CEO at a tech services company with 11-50 employees
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.

Pros

"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."
"Nmap has a powerful command line tool and a set of diagnostic features."
"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 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."
"From a functionality standpoint, it's robust and straightforward to comprehend."
"Nmap is easy to use. It's a command-line interface, and the output is quite good."
"The scanning procedure includes UDP ports which sets it apart from competitors."
"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."
"I am satisfied with the overall product since it works well…It is a stable solution."
"What was very compelling about OpsView was that we could dial out the noise and have meaningful and actionable alerts."
"It's a good solution. It covers all aspects of monitoring purposes."
"Overall, I am pretty satisfied with Opsview as it is good for what it does."
"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."
"The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup."
 

Cons

"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."
"The solution's initial setup could be better."
"They should deliver Playtech's username and password."
"The solution should increase the number of features under a free license."
"Nmap needs to improve its scanning speed."
"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."
"Pricing and a few certain aspects in the solution needs to 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."
"Customized reporting can be improved."
"Some of the graphics on Opsview could 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."
"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."
 

Pricing and Cost Advice

"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, but there are specific services that we have to buy."
"I am using the free version of Nmap."
"The solution is free of cost."
"It's an open-source solution. Commerically, only the support service is available."
"Nmap is an open-source and free product."
"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 product. You don't need a license to install it."
"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."
