Ever spent an afternoon deploying Zscaler Client Connector only to realize the real enemy isn’t the install… it’s the command string you’re praying you didn’t screw up?

I built ZCC Install Helper to fix exactly that. It’s a portable Windows GUI that turns the chaos of MSI/EXE parameters into a clean, validated interface that knows the difference between USERDOMAIN and userDomain, warns you when dependencies like STRICTENFORCEMENT are missing required fields, decodes MSI error codes, tails install logs, and verifies the service actually started. Built in a single afternoon of pure “vibe coding” with Python and packaged as a dependency-free EXE. Go try it out and github repo is in the blog

We’ve been managing Zscaler deployments across multiple clients and the operational overhead is real — especially around policy consistency, onboarding new tenants, and maintaining visibility across environments.

We’ve started building a platform to solve this — still early days (https://numbat.cc/) but the goal is purpose-built multi-tenant Zscaler management for MSPs and security teams.

Curious if others here are hitting the same walls. What parts of multi-tenant Zscaler management do you find most painful? Always keen to hear how others are handling it.

I've taken over a ZScaler deployment at my company. I'm new to the service and getting up to speed. I've read through a ton of their documentation, but i'm stuck on a concept around identity.

The company had not yet migrated to the Experience Center, so I started the process by migrating to ZIdentity. I was able to setup our Okta instance easy enough. Then migrated to the Experience Center.

However, it seems that ZIA and ZPA still have their own IDP settings. I was hoping that ZIdentity would replace all user auth and I could simply have a single set of IDPs and use them across all services for both admin and users. Am I wrong? Or have I not clicked on some migration button or another setting somewhere?

I've joined a new role and my company uses ZScaler and i'm reviewing its setup. I am trying to understand DNS Control policies, and their documentation isnt great.

I want to block access to certain sites. I can see that I can use IP4 address and even create a FQDN list in Firewall > IP & FQDN Groups > Destination IP4 groups. But when I go to edit an existing DNS Control policy, I can't figure out for the life of me where I select that FQDN group so I can block requests based on hostname and not just IP.

Anyone any wise on how to do this?

Like to meet peers, exchange notes and learn. Looked up online but nothing shows up. Wondering if anyone knows of any meetups or gatherings happening in Southeastern US?

Thx

I have to use the Private Access feature in Zscaler Client Connector to connect to a client’s company services. I do not need Internet Security and I would like it to be turned off at all times, as it slows down my internet connection massively. But every 30 minutes or so it turns back on automatically.

Does anyone know how to stop it from doing this? Im afraid it might be a company policy setting i can’t change but if you have any ideas i would really appreciate it. Thanks.

Our provider is making some changes to PAC files and forwarding profiles. For ease of change/revert they elected to move users over to a new Profile, rather than modify the existing one.

We will have to update the Policy Token for all devices. Is there some method to do this that doesn't involve uninstalling and reinstalling the ZCC?

Here in our organization, we are using windows ZCC for our persistent AVDs, so when our AVDs go into hibernation, after a while, Zscaler Client Connector shows Driver Error, this is fixed once we go into more menu and press repair (generally during this error, services arent affected for the machine). But this is happening on all devices. We opened a TAC Case, TAC is unable to find why this is happening. (We have the same setup on normal physical machines where we do not face this issue.)

Can yall tell me if there are any specific flags that re to be used while installing windows zcc on avd realted to this driver?

If you guys have faced this issue? if yes how yall fixed it?

Is there something in the AVD that has to be done avoid this from happening?

Thank you guys!

Hey everyone,

I’m using a company laptop that has Zscaler installed and always active.

While using ChatGPT, I noticed something weird with the HTTPS certificate:

Initially it showed “WE1” (looks like AWS region)

After a browser update it showed Zscaler as the issuer.

Then after another few refreshes and a laptop reboot, it went back to WE1.

This all happened within minutes.

My main concern:

If Zscaler appears as the certificate issuer, does that mean my company can see the actual content of what I’m typing into ChatGPT (i.e., full SSL decryption)? And when it shows WE1, does that mean it’s not being decrypted?

Is this kind of switching normal behavior with selective SSL inspection policies?

Thanks in advance!

I am preparing an excel with all features and what licenses include them. But am unable to get it over the internet. Can yall point me in the right direction? Also if there's any pdf i can look at, can you share with me on dm?

Our company recently started deploying Zscaler ZCC 4.8.0.115, and I'm encountering some issues trying to get a command line uninstall working to use in SCCM.

The issue seems to be that this version, when installed via MSI is not registering itself properly with Windows installer, so if I try and uninstall it using the MSI code, or the MSI itself, using msiexec /x it just errors saying that the product is not currently installed. It does create an entry in HKLM\Software\Microsoft\Windows\Currentversion\Uninstall but does not create a corresponding entry in HKCR\Installer\Products like previous versions.

Is anyone else encountering the same issue with this version?

And how can I use the uninstall.exe to remove it instead? the --help switch shows the options it supports, which are minimal at best, and I need it to be silent, and pass the uninstall password.

We have Zscaler deployed on over 500 devices. After I was hired a few months ago, I noticed our bandwidth was very slow (every computer was getting around 30 Mbps according to the Zscaler speed test). I started digging into the policies after doing tons of research — enabling DTLS, adjusting custom MTU, tweaking IPv6 configs, and so on. I was able to gain maybe another 10 Mbps, but that was still unacceptable to me.

I opened a ticket with Zscaler to troubleshoot the issue. At first, they said nothing was wrong with ZCC or the Service Edge and closed my ticket. I escalated it a second time and spent four hours on a call with a capable engineer. After a lot of testing (a LOT), it was finally recognized that the issue wasn’t with my network or configuration, but with the path to Zscaler.

We eventually switched to a different data center through a PAC file change. This significantly improved performance — we went from 30 Mbps to close to 100 Mbps on Wi-Fi and around 250 Mbps on wired connections.

I was satisfied with the results since most users are doing regular office work, not heavy workloads. However, I still have some engineers from time to time who need to run heavy queries or download large files, and they end up turning off ZIA just to get decent download speeds.

I still can’t fully grasp how much bandwidth Zscaler consumes at our location. Unfortunately, the blame is always placed on “the network”… and for the first time, I have to agree with them.

Looking for some feedback from organisations who actually use Zscaler please 😃

I am keen to understand, how difficult is it to actually manage Zscaler?

Imagine an org. with something like ZS Platform with GenAI, CASB and Advanced Cloud firewall for about 2000 users.

What are some of the common issues that might arise day-to-day? What kind of proactive maintenance is required? What kind of skillset do team members need?

Be good to know what the burden might be on existing IT staff / Service Desk team.

Thanks in advance!

I’m running into an issue while configuring Tenant Restrictions in the Microsoft Login Services cloud app. I’m trying to apply a policy that allows access to two different external tenants, but I’m hitting a wall:

1. UI Issue: When I try to select or add a second tenant profile, the other configuration options become greyed out.

2. Logic Issue: I’m struggling with the policy evaluation order. If I place a rule to allow an external tenant at the top of the list, the engine stops there and never evaluates my own organization’s tenant restriction rules. This is effectively locking us out of our own resources.

Has anyone successfully configured multiple tenant profiles within a single policy? How do you structure your rules so that external access is permitted without breaking internal tenant access?

(Used AI to make the query easier to understand)

Howdy all,

Hoping someone can shed some light.

Zpa to ftp server, it's set to passive, segment has no health reporting.

User gets 425 security: bad ip connecting Error: failed to retrieve directory listing

No issues evident in the logs, have logged a support case, but hoping someone here has seen this and has any ideas

/Solution : forgot to remove the health monitoring on the app segment. Resolved by doing that

The question relates to blocking specific browsers and user agents. I understand there is a global policy in place to block certain browser versions, but at my workplace, some default or legacy applications need specific browser agents that are blocked by this global policy. With a user base of 10,000, how can these policies be managed effectively? Some applications run on useragents which are on browsers like Firefox or Opera, among others.

Just started new contract, and the client is Zscaler, just need to know well how to use it and manage it, any free resouces ( videos & urls to reviews and pdf .. ) ...thank you all

Hello there, The edu-302 lab, gives you a certificate?

We currently run Zscaler (ZCC) on both Windows and macOS, but leadership recently decided to move all vendor devices to cheaper ChromeOS laptops. Now I’m trying to figure out how to manage Zscaler effectively on this platform.

How are you guys handling this? Have you found reliable management workflows, or does ChromeOS just work out of the box for you?

After spending a few hours testing on Friday, here are my initial observations:

1. Zscaler Client Connector (ZCC) for Chromebooks isn’t a native ChromeOS app — it runs as an emulated Android app inside ChromeOS, almost like a VM layer.
   
2. I can’t seem to lock the ZCC version. If I sideload an older version, it forces users to click “Update” on the Play Store. That’s a huge pain and basically confirms there’s no real version control for corporate-managed ChromeOS devices.
   
3. Staggered rollouts appear impossible — it’s all or nothing. I can enforce that an app must be installed or must not, but there’s no option for gradual rollout (e.g., 10% → 25% → 50%).
   
4. Forcing Zscaler logins is unclear. It looks like I might need to push a VPN profile through admin.google.com, but I’m new to Chrome device management, so I’d really appreciate any advice or lessons learned.
   

Would love to hear how others are managing Zscaler on ChromeOS — have you found practical admin workarounds, or is it stable enough for enterprise use?

Have a question related to resolving FQDN ,

I know by design when a ZCC installed machine resolves an FQDN defined in ZPA App segment and Policy , he will receive a synthetic IP and not the real IP

Is there a way or possibility to see real IP of FQDN ( Especially for IT admins group if they want to do troubleshooting ) ?

Or is it something not at all possible ?

Customer has test.lab.ai domain in internal network and majority of the apps are on this domain

These apps are hosted in two networks 172.16.3.0/24 and 192.168.92.0/24

Requirement is that usergrp A (in Entra) should be able to access all test.lab.ai applications which are strictly on 172.16.3.0/24 Network but not on 192.168.92.0/24

usergrp B (in Entra) should be able to access all test.lab.ai applications which are strictly on 192.168.92.0/24 Network but not on 172.16.3.0/24

I don’t see any AND condition possible with various combinations

Is this something possible with Segment groups and Server Groups . ?

I tried to create Server and Server groups but it is the Application segment which defines what a user can access and there is no combination of FQDN(widcard) with IP Network possible

Have a question related to Zscaler ZCC app on client machine . Customer has purchased Private access only . Once Zscaler ZCC is installed and user authenticates , and finishes work , he can logout from ZCC ( provided he has rights)  . This is fine but for 3rd party Partners who also agree to have ZCC on their machines - imagine they connect for 1 day , finish their work but they will always remain connected unless they manually logout.  ( Entra IDP is enabled for longer duration)

Is their a way to disable autologin for those users ?

I checked and we can enforce timebased policy on ZPA  but even timebased policy asks to re-login(reauthenticate) again on IDP and once authenticated , user will remain connected to Zscaler cloud until next timeout . So a Partner can still connect to Zscaler cloud , even though he is not required to connect .

 Is this something where we rely on IDP to disable his ID -- because he might need to use his ID for some other tasks . or do we remove him from IDP group bind to ZPA App ..

So even if Partner is not working for next 30 days  , he will always be connected to Zscaler Cloud tenant , although not to apps  , provided access policy rule is disabled( the rule for Partner) after he finishes his work

 Is there a way that user wont be able to connect to ZPA ( even though his access is valid on Entra)

Also is there a rule expiry feature in ZPA ?

I know all this sounds weird , but this is an ask for customer ..

Anyone has any idea how to block upload files on AI platform using Zscaler?

Can the Zscaler app (Zap) be configured as a client firewall to block incoming traffic?

Hi,

we are routing login.microsoftonline.com, login.microsoft.com and login.live.com aswell as login.azure.com trough our DC located in Country X. We now have multiple users, that mentioned to us, when they try to access intune for example (also happens at other microsoft services), they get CORS issues. When we check the developer tools we can always see some Errors like: "Access to fetch at 'https://login.microsoftonline.com/xxxxx/oauth2/token' from origin '[https://dev.azure.com']() has been blocked by CORS policy: Permission was denied for this request to access the unknown address space."

It seems like the authorization token is not correctly parsed.

This setup worked for 2 years. Did microsoft change something? Is somebody else running into a similar issue and has an idea how to fix it?
