Zscaler keeps us moving

5.0 7 months ago

Comments: We went from a VPN application that required users to reauthenticate every 10 hours on a mobile device and every 4 hours on a laptop for security reason, to Zscaler that we can allow users to reauthenticate every 30 days on mobile devices and every 3 days on laptops. The user experience has been improved tremendously. Additionally, the connectivity is more stable using Zscaler versus our previous application.

Pros:

Zscaler gives more security for the organization, while giving users more privacy. Analytics are hands down the best we have used. 10k+ users and we have had little to no problems since deploying Zscaler. Having the flexibility to change the duration for authentication while still maintaining a secure environment has made this tool a game changer for our users.

Cons:

Users initially had some confusion about the tool disabling when they were on a trusted network. Time and usage has helped to clear the confusion.

Zscaler is great solution when it comes to detect/prevent the thread within the cloud.

5.0 2 years ago

Comments: Overall Zscaler has brought the new generation in network security, and Zscaler made the other Security vendors to think in the different directions compare with thinking in traditional way. Zscaler kind of removed the network latency problems with traditional VPN solutions here Zscaler POP presence really helped.

Pros:

This is one of the best solution I have worked with, it provides the seamless experience better than the traditional VPN solutions. Connectivity speed is faster comparatively than the VPN solutions because of closer Zscaler POP availability. With speed you are also sure that you are sitting in Secure environment. As Zscaler also makes it sure no threats are touching the endpoint as well even the Zero day threats are detected and prevented within the Zscaler cloud.

Cons:

I had few problems with Zscaler ZPA solution, unable to resolve the DNS for private web. However all this got resolved as our team had worked with Zscaler support team.

zscaler, once configured correctly, makes vpn and internet access seamless

4.0 2 months ago New

Pros:

Private Access and Internet Security -- once configured and working -- works in the background with no user intervention. I can simply turn on my laptop, and be able to automatically VPN into my company.

Cons:

Many false positives and access blocked when zscaler was first introduced at our company. It took a while & after about 9 months, most of the issues were resolved.

I left a job I loved because of ZScaler

1.0 4 years ago

Comments: Let me start by describing what ZScaler is at its heart: a cloud-based network proxy that uses its own root certificate to inspect TLS/SSL traffic. If you are a company in the business of making software, keep this product away from your software developers. Far, far away. It does not play nice with many software development tools, even once you go through the pain of adding their root certificate in all the right places. I have spent hours and even days interacting with ZScaler support, often with no solution ever found. After spending months fighting frequent issues that came up, I finally threw my hands in the air and left my company. It probably works fine if you're just doing "regular" stuff with your network, like browsing, file uploads/downlads, etc. If you're doing anything more advanced, keep away from ZScaler.

Pros:

- Provides competent security and access for basic computing - macOS app works alright, although it does have plenty of hiccups

Cons:

- Hard to get it to work right with software development tools. In some cases, no proper solution was ever found. - Support is incredibly terrible. Unhelpful and wastes a lot of time. I really can't emphasize enough how frustrating the support was. I ended up just finding my own workarounds 90% of the time, after spending hours and hours on the line with support. - Adds latency, which can make profiling network operations difficult. - Sometimes you run into websites randomly blocking you or asking for CAPTCHA due to routing through ZScaler gateways.

Great for distributed teams, remote work, and VPN

4.0 4 years ago

Comments: We added this during the pandemic. We are in the process of doing the full company rollout, but we have a lot of users and this really helps us get visibility and security around our networked resources.

Pros:

I love that I don't have to use multiple VPNs to get to various parts of my company and product. Having Zscaler handle that all is really nice. Logging into SIEM is a lot, but good information and great for investigation. Love the agent. Works great for Windows and Mac

Cons:

Linux integration is in beta and I'm hoping it gets better. Setting up can be tricky, but professional services make it worth it.
