From 3 April, the EU will become the only region worldwide without legal certainty allowing technology companies to detect child sexual abuse material online, prompting urgent warnings from child protection experts and global tech organisations. A coalition of 246 civil society groups and major industry players has condemned lawmakers for failing to extend the temporary legal framework that permitted privacy‑preserving detection tools, leaving companies unsure whether safeguarding systems remain lawful. With the EU already hosting the highest concentration of known child sexual abuse material - 62% of confirmed webpages in 2024 - experts warn the situation will worsen, reducing detections, hampering investigations, and emboldening offenders. As the EU’s proposed permanent legislation remains deadlocked, industry leaders and protection advocates stress that immediate action is essential to prevent increased harm to children across Europe and beyond.
