scale IBM QRadar User Behavior Analytics, but it has room for improvement."
"I need a solution which will send alerts in the event of any behavior."
"Security needs improvement."
"Sometimes, it gives me static when integrating Windows-based systems. It should produce a precise log of sorts as to where the problem is. For example, a few days ago because of the McAfee application firewall, I couldn't get access to the particular Windows machine. So, my team and I had to figure out by ourselves that there was a virus responsible for the obstacle. This solution should trigger a meaningful log or message indicating the reason the user or implementer can't get into the machine."
"There is no support for this product in this country, so problems have to be resolved through global technical teams."
"More customizability is required, which is something that they need to improve on."
"The implementation needs assistance."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"The log system is a bit complex and has room for improvement."
"We have encountered issues with unresolved crashes."
"Splunk Enterprise Security would benefit from a more robust rule engine to reduce false positives."
"Could be more user friendly."
"While Splunk Enterprise Security offers valuable features, its cost is high and could be more competitive."
"Cybersecurity and infrastructure monitoring have room for improvement."
"You do need a lot of training and certification with this product."
"We are waiting for Dashboard Studio to mature a little bit more. There are some things that we are using with Classic Dashboards which have not yet made it to Dashboard Studio. We are waiting for that."
"It needs integration with a configuration management solution."
"Splunk Enterprise Security provides us with the relevant context to help guide our investigations, but it would be interesting to add even more context, for instance, in order to raise the level of risk."
 

Pricing and Cost Advice

"IBM's Qradar is not for small companie. Unfortunately, it would be 'overkill' to place it plainly. The pricing would be too much."
"We pay approximately $40,000 to use the solution annually. This solution is a lot less expensive than Splunk."
"As for licensing costs, I haven't seen the exact figures, but it is considered somewhat costly. On a scale from one to ten, where one is very expensive and ten is very cheap, I would rate it a six—it’s costly but worth the money."
"The tool's on-premise version is expensive. However, it is cheaper than Splunk. The hybrid model offers shared instances for customers, which is not expensive. Customers with a limited budget can opt for it. You can get premium support with licenses. However, if you need customized integration, you need to buy it."
"Pricing is good."
"This price is a little high, so it's an expensive product."
"It is costlier as compared to the other alternatives available in the market."
"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."
"This is a pricey solution; it's not cheap."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"Our license is for one year."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"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."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"It is cheap."
"We are on an annual license for the use of the solution."
"Splunk's costing is a little more difficult. The pricing method is complicated, and the way that costing is calculated in Splunk is a little more difficult."
"The pricing can be better. We are already considering Elastic because Splunk is too expensive. You have to pay based on per-day ingestion. There should be a more flexible model for the use cases where one day you have a huge amount, and on other days, it is quite less."
"The price of Splunk Enterprise Security is high."
"We had a yearly subscription."
"Our customers often complain that the price of Splunk is too high."
"Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract."
"It can be tough to determine if you are getting all of the value out of your investment at times."
"The price of Splunk is reasonable."
