    I can't think of scenarios where it is less appropriate, unless we are talking about real tiny businesses. More businesses will find Cisco Secure Firewall an outstanding tool to use, love, and trust from a reputable Network giant vendor. It is a must for businesses that want to focus on what they are doing, and leaving the network security for the pros.

    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's firewall actually does its job of blocking what it is supposed to block. We had an old Firewall that led to slippages. Cisco catches 97% of malware and vulnerabilities during testing. For Coitiar, that means an engineer who clicks a link with malware is handled quickly.
    • We actually tested if failovers would affect running sessions. We pulled our primary unit during a certification submission period. The firewall just switched, and the connection kept running.
    • The AI assistant in policy management is excellent, and for our lean team, it makes the whole process easy and efficient. I don't have to audit 200 policies manually; the AI steps in and does its thing.

    • 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 mean I think a lot of the technology with managing them is getting better. There's a few cons to the new firewall management console. You can't sort through routes or I think you can with interfaces now, but there's a few caveats that they haven't really worked out yet, but they're implementing AI into it, so it's getting to be a lot easier to use.

    • 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).

    It works really well. We can do most anything we want or need to with it, and you don’t have to have a doctorate or multiple certs to necessarily figure it out. The thing that would probably have to happen to make us switch would be if we just got priced out - Cisco’s more powerful and higher bandwidth models cost a pretty penny.

    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
    i think overall after ALOT of tac cases it works allright now. But still have alot of issues if you use cloud based mangement. fx, if you open 2 windows of access policys, both of the pages, rules starte to jump form side to side. if you then open one more list, its start to jump even faster. if you close the 2 of them, its back to normal. ALSO the extended access lists for VPN, SUCKS. Its the tiniest window when opening the editor, and you are not able to give the rules names, Which means finding and editing rules SUCKS, its a horrible experience, and eveytime we have to we want to yell :P

    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
    Rationale:


    Strengths:


    High availability (HA) and failover configurations ensure continuous operation during hardware or network issues.


    Minimal unplanned outages reported; system remains responsive under full inspection load.


    Centralized monitoring and proactive alerts help prevent downtime.




    Minor Considerations:


    Occasional maintenance windows or updates may require brief service interruptions.


    Complex integrations with other systems may sometimes require extra attention to maintain uptime.




    Overall, Cisco Secure Firewall is highly available and dependable, supporting business continuity and operational resilience.

    We have not had any performance issues with Cisco Secure Firewall, even with DPI and IPS enabled, we have not seen a performance hit. Emoployes have not complained about any slow network speeds that could have been attributed to the secure firewall it has always been something else within the office network.

    I rarely get the support I need in the time I need it. Often, while they are "looking at packet captures and going to get back to me" I fix the problem on my own. If you were to look at my TAC cases over the past year, you would see some very lengthy cases that usually ended with me contacting the TAC person and telling them to just close the case

    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

    Cisco Secure Firewall works better with the Cisco ecosystem when we can utilize it and feels beefy enough when we utilize it in the data center. The Fortinet we have found are great, small cost boxes for remote offices with a better UI then Cisco Secure Firewalls. The feature set included with the firewalls feels similar from a security point of view.

    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.

    Cisco Secure Firewall has never given us any trouble, it has stayed up at all times, upgrading the appliance has also become much simpler. We operate the appliance in a HA pair, so 0% downtime within our organisation. During switchover while upgrading, not a single packet seems to get lost, so this has been a very valuable asset to our company.

    • 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.
