Proton Mail vs. Zscaler Internet Access

Good if you like privacy and not having your data mined for advertizing and AI training.

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.

• Secure encrypted email hosting
• Connection with Outlook works well
• Works well on all platforms: web, Windows, MacOS, Android, iOS
• Low monthly cost for email plus all the associated apps

• 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.

• Exporting email (which I like to do for archiving) is awkward and slow.
• Proton Mail Bridge (which allows access from other email readers like Outlook) sometimes has synchronization issues. Lately these just resolve themselves.

• 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

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.

Mostly intuitive and easy to use. A bit harder if you stick with two passwords (one for the account and one for the encryption).

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.

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

Proton had a wider offering of products like vpn and drive. I ended up paying for a yearly subscription, I liked it so much.

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.

• Easy to link with my business domain and email.

• 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
