EU Cyber Defense Partly Effective, Auditors Report

The European Court of Auditors (ECA) released Special Report 19/2026, assessing the EU's cybersecurity cooperation framework for 2022-2025. The audit found that while progress has been made, the framework only partially facilitates detection of and response to serious cyber incidents. Key issues include limited information sharing between member states, underreporting of incidents, and significant implementation delays, particularly of the NIS2 directive, with only two member states meeting the October 2024 deadline. Cross-border incident reporting remains sparse, with only 14 reported in 2025 and none classified as 'large-scale' since 2016. The Collins Aerospace ransomware attack highlighted systemic failures, as it was not treated as significant. The ECA also criticized the underutilization of the EU Cyber Reserve, non-operational cyber shield hubs, and duplication of efforts in the Commission's cyber situational centre. Five recommendations were issued, with target dates from 2026 to 2028.

  • EU member states reported 1,276 incidents to ENISA in 2024, while ENISA identified ~4,800 from public sources.
  • Only 14 significant cross-border incidents were reported by seven member states in 2025; no incidents have been classified as 'large-scale' since 2016.
  • Only two member states met the NIS2 transposition deadline of October 2024.

Google's ad tech remedies arrive as platform battle moves to AI

Google has been ordered by a federal judge to implement behavioral remedies to its ad tech business, avoiding a forced divestiture of its ad exchange (AdX) and publisher ad server (DoubleClick for Publishers). The six-year regime requires Google to integrate more closely with Prebid, allow AdX to bid on competing ad servers, facilitate publisher data portability, and limit preferential treatment of its own ad tech. This comes as the antitrust focus shifts toward AI-powered advertising platforms. The article is paywalled and provides limited substantive detail beyond the headline and initial paragraphs.

  • Judge Leonie Brinkema issued a remedies opinion in the Google ad tech antitrust case.
  • Google will retain AdX and DoubleClick for Publishers under a six-year behavioral regime.
  • Google must integrate its technology more closely with Prebid and allow AdX to bid into competing publisher ad servers.

Amazon Blocks Meta's Muse AI Agent from Shopping

Amazon has blocked Meta's AI shopping agent, Muse, from accessing Amazon.com, citing unauthorized access, lack of transparency, and violations of its terms of service, privacy, and security. Muse, launched in September 2026, quickly gained over 900,000 downloads but failed to identify itself as automated and bypassed sponsored products, reducing Amazon's ad revenue. This move is part of Amazon's broader crackdown on AI agents from Perplexity, Google, and OpenAI. Meanwhile, Shopify is partnering with Meta to integrate Muse with Shop Pay, and Meta plans to connect Muse with Meta Business. The conflict underscores tensions over AI agents' control of customer interfaces and data, with Amazon's own 'Buy for Me' agent openly identifying itself and allowing opt-outs, setting a precedent for AI agent behavior in e-commerce.

  • Amazon blocked Meta's AI agent Muse from its platform due to unauthorized access and lack of transparency.
  • Muse has over 900,000 downloads in six days and can autonomously make purchases without identifying as a bot.
  • Amazon cites privacy/security concerns and bypassing of advertising as reasons for the block.
