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.

Quotes from Members

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

Pros

"The solution has all the features that we need, however they do not work correctly."
"Easy to use, scalable, stable, and very intuitive platform that provides protection against security threats."
"The setup is very easy and straightforward."
"Monitoring customer's critical network is now almost a one man job."
"AlienVault provides you with a unified view for all aspects of what is going on in your environment."
"I highly recommend AlienVault USM for anybody that is seeking a SIEM solution that is easy to implement and easy to manage."
"Vulnerability scanning helped out shortcomings of what was not patched in the past and what needed to be patched. This assisted with fine tuning the environment for compliance."
"Here we can get file integrity monitoring and a vulnerability assessment tool together with SIEM."
"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."
"The product is scalable."
"A great feature of the solution involves its internal portal."
"The initial setup of Nagios Log Server was easy and straightforward."
"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."
 

Cons

"Their threat intelligence platform needs to be broadened."
"The web UI can be clunky at times, with poor error handling."
"As this software is in the cloud, you do not have control on updates and general changes which are happening."
"I would not recommend anyone to use it. I rate ATT AlienVault USM a one out of ten."
"The Log Management and configuration of email notifications should be user-friendly."
"Most of the troubleshooting requires going through the Linux command line and bypassing the GUI."
"The biggest improvement they could do is to provide full support for IPv6 addressing."
"Customer service is 4/10 - they need to provide faster responses to emails."
"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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The configurations during initial setup could be improved."
 

Pricing and Cost Advice

"I don't know exactly, but I know it is based on the number of logs and the retention duration, such as 30 days or something like that. So, the smallest package is about 500 a month for 30 days of logs. There is a virtual machine. You need resources for it. It is a log collecting VM. They provide the software, and you just have to load a virtual machine. So, you're going to incur some CPU RAM and storage for wherever this log collecting appliance is running, which typically is in our cloud and on our platform for the customer."
"We checked out several competitors. For what it can do and the cost, it was the best option!"
"The pricing is a good value. The key thing is that for the new product, the licensing of it, is subscription-based and it's based on data. Clients need to be really careful when thinking about that, because odds are they're going to need to put a lot more data into it than what they initially estimate, which is going to drive their subscription costs up."
"They charge a license based on the storage. ATT AlienVault USM is a less expensive solution than IBM QRadar."
"Its price is much lower than McAfee ESM."
"Pricing is very competitive with other products and you get much more functionality from AlienVault."
"​The vulnerability management solution is worse than buying a Nessus Professional license.​"
"So far, it has been a good solution for a tight budget."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"For a single instance, the price is around $4,000."
"We found the pricing to be quite affordable."
