GFI KerioControl vs. Nmap

IT works very well in the non-profit and small business space when there is a need for remote access or connecting several sites in a point to point VPN, user management and rule creation are very easy. The use of the MyKerio website for remote management also makes it easy to troubleshoot problems and make changes if technical staff are not onsite.

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.

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.

Support is very slow to respond and it takes a long time to convince level 1 techs that you need to be moved up to someone more senior. I believe support is outsourced and they are graded on how few tickets they need to escalate to higher tiers so they will try to figure out a solution even if it is detrimental to the overall support experience.

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.

We found Kerio Control to provide the most features and easiest management of all the solutions we looked at, while cost was not the lowest the value was by far the best when you considered all the factors, costs, and manhours involved in deployment and management.

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

• Statefull inspection and web filtering greatly reduce malware incursions.
• Fact it can run on standard PC hardware greatly reduces cost to implement and makes scaling much less expensive.

• 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.
