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.

"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, and if there are aspects that are missing IBM add them in the next release."
"The most valuable feature of Splunk is the management and built-in workflows."
"Searches logs from all devices and gives valuable information to the organisation, so it can drill down on all reports and security threats."
"We can do things in minutes instead of days."
"Splunk Enterprise Security is able to process a huge amount of data without any issues."
"On the cloud, we are pushing through less than half a petabyte of data. So far, it has been fairly stable because it runs on all the underlying AWS infrastructures."
"The initial setup is pretty straightforward."
"Our clients are easily able to modify and evolve their implementations."

Cons

"The dashboard could improve in IBM Watson for Cyber Security."
"They need to continue to build the AI capabilities."
"They need to continue to build the AI capabilities."
"In the future, I would like to see threat intelligence included."
"This is an expensive product, so making it more cost-effective would be an improvement."
"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."
"The dashboard could improve in IBM Watson for Cyber Security."
"While Splunk Enterprise Security is powerful, it presents significant complexity for users, as it's not particularly user-friendly for beginners."
"Due to the size limit, we could not see the full product."
"The administration of the cluster and app deployment to indexers or search heads can be done only using ssh access and command line, there is no GUI tools for that."
"Data retention can be better. If we want to look at the data for five months or six months, that is not available to us. We only have a history of 20 or 30 days. After that, the information gets lost. That is a drawback."
"The problem with Splunk Enterprise Security generally, from what I've seen in the last couple of years, is that it has a cultural, assumption design model around it, which means the company has to fit its internal processes in terms of how to use it."
"Splunk can improve regex/asset analysis as we do not want to crawl until it is done."
"Some of the terminology can be confusing, even for seasoned vets. Renaming components at this point would be a serious undertaking. However, it might be beneficial in the long run."
"Our organization has very limited resources, so we would want to expand some of those automation and AI capabilities to fill those gaps."
 

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."
"Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract."
"The variables and the flexibility that Splunk provides are helpful, especially in a hybrid and multi-cloud environment."
"ROI is estimated at saving my team roughly 10 to 12 man hours per week in troubleshooting for our company as well as what our profits had been from our services of installing, configuring, and supporting other clients with the product."
"Its pricing model can be improved."
"It's definitely worth it."
"I would highly recommend anyone evaluating this option to download the free trial which allows for the ingestion of 500MB of data per day in order to get a feel for what Splunk does at its core. It will get pricey once your ingestion rates start to sky rocket, but I would consider it expensive given the amount of information that it allows you to analyze and react on straight out-of-the-box."
"The price of Splunk is reasonable."
"Splunk Enterprise Security's pricing is competitive."
