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.

A highly stable solution that can be used to monitor system availability
The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup. You can clone that service, and it allows you to add new services quickly. You can bring up new servers, and you can easily add them. Also, there's an API to be able to add services as well. We don't use the API. We mostly use the cloning function because it stores everything in a back-end database. The underlying monitoring platform for our version is Nagios. That's where we upgraded from Nagios to Opsview.

Quotes from Members

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

Pros

"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"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."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"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."
"From a functionality standpoint, it's robust and straightforward to comprehend."
"The initial setup was simple."
"Nmap has a powerful command line tool and a set of diagnostic features."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"What was very compelling about OpsView was that we could dial out the noise and have meaningful and actionable alerts."
"We use this solution for internal monitoring our own cloud platform because we are a public cloud provider. We also use it for monitoring purposes on behalf of our clients."
"It's a good solution. It covers all aspects of monitoring purposes."
"I am satisfied with the overall product since it works well…It is a stable solution."
"The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup."
 

Cons

"Customization is not very user-friendly in Nmap."
"The solution's initial setup could be better."
"The price is high and could be cheaper."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"There could be a specific option to check non-pingable endpoints for the product."
"There are concerns with the stability of the product, making it an area where improvements are required."
"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 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."
"Maybe the graphical representation can be improved. It can be enhanced for better visualization. It could be a little better. And the graph center can be improved."
"In a future release, we would like to have Observ for AI. Any AI and intelligence it can add to the monitoring is obviously beneficial. We would also like to have automated callouts."
"Pricing and a few certain aspects in the solution needs to be improved."
"Some of the graphics on Opsview could be improved."
"Customized reporting can be improved."
 

Pricing and Cost Advice

"Nmap is an open-source and free product."
"The solution is open source so it is free."
"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."
"I am using the free version of Nmap."
"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 solution is free of cost."
"It's an open-source solution. Commerically, only the support service is available."
"The solution is free of cost, but there are specific services that we have to buy."
"I would rate pricing a seven out of ten, where ten is the highest price."
"The solution is not cheap. I think that the pricing is a little bit on the high side."
"The solution is priced similarly to other tools offering similar features."
