Ofcom has published regulatory guidance under the Online Safety Act requiring platforms to implement age verification or age assurance where they host content harmful to children, including pornographic material and content promoting self-harm, eating disorders or suicide. The measures, which form part of illegal harms and child safety duties coming into force in 2025, mandate that services either prevent children from encountering harmful content through age checks or apply protective measures uniformly to all users. Ofcom has specified that highly effective age verification must be used for pornography sites, with companies given three months to comply once the guidance is finalised, and has indicated it will maintain a public compliance register.
Age assurance establishes eligibility but does not inspect the substance of interaction. A child verified as underage and shown a safer feed can still receive direct messages containing grooming scripts, sextortion threats or AI-generated abuse imagery from an attacker operating within the same age-gated environment. Real-time content monitoring at the message layer, such as Guardii's detection modules for grooming, sextortion and child sexual abuse material, flags the harmful exchange itself before it escalates, whether the sender has passed age verification or not. The regulatory framework sets a perimeter; threat-pattern recognition defends the interior.
