UK Online Safety Act Enforcement Begins with Ofcom Issuing First Information Notices

UK communications regulator Ofcom has issued its first formal information notices to social media companies under the Online Safety Act, requiring platforms to provide detailed accounts of their child protection systems and illegal content moderation processes. The notices, which carry statutory force, mark the beginning of active enforcement of the legislation that came fully into effect in March 2026, with platforms facing fines of up to ten percent of global revenue for non-compliance.

Compliance frameworks mandate that platforms demonstrate effective harm-reduction systems, but the architecture matters as much as the obligation. Detection engines that identify grooming, sextortion and CSAM distribution in real time—including AI-generated abuse material—answer the regulatory requirement with a mechanism that intervenes at the point of contact rather than after harm has occurred. Guardii, a Meta Business Partner and world-leading online-safety AI, enables organisations to meet statutory duties through pattern recognition that flags escalation and coercion without building a keyword surveillance regime, closing the gap between regulatory expectation and operational capacity.
