Featured Reviews

Sulesh PK - PeerSpot reviewer
Monitoring and Operations Pilot at Egis S.A.
Experience enhanced monitoring with real-time alerts and efficient support
I would like to see automation in the poller features, as currently, the poller is not automated. If we could automate the addition or removal of hosts in the poller, it would improve efficiency. Sometimes, Centreon does not show the status of services as updated, which should be addressed. Additionally, enhancements are needed in identifying configuration issues, providing real-time alerts in case of issues, and improving the HTTP configuration tasks, as Centreon does not currently display issues with HTTP links, requiring manual investigation.
Sai Aditya Panda - PeerSpot reviewer
Student at a consultancy with 11-50 employees
Penetration testing has become efficient as I identify open ports and security risks with confidence
Nmap could potentially become a GUI and provide automatic reports with one-click downloads. For example, the report could show all the open ports for an IP address with a professionally formatted report. This is a far-fetched suggestion and not really required, but it could make the work a little better. On a scale of one to ten, I give Nmap a solid nine. I mean, how can you fix something that is not broken? Nmap is already the best, and I do not think there are any other features that can be added. Its job is reconnaissance, so I do not think there is more to add to it. However, if I get any ideas, I will let them know about this.

Quotes from Members

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

Pros

"E-mail alert notifications are valuable."
"The most valuable feature is that we can manually configure everything we need; because the interface is quite user-friendly, you can configure the system very deeply, which is very pleasant and useful since you can monitor and see everything on your service list, dashboard, or MAP, and you can even create your own plugin and monitoring query."
"The single-pane view provides us a view of all of our network infrastructure, and it is one of the most important tools that we use to see the status of our customers' networks."
"We have a single GUI where we can view the status of all our infrastructure."
"Centreon provides timesaving and costsaving benefits as it lets us manage multiple devices on a single platform."
"For servers and for applications, it was very, very efficient."
"In addition, the flexibility, customizability, and analytics of Centreon's dashboards are all very good. The dashboards help us see the whole network map, and that is quite valuable for us. In addition, the dashboards have helped to improve our visibility and ability to proactively ensure the right data is available at the right time... The flexibility has given us the ability to add in our own monitoring metrics and that has been quite interesting and very useful for us."
"We and our customers have saved so much time that we are acting instead of reacting to a situation in a positive way."
"It is a very user-friendly product."
"This was my first project, and Nmap was the best tool that I have used to date, and I recommend it to everyone."
"The real-time reporting feature of Nmap is particularly valuable. It generates detailed reports on the source and destination IP addresses, the protocols used, and the types of traffic."
"The solution really is not comparable to other products because of its many features."
"The initial setup was simple."
"Nmap is free and should stay this way."
"From a functionality standpoint, it's robust and straightforward to comprehend."
"The most important function, according to me, is the capability to use some arguments in the scanning. The solution's capability to go figure and do a deep dive, discovering information on specific aspects."
 

Cons

"The problem with the reporting is that you have to configure the report, and after that, you will have the same report every month, every week, and every day."
"Centreon supports officially 10,000 services per poller. That is not much for larger customers, because this limit is reached very quickly. We use it with three times the limit without any problems, but Centreon says, "Okay, we are only supporting it with 10,000 services." We are aware that increasing the limit has different impacts because they need to support it. However, for most customers, it would be be very good if they could increase the limit of services."
"There are improvements that they need to make to their API. When we're using different systems and we want to disable monitoring for a specific server, we still can't do that through the API. That's something that's lacking."
"Centreon is actually missing an easy way to create a trendline for the metrics. Actually it is possible to create it, but you need a good knowledge of math, Centreon, and RRD."
"During the initial setup we faced some issues. Part of it was because we had to become more knowledgeable in the solution. There are some gray areas and if you don't know the product well you may have issues. Another part of it was some bugs that we came across, although that's part of every software solution in IT nowadays. But the initial setup could be easier."
"Centreon technical support is only available during Central European business hours. When it comes to critical business solutions, there should be a 24/7 hotline that customers can rely on."
"This solution lacks service monitoring in the cloud."
"They only sell four hour slots for support, so if you have just one question, then you need to pay for four hours."
"There are concerns with the stability of the product, making it an area where improvements are required."
"I would like something more user-friendly to use and export data to various software."
"The price is high and could be cheaper."
"There is room for improvement in the design, the GUI. It looks a bit odd. Maybe Nmap should improve it or add more widgets to make it more attractive, but the basic functionality is good and provides what we need."
"The challenge often lies in finding suitable courses and professional resources."
"The tool's license limits the number of scans it can perform. Improving the license model could benefit customers by allowing more scans for compliance and other purposes."
"Since I started using Nmap, it has been completely based on the command prompt and I think it would help other users if they implemented a decent GUI as well."
"It takes a bit of time to get familiar with the solution and its options."
 

Pricing and Cost Advice

"If you need basic monitoring without dashboards, just monitoring, the plugins are very useful and really cheap. If you want a more complete solution with dashboards and reporting, the EMS solution is great and it is not that much more expensive. It's a good value. Really good."
"The tool is cheaply priced."
"It's quite expensive when you use the Enterprise version, but if you compare it to other providers, it's more like a middle-of-the-line product. It's always good to have a price that is lower, but I would say the price is okay because we get very good support and if we have any other issues we can always contact them. There has never been a time when I didn't get help from them."
"The price is not too high. Licensing is driven by how many hosts you monitor, but because you can run the agentless version, you don't have to declare every host to Centreon, one at a time. That means you can drive your infrastructure supervision with a very low number of declared hosts."
"Centreon is an open source product. Thus, there is no need for licensing."
"For more complex tasks, we use prepaid support days and ask Centreon to come onsite."
"The solution has a free part and after that threshold, you will need to pay. For example, if you believe you can create an interesting map, most of the time, you will have to pay 10,000 Euros per year for having access to these components."
"Centreon is better than Nagios XI in regards to cost and support response times, when you have a problem. If you have a problem, it costs money to contact the Nagios XI support."
"The product's pricing is fine. The licensing options for Nmap include perpetual licenses and volume-based licenses. For perpetual licenses, once you purchase it, there's no need to invest in renewals. And for volume-based licenses, enterprise companies can use it multiple times based on the number of users or devices they need to scan. It's a pay-as-you-go model, similar to how you pay for what you use."
"The solution is free of cost, but there are specific services that we have to buy."
"Nmap is open source software, which suits us well because we are a manufacturing company and not an IT company, for example. If we were an IT company, we would probably need to pay for extra support or instead go for another software solution. But as it is, we don't have any need for high-end troubleshooting tools."
"The solution is free of cost."
"I am using the standard free version of Nmap."
"It's an open-source solution. Commerically, only the support service is available."
"I am using the free version of Nmap."
"Nmap is an open-source product. You don't need a license to install it."
