User Testimonials
Proofpoint Email ProtectionZscaler Internet Access
Likelihood to Recommend
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.

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.

Pros
  • 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.

  • 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.

Cons
  • The pricing is high and there are many licenses for things I feel should be part of other products.
  • The UI is slightly dated and has a lot of room for improvement.
  • The separate products should have one pane of glass for administration. Currently, if you own several of the products it feels quite disjointed when using them.

  • 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.

Likelihood to Renew
No answers on this topic
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
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.

Support Rating
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

Alternatives Considered
Proofpoint Email Protection allows configuration and granularity that far exceeds those features we'd been able to use with the Barracuda Email Security Gateway product. In addition, the robust Proofpoint reporting features give us and our decision makers much improved detail to make informed decisions about our security posture.

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.

Scalability
You can add a lot of agents to your environment if you need them. And you can operate hardware appliances and virtual appliances in the same cluster.

Return on Investment
  • 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.
Read full review
  • 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
