    NmapZscaler Internet Access
    Likelihood to Recommend
    Open Source
    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.

    I feel the product is very good to set up basic standards and go beyond that in many aspects. However, due to being sometimes too simple, it limits the ability to do some other complex changes. Having the ability to do both would be ideal for some, if not all, of the products within Zscaler Internet Access. A simple setup to have it stand-up, and more advanced settings for those more experienced.

    Pros
    Open Source
    • 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.

    • Provides a secure VPN connection point for endpoint connectivity.
    • Provides the VPN connectivity in a fast and reliable connection state.
    • Very dependable, once connected the connection stays up and there's no fuss.
    • Very good at letting you know when you are not authenticated.
    • Very easy to authenticate and regain access when your session times out.

    Cons
    Open Source
    • 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.

    • ZS CLI support to turn off ZIA and ZDX service specifically on mac.
    • Better visibility into failed posture devices, including a timeline and the reason the posture failed (This is about the Zscaler mobile portal: Enrolled devices --> Failed posture devices).

    While Zscaler Internet Access (ZIA) delivers critical value in cloud security and RBI compliance, I rate renewal likelihood 7/10 due to evolving needs versus platform limitations. Below is my rationale:
    Key Gaps:
    1. Advanced Threat Costs:
    ZIA’s add-ons (e.g., Advanced DLP, Sandboxing) incur 35%+ cost premiums – straining budgets as transaction volumes (UPI/iMobile) grow 50% YoY.
    2. API Banking Scalability:
    ZIA’s API rate limits throttle real-time policy sync during UPI peaks (10K+ TPS), forcing workarounds for finacle integrations.
    3. RBI Future-Proofing:
    Limited native support for upcoming digital rupee (CBDC) security rules requires custom development, increasing compliance overhead.

    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.

    Getting started was pretty straightforward. We can tell the product is way more robust than we are using it. It started as a replacement for previous DNS-blocking content filtering, but we're exploring how this will add value with an upcoming DLP redesign and with traffic optimization at some of our remote sites with severe bandwidth limits.

    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.

    Zscaler's ZIA support is quick and knowledgable. They respond within 1-2 hours of you submitting your ticket. They are very thorough and are typically ready to jump on a live troubleshooting session. Our ZIA platform and how we use is it unique so at times tickets can be open for weeks but we alway get quality support compared to other unrelated product support in our enterprise

    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

    The overall user community and scope of supportability outweighed the others on our short list. Netskope was a close second, but the risk, though small, was greater than that of bringing Zscaler aboard. We were looking for a mature, well-supported, highly functional, and fine-grained solution that met all our user and information security requirements.

    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.

    • I would say it has a very good ROI, as whenever someone can't access something, they submit a ticket to our network engineer, and within minutes, the site is safely added to ZIA with best-practice configurations. After seeing a little of the UI from the Zenith event, it seems very user-friendly to control these policies.
