Simon KONAN - PeerSpot reviewer
Plug-ins are free but it has limitations in sending out information to users
The issue my company has with the tool stems from the fact that it didn't give an on-time response to us. The product collects the information, but it fails to send them via SMS, WhatsApp or Telegram. The solution can be used if you want to get email notifications, which is not good for our company because if someone is not in front of their desktop, you can't receive information about an equipment or LAN that is down.

Scans the network and identifies vulnerabilities on each machine
Nmap is mostly helpful during compliance checks. We run the scanner to see how many devices are on our network and find vulnerabilities in those that aren't compliant. We also use it monthly to scan our network and identify devices that aren't connected properly. This helps us detect any issues related to the operating systems of these devices. The tool's most valuable feature is its vulnerability scanning. It allows us to scan a specific range of IP addresses and discover devices within that range. This makes it easy to identify devices and view their details. Port scanning is crucial for network management tasks. It helps us identify vulnerabilities by finding open ports that may be unused or misconfigured. This tool makes it easy to detect such issues. The OS detection feature is great. Unlike other tools, Nmap provides accurate information about asset vulnerabilities, helping us easily detect and address them. Using Nmap provides value to the company, especially during compliance audits. It helps generate reports on assets, updates on workstations, and insights into network activities and potential attacks. Additionally, Nmap detects vulnerabilities and provides port details, allowing us to close unused ports on the client machines.

Quotes from Members

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

Pros

"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 have a single GUI where we can view the status of all our infrastructure."
"Centreon's most valuable feature is Opsgenie."
"Centreon's most valuable features are preventative maintenance and cost-efficiency. Everything is monitored, and we get a log before the system fails. We have an opportunity to fix the issue and avoid downtime."
"The downtimes feature is helpful. If the ISP is doing some maintenance on its network, we have the option to put downtime on the devices or the services, so we won't get any false alarms."
"We have the business activity monitoring, the map, and the MBI modules and they are all very good."
"I can't point to one valuable feature. All of Centreon is good."
"The most valuable feature of the solution is that most of its plug-ins are free."
"The solution detects the operating systems, which makes testing the software much easier before making the payload."
"Nmap's performance is great, and I've never noticed any issues in this respect. It really doesn't put a heavy load on the machine when using it."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"It is a very user-friendly product."
"The best feature of Nmap is that it lets me see useful information about each endpoint in my entire network environment. For example, I can see every single connection of the network as well as each and every port."
"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."
"It helps us secure the network infrastructure."
 

Cons

"Centreon needs to improve the granularity of the data as well as the graphical data. It would also be better to if there was improvement to the filtering/grouping system as well as the creation of views."
"The problem with the reporting is you have to configure the report, and after that, you will have the same report every month, every week, every day. You have to sync it in order to have a great report."
"I would like to see more plugins. That is something it needs. There is also room for improvement through dynamic thresholds, or self-discover thresholds. I would also like to see a discovery feature that could map the whole network environment and automatically suggest things."
"The Home view could be improved by adding customization functions that allow users to change the size of the widgets for a more uniform layout."
"Centreon is very bad with auto-scanning. It's very monolithic software. It doesn't have microservices and it only has basic clustering. You cannot, for example, have six or seven nodes for Centreon's cloud processes."
"Centreon introduced network discovery in the most recent update. However, it doesn't work well. Our previous monitoring tool could discover networking equipment on the network and identify the relationships between the devices."
"It is necessary to improve service monitoring of database services in the free version."
"Sometimes, Centreon does not show the status of services as updated, which should be addressed."
"It takes a bit of time to get familiar with the solution and its options."
"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."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"There are concerns with the stability of the product, making it an area where improvements are required."
"The challenge often lies in finding suitable courses and professional resources."
"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."
"There could be a specific option to check non-pingable endpoints for the product."
"Customization is not very user-friendly in Nmap."
 

Pricing and Cost Advice

"You purchase a package. You have a support contract (there is also a platinum support contract) and it is per module. That means you have to pay, e.g., for the MBI module or the BAM module. Or, if you want to save a lot of money, you can pay for IMP, which is the complete package."
"Open-source solutions like this can be very cost effective for an organization looking for a product that they can quickly implement, as there is no initial cost and there are no license renewal fees. However, it is important to take into consideration some of the related costs that may come along as needed, such as training, support, and product enhancements."
"I think Centreon's pricing is fair, especially given the criticality of our system. They were cheaper than the other solutions. The licensing terms were pretty straightforward. I believe it was based on the number of hosts."
"It is perfect and very cheap if you are a little company or startup. After that, it is quite expensive for a big company."
"The tool is cheaply priced."
"Their licensing model is really easy. You have one license and you have access to all the features, compared to other tools where you have to purchase add-ons."
"Centreon is an open source product. Thus, there is no need for licensing."
"In terms of licensing, you have to think through if the components that need licensing are really needed. For example, the Map module: If you don't need a map to be shown, I don't see a point in paying for those licenses, if you just use it a couple of times a month or a couple of times a week... You can use the Centreon free version and get the main features. The licensing part is, I would say, only for bigger customers who have the option to pay more and who really need those kinds of modules, fancy reports, etc."
"It's an open-source product, and I haven't seen any premiums. Options are available for those who purchase, but for my use case, everything I need is available in the community and forums."
"Nmap is an open-source and free product."
"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."
"Nmap is an open-source product. You don't need a license to install it."
"I am using the standard free version of Nmap."
"The solution is free of cost."
"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 open source so it is free."
