Cybersecurity threats, especially ransomware, are constantly evolving, so it’s important to regularly audit your ESXi hosts to ensure they have the proper protections enabled. Today I want to share a simple but effective PowerCLI script, Get-RansomwareProtectionStatus, that quickly checks your VMware hosts for important ransomware-related security configurations.
🚀 What This Script Does This script focuses on three key settings that enhance protection against ransomware on your ESXi hosts:
Encryption Mode: Checks whether TPM-based encryption is active.
Secure Boot Enforcement: Confirms Secure Boot is enabled.
Exec-Installed-Only Mode (Configured & Runtime): Ensures only binaries from installed VMware VIB packages can execute.
Having these settings properly configured greatly reduces the risk of unauthorized code execution—exactly what you want to fight ransomware!
🔧 How to Use the Script
Here’s how simple it is. First connect to your vCenter and then run a script.
.\Get-RansomwareProtectionStatus.ps1 <HOST>
It generates a clear, colored summary, instantly telling you what’s secure and what needs your attention.
You can integrate this script into your monitoring routines, run it on multiple hosts with automation tools like Ansible Semaphore or GitLab CI, or even schedule regular audits.
⚡ Pro Tip: Save your reports to a file or push results directly to your monitoring dashboard to track security over time!

The VCF Download Tool is a handy CLI that makes grabbing and managing VMware Cloud Foundation (VCF) bits a breeze. You’ll get commands to download, upload, list, and clean up binaries and metadata for your VCF releases, plus easy setup, teardown, and running of the Update Manager Download Service (UMDS). In short, it’s your one-stop utility for getting VCF artifacts ready and keeping them in shape.
Where to start
Prepare correct download token which belongs to Site ID in Broadcom portal, where is valid VCF licences. Otherwise it fails to download. Save the token to txt file in your home directory for example “downloadtoken.txt”. I am doing all the commands on linux machine. For windows follow official KB https://knowledge.broadcom.com/external/article/401373/vcf-download-tool-under-windows-os.html which will guide how to install WSL (Windows subsystem for Linux) and you can continue with next step.
Download & Extract the VCF Download tool
I created directory in my home folder called “vcfd” ( “mkdir ~/vcfd“. Then I download the VCF Download tool “vcf-download-tool-9.0.0.0.24703747.tar.gz” from broadcom.com website into the “vcfd” folder. Also I moved my “downloadtoken.txt” into the “/data” folder “mv ~/downloadtoken.txt /data“
Extract the tar.gz file
Go to the “vcfd” directory with command “cd ~/vcf” and extract the vcf-download-tool-9.0.0.0.24703747.tar.gz archive.
tar -xf vcf-download-tool-9.0.0.0.24703747.tar.gz
VCF Downlaod Tool CLI usage
to get basic help just run the command “vcf-download-tool” without parameters or with “-h” or “–help”.
./vcf-download-tool -h
*********Welcome to VMware Cloud Foundation Download Tool***********
Version: 9.0.0.0.24703747
Usage:
vcf-download-tool [-hv] [COMMAND]
Description:
The VCF Download Tool is a command-line interface (CLI) utility designed to simplify the management of binaries and metadata for VMware Cloud Foundation (VCF) environments. It provides a suite of
commands for downloading, uploading, listing, and cleaning up binaries, enabling efficient management of software components for VCF releases. The tool also supports the installation,
uninstallation, and execution of the Update Manager Download Service (UMDS). With its comprehensive features, the VCF Download Tool helps streamline the process of preparing, managing, and
maintaining VCF-related artifacts in your environment.
-h, --help Displays a help message that provides information about the command and its available options, and then exits the tool.
-v, --version Displays the version information of the VCF Download Tool and then exits the tool.
Commands:
binaries Management of the binaries files within the system.
metadata Management of the metadata files within the system.
releases Operations related to the VCF releases.
umds Manage the installation and execution of the UMDS (Update Manager Download Service) tool.
More help
pick one of the command “binaries|metadata|releases|umds” and add “-h” at the end. For example:
./vcf-download-tool binaries -h
*********Welcome to VMware Cloud Foundation Download Tool***********
Version: 9.0.0.0.24703747
Usage:
vcf-download-tool binaries [-h] [COMMAND]
Description:
Management of the binaries files within the system.
-h, --help Displays a help message that provides information about the command and its available options, and then exits the tool.
Commands:
download Download all the necessary files. The command supports filtering to narrow down the selection of binaries based on the customer intent. At least one filter is required. In
addition to the binaries, it also downloads all of the needed metadata. However, UMDS binaries are excluded from the download. When executed multiple times with the same
output directory, the command’s behavior is cumulative, adding to previously downloaded binaries without overwriting them.
upload Uploads the downloaded binaries into the SDDC Manager. In addition to the binaries, it will also upload the necessary metadata, ensuring that all relevant information is
properly integrated into the SDDC Manager system. As a prerequisite, the downloaded binaries need to be transferred to the SDDC Manager appliance and the command must be
executed from within the SDDC Manager appliance.
list Provides a comprehensive view of all available binaries. Similar to the download binaries command, it supports filtering options to help you narrow down the list based on
your specific needs. At least one filter is required. When executed, the command will display detailed information for each binary, including key details such as the
component name, version number, release date, size and type. This allows you to quickly assess the contents of the depot, making it easier to identify which binaries are
relevant to your requirements before downloading.
cleanup This command helps you efficiently manage disk space by removing unwanted or obsolete binaries, while retaining the ones you still need. It ensures that only the selected
binaries are deleted, giving you full control over what remains on your system. It is designed to be run on a system where binaries have already been downloaded.
create-download-spec Generates a download specification file based on the planned upgrades for a specific domain within the environment. This spec file contains the necessary details to identify
which binaries are required for the planned upgrades. Once created, the spec file can be used as an input parameter for the download binaries command, ensuring that only
the relevant binaries for the upgrade process are downloaded. The command must be run from within the SDDC Manager appliance, as it relies on the environment's upgrade
plan to generate the correct spec file. This streamlines the download process by focusing only on the needed binaries for the upgrade.
1) Downlaod VCF files needed for VCF installer offline depot
2) How to download all VCF files with VCF download tool.
1) Download VCF files for VCF Installer
This will download only files needed by VCF installer for offline depot. To download all skip to next chapter 😉
Be aware that it will download all required files for full VCF 9. installation. In my case it requires around 82GB on disk(folder). And my target destination for the downloaded files will be /data folder where is 100GB free space.
Start downloading VCF 9 files.
You need to specify what you want to do (download) , the version, depot download token and destination. Token needs to be in txt for example “downloadtoken.txt”
cd bin
./vcf-download-tool binaries download --vcf-version 9.0.0 --automated-install --depot-download-token-file=/data/downloadtoken.txt --depot-store=/data
Progress / Output
root@workstation:/data/bin# ./vcf-download-tool binaries download --vcf-version 9.0.0 --automated-install --depot-download-token-file=/data/downloadtoken.txt --depot-store=/data

Managing virtual network interfaces (vNICs) effectively is crucial for VMware administrators who want to optimize their virtual infrastructure. It’s important to note that modifying a VM’s in-guest virtual networking adapter link speed addresses OS or application-level limitations related to the default detected 10Gb speed of the vmxnet3 adapter. However, keep in mind that the actual network speed available to the VM is still limited by the physical hardware components, such as the host CPU and physical NICs.
Introducing the vNIC Link Speed PowerShell Script
I’ve developed a straightforward PowerShell script leveraging VMware’s PowerCLI to automate setting vNIC link speeds for your virtual machines.
How It Works
This script allows you to:
Select your virtual machine by name.
Choose the desired link speed (10,000 Mbps, 25,000 Mbps, 40,000 Mbps, or 65,000 Mbps). You can modify this script and set the speed between 10,000 Mbs and 65,000 Mbs.
Verify the power state of the VM and optionally power it off safely.
Automatically apply the new link speed settings to all vNICs of type vmxnet3.
Check and confirm the applied settings.
Requirements
Before you begin, ensure you have:
VMware PowerCLI installed and connected to your vCenter server.
Administrative privileges on vCenter and your VMs.
Usage Example
Here’s how easy it is to run the script:
PS> .\vNIC-LinkSpeed.ps1
The script will prompt you to enter the VM name and select your desired link speed from a simple menu. Verify the power state of the VM, prompting you to shut it down if necessary. If you choose not to power off the VM, the script will exit.
script output
In my case I change the link speed for my virtual ESXi.
Why Use This Script?
Efficiency: Automates repetitive tasks, saving you valuable time.
Reliability: Ensures consistent configuration across all vNICs.
Flexibility: Easily adaptable to any environment and extendable for future requirements.
Download and Customize
You can download and customize the script from my GitHub repository https://github.com/musil/vSphere_scripts (direct link to file -> vNIC-LinkSpeed.ps1 ), or copy it directly from this blog post and adapt it according to your specific needs.

If you’re managing VMware environments, you might occasionally run into persistent shell warning alerts in your ESXi hosts. Thankfully, you can quickly find and suppress these warnings with a bit of PowerCLI magic.
Check for ESXi Hosts with Shell Warnings
Show the actual advanced settings on all hosts. Log into vCenter using PowerCLI and run this command:
This command immediately disables the shell warnings on selected hosts. No more alerts in GUI!
Command output:
Entity Name Value
------ ---- -----
fs-vsan-05.int.dc5.cz UserVars.SuppressShellWarning 1
Why (Not) Suppress Shell Warnings?
It’s important to note that suppressing shell warnings is only advisable in lab or non-production environments. In production environments, shell warnings provide valuable security reminders. Always keep shell warnings enabled to maintain security awareness unless you’re working in a controlled test environment.
Managing encryption across multiple ESXi hosts can be a bit of a hassle. But don’t worry. I’ve got a simple PowerCLI script that’ll save you time and headaches by quickly retrieving encryption status and recovery keys from your VMware environment.
Why Do You Need This?
Ensuring your ESXi hosts are correctly encrypted is essential for security. Regular checks help prevent surprises later, especially during troubleshooting or audits.
Getting Started
First, make sure you’re connected to your vCenter:
Connect-VIServer -Server
Replace with your vCenter IP or FQDN.
The Script Breakdown
Here’s a quick rundown of the PowerCLI script to verify encryption settings across all ESXi hosts and who Recovery key for each ESXi host. (link to GitHub repository and file tpm_recovery_key_backup.ps1):
