Note.
- Deep SSL Inspection should be used for Image Analysis
- Select a strictness value between 0 and 100. The higher the image score, the more chance of the image being explicit. The challenge with this setting is that if it is set too high, it will block legitimate images. To set it too low, it will allow explicit images through. If the image score is above this setting, the Rating Error Action is taken.
- Apply a AV profile with legacy mode enabled.
