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.
Sathis-Kumar - PeerSpot reviewer

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 initial setup of Nagios Log Server was easy and straightforward."
"My company is a featured partner of Nagios XI, so I'm implementing Nagios XI in different companies and supporting the product, and I'd recommend the solution because it offers a lot of benefits and has a good dashboard, it's pretty easy to get up and running, and the pricing is good."
"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."
"A great feature of the solution involves its internal portal."
"A great feature of the solution involves its internal portal."
"The product is scalable."
"Explore Splunk. The product has a lot of depth."
"Regarding scalability, Splunk Enterprise Security is way ahead compared to other products, and I would score it at the maximum."
"The fact that Splunk is a platform and not just a SIEM solution is a key benefit."
"Splunk can deliver more information by going deeper. By creating a dashboard, we can identify the root cause of the threat. Let's say I have a firewall from Check Point. Splunk will find the dashboard for Check Point, implement it in our environment, and connect it to the Check Point firewall logs, which are shown on the dashboard. If we request a custom dashboard, the engineer will take longer to complete the task."
"We evaluated several solutions and selected Splunk due to the functionality and cost."
"The visibility is amazing with easy dashboard creation."
"The security part is useful as it helps secure the entire environment."
"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."
 

Cons

"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."
"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."
"The support could be better."
"The configurations during initial setup could be improved."
"The support could be better. They only offer email support."
"It would be good if the solution had some kind of copilot to automate or help write correlation searches."
"The threat management part is still lagging. There are some gaps in threat management. Other vendors have built-in threat management systems, but Splunk lacks the threat management component in its portal. The UEBA and everything else is perfect, but it lacks a unified threat intelligence and management part."
"There is improvement needed when importing from some types of data sources."
"The GUI can be improved. Splunk has always suffered from having a kind of goofy UI, it needs some updating."
"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."
"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."
"While Splunk Enterprise Security is powerful, it presents significant complexity for users, as it's not particularly user-friendly for beginners."
"The solution could improve by making it more business analysis oriented. The way it is now is designed more for developers."
 

Pricing and Cost Advice

"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"We found the pricing to be quite affordable."
"For a single instance, the price is around $4,000."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"Splunk has always been on the expensive side."
"Splunk is not a cheap solution and the license is billed annually."
"Free Splunk license for PoCs on personal machines and the ability to scale the PoC to an enterprise level app."
"This solution is costly. Splunk is obviously a great product, but you should only choose this product if you need all the features provided. Otherwise, if you don't need all the features to meet your requirements, there are probably other products that will be more cost-effective. It's cost versus the functionality requirement."
"The Splunk Enterprise Security license is expensive."
"Splunk ES is quite expensive compared to some products on the market."
"I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it."
