Can School WiFi See What You Do?

School networks have more monitoring capability than home routers. Here's exactly what they can see — and it's more than most students realise.

Updated 2026

  1. 1

    Domain-level traffic

    The school's network logs every domain your device connects to — whether you're in incognito or not. They can see reddit.com, instagram.com, gaming sites, etc.

  2. 2

    Content filtering and blocking

    Most schools use DNS filtering or proxy systems (like Cisco Umbrella or Smoothwall) that actively block certain categories and log attempts to access them.

  3. 3

    SSL inspection (HTTPS)

    Some schools use SSL inspection, which decrypts and re-encrypts HTTPS traffic. This means they can potentially see the full page URLs and content — not just the domain. Your browser may show a warning or a different certificate.

  4. 4

    Device vs network monitoring

    If the device is school-owned, they may also have MDM (Mobile Device Management) software installed that monitors activity beyond just the network.

  5. 5

    What a VPN does on school WiFi

    A VPN hides your traffic from the network's DNS logs and content filter — but the school may be able to detect and block VPN connections. Some schools explicitly prohibit VPN use.

Frequently Asked Questions

Can the school see my activity on my personal phone?
Only the network-level traffic (domains visited) while connected to the school WiFi. They can't access anything stored on your device unless they installed an MDM profile.
Can teachers see your screen through school WiFi?
Not through WiFi alone. Screen monitoring requires software installed on the device, not just network access.
