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 feature of this product is innovation, where the research and upgrading of technology never ends."
"The customer support is very good."
"From what I have seen so far, this is an excellent product."
"IBM Watson for Cyber Security is very stable."
"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."
"Splunk Enterprise Security has positively impacted our organization by helping to formalize our SOC program, enabling us to fundamentally respond to alerts as well as create detections around security events, and providing a single source of truth for our analysts to work out of instead of having multiple different platforms."
"Splunk Enterprise Security helped improve our organization’s ability to ingest and normalize data."
"It is lovely to have everything we need in one tool. Everything is quite centralized."
"Splunk Enterprise Security has positively impacted my organization greatly; without it, I don't even know how we had a SOC previously."
"The features of Splunk Enterprise Security that I prefer the most are risk-based alerting, the new Mission Control, and the integrations that are coming into place between Mission Control and Splunk SOAR."
"Splunk has enabled us to utilize many different data sources and is easy-to-use."
"Splunk Enterprise Security has positively impacted our organization by allowing us to use it on a daily basis, improving our security front and allowing our analysts to review and inform management on any trends, deficiencies, and necessary areas of improvement."
"It gives us good visibility into multiple environments, including cloud, on-premises, and hybrid; irrespective of platform."
 

Cons

"They need to continue to build the AI capabilities."
"In the future, I would like to see threat intelligence included."
"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."
"It can be tough to determine if you are getting all of the value out of your investment at times."
"Since I am currently working with SOAR, I would like to give recommendations regarding Splunk SOAR, as there are very few ready-made apps, and we face problems with integration, which requires us to write to the vendor for help."
"The support is not so good, I would only give them a rating of six or seven."
"However, for smaller organizations, the deployment and management can be expensive, leading them to choose other SIEM tools."
"They should put out more educational resources for users to learn how to use Splunk Enterprise Security."
"If you monitor everything, everything stops working."
"The way Splunk Enterprise Security could improve is by pulling in and mapping my DHCP data and tracking users' IP addresses as it changes throughout sessions, and being able to keep track of who is actually assigned to what IP address more natively."
"Beyond support, the pricing tier of Splunk Enterprise Security could be better, as it is an expensive solution; however, the cost reflects the value delivered."
 

Pricing and Cost Advice

"The price of this solution should be lower, although I understand why IBM charges a premium price."
"IBM Watson for Cyber Security is very simple to license and is priced well."
"The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application."
"The subscription is monthly."
"Splunk is really expensive."
"Splunk Enterprise Security is affordable."
"Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk."
"Splunk can be an expensive solution. It all depends on how we configure the alerts and the events from the endpoints. You can save some money if you do that correctly. If not, it becomes an expensive solution."
"Splunk Enterprise Security is expensive. I would rate the cost an eight out of ten with ten being the most expensive."
"We had a yearly subscription."
