Nmap

NMap is well suited to just about any situation, network size, or complexity. Some have brought up the point that NMap's proxy settings need work. I haven't used NMap with a proxy. NMap is my "go to" tool for a cursory security sweep. Once a problem is found, I can perform a deeper dive scan on a system or a network. I wouldn't, and don't, use NMap as my only security tool. No single tool has all the answers. For example, it is not a Wireshark in that it does not capture packets or analyze them. It is basically a port scanner, host discovery, OS detection tool.

Sensu

Sooner or later, companies are going to figure out that there's more to monitoring than what Nagios can provide. For those that want to dip their toe in the water and still provide backward compatibility with a legacy Nagios environment, Sensu is a good choice.It's mainly for businesses that want more than Nagios but don't want to take the full plunge with something radically different and metric-based such as Prometheus.Having moved to metric-based monitoring so far as I'm able, I can say with confidence that it's far better than what Nagios or Sensu provide.

Pros

Nmap

  • Nmap has a unique process of fingerprinting applications/devices to help us identify their communications patterns quicker.
  • Nmap can be used for network auditing by specifying whole subnets that you would like to scan for open/closed ports.
  • Nmap has a diverse presence and can be used from most operating systems.

Sensu

  • Unique concept as a "monitoring router" that can tie services together.
  • Backward-compatible with Nagios environments.
  • More of a DevOps focus than Nagios.

Cons

Nmap

  • Maybe take some of the features of Zenmap and bake them in?
  • Include fancy extra graphical results charts or graphs or something to show people who you want to convey info too but have no idea what Nmap is actually doing.
  • I don't really think I'd change a lot actually.

Sensu

  • Terrible documentation that assumes you're already an expert in everything that Sensu can do.
  • Significantly more work than Nagios to get basic checks on and configured.
  • Web interface is primitive and not even on the same level as Nagios XI.
  • Large price hikes after Sensu Go was released.

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.

Sensu's customer support was always willing to work with us but never really seemed to learn much from our experiences. I think they get a lot of customers with DevOps IT teams that are willing to put in a lot of elbow grease to get the most of Sensu's architecture.However, despite explaining my continued disappointment with their documentation and the overall flow of the product, I never got much more than a "sorry" and a notice that their documentation was open source if I wanted to contribute to it.The problem, of course, is that you can't document what you don't understand. I'm a former technical writer, so I know that better than most.

Alternatives Considered

Nmap

NMap usually lacks the features of the other network scanners, but for a good reason: most of the other network scanners out there are using NMap as part of their system. The nature of NMap (being open-source) is that it is available for use in other applications; as a result, these other applications make use of the NMap source code.

Sensu

We initially compared Sensu to Nagios XI. Nagios has languished for years and clearly wouldn't scale well without a lot of effort, while Sensu's architecture was clearly designed to be better at scaling horizontally.

Return on Investment

Nmap

  • Positive return as it's open-source (free) on all OS's.
  • If a person is not used of the command line there are a ton of front ends that make it point-and-click so the learning curve is good. That cuts down on time and manpower.

Sensu

  • Standing up the Sensu Go server took very little effort.
  • Setting up and maintaining the build processes and deployment logic for Sensu assets and checks was somewhat exhausting and resulted in lower adoption among non-DevOps IT.
  • The limited web interface resulted in lower adoption among non-DevOps IT.
