Automatic protection

Turn on ViperAI Shield

Once it's on, known scam, phishing, and fake-bank websites are blocked before they can even load — on your phone or your computer. Setup takes about two minutes and it's free.

Honest scope, so you know exactly what you're getting: this free profile automatically blocks scam websites. Scam calls and texts still arrive — check those in seconds with the free checker, or the iPhone app's paid plans filter them automatically.

Turn on protection

On iPhone or iPad, tap the button, then follow the steps below.

  1. Tap "Turn on protection" above

    Your phone will ask to download the ViperAI Shield profile. Tap Allow.

  2. Open Settings

    Close this page and open the grey Settings app. Near the top you'll see Profile Downloaded — tap it.

  3. Tap Install

    Tap Install in the top-right, enter your passcode if asked, and tap Install again to confirm.

  4. You're protected

    That's it. Scam and phishing sites will now be blocked on this phone. You can keep using it exactly as before.

  1. Open Settings

    Open the Settings app on your Android phone.

  2. Find Private DNS

    Go to Network & internet → Private DNS. (On some phones, search "Private DNS" in Settings.)

  3. Enter the Shield address

    Choose Private DNS provider hostname and type: dns.quad9.net — then tap Save.

  4. You're protected

    Scam and phishing sites are now blocked on this phone. Nothing else changes.

  1. Add the browser guard to Chrome

    Coming soon: scam and phishing sites blocked before they load, right in your browser — Chrome, Edge, and Brave. Until it ships, the free web checker is your computer's protection, and the profile below covers the whole machine. (Kids' AI-app blocking is a Family-plan feature in the iPhone app.)

    Add to Chrome — free
  2. Or cover the whole computer (Mac)

    Prefer every app protected, not just the browser? On a Mac, download the Shield profile, then open System Settings → General → VPN, DNS & Device Management and install it — the same Quad9 secure-DNS protection as the phone.

  3. You're protected

    Scam and phishing sites are now blocked on this computer. Keep browsing exactly as before.

Honest about what this does

This blocks websites that are known to be scams — it's a strong layer, not a force field. Always still check anything that asks for money or passwords. The free scam checker is there for anything a blocklist hasn't caught yet.

It protects the phone you set it up on. Setting it up on a family member's phone means doing these steps on their phone. And because you turned it on, it can be turned off the same way — to keep it locked on a child's phone, use Screen Time.

Is this safe to install?

Good instinct to ask — you should be suspicious of anything that wants to change a setting on your phone. So here's exactly what this is, in plain terms: the profile points your phone's DNS (the internet's address book) at Quad9 — a free, non-profit secure resolver run by a Swiss foundation and used by tens of millions of people. It blocks known-malicious websites and, unlike most, keeps no logs of where you go and never sells your browsing.

ViperAI never sees the pages you visit. You turned it on, and you can remove it yourself any time (steps below). One tell: if a surprise "tech support" call ever pressures you to install a profile, that's the scam — this is something you choose, on your own, and control.

To turn it off later

iPhone: Settings → General → VPN, DNS & Device Management → ViperAI Shield Protection → Remove. Android: Settings → Private DNS → Off.
