Juniper SRX vs. Zscaler Internet Access

Juniper vSRX is an excellent edge gateway device. The combination of Tunneling protocols supported and the advanced routing & security features makes it perfect for this kind of deployment. It is available in physical, virtual appliances as well as support on multiple clouds so you can have the same box be your edge gateway in multiple environments for consistency.

It can also work as a Internet Gateway, DMZ Firewall/Router and it would function just fine.

While it can also work as a DC firewall (North-South), the poor GUI will make it harder in the day to day administration for the multiple policies in a DC.

Zscaler Internet Access has extremely powerful category selection and it is very easy to create your own destinations for inspection and policy exceptions (SSL exception specifically). It is also very affordable and just as powerful (if not more) than some of the other solutions I have used in the past to achieve internet security.

• The Juniper SRX platform is easy to set up (out of the box).
• The support team responds to tickets quickly and with good solutions.

Incentivized

• The depth that Cloud App control policies can go into. Being able to control individual actions within an application, more than just all or nothing access.
• The UX/UI design makes it really easy to navigate the portal.
• Understanding how cloud app/url control policy gets evaluated and creating/editing existing policy is extremely straightforward.

Incentivized

• Some of the more complex setups (clustered HA, etc.) can be a little difficult to configure.
• The lowest-end model that supports true multi-site HA is relatively expensive. It would be nice to have that option in lower models.
• Some configuration options (particularly the way address book entries are done) can get tedious and make for very long configs.

Incentivized

• Easier interface on the menus so they don't disappear.
• Help, I'm contacting support only through the ZIA portal, but I'm unable to use the link easily.
• Mobile interface changes.
• The searching function for the logs is tricky and challenging to use, and the menu always pops down when trying to find the proper function.

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.

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.

There are often performance issues reported

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

Equipment prices ran about the same. Performance and management were also more or less equal. The biggest deciding factors for going with Juniper were (1) fewer security incidents related to SRX firewalls and (2) technical support costs were significantly less.

Zscaler Internet Access is most akin to ZPA - we bought both at the same time to handle all traffic internally and externally. In terms of quality - I would make the statement that Zscaler Internet Access is a simpler product but that's also cause there are no App Connectors involved in that process.

• 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.

Incentivized

• Has allowed us to remove other products that were suboptimal
• Saved us money overall by stacking it with other Zscaler products
• Created a more secure work environment for our users through intelligent internet policies that are not needlessly restrictive while still maintaining security best practices
