Syarul Idzuddin Adzmi - PeerSpot reviewer
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

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."
"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."
"The product is scalable."
"A great feature of the solution involves its internal portal."
"The best features would have to be the ability to ingest any data and display it in a way that anyone can understand."
"The flexibility of the search capability is most valuable, and you can use it for more than just a basic log aggregator, which makes it powerful in that regard."
"The solution's most valuable feature is risk-based alerting, focusing on building out user risks for individuals throughout the enterprise."
"From a visibility perspective, the solution has significantly improved our organization by providing a single platform to visualize our entire IT landscape."
"It is very easy to use and integrate. There are connectors for every technology."
"Splunk is powerful when sorting huge amounts of data."
"The solution is very fast and succinct."
"The features of Splunk Enterprise Security that I find most valuable are the correlation and correlation data."
 

Cons

"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 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 configurations during initial setup could be improved."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"Splunk is very expensive. The license is based on the volume of the logs ingested. I was responsible for managing the contract with our service integrator. I don't know the precise details of the competing solution, but I have heard that Splunk is more expensive than others. I don't know what the going rate is on the market, but I think there are at least two competitors that are less expensive. We have experienced a few issues with our service providers in terms of log filtering and ingestion, so we continue to pay a bit more per day for our logs."
"It would be nice if they had a wizard to construct searches, including more complex searches that include math or statistics."
"Official training, even CBT, is expensive so not many people are able to get certified."
"The documentation and training resources available for knowledge and training can be expanded. We need to learn more about Splunk Enterprise Security and new security attacks."
"Splunk's implementation process for managing multiple indexes can be complex, especially when dealing with a large number of components."
"We usually have to follow up with technical support on our open cases."
"They can improve their support teams. They can also improve their capability of ingesting data from different IoT sources."
"Splunk could enhance its services by providing more comprehensive professional assistance aimed at optimizing our investment."
 

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."
"The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application."
"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 licensing model can be expensive, but the value it provides is significant."
"Splunk is expensive based on our current requirements, but it's obviously worth what we pay."
"It can be tough to determine if you are getting all of the value out of your investment at times."
"Splunk Enterprise Security is expensive."
"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
"From what I have seen so far, Splunk has multiple cost models. The one that we are using is pretty good when it comes to ingesting data into the environment. It has worked out pretty well."
