UK Online Safety Act: Ofcom publishes final illegal content enforcement guidance

The UK communications regulator Ofcom has published final guidance on illegal content duties under the Online Safety Act, clarifying expectations for platforms to prevent child sexual exploitation and abuse material, including grooming and solicitation, from appearing in user-generated content and direct messages. The guidance, effective immediately for Category 1 services, requires risk assessments covering direct messaging features, proactive monitoring where technically feasible and proportionate, and systems to identify accounts and content associated with child sexual abuse. Ofcom has indicated it will assess compliance through transparency reports and may impose fines or service restrictions for persistent failures.

Direct-message environments present the greatest detection challenge because abuse occurs in private channels where traditional content moderation has limited reach and encryption often prevents platform-level scanning. Guardii addresses the operational gap by deploying real-time pattern recognition across Instagram, Snapchat, Discord, Roblox and other messaging services, identifying grooming conversation structures, age-inappropriate contact, and sextortion tactics as they develop, and escalating serious threats to parents, schools, or law enforcement before harm is completed. The system reports the shape and severity of a conversation rather than its content, satisfying the proactive detection expectation Ofcom has set while respecting privacy constraints that make message-level surveillance impractical at scale.
