YouTube Channel Blocking

YouTube Channel Blocking

KyberGate goes beyond simple YouTube allow/block by letting you control access at the individual channel level. Block specific channels that are inappropriate while keeping YouTube available for educational content.

Before You Begin

  • You need Admin or Policy Manager role
  • YouTube must be allowed in your filtering policy (if YouTube is fully blocked, channel-level controls don't apply)
  • Devices must be routing through the KyberGate proxy

How YouTube Channel Blocking Works

KyberGate inspects YouTube traffic at the URL level, identifying which channel a video belongs to. When a student tries to watch a video from a blocked channel, they see the KyberGate block page instead of the video.

This works for:

  • Direct channel page visits (youtube.com/c/ChannelName)
  • Individual video pages from blocked channels
  • Embedded videos from blocked channels
  • YouTube Shorts from blocked channels

Blocking a YouTube Channel

  1. Navigate to Settings → Web Filtering → YouTube Controls
  2. Click "+ Block Channel"
  3. Enter the channel in one of these formats:
    • Channel URL: https://youtube.com/c/ChannelName
    • Channel ID: UCxxxxxxxxxxxxxxxx
    • Channel name: Search by name and select from results
  4. Add an optional reason (e.g., "Inappropriate gaming content")
  5. Choose which policies this block applies to
  6. Click "Block Channel"

Creating a Channel Allow List

For maximum control, you can flip YouTube to Allow List mode:

  1. Go to Settings → Web Filtering → YouTube Controls
  2. Toggle "Allow List Mode" on
  3. Only channels you explicitly add to the Allow List will be accessible
  4. All other YouTube channels will be blocked

This is ideal for:

  • Elementary school environments
  • Specific classroom assignments using curated video content
  • Standardized testing periods

Managing Blocked Channels

  • View all blocked channels: See the full list with who blocked them and when
  • Search: Find channels by name in your blocked list
  • Bulk import: Upload a CSV of channel URLs to block many at once
  • Temporary unblock: Disable a block without deleting it

Monitoring YouTube Activity

KyberGate logs all YouTube activity for managed devices:

  • Which channels students visit
  • Which videos they watch (title and duration)
  • Search queries on YouTube
  • Attempted access to blocked channels

View this data in Reports → Activity Logs filtered by "YouTube."

Troubleshooting

  • Channel block not working? Verify the channel URL/ID is correct. Some channels have multiple URLs — try the channel ID format for reliability
  • Videos still playing? If the video is embedded on another site, ensure your proxy is inspecting that domain (not in the bypass list)
  • Too many channels to manage? Consider using Allow List mode instead of blocking individually

Tips

  • Combine with Restricted Mode: Use SafeSearch enforcement for YouTube Restricted Mode alongside channel blocking for layered protection
  • Teacher requests: When teachers need specific channels, add them to the Allow List rather than removing blocks
  • Student reports: Check the Activity Logs to find channels students are accessing that should be blocked
