It is well-suited for all sizes of organizations. It will help them to safeguard their network from various cyber threats like ransomware, phishing, malware, etc. It will provide them with many features like deep packet inspection, web filtering, application control, etc. in one place. It will also help them optimize bandwidth usage

Zscaler
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

I rated Sophos SG Firewall a 9 out of 10 because it has consistently provided strong and reliable security for our organization over the past five years. Its unified features like IPS, VPN, web filtering, and reporting make it easy to manage and highly effective in protecting our network. The interface is user-friendly, and support from Sophos has been timely and helpful. I deducted one point only because deeper cloud-native integration and more advanced analytics would further enhance its future readiness.

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
Sophos
Management could use some improvements. Sophos management and workflows has always been designed by Engineers for Engineers. They do not always follow logical workflows in the real world. Once you figure this out it is easier to use but no where as smooth as many other products on the market.

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
Sophos
The biggest selling point for sophos is their vendor support. Those guys put a smile on our faces. There are multiple ways you can contact their support like chat, or telephone or email. They are very responsive and they do have very knowledgable and patient support staff. We have raised tickets at all odd hours and they have been addressed correctly

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

Implementation Rating
Sophos
I was very satisfied with the implementation of the Sophos SG Firewall, giving it a rating of 9. One key insight from the implementation process is that while the setup was relatively straightforward, it’s crucial to carefully plan the network configuration in advance, especially for high availability (HA) and VPN setups. Ensuring compatibility with existing infrastructure and performing thorough testing before going live can significantly reduce issues later on. Additionally, leveraging the built-in wizards and configuration guides helped streamline the process, but hands-on testing was essential to ensure everything worked as expected in our specific environment.

We use Sophos in conjunction with WatchGuard, for an extra added level of security. Sophos is a little more sophisticated and complicated but they work well together as added layers of protection against most cyber threats.

Zscaler Intenet Access outperformed the competition due to its lightning-fast policy delivery and cross-compatibility. It is easy to track employee usage and block unnecessary websites, reducing company internet usage. Zscalar installed on every system increases cloud-based software bandwidth, decreasing user turnaround time and increasing efficiency.

Contract Terms and Pricing Model
Sophos
I rated the contract terms and pricing structure a 9 because, overall, they were fair and competitive. The unit pricing for the Sophos SG Firewall was reasonable considering the features and performance offered, and the billing frequency was flexible, allowing us to align it with our budget cycles. However, one area that could be improved is the pricing for multi-year commitments—there could be more significant discounts or additional incentives for long-term agreements. Overall, the structure worked well for our needs, but some adjustments could make it even more cost-effective.

Scalability
Sophos
I rated the product's scalability a 9 because Sophos SG Firewall offers excellent flexibility and can be easily scaled across multiple departments and sites. It provides the ability to add more firewalls, manage them centrally, and integrate with other security solutions as our network grows. However, the only reason I didn’t give it a perfect score is that, in some complex environments, managing a large-scale deployment with many firewalls can become a bit challenging, especially in terms of centralized management and monitoring. Despite this, the overall scalability is highly effective for most use cases.
