    It’s a dedicated Network Advanced Threat Detection and
    Prevention solution. Easy maintenance and low operating costs fit perfectly for
    SMEs. Variety of appliance selection makes NX the perfect choice for large
    enterprises. As it’s a dedicated solution with its own appliance, price is higher
    compared to NGTP add on solutions. FireEye is an ecosystem therefore when you’ve
    the EX or HX vice versa, you should be looking to NX. Otherwise, you’re missing
    the threat intel exchange on the network side reverse is the true. Sizing is
    important before the purchase, if you select a low end model for a busy network
    you lose your initial investment. For multiple NX deployments I highly
    recommend CMS. Without CMS you’ll lose the threat intel exchange and this will
    negatively reduce the risk scores.

    It's best suited for a distributed remote workforce, securing internet access for users from anywhere. Suitable for highly regulated industries, such as banking and Healthcare. Not a good fit for an organisation where most of its legacy is in an on-premises environment. Bandwidth-intensive industries like media/entertainment firms.

    Pros
    Trellix (FireEye + McAfee)

    • Inline mitigation capabilities particularly well.
    • Different deployment models for specific needs.
    • License and information sharing selection 1 way or 2 way mode.
    • Frequent updates.
    • Low false positive rates.
    • FireEye sandboxing is immune to sandboxing attacks.
    • Central management (CMS) capabilities for managing several NX's.

    • Upgrades and updates with zero down time.
    • Local FireEye support is superb.
    • Multiple deployment scenarios (span, inline) in the same NX for different interface pairs.
    • SSL inspection support.
    • No need to maintain, build or updates the images. It's highly automatic.

    • Single Pane of Glass Management - Everything is very easy to access and monitor the entire environment from an internet security perspective.
    • Install Flexibility - We can and do install Zscaler Internet Access on both our client devices as well as our SD-WAN appliances and servers. This allows us to control internet security even on devices without an agent in our networks.

    Cons
    Trellix (FireEye + McAfee)
    • Very first detected APT sample can pass the NX even it's inline blocking mode.
    • Performance optimization for busy networks is cumbersome.
    • CMS does not provide all the management capabilities, CLI or local config. Should be done for advanced customization.
    • Constant limitations of tcpdump/ packet capture for 10G interfaces.
    • IPS functionality is a bit cumbersome, not a full feature IPS, lack of signatures and customization of IPS signatures.
    • It's not a full NDR solution or a UBA solution.
    • Lack of device or user mapping.
    • Forensics is based on the specific APT. May not provide the whole story and need some additional tools.
    • You cannot make manual submission to NX (needs AX).
    • You cannot access the kernel directly for deep analy[sis] or troubleshooting (assist from FireEye Support should be taken).

    • The logs feel kind of lack luster
    • When issues are arising with SSL Inspection, logs show everything working despite end user experience
    • Could use some kind of global find functionality or something that would allow you to search the entire configuration for matching URLs and the like

    Zscaler
    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.

    The application is easy to install and configure on all Windows devices. To troubleshoot any internet issue, we can easily collect all the relevant logs from Zscaler and check the exact issue. The only problem is with the uninstall, as a dedicated crew needs to provide the password.

    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

    FireEye NX is a solid product. It gives you sustainable
    security throughout the organization. NX detection engines are more capable
    compared to others. Its catch rate is higher, FP rate is lower, [and] speed is
    awesome. NX can work for highly regulated environments with 1 way solution.
    Operation costs are much lower. Software quality is very good. It may have bugs, but these bugs do not compromise the security in general. SOC team loves the
    FireEye NX for its pinpoint detection capabilities. Local and partner support
    is exceptional.

    Zscaler Intenet Access outperformed the competition due to its lightning-fast policy delivery and cross-compatibility. It is easy to track employee usage and block unnecessary websites, reducing company internet usage. Zscalar installed on every system increases cloud-based software bandwidth, decreasing user turnaround time and increasing efficiency.
