The device provided to your son or daughter by Defiance City Schools is filtered both on and off campus with Relay Cloud Filter by LightSpeed Systems. That being said no Internet filter is foolproof; there will always be questionable and age inappropriate websites that are not stopped by the filter. Internet filters do not scan or view the material of individual web sites but rather rely on a website classification system. There are websites that do not properly classify themselves as mature and therefore Internet filters do not know to block them. In addition a sufficiently motivated child can find additional methods to circumvent an Internet filter including web proxy filters and virtual private networks (VPN). Please use common sense when your son or daughter is using their district issued Chromebook; there is no substitute for attentive adult supervision.
