The open architecture is easy to extend and enhance
Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Centralized threat monitoring has improved visibility but demands complex setup and configuration
The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

Quotes from Members

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

Pros

"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"This solution has screens that are easy to understand and provide a wealth of information."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"The network monitoring and configuration within this solution is very good."
"The support from Pandora FMS is legendary."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"Security Onion is the most mature solution in the market."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."

Cons

"I think some improvements to the Android app would be good."
"Pandora could deliver better analytics out of the box."
"It would be helpful to include the generation of reports for times that the network was out of service."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"Their support is good, but it is just online communication. It would be great to be able to just call someone and talk to them instead of always writing. It works well for me because I am a decent communicator in email, but some people might find it difficult to describe in a written fashion and communicate with them that way. There is a learning curve to the interface, but once you get used to it, it is actually very powerful. They have a lot of options, but people struggle with the interface. They've improved it though, and it is getting better. They need to keep improving the learning curve to help buy-in. I'm the guy that manages it, so I'm comfortable with it. They can refine the upgrade agents to be easier. They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way. It has a complete GUI and everything."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"This solution requires proper training to get 100% out of it."
"Security Onion's user interface could be improved."
"The initial setup of the solution is a little bit difficult."
"For Security Onion, setting up and configuring the system can be quite challenging for newcomers due to the need for a grasp of networking and security concepts."
"The product is not easy to learn."

"Pandora FMS is easy to implement and the pricing of licenses is competitive."

"You get the license and it includes updates, new versions, and access to the complete library of modules."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
