About

What it is: NXTL Shield is a set of free, open-source security tools from NXTL eSIM, built as a static web page. It checks a link or message, shows your connection, helps you turn on Safe DNS, encrypts files and messages, and sends private links that vanish once opened. It asks for no account.

Who it suits: Ordinary users who want quick safety checks and private sharing without signing up or installing a security suite.

Industry | Who uses it | How they use it | Example
Everyday security | Home users | Check a suspicious message before replying | A lottery message that asks for details
Privacy | Cautious users | Send a file or note that is not kept after it is opened | A private link to a document
IT support | Helpers for family and friends | Walk someone through Safe DNS setup | A Windows setup screen
Travel | Frequent travellers | See what their connection looks like | A hotel wifi check

If you already run a full security tool chain, you can skip it.

Where to use it:

• A web browser, on the Space's page at Hugging Face
• Windows, macOS or Linux, opening index.html from a downloaded copy
• The README shows a Windows Safe DNS setup screen

Use case | Who | What they get back
Scam check | Anyone | A message or link marked as a likely scam or not
Connection check | Travellers | A page showing your connection details
Safe DNS setup | Home users | Steps to turn on Safe DNS on their device
Private sharing | Anyone | An encrypted file or message, or a link that is gone after opening

How to set it up:

• A web browser
• No account is needed
• Python only if you want to download the files to your computer

1. Install the Hugging Face hub package.
2. Download the Space with the hf command.
3. Move into the downloaded folder.
4. Open index.html in a web browser.

pip install -U huggingface_hub
hf download nxtl-esim/nxtl-shield --repo-type space --local-dir nxtl-shield
cd nxtl-shield

How to use it: Open the Space page, or index.html from your copy, and pick the tool you want from the home page. The README shows screens for a message check, your connection details, a Windows Safe DNS setup and private messages and files.

Tool | What it does
Check a link or message | Rates it, for example marking a lottery message as a likely scam
Your connection | Shows details about your connection
Safe DNS | Guides you through turning on Safe DNS, with a Windows setup screen
Private messages and files | Encrypts them, or makes a private link that disappears once opened

Example: You paste in a message that says you won a lottery and run the check. The README shows such a message coming back marked as a likely scam.

For newcomers and experts: Start with the message check, since it needs nothing set up. Paste in a message you are unsure about and read the verdict.

The repository is a static site with 136 files, including a service worker file, a web manifest, lists, icons and a downloads folder. The source does not say where checks run or how one-time links are stored, so read the code before trusting it with sensitive files.

You open the static page
You choose one of the security tools
The tool checks or encrypts your input
You read the result or share a link

Good to know:

• Built as static HTML, so there is nothing to install to use it online
• License: gpl-3
• Cost to run: none named, and no account is required
• Data it reaches: the links, messages, files and connection details you use it on
• Not for: sensitive material, until you have read how it stores and sends data, which the source does not explain
