    Proofpoint
    Well suited: Proofpoint does a pretty good job at protecting us from spam emails. I was able to block a lot of emails coming from SendGrid by blocking SendGrid emails with a custom spam filter. However, SendGrid has a lot of legit emails too so I was able to create another rule to allow those emails from certain people, then block the rest. That way business need was met but spam emails are blocked. Less Appropriate If you are trying to monitor internal to internal emails Proofpoint is probably a little over featured for that.

    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
    Proofpoint
    • Spam - catches these emails before hitting the inbox.
    • Daily digest - provides users with a list of the emails that were blocked and allows them to choose to release them if they are legitimate emails.
    • Ensures that emails coming into our organization is safe for our users and verifies the email is coming from stated senders email server.

    • 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
    Proofpoint
    • Proofpoint could offer more frequent training opportunities to customers at all levels of expertise.
    • Proofpoint can always continue to strive to keep its product a leader in the industry.
    • Proofpoint's support site could be overhauled to provide a more logical flow.

    • 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

    Zscaler
    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.

    Very robust and solid product in protecting our emails. The engineers who assisted with our implementation was very knowledgable and great to work with. Easy to use by end-users. Administration and management are also easy for IT. Great dashboard and reporting tools for business reviews.

    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.

    We use ProofPoint support quite often to fix issues and assist with setting up features and rules. Each time we have created a ticket, they have been very helpful and respectful. Each ticket has been treated with the appropriate SLA time and attention. We also enjoy the regular check-ins from the engineers when tickets are open but we get busy with other tasks.

    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

    We previously used halon anti-spam, which lasted us well until our organization really started to grow and it was not able to keep up with the amount of mail we were receiving. The support is also nothing compared to Proofpoint's professional services offering. Halon was also not able to have the complex rules that Proofpoint can offer.

    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.

    Return on Investment
    Proofpoint
    • Having easy-to-reach backups of all employee emails has made Proofpoint worth it by itself. That plus the countless times that spam/malicious emails did not make it through to the intended person that could have potentially cost the organization a lot of money.
