Operation Director at Digital Pulse Sdn Bhd
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

"The initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
"The product is scalable."
"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."
"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."
"The most valuable aspect of the solution is the ability to capture the different data streams."
"Analyst productivity has risen because they started using Splunk instead of the other product, the third-party SIEMs, and the detection has really improved because they are doing everything by SLA and fitting into these tight schedules, and our clients really love Splunk Enterprise Security."
"The best features and the most important feature I want to highlight about Splunk Enterprise Security is its capability to process large amounts of data."
"My security ops team takes around 30 minutes to one hour to remediate security incidents with Splunk Enterprise Security compared to a previous solution."
"Once you complete this setup, the product is amazing and will do all of the work."
"It is very easy to use and integrate. There are connectors for every technology."
"The correlation searches are most valuable just because we are able to do things like RBA."
"Splunk Enterprise Security performs 80% of our work on its own; we just have to do the remaining 20%, which gives us the freedom to explore and detect threats more effectively."
 

Cons

"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 configurations during initial setup could be improved."
"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."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The support could be better. They only offer email support."
"Splunk Enterprise Security Essentials has not contributed to a reduction in analyst burnout or fatigue."
"The first thing that comes to mind is a little bit of UI improvement. It sometimes can be a little bit buggy or it can be a little bit slow, but that varies from customer to customer."
"The integration could be a bit better. They charge for certain integrations."
"It can be tough to determine if you are getting all of the value out of your investment at times."
"I think the licensing costs for Splunk Enterprise Security are on the higher side, but I am not certain."
"I have concerns about the architecture as well since I can see it is not very well defined."
"The problem with the product is that the price of Splunk is very high."
"The amount of time it takes to troubleshoot not-easily-available data, and hours on the phone with VMware techs, have become an issue."
 

Pricing and Cost Advice

"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."
"We found the pricing to be quite affordable."
"Splunk Enterprise Security's pricing is competitive."
"We had a yearly subscription."
"The price of Splunk is too high for our market."
"It is a bit costly."
"I am fine with the licensing, but in terms of the cost, it is expensive for the data that we have. We have an open discussion with our account rep about this."
"Splunk Enterprise Security is an expensive solution."
"The Splunk Enterprise Security license is expensive."
"The cost is on the high end, which makes it difficult for some organizations to use."
