Likelihood to Recommend 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.
Read full review Pros: Splunk is very well suited if you have multiple log sources of related data. All of them can be correlated and tasks can be automated based on the requirement. Other than alerts, Splunk can also run a specific script of your choice, based on some defined conditions. Cons: If you have a few logs but a large number of log sources, Splunk can be very expensive.
Read full review Pros 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. Read full review Real-time + Scheduled alerts - i-e you can set up alerts which are actively monitoring your logs Pretty good response time for search results. With our key/value logging, Splunk makes it blazing fast to query the data. Dashboards provide insights into historical data Love how Splunk indexes all of the data and provides keys to search on Read full review Cons 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. Read full review At times some queries can run slowly if indices are not on a portion of the query you use. Setup time initially can be difficult if your logs aren't stored in common locations or in a common way to write the log. Ability to ingest logs from different locations without having to change code to put logs in a certain place (pro and con). Searches can be a bit more difficult to look through if your log isn't pulled in a manner that is easy to read through splunk. Read full review Likelihood to Renew We are using Splunk extensively in our projects and we have recently upgraded to Splunk version 6.0 which is quite efficient and giving expected results. We keep track of updates and new features Splunk introduces periodically and try to introduce those features in our day to day activities for improvement in our reporting system and other tasks.
Read full review Usability 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.
Read full review You can literally throw in a single word into Splunk and it will pull back all instances of that word across all of your logs for the time span you select (provided you have permission to see that data). We have several users who have taken a few of the free courses from Splunk that are able to pull data out of it everyday with little help at all.

Read full review Support Rating 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.
Read full review Splunk maintains a well resourced support system that has been consistent since we purchased the product. They help out in a timely manner and provide expert level information as needed. We typically open cases online and communicate when possible via e-mail and are able to resolve most issues with that method.
Read full review Online Training The online course was simple clear and described the main capabilities of the solution. There is also an initial module that can be done for free so anyone can familiarize themselves with the functionality of this solution. On the other hand, however, there could be more free online courses. Maybe even with a certificate, this would broaden the group of people who are familiar with the platform while increasing familiarity with the solution itself.
Read full review Implementation Rating Smooth without too many major issues.
Read full review Alternatives Considered 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
Read full review I wanted to learn a new language that I can quickly master and implement. Splunk is easy, fun to use and best of all, it can be developed in hours not days or weeks. Splunk is fundamentally a programming language that is minimal but yet powerful enough to collect, analyze and visualize data.
Read full review Scalability Splunk can scale in to the petabyte per day range which of course is awesome
Read full review Return on Investment 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. Read full review Overall very positive. It has provided visibility to what is going on within our network. One drawback is the time it takes to get up to speed with the application, but this is up to the user, and Splunk education is excellent. In my field, IT Security, there are few other friends to have in your back pocket better than Splunk. They are just that good. Read full review ScreenShots
