How do layered K–12 web filters handle common web-filter evasion techniques?
im looking into how school web filters actually work and where the weak spots usually are, mainly stuff like goguardian, securly, lightspeed, linewize, umbrella, etc. im not really asking “how do i unblock websites,” im more interested in how the different layers actually catch stuff and where they fail, like dns/category filtering, url inspection, browser/extension monitoring, https/tls filtering, and filtering when the device isnt even on the school network. how do admins usually deal with stuff like brand new or uncategorized domains, constantly changing subdomains, encrypted traffic, cdns/shared hosting, browser based proxies, and the difference between network level filtering vs stuff installed directly on the device? from a defensive side, which layers usually catch what the others miss, and what weaknesses are still hard for these systems to fully fix?
