Nmap vs. Zscaler Private Access

Nmap is the ideal solution if you are working alot in network environments. If you come to grips with the syntax and the most-used features (the online community helps alot), you will be able to much more quickly and thoroughly troubleshoot networks or check for security vulnerabilities, for instance. It is free to use and is available for Windows and Linux, so I would say it is very much warrented for any network administrator or sysadmin to take it out for a spin.

The tool is, for the most part, very intuitive. Most of our issues so far (working through them with our Resident Engineer) are the one-off applications. We are working on some exemptions to make them functional. Besides that, the team loves the tool and how it can provide better security than our previous tool.

• Nmap is very good at discovering systems on your network.
• Nmap is very good at guessing a systems operating system with a high degree of accuracy.
• Nmap is good at validating externally facing systems to make sure that unauthorized access is not allowed.

• Allows strong cyber security corporate policies
• Very reliable VPN application that operates at 100% efficiency
• Very easy to be configured with friendly user interface

• exporting, There's a serious lack of ability to export the information in a readable format to present to VPs and such. I always find myself doing a lot of data massaging to get it in a pretty format
• some scans can trigger sensitive IDS/IPS
• SYN scans can be particularly aggressive and cause problems on remote systems.

• Granularity and Complexity of Policy Enforcement
• Application Segmentation and Listener Configuration - The way applications are defined and listened for is fundamental to ZPA, but can be a source of frustration, especially when dealing with legacy or non-HTTP protocols
• The ZCC is the user's primary gateway, but its control over local system network behavior can sometimes clash with enterprise requirements.

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.

Few things stand out. The ease of access: It very convenient - one click to open add details and done. Packet capture: Can't talk enough about this feature. Troubleshooting private access is always problematic,but this feature helped a lot. One thing that can be improved is early warning about expiring authentication

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.

A similar but more basic alternative is available on Android, called Fing. It's very useful for diagnosing issues on networks when you only have your mobile device to hand.

A graphical user interface alternative to Nmap, is Zenmap. It's the official GUI for Nmap and does use Nmap under the hood. It makes things a bit more 'point and click'.

All of these tools are for different needs. Zscaler Private Access being for internal seems very simple as it really only allows filtering up to L4 whereas ZIA allows for filtering up to L7. ZDX often tries to give insight into the environment but since it only works with preconfigured items, that then means when a new problem shows up - ZDX isn't helpful troubleshooting postmortem. For the internal side of the house - Zscaler Private Access' strength is its simplicity to configure.

• NMap being free of charge has a positive impact on our budget. It is an enterprise-class tool that anyone can download and use.
• NMap, both command line and GUI, is a very advanced tool that is easy to use, so there's very little learning curve involved, which has a positive impact on productivity and security.
• A valuable feature that is a huge time saver is that you can compare scans. This saves hours of searching manually for differences in scan results. Faster results means faster mitigation of problems, which can be a real money saver.

• Positive: We have now charged users internally for the service
• Negative: Dealing with users who also have the Zscaler Client Connector for their company, can cause confusions
• Negative: Enabling the Zscaler Internet Access entitlement has been a major headache for us because Zscaler Private Access users can't autheniticate through ZIA on a non corporate device.
