Definitely in larger environments, more mature organizations that obviously have the budget to spend and want best in class. Where it struggles is those organizations that don't have the funding and money to spend on it and need more basic functionality. So I'd say that's smaller customers we've worked with and kind of mid-market. They tend to get scared when they get the quotes. Also we've had some struggles with account team consistency. So for the sales team, just a lot of turnover and a lot of missteps on customer calls.

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
F5
  • I mean from a basic level, it actually satisfies all the use cases we have, which is basically to have multiple web servers for the front end and then you want that to be equally split across. The traffic comes in from all over the world. We use DRA protection and everything, but then we also internally want to make sure all the servers are being utilized and we provide much more availability across all servers. We just make sure BIG-IP sits in between and handles the traffic accordingly. And it's pretty basic and it comes to drawing traffic. It's pretty easy to configure and set it up and then forget.

  • 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
F5
  • Recently we have been deploying F5 web application firewall and we have started the deployment. We have already moved applications out there, but we are not yet to the point wherein I could comment any positive feedback or any negative feedback because we are still going through it, right. But as far as I'm concerned, I don't see any drawbacks or any shortcomings on the F5 product lineup.

  • 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

So far experience with F5 BIG-IP has been good, but we are only 6 months into the deployment and will depend on how things run over time.

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
F5
It's not difficult to understand the parts of application configurations and features. Setting up new virtual servers with multiple profiles, certificates, and nodes is easy for new users through the web interface, which also translates to programability in scripts, DevOps, or other configuration management use-cases. Users from different backgrounds such as networking and infrastructure can use F5 BIG-IP, while users who are familiar with API calls can easily configure objects without needing to understand the platform at all.

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.

Support Rating
F5
On the occasions when we've had to engage f5 support, they have been great. They have always resolved our issues quickly and been easy to work with and professional. The reason I give them a 10 out of 10, however, is because when we've had issues that have crossed over between the f5 BIG-IP, our Cisco switches, and our Microsoft IIS server the f5 support representatives have been extremely knowledgeable about every product and device involved and have been able to troubleshoot end-to-end without having to engage other vendors.

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

That's the one thing that really stood out. It was a lot easier to use from an administrator standpoint, so I think that's the one thing that really made our team decide to go with this product versus another competitor. Just ease of use.
