Executive SummaryUpdated on Oct 10, 2024

ManageEngine OpManager and Nmap compete in the network monitoring and management category. OpManager seems to have the upper hand in terms of automation, alerting, and comprehensive reporting features, making it suitable for larger environments, while Nmap is favored for its cost-effectiveness in network discovery and security audits.

Features:OpManager provides features like automation, alerting, and a comprehensive view across network devices. It facilitates defining thresholds and alarms, offers excellent server visibility, and enables proactive management. Nmap provides robust scanning capabilities, helping identify services and open ports, and has a powerful command-line interface.

Room for Improvement:OpManager could improve change control, upgrade stability, and backup solutions, while enhancements in dashboard customization and AI capabilities are also suggested. Nmap could benefit from a graphical interface, faster scanning speeds, and a more user-friendly GUI to enhance accessibility.

Ease of Deployment and Customer Service:OpManager is primarily deployed on-premises with a simple setup process but may have limited 24/7 support in certain areas. Nmap offers hybrid cloud options, receiving positive customer service reviews despite being open-source.

Pricing and ROI:OpManager's pricing can be high depending on deployment scale but offers justifiable ROI with reduced operational costs through real-time alerting. Nmap, being free and open-source, is cost-effective, providing significant value for smaller teams focused on security audits without additional support costs.

Reporting features improve operational efficiency while weekend support needs enhancement

Support is moderate and needs improvement, especially during weekends when technicians perform upgrades. During weekends, they need to provide more support to ensure a smooth transition. There is a call for ManageEngine OpManager to scale better in automation and AI functionality. Although the product stability is good, support enhancement is necessary to enable better planning for upgrades and maintenance activities.

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.

More ManageEngine OpManager pros

"The solution detects the operating systems, which makes testing the software much easier before making the payload."

"It is a very user-friendly product."

"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."

"It enables us to delve deeper and identify the services and open ports on the system and visualize this information on a dashboard automatically."

Cons

"OpManager is slow but that just might be the server we have it on. I don't think that's the problem but I don't do the server. But it is slow. When you're interacting with it, it could be more nimble and could be faster."

"It is sometimes difficult to manage the user interface. It can get very complicated."

"They should add more features to URL monitoring."

"Some of our customers have been asking that OpManager have a feature to monitor the operating system, however, I tell them that Endpoint Central is doing that. You can buy endpoints and then OpManager, and they integrate between them, and everything is okay."

"For the implementation part, I am facing issues when configuring the business view."

"Support is moderate and needs improvement, especially during weekends when technicians perform upgrades."

"What I'd like ManageEngine OpManager to improve on is artificial intelligence. In particular, the machine learning feature should be integrated with the sensor flow. Doing this will give leverage, especially when you look at other products such as the Cisco DNA Center. When a switch goes down, I should be able to build on the correlation of other physical devices it's connected to so that I can integrate that with my CA CMDB. The ManageEngine OpManager team needs to draw a long-term roadmap where that feature becomes an integral part of the solution because right now, machine learning in ManageEngine OpManager is a long process. The solution doesn't have MLS search and I want to see ML being developed and applied for CA CMDB to greatly reduce the burden of tying everything. For example, if I have a data center switch that goes down now, I should know what server it's connected to, and when that switch goes down at twenty-four ports, I would get twenty-four alerts for different devices plugged in. I should be able to make a correlation that the major problem lies in the switch and not with the twenty-four elements connected to that switch. That is where machine learning should come into play and the ManageEngine OpManager AI should indicate "This is where the root of your problem is." It could be difficult, but this is a feature that should be improved or added to the solution."

"For the implementation part, I am facing issues when configuring the business view. When I create the business view, I experience problems with the port interface."

More ManageEngine OpManager cons

"The solution is not that easy for a beginner to learn."

"The challenge often lies in finding suitable courses and professional resources."

"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."

"There could be a specific option to check non-pingable endpoints for the product."

"They should deliver Playtech's username and password."

"Nmap needs to improve its scanning speed."

"The price is high and could be cheaper."

"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."

Pricing and Cost Advice

"Pricing for ManageEngine OpManager depends on the number of nodes you onboard and whatever pricing is reflected on the ManageEngine portal which offers discounts from ten percent to fifteen percent. It purely depends on the sales volume and the negotiation. In my organization, there are about one thousand two hundred nodes which cost around $29,000 per year. There's no additional support fee or maintenance fee from ManageEngine OpManager. Pricing for the solution is highly competitive and I would rate it five out of five. ManageEngine OpManager is one of the most competitive options out there."

"The licensing costs depend on the number of devices and accounts that are being monitored by the solution."

"The price of ManageEngine OpManager is reasonable. We have an annual license and the cost comes from how many devices are being monitored. There is not anything extra cost for maintenance and support."

"It is reasonably priced."

"The pricing is moderate."

"The solution is highly affordable"

"We have a standard license for ManageEngine OpManager. We purchased the license for one year and now we are upgrading it soon."

"The initial cost is low and the add-ons are reasonable."

More ManageEngine OpManager pricing and cost advice

"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 open source so it is free."

"Nmap is an open-source and free product."

"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."

"It's an open-source solution. Commerically, only the support service is available."

"I am using the standard free version of Nmap."

"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."

Overview

ManageEngine OpManager is a network, server, and virtualization monitoring software that helps SMEs, large enterprises and service providers manage their data centers and IT infrastructure efficiently and cost effectively. Automated workflows, intelligent alerting engines, configurable discovery rules, and extendable templates enable IT teams to setup a 24x7 monitoring system within hours of installation.

ManageEngine

Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).
