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.

Improved threat detection and incident response has revealed training and usability gaps
What I would like to add is that if the interface or if there is less to work on technical knowledge. For example, people with no technical knowledge cannot use this, so they need to have at least a deep or substantial level of technical knowledge to be able to use these tools. If there is a way there can be an optimization to accommodate those with no technical knowledge in the process using tools compared to tools such as Sentinel and Splunk, which also doesn't require much technical knowledge to be able to use. That would also help. I think Security Onion could be improved by making the user interface more intuitive for new users and simplifying the initial setup and configuration process. Security Onion needs to be simplified so that those with less technical knowledge can be able to come in and use it. Guidance on prioritizing alerts will also be helpful, especially in an environment where security analysts deal with a high volume of security events. I also would like to mention that it needs to be more straightforward integration with other security tools. There needs to be a handshake between Security Onion and other same tools to help in endpoint detection and protection against threats. Another improvement that could also enhance is the reporting and visualization of the key metrics such as detection time, the incident, the overall interface of the analysis, and the false rate, which will also give Security Onion a better view for security analysts to be able to use and understand it. I would like to see the interface to be more simplified. I also would like to see the visualization to be more improved. I also would like to see the support features to be something that junior analysts or those coming in to start up their careers can be able to use without needing deep technical knowledge.

Quotes from Members

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

Pros

"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."
"The initial setup of Nagios Log Server was easy and straightforward."
"A great feature of the solution involves its internal portal."
"We use Security Onion for internal vulnerability assessment."

"Security Onion has positively impacted my organization by enabling students to analyze logs, understand network traffic, comprehend intrusion detection, and utilize threat hunting and incident response skills in a practical environment, which are best practices we have implemented with the students."
"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."
"What I appreciate most about Security Onion is that it combines multiple security monitoring tools into one platform."

"The support could be better. They only offer email support."
"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."

"Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use."

"The product is not easy to learn."
 

Pricing and Cost Advice
