The lesson from this incident
Full lessonMiljödata's failure to adequately vet new software before deployment and the absence of real-time monitoring created the conditions for a large-scale breach affecting 2.2 million individuals, exposing highly sensitive data including national identity numbers and health information. This case illustrates that security controls must be proactive — not reactive — especially when handling special categories of personal data under GDPR. The regulator's finding under GDPR Article 32(1) underscores that 'appropriate technical measures' is a legal obligation, not a best-practice suggestion. IT providers handling sensitive citizen data at scale carry an amplified responsibility, as a single failure in their environment can cascade across millions of people.
