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.

"From what I have seen so far, this is an excellent product."
"The customer support is very good."
"The most valuable features of IBM Watson for Cyber Security are ease of use and out-of-the-box reports and compliance policies. Additionally, if there are aspects that are missing IBM add them in the next release."
"The integration is seamless with many devices and operating systems."
"The features I appreciate the most in Splunk Enterprise Security are the scheduled alerts and the search function."
"It's better than IBM, in my opinion, because it's an independent entity."
"The pricing, setup cost, and licensing for Splunk Enterprise Security are much better than McAfee, as it is more affordable and seems to be more robust and powerful."
"Splunk Enterprise Security is a very useful application to collect all the logs and also to find out the problems. You can easily create whatever you want by using its features, and it also has the capability to collect from all kinds of different platforms. Splunk Enterprise Security provides me with all the alerts."
"Splunk Enterprise Security is fast and well-documented, and user interface and user interaction are well-designed compared to other SIEM solutions."
"We can present to our management in real time the security of the batch management for the PCs, security regarding the network equipment. We're currently working in the Azure Cloud project, so we can send any logs from the cloud to Splunk. We can monitor them and we can present to the managers and customers. It's a very good solution for reporting. We use Splunk for reporting and monitoring of any solution in the company."
"Explore Splunk. The product has a lot of depth."
 

Cons

"They need to continue to build the AI capabilities."
"The dashboard could improve in IBM Watson for Cyber Security."
"This is an expensive product, so making it more cost-effective would be an improvement."
"In the future, I would like to see threat intelligence included."
"Make it easier to include roles and user controls, as it is horrible now."
"We find that the maintenance process could be a lot better."
"Splunk should align its security principles with those of other vendors like SentinelOne. Splunk has mature APIs that can communicate with various security applications and devices. Splunk can process more to produce an understandable dashboard."
"Splunk needs local technical support."
"The learning curve, its implementation, and its pricing are quite heavy for learners or purchasers."
"From the commercial point of view, they have to bring down their costs. It's a bit pricey right now."
"Its reporting can be improved. That's the only complaint I have heard. I don't need the reporting part, but I know that other people in the organization need it."
"Areas for improvement in Splunk Enterprise Security include enhancements to the dashboard and reporting features, as well as better handling of queries during peak times and improving self-monitoring dashboards."
 

Pricing and Cost Advice

"IBM Watson for Cyber Security is very simple to license and is priced well."
"The price of this solution should be lower, although I understand why IBM charges a premium price."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
"It can be expensive, especially the licensing costs. However, there is added value in what it can do, not just log aggregation."
"I am fine with the licensing, but in terms of the cost, it is expensive for the data that we have. We have an open discussion with our account rep about this."
"Splunk is priced higher than other solutions."
"While Splunk is more expensive than other solutions, we would still choose it because of its capabilities."
"Splunk Enterprise Security's pricing is pretty competitive."
"The tool's licensing is good and we haven't received any complaints from the team handling it."
