A stable, scalable, and flexible monitoring tool

Real-time data is one of the unique features that ITRS Geneos offers. For example, if there is an impact on a particular server and a particular application, I want to see what the impact is or what the CPU or hardware usage information is, as well as the service in the same application. I can see the real-time data and the impact by accessing ITRS Geneos and looking at the tree. I don't want a tool that tells me when something is broken. I want the tool to tell me when something is going to break. That is the difference between ITRS Geneos and other tools. I want proactive monitoring, not reactive. I don't need to be notified after the fact that something has broken. If something is broken, I get a notification by email, and some of my customers are going to call me. ITRS Geneos provides proactive monitoring. The great advantage of this tool is real-time monitoring. ITRS Geneos not only alerts us but also gives us a real-time view of the data. This is the tool's first great advantage. It is also lightweight and flexible and can adapt to monitor even low-latency systems, which is the tool's second advantage. Another great feature of this tool is its good presentation layer, which allows us to build custom dashboards to present to business stakeholders. This gives them a high-level status of what is being monitored. If we compare ITRS Geneos to other tools, we will find that each one specializes in a specific area, but the ITRS Geneos tool is more comprehensive. This is its great advantage.

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.

Quotes from Members

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

Pros

"The ability to build integrations to tools that are not monitored out of the box is the most valuable feature."

"It's also easy to implement. The implementation of Geneos is very easy and interesting. It's not complicated. It's very quick to implement. The installation is very easy. There are many topics about ITRS Geneos that explain more about the features of the function of Geneos."

"This solution has helped provide relief to existing Level 2 teams, allowing them to focus efforts on in-depth problem analysis."

"Real-time log monitoring with desktop alerts is valuable as it tells us immediately when there is an issue."

"It's a very powerful application monitoring tool across the industry. Many free, open-source tools are available. There are also paid tools, but ITRS Geneos is a real-time application monitoring tool where the user can monitor, self-configure, and manage alerts through their console."

"One of the most valuable features is that it can be configured by non-developers. It doesn't require development expertise to configure it."

"One of the best aspects of Geneos is that it has a broad scope and can cover a lot of use cases. You can write your own scripts to monitor really specific things. And the rules that you can put in place can be quite complex for the alerts."

"I would say that it is an easy-to-use monitoring tool. Amongst the available monitoring tools, it is a really good option."

More ITRS Geneos pros

"It is a very user-friendly product."

"Nmap has a powerful command line tool and a set of diagnostic features."

"It helps us secure the network infrastructure."

"From a functionality standpoint, it's robust and straightforward to comprehend."

"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 scanning procedure includes UDP ports which sets it apart from competitors."

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

"The initial setup was simple."

More Nmap pros

Cons

"There is one drawback to using lightweight data collection: we lack the feature of observability based on time series, such as historical model data. This makes it difficult to view data in ITRS. ITRS needs to improve this feature."

"ITRS have started to make some major changes that we haven't taken on board yet, in the creation of dashboards and more visibility of the metrics that we collect. At the moment, that's something that's lacking, but I know they have addressed it. Still, it’s not that easy to create stuff to help with visibility and dashboarding in Geneos."

"The ITA, the post-incident analytics, could be improved."

"At the moment Geneos is excellent and handling real time monitoring, however not great at doing historical reporting."

"I would also like to see suggested guidelines to accomplish a monitoring task. The issue is that ITRS is so flexible that there is more than one way to complete a task, each with benefits and disadvantages."

"A lightweight version which could host more than 100 gateways, as we can see slowness while loading all our gateways."

"One area where there is room for improvement is the log file. I would like to be able to do a pre-run on the log files. When you are testing log files for regular expressions, it would be good to be able to do a quick check up front on that side of things before you release that into production."

"Their cloud monitoring solution needs to be improved. I have already given them the feedback that it's not capable of meeting the latest technology needs."

More ITRS Geneos cons

"Nmap needs to improve its scanning speed."

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

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

"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."

"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."

"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."

"The price is high and could be cheaper."

More Nmap cons

Pricing and Cost Advice

"The organization is not just purchasing a license for the product, but also managing services and professional services from ITRS. Another factor is if the implementation is going to be in production, non-production, or both."

"Pricing is the touchy subject, even here. Upper management always wants us to find a cheaper solution. But we have so much integrated with ITRS... It's expensive, but it does its job very well. And you set it and go."

"I can say it's not that cheap because the licensing is a little bit costly"

"Its price is reasonable. It isn't too expensive, and it isn't too cheap, but it also depends on a company's volume and negotiation."

"The licensing cost may seem expensive upfront. However, the service is outstanding, the tool does things that no other tools can do, and the customizability more than makes up for the cost of licensing."

"The pricing is fairly market-related. They have been very lenient because we have been working with them for so long. An example is that we're currently migrating some of our services to AWS, and they've given us a grace period for some of the things to help with the migration and not to grow additional costs while we are migrating, but it's still on par with the market."

"It is expensive. They have to look at the model around when we move to cloud and how that's going to work. The licensing cost does pay off because of the improvements in support to our business."

"When I first came in, their pricing was very high. ITRS had a high expectation of what their price should be based on perceived value. I think they have been realizing, more recently, that there are other competitors, so their pricing is a lot better. Licensing for on-premise is okay, however I feel there is quite some work to be done for cloud and containers. We're still working with them to try and work out what that pricing should look like."

More ITRS Geneos 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."

"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."

"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."

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

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

"I am using the free version of Nmap."

ITRS

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).

Sample Customers

ITRS Geneos is used by over 170 financial institutions, including JPMorgan, HSBC, RBS, Deutsche Bank and Goldman Sachs. Clients range from investment banks to exchanges and brokers.
