    The ACI solution is perfectly fit for a large or multi-site data center environment. It permits simplifying deployment, management, automation, and security. ACI is especially valuable when strong scalability, automation, security, and segmentation are required. However, ACI is less suitable for a small environment due to its complexity and high cost.

    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
    Cisco
    • Cisco ACI, The object model is very complicated. It's something difficult to understand and also because there is a user interface, there's a web user interface, but it's not optimal to use it because if you want to deploy a large amount of VLAN or a large amount of tenants, it's quite difficult to do it or it's quite challenging. Maybe if you want to configure a large amount of ports using the web interface, it's not appropriate because it takes a lot of time. It also provides APIs to do that, but as I say, the object model is very difficult to understand and there is very little documentation about automation of the ACI and maybe there is but it's not so easy to find.

    • 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
    Cisco
    • I think something I've just went to a session with hyper fabric and the ideas that hyper fabric has. Keep it really simple because Cisco ACI is a complex system and adopt some of the ideas behind hyper fabric, bring it to ACI that will be really beneficial. So as I said, automation is a great thing, but it's still, you need to have the background and the really complex stuff that happens behind the scenes to leverage the value of that solution. And by adding more simplicity to it, I think that will be a great thing. And also integrating with other applications in terms of the automation.

    • 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).

    Provided with the intensive fault isolation for the CISCO ACI, we are glad that we have this Data Center Solution in place and we will continue to renew as long as the future needed requirements are meet and more helpful features will be enabled in the future with the integration of security

    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.

    Usability
    Cisco
    You'll need a lot of training and hands on experience to get the most out of the product. There are a lot of very useful features in the ACI product. Often times there are a lot of ways to get to a solution for chalanges in the field. The solutions might be different eacht time. Knowing which one to implement is somtimes a challenge.

    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.

    Reliability and Availability
    Cisco
    It allways works. If there are problems with links going down by accident (say someone accidentally unpatches something they shouldn't have), we rarely miss more then one packet over the link. Also, using VPCs we are able to upgrade the software on the switches without the attached EPs ever noticing.

    Performance
    Cisco
    Day to day operations on Cisco ACI do not require much human intervention, the platform ticks over without any major faults. Being able to rapidly replicate the communication between two groups of machines across multiple sub networks speeds up new application delivery, and the integration into vmWare allows multiple teams within IT to work together to problem solve rapidly.

    Cisco provides users and partners with a multitude of data for you to consume. I think that the stuff in the public domain goes a long way to assisting you find any answers you may need, plus insights and information from areas such as DevNet provide you with access to more than just the traditional release notes and the like

    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

    Actually we start our learning in networking career with Cisco. So it is very useful or easier to learn this product. And honestly speaking, I didn't work in any other data center solution other than Cisco. So I cannot compare what it gives us more than other popular stuff. But this is very nice product like from Cisco.

    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.

    Scalability
    Cisco
    Cisco ACI scales well and is suited in scenarios such as multi-cloud or large data centre implementations. It is not suited to smaller deployments as the efficiencies that it provides are not fully realised. It is well suited in large environments that contain both virtual and bare-metal machines allowing a great deal of flexibility. It is also perfect to support multi-tenancy platforms.

    Return on Investment
    Cisco
    • We've definitely spent quite a bit of time relearning how to do things in ACI, but I think the investment has been well worth while considering that we can now deploy tenants and leaves from the ground up in a matter of seconds.
    • We can if we choose to upgrade an entire datacenters worth of switches in a single night. (We've chosen to break it up for availability requirements, but if you didn't require 99.999% uptime like us you may be able to do it)

    • 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.
