Featured Reviews

Harrison Bulley - PeerSpot reviewer
A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built.
AntoSebastin - PeerSpot reviewer
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

"Macros and the ability to connect it to Google Maps are valuable features."
"The apply rules feature saves a lot of time."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"An affordable solution for small organizations to do basic network monitoring."
"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 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."
"The most valuable feature of the solution for security audits stems from the fact that it serves as a powerful tool with the ability to scan a large number of ports."
"The tool's most valuable feature is its scripts. These scripts prove beneficial when security features may obscure or block connections. Nmap helps identify vulnerabilities across different systems, including web servers and various server types."
"The initial setup was simple."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"It is a very user-friendly product."
"It helps us secure the network infrastructure."
 

Cons

"The installation and configuration are very complex."
"The solution lacks many features important to higher-level IT management and network support."
"We have found some problems with Nagios, and support isn't very responsive."
"Icinga’s automation could be improved."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"Customization is not very user-friendly in Nmap."
"The price is high and could be cheaper."
"The challenge often lies in finding suitable courses and professional resources."
"They should deliver Playtech's username and password."
"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 solution's initial setup could be better."
"There could be a specific option to check non-pingable endpoints for the product."
"It takes a bit of time to get familiar with the solution and its options."
 

Pricing and Cost Advice

"We're using the free version of Icinga."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"The solution is cheap."
"It's an open-source solution."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"The product is inexpensive compared to other DBM products."
"The solution is free to use."
"This is an open-source solution with paid support."
"The solution is open source so it is free."
"The solution is free of cost."
"I am using the standard free version of Nmap."
"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."
"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."
"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."
"It's an open-source solution. Commerically, only the support service is available."
"Nmap is an open-source product. You don't need a license to install it."
