Web Protection

Choose your protection

Viper can help prevent connections to known malicious destinations using secure web protection. Choose Chrome Browser Guard or configure secure DNS on a supported device. This page cannot confirm whether your device is protected.

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 review the forthcoming iPhone app's supported call blocking and text filtering. The iPhone app and new paid plans are not publicly available yet.

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. Review your setup

    That's it. Known malicious domains can now be blocked for connections using this DNS profile. 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. Review your setup

    Known malicious domains can be blocked for connections using this resolver. Apps with their own DNS or a VPN may bypass it.

  1. Add the browser guard to Chrome

    ViperAI Shield — Browser Guard 1.0.1 is live in the Chrome Web Store. Add it to Chrome and a known scam or phishing site is checked as the page opens: a first visit is caught on arrival, and a site already known to this browser is stopped before it loads. The free web checker remains available for messages, links, and photos. The profile below filters connections that use the configured DNS.

    Add to Chrome — free
  2. Or configure Web Protection (Mac)

    Want DNS filtering on a supported Mac? On a Mac, download the Shield profile, then open System Settings → General → VPN, DNS & Device Management and install it — Quad9 secure-DNS filtering. Apps using their own DNS or a VPN may bypass it.

  3. Review your setup

    Known malicious domains can now be blocked within the browser or DNS coverage you enabled. Keep browsing exactly as before.

Honest about what this does

Web Protection uses DNS filtering. It does not hide your IP address, change your location or encrypt all device traffic. It is not a VPN.

This can block 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 — use native parental controls where supported. This profile alone does not prevent removal.

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, does not retain individual user IP addresses. It processes DNS questions and retains some aggregate security telemetry; see Quad9’s privacy policy.

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.
