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
Senior Manager at Bank of America
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

Pros

"The product is scalable."
"A great feature of the solution involves its internal portal."
"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."
"A great feature of the solution involves its internal portal."
"One of the most valuable features is the dashboard because the UI was effective and easy to use."
"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."
"It provides a risk score for each object, device, or user. We can then take action if they are at a higher risk."
"The solution helped reduce our alert volume."
"The most valuable feature of Splunk is the management and built-in workflows."
"It is very easy to use and integrate. There are connectors for every technology."
"The flexibility of the solution is quite good."
"The most valuable feature is the DSS, also known as SPL, because it allows users to script advanced queries with limited knowledge."
"Splunk provides a free version so you can test it before purchasing."
"Splunk setup is easy and straightforward. ​"
 

Cons

"The configurations during initial setup could be improved."
"The support could be better. They only offer email support."
"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."
"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 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."
"I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security to be cumbersome."
"Their technical support sucks."
"We do have to educate developers on how to not blow it up. It is a little to easy to write an expensive query and overly stress the system. This could be improved."
"Writing queries is a bit complicated sometimes."
"I would like more assistance with use cases and help with teaching us how to use it once it's installed."
"Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team."
"The prices are complicated as we operate in a small third-world country."
"The main improvement needed in Splunk Enterprise Security is its system visibility after installation."
 

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."
"Splunk Enterprise Security is a bit expensive overall, but it provides good value."
"Splunk is not a cheap solution and the license is billed annually."
"Pricing can be a limiting factor. You have to continuously tune what you are bringing in and make sure what you bring in is of value."
"The pricing is a little bit on the higher side, but looking at what Splunk provides us, it is reasonable."
"The license for Splunk Enterprise Security is expensive."
"It is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options."
