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.

It's not very attractive when compared to other solutions but the pricing is comfortable.
Log collection, and correlation engine usage. It has some limitations in parser modules. Comfort in pricing.  It's not very attractive in comparison to other solutions.  It needs to improve in AI and automatic parsing. One to three years.

Quotes from Members

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

Pros

"Splunk Enterprise Security offers valuable features like seamless integration and a SQL-standard Structured Query Language for easy searching."
"The solution's most valuable feature is its data modeling."
"We have seen a clear return on investment since we started using Splunk Enterprise Security; we get a lot of value from it for the business side."
"Splunk Enterprise Security offers excellent correlations, enhancements, and risk features that help my team."
"Splunk Enterprise Security has positively impacted my organization as it is a solid tool that gives us a great overview, and that overview helps my team by ensuring us that we are covered for cyber security attacks."
"Correlation search, in general, is valuable because it allows us to search multiple data sources easily."
"We see a lot of return on investment with Splunk Enterprise Security, as once implemented, it gives us a quick and responsive way of understanding alerts, which stands out compared to other solutions."
"Searches logs from all devices and gives valuable information to the organisation, so it can drill down on all reports and security threats."
"Comfort in pricing."
 

Cons

"One issue is that we are getting a lot of false positives. We are trying to reduce them by customizing the default rules, changing thresholds, and using white-listing and black-listing. It's getting better and better as a result. But they need to build components that would reduce the false positives."
"The solution could improve by making it more business analysis oriented. The way it is now is designed more for developers."
"The analytics of Splunk could be improved."
"I believe the areas of improvement for Splunk Enterprise Security would focus on resource utilization."
"The ticketing platform could be improved."
"The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side."
"Cybersecurity and infrastructure monitoring have room for improvement."
"The GUI should be improved, in other words, the overall appearance."
"It has some limitations in parser modules."
 

Pricing and Cost Advice

"It can be tough to determine if you are getting all of the value out of your investment at times."
"Although Splunk is an expensive product, it is designed to be utilized across your organization in order to maximize your ROI and lower your TCO."
"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
"Expensive compared to other options."
"In addition to the licensing fee, there is also a support and maintenance charge."
"The price is comparable."
"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."
