HI Vekatesth,

None of our azure resources have public IP addresses as it's a security risk to have them accessible over the public internet.

I think only the firewall has a public IP address.

And pretty much all inbound traffic is blocked. And a great majority of outbound traffic is also blocked.

We use Azure front door to expose resources to the internet, and even that is severely limited because only it reaches a web application firewall before reaching any of the servers over a load balancer.

Hi Venkatesh,

I would like to go with first option that using run command on single virtual machine first.

Please clarify below :

I should execute following highlighted command as it is, right? or any modifications needed ?

May I know why it did not work my command showing in my first thread , so that I can explain to management about executing command you have shared.

After executing your command, do I need to execute any series of commands? also let me what is the verification command to check whether successfully verified or not?

Looking Forword for your response.

@sns Thanks for your follow-up questions.

The cmdlet you have highlighted in the screenshot to install the falcon-sensor from the remote machine or through the cloud shell.

Looks like we need to have crowdstrike account to install the falcon sensor I dont have the access and I havent tested in my local.

To test whether the falcon sensor is running or not you can run the cmdlet ps -e | grep falcon-sensor

HI Venkatesh,

So what needs to be done and which command I supposed to execute to get rid of above error?

I have crowd strike account already and it worked for another subscription but for this prod subscription it is giving error.
