F5 BIG-IP Advanced Firewall Manager (AFM) vs. Zscaler Internet Access

We were able to eliminate a firewall from our network architecture by integrating the module into our existing F5 BIG-IP Advanced Firewall Manager (AFM). This allowed us to save on tech refresh costs, since the F5 was able to handle the module without much additional strain on the device. However, if a firewall had features that the AFM lacked, then using that firewall in tandem with an F5 would be preferable.

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.

• 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

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.
