ExtraHop Reveal(x) vs. Nmap

ExtraHop is a must have for on-premise environments where traffic passes through a physical data centre or network operations centre giving complete visibility into what is happening on the corporate network. This works flawlessly if business operations are in office. For hybrid or remote setups, the solution still works well by placing ExtraHop traffic between the VPN termination and firewall and setting up a span port. ExtraHop works well for cloud based deployments as well with their virtual appliances; however, it does not have the same edge against competition as many CNAPP solutions can gather similar data using graph API's provided by the cloud service provider. That said, ExtraHop does provide some unique features that CNAPP's do not around network operations.

If you're a sysadmin, or anyone who's had to deploy network services, you've almost certainly had to use Nmap at some point or other. Need to see what devices are on your LAN? Nmap can tell you that. Want to check which ports your web server has open to the internet? Nmap is your friend.

Nmap is a powerful command-line tool and has many options that require some reading of documentation to get the best out of (although generally straightforward). If the thought of working at the command-line scares you (presumably not if you're reading this review), then you may want a much simpler tool, or at least check out Zenmap GUI.

• NMap provides a very fast and a very thorough network "sweep" that allows you to quickly map out exactly what's on your network.
• NMap is highly configurable. The "canned" choices are very good in most instances, but using various switches and options, you can create a very specific scan and get exactly the results you're looking for.
• NMap is easy to use. Even a new administrator will be able to use the graphical version (Zenmap) with efficiency right away.

• The GUI version on Nmap could use some improvement with the options that are available to do scans. For example, they could make it easier to select options for the different types of scanning for people who are beginners
• There are no abilities to schedule a scan in the Nmap tool.
• An intensive scan sometimes takes too much time to complete.

Console is easy to use use and familiarize oneself with. Some points deducted as it can be annoying at times to have to drill down using the drop down menu, and then selecting tabs to get the data you want.

Nmap uses are very practical and I don't think there is a better tools for what Nmap does. It is open-sources that therefore there is no cost to use it. It offers a number of benefits, including but not limited to network mapping, port scanning and more. It is very reliable as a network scanning tool.

There is a very large support community and a robust selection of add-ons and scripts. Once you get the use down this is one of the most powerful tools and you can find anything you are looking for as far as examples on the web. While not having official support its not lacking by any means.

I evaluated ExtraHop against Dark Trace. Against all criteria, ExtraHop had a clear edge including visibility, price, effectiveness, integrations, and more.

Alternatives to Nmap (other IP scanners) are often much more limited in what they can do; They often only allow you to scan a specific subset of ports or a limited number of IP addresses in one command. Nmap is unrestricted in that regard. What makes Nmap stand out above the rest, is the complete network analysis package you get with it. It allows IP scanner, network deep-dives, hardware analysis, vulnerability analysis, encryption detailing, and so much more, in one free application

• Nmap with Wireshark is free, so it's been a great combo team to gather info and test.
• It's allowed us to avoid fines from false positives and to fix actual issues ourselves.
• Great for finding hosts, helps keep the network secure.
