Improves network monitoring and offers insights into traffic, including VPNs
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. This feature is crucial for law enforcement agencies to monitor and analyze network connectivity effectively. It also has traffic analysis. For example, assessing bandwidth usage and configuring the tool to track specific types of traffic is crucial. Unlike SolarWinds, which requires configuration for this, Nmap has built-in functionality that allows it to check all 4,000 computer ports. It identifies the type of traffic each port is using and can easily generate reports on network communications between computers, whether there are 100 or 1000 in the network.

Real-time dashboards have improved our deployment monitoring and incident response
We are using Opsview ourselves, rather than being a consultant or a reseller. We do not use its auto-discovery feature. We do not utilize its API driven architecture. I do not know what metrics we use to assess the effectiveness of Opsview's hybrid IT monitoring. Overall, I am pretty satisfied with Opsview as it is good for what it does. I do not know if Grafana has any other advantages besides better stats, as I am not involved in that side. Based on my experience, I would still recommend Opsview to others as it is good for what it does. I gave this review a rating of 8.

Quotes from Members

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

Pros

"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 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 scanning procedure includes UDP ports which sets it apart from competitors."
"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."
"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."
"The initial setup was simple."
"Nmap has a powerful command line tool and a set of diagnostic features."
"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."
"Overall, I am pretty satisfied with Opsview as it is good for what it does."
"What was very compelling about OpsView was that we could dial out the noise and have meaningful and actionable alerts."
 

Cons

"One of the drawbacks of the standard Nmap utility is that it does not come with a graphical user interface, unlike a number of other open-source alternatives such as Zenmap."
"Customization is not very user-friendly in Nmap."
"Nmap major operates through the CLI; there's no GUI component, and that's where the challenge is."
"The price is high and could be cheaper."
"The solution is not that easy for a beginner to learn."
"Nmap needs to improve its scanning speed."
"They should deliver Playtech's username and password."
"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."
"Customized reporting can be improved."
"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."
"There is always room for improvement, and part of the reason we're looking at Grafana is because there are things it can do that Opsview cannot do as well."
"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."
 

Pricing and Cost Advice

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