Juniper SRX Series Firewalls vs. Zscaler Internet Access

SRXs seem to be well suited at the enterprise level for plain routers, firewalls, and IDP/IDS. They work well on MPLS and Ethernet, including Internet. I have 3 SRXs also performing edge duty, with 2 in a high availability (HA) cluster. The Juniper line of SRXs provides a good range of scaling from small business to extremely large enterprise. Wire speed is a common comparison factor and Juniper shines in that area.

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.

• 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.

• My only real criticism of the product is that it's hard to figure out how to upgrade the firmware from the CLI via TFTP via the docs, but it works great once you get it sorted.

• 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).

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.

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.

This is the one area where I have a beef with Juniper. When I called into Cisco TAC, 90% of the time, the first person I spoke with was able to resolve my issue. With Juniper TAC, 90% of the time, the first person I speak with is not able to resolve my issue, seems to almost be reading from a script, and must escalate my ticket. All of which takes time.

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

Juniper SRX stands tall compared to all these products for Large Service Provider Networks, where traffic volume is larger. Also, cost comparison with SRX's few other products can also be another contributing factor while selecting this. As well as Juniper Routers, Switches, and multiple products from the same vendor to maintain one single vendor environment. As well as Juniper Support is also really good.

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.

• It is a workhorse for our field operations. It provides the last touch for an ISP to the customer. The customer has no view of the device, but with the repeatability of the device, they do not need to.
• The ability to roll out a dynamic routing protocol attached to a security zone allows elasticity to the environment that supports growth.
• VLAN support on the inside interfaces allow this to be the only device in some smaller deployments we install these in.

• 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.
