Sentiment score
7.2
Splunk Enterprise Security boosts efficiency and ROI with enhanced insights and automation, despite potential cost concerns.
I have noticed a return on investment with Splunk Enterprise Security, as it delivers substantial value for money.

Nagios XI support is mixed; praised for responsiveness but criticized for high cost, complex licensing, and delayed responses.
Sentiment score
6.7
Splunk Enterprise Security support is generally positive, but response times vary, and complex issues may require escalation.
If you want to write your own correlation rules, it is very difficult to do, and you need Splunk's support to write new correlation rules for the SIEM tool.
They try to close issues as soon as possible, often just offering documentation links.
They are responsive and effectively resolve issues.
 

Scalability Issues

Sentiment score
7.1
Nagios XI is scalable for small to medium environments but faces challenges in large infrastructures and cloud adaptability.
Sentiment score
7.7
Splunk Enterprise Security excels in scalable performance, adaptable across environments, though scaling can increase costs.
If the user interface isn’t presenting data well, it becomes difficult to manage when scaling.
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
It is easy to scale.
It's big in a Central European context, and small from a Splunk North American context.
 

Stability Issues

Sentiment score
7.3
Nagios XI is stable, but large deployments may experience performance issues, database problems, and minor network dependencies.
Sentiment score
7.9
Splunk Enterprise Security is praised for its stability and performance, though updates and heavy usage can cause minor issues.
It is very stable.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
It is very stable.
 

Room For Improvement

Nagios XI's interface is outdated, lacks scalability, needs better cloud integration, APIs, automation, and improved documentation.
Splunk Enterprise Security struggles with UI complexity, costly licenses, integration challenges, setup complications, and limited customization and AI features.
Many tools have poor user interfaces, making them hard to manage and navigate.
The GUI could be improved. It's a bit too basic.
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
Splunk Enterprise Security is not something that automatically picks things; you have to set up use cases, update data models, and link the right use cases to the right data models for those detections to happen.
What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel.
 

Setup Cost

Nagios XI provides cost-efficient enterprise-level monitoring with reasonable pricing, appreciated for its features and open-source options.
Splunk Enterprise Security is costly for smaller businesses, with pricing challenges based on data volume impacting budget considerations.
We are using the free, open-source version.
The pricing for the Nagios XI product is good and better than other solutions.
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.

Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.
