Comparison Buyer's Guide

Executive Summary

Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
6.6
Nagios XI enhances efficiency and time management but concerns about increased costs affect ROI perception across organizations.
Sentiment score
6.4
Splunk Enterprise Security boosts efficiency, reduces costs, and enhances visibility, providing significant ROI and improving security posture.
The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
We couldn't calculate what would have been the cost if they had actually gotten compromised; however, they were in the process, so every investment was returned immediately.
On average, my SecOps team takes probably at least a quarter of the time, if not more, to remediate security incidents with Splunk Enterprise Security compared to our previous solution.
 

Customer Service

Sentiment score
6.5
Nagios XI support is mixed; praised for responsiveness but criticized for high cost, complex licensing, and delayed responses.
Sentiment score
6.3
Splunk Enterprise Security offers expert support, though response speed varies; the online community and documentation enhance user experience.
We have paid for Splunk support, and we’re not on the free tier hoping for assistance; we are a significant customer and invest a lot in this service.
I have had nothing but good experiences with Splunk support, receiving timely and helpful replies.
We've had great customer success managers who have helped us navigate scaling from 600 gigs to 30 terabytes.
 

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
7.4
Splunk Enterprise Security is praised for effortless scalability, effectively managing increased data demands for both cloud and on-prem environments.
If the user interface isn’t presenting data well, it becomes difficult to manage when scaling.
We currently rely on disaster recovery and backup recovery, which takes time to recover, during which you're basically blind, so I'm pushing my leadership team to switch over to a clustering environment for constant availability.
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.
 

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
7.5
Splunk Enterprise Security is stable and reliable, with occasional performance issues linked to configuration or resource constraints.
It is very stable.
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
Splunk has been very reliable and very consistent.
It provides a stable environment but needs to integrate with ITSM platforms to achieve better visibility.
 

Room For Improvement

Nagios XI's interface is outdated, lacks scalability, needs better cloud integration, APIs, automation, and improved documentation.
Splunk Enterprise Security needs enhanced UI, simpler setup, better training, flexible pricing, improved integration, permissions, AI, and dashboards.
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.
For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.
 

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 yet valued for robust features; best for larger firms despite complex cost management.
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.
I find it to be affordable, which is why every industry uses it.
 

Valuable Features

Nagios XI provides customizable, flexible, and scalable IT infrastructure monitoring with real-time alerts and extensive plugin support.
Splunk Enterprise Security offers robust log management, analytics, and integration, enhancing threat detection, monitoring, and operational efficiency.
Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
The alerting system is very effective.
This capability is useful for performance monitoring and issue identification.
I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great.
Splunk Enterprise Security provides the foundation for unified threat detection, investigation, and response, enabling fast identification of critical issues.

Featured Reviews

Amir  Said - PeerSpot reviewer
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.
Kyle Vernham - PeerSpot reviewer
Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
