    Sophos Email is ideal for protecting business email from advanced threats. It comes with features that make it easy to detect and block email threats, such as spam, phishing, ransomware, and data leaks. In addition, Sophos Email is ideal for email encryption and helps train teams to identify phishing threats.

    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.

    Pros
    Sophos
    • We could customize it to have a certain level of workflow. We manage to enforce certain email (based on key-phrases) to be quarantined before send it to the recipient. And the email needs to be approved (manually) before being released.
    • For certain type (using regex) of email, we will encrypt it if it's sent outside our organization domain.
    • Scalable

    • 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.

    Cons
    Sophos
    • I would love to see tips integrated into the user interface from the management side to allow for easier dissection of email headers. This would allow lower level admins that may work at smaller companies to better understand the information presented.

    • 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).

    It was easy to use and easy to implement. You don't need previous knowledge on the products, after we got this up and running, it took us hours to put everything together. The transition was easy and seamless.

    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
    It's mostly great and for policies and features, it does everything we would ask it to and more. The only thing keeping it from being a 10 is the lack of granularity in the reporting, which is actually an issue within Sophos Central as a whole. The ability to drill down from dashboards into accurate, detailed data would be very helpful at times.

    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.

    Support Rating
    Sophos
    Support is slow to respond. They call back outside of normal business hours despite clearly being advised when they should call. They try to BS you that the platform is working properly although there is hard evidence to the contrary. Once you get to senior level of support they agree that the product is incapable of performing properly in its current iteration.

    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

    Many other solutions are a complicated setup and take a lot of time for the configuration. With Sophos email we were setup and seeing data/emails within an hour. As I have described the ease of use from a high-level for someone like me a Director just peeking into the system or an analyst that can do a deep dive is one of the best users interfaces I have seen for any product.

    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.

    Return on Investment
    Sophos
    • AI-powered email threat prevention ensures that no threats reach our email system, preventing data contamination.
    • The BEC defense ensures our business reputation remain in place.
    • URL protection protects our users from clicking on malicious links that would otherwise compromise our email systems.
    • Ability to encrypt emails keeps our email data secure which a plus.

    • 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.
