Before you start

A Windows 10 or 11 PC that stays on, at the location you want to protect.
Connected to that network — a cable is best, Wi-Fi works too. Not a guest network.
A PhylaxNet account — create one free.
Administrator rights on the PC (needed to watch network traffic).

Install in 6 steps

  1. Download the installer

    Click Download for Windows above. The file is called PhylaxNetSetup-x.x.x.exe.

  2. Run it

    Open the file from your Downloads folder. If Windows shows “Windows protected your PC”, click More info → Run anyway. Then click Yes when Windows asks for permission.

  3. Follow the installer

    Keep the default options and click Install, then Finish. PhylaxNet opens on its own.

  4. Install Npcap when asked

    On first run the app opens npcap.com. Download Npcap, install it with the default options, then restart PhylaxNet. This is what lets it see devices on your network.

  5. Sign in

    Use the same email and password as this website. Your trial starts straight away. Have a license key? Go to Settings → Account & License, paste it in and press Activate.

  6. Name your devices

    The setup guide lists everything it found. Mark the devices you know as Trusted — PhylaxNet watches for the ones you don’t. Turn on Always-on protection in Settings so it keeps running after a restart.

If something goes wrong

No devices show up

Npcap isn’t installed or the app wasn’t restarted afterwards. Install it from npcap.com with the default options and restart PhylaxNet. Check the PC is on the main network, not a guest Wi-Fi.

The website says “Waiting for your agent”

In the app open Settings → Website Sync. It should say “Synced”. If it says “Sign-in needed”, sign out of the app and in again.

How do I update?

PhylaxNet updates itself. Each update is checked against our signature before it installs. You can also download the latest installer here and run it over the top.

How do I uninstall?

Windows Settings → Apps → Installed apps → PhylaxNet → Uninstall. Your account and history on the website stay until you delete them.
