A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

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

"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
"The initial setup of Nagios Log Server was easy and straightforward."
"The product is scalable."
"A great feature of the solution involves its internal portal."
"Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language, allowing extensive customization and analysis capabilities."
"My customer was integrated with many third-party credentials and other threat sources as well. The integration part was seamless and easy. The rates for allocating valuable information and IOCs from different sources are also good."
"Correlating data across different systems via one interface will allow you to know your environment or identify incident data in ways you never imagined."
"The most valuable features of Splunk Enterprise Security are the enterprise search bar and the dashboards."
"Overall, Splunk is among the top three SIEM tools due to its capabilities and agility in bridging business analytics with security needs."
"The fact that Splunk is a platform and not just a SIEM solution is a key benefit."
"Splunk Enterprise Security is probably one of the first products that actually could handle all the ingest and do all the correlation without crumbling under its own weight."
"Splunk has significantly reduced the time in performing the task of aggregating logs, reviewing as well as time spent during investigations."
 

Cons

"The support could be better."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"It is a challenge to manage the environment in such a way, that one’s log, even with the bandwidth license, isn’t exceeded."
"The cluster environment should be improved. We have a cluster. In the Splunk cluster environment, in the case of heavy searches and heavy load, the Splunk cluster goes down, and we have to put it in the maintenance mode to get it back. We are not able to find the actual culprit for this issue. I know that cluster has RF and SF, but it has been down so many times. There should be something in Splunk to help users to find the reason and the solution for such issues."
"I do not like the pricing model. It is expensive."
"They should make data onboarding easier."
"If you monitor too much, you can lose performance on your systems."
"The level of scalability depends on the license you have. You can expand or reduce it based on the environment. It does cost more money to scale, however."
"The prices are complicated as we operate in a small third-world country."
"I've noticed that onboarding data from various multi-cloud sources and diverse products, such as security network devices, can be challenging."
 

Pricing and Cost Advice

"We found the pricing to be quite affordable."
"For a single instance, the price is around $4,000."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"It's definitely worth it."
"Splunk is costly but it’s worth it due to the high-end features."
"My customers have found the price of the solution to be high."
"The price of Splunk Enterprise Security fluctuates based on the customer, but I believe it's quite costly, especially for our clientele."
"Splunk has always been on the expensive side."
"We had a yearly subscription."
"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."
"The pricing of Splunk Enterprise Security is somewhat high, but comparing it with its benefits, it's acceptable. It depends on the type of business."
