Use Cases and Deployment Scope

We use it for URL filtering, creating policies around risky web sites and policies around media entertainment sites so that we can limit the sites that users can visit and/or limit the actions that users can take on specific sites such as YouTube with an upload action limitation. We also use it to view and analyze user behavior to direct future policy decisions.

Pros

URL filtering
Internet access policies
User action limitations

Cons

User Interface could be a little better
The activate button when making changes could be better, activate seems somewhat like a misnomer especially to newer admins/engineers to the product, a more accurate word would be publish.
Blocked action message for the user could be more user friendly

Return on Investment

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

Jay Yoshizumi

VP Infrastructure in Information Technology at KA (51-200 employees employees)

Use Cases and Deployment Scope

Replaced web filtering on the firewall and openDNS with this solution. It gave us the ability to see what users are doing both in the office and remotely.

Pros

No need to be in the office.
1 agent.
SSL inspection.

Cons

Not a lightweight app when combined with ZPA.
An agent can pick a foreign data center when close to the border.

Return on Investment

Installation was not smooth.

Ed Freels

Sr Systems Engineer in Information Technology at Global Partners LP (201-500 employees employees)

Use Cases and Deployment Scope

Deployed across 1500 users to provide user internet activity visibility and impose controls as needed to enforce published policies.

Pros

Aggregation of deployed base internet usage.
The ability to create and apply URL & cloud policies to those users.
Reportable metrics on internet access as a whole.

Cons

Sectional exports & reports. For example, provide the CIO with Zero Trust "holes" because of "sacred cow" users. It'd be nice to generate reporting or even CSV exports for that data for easier communication.
Tenant resolution - regardless of my physical or logical location, the ZIA tenant landing always takes longer to resolve than one would think.

Return on Investment

We just turned off the general VPN this week, post Zscaler rollout of ZPA & ZIA, but it's still the "new" kid on the block, so "everything" is a Zscaler issue.
The ZIA implementation revealed to us exactly how inadequate our internal policies regarding internet access are. Instead of leveraging the tool to reduce risk factors, we find ourselves adjusting ZIA policies to accommodate user complaints rather than adhering to company policy enforcement.

Use Cases and Deployment Scope

we are using Zscaler Internet Access to help secure our users internet data exposure and enforce compliance to company policy. WE have had issues with staff accessing un secure sites under the pretence of trying to do work however this was not the case.

Pros

easier deployment
the reporting is great
the ease of use for back end users helps manege things better

Cons

the training material is not great
having a high level overview of all platforms under one screen would help

Return on Investment

compliance protection
current negative due to complexity in deployment alongside Palo

Use Cases and Deployment Scope

It has removed the burden of the internal infrastructure and improved latency. We have noticed that the user satisfaction and user experience has improved as well. What we have enjoyed most has been that we can remove the dependency of some segmentation efforts and reduce the endpoint burden of configuration sets.

Pros

Efficiency
Reliability
Simplifying.
Security

Cons

Localizing the network
More protocol support
Less impact to OT devices like PLCs

Return on Investment

Reduces our threat landscape
Reduces the footprint of technology devices
future proofs the segmentation and network hardware
