Did Trump cut cyber security?

Did Trump cut cyber security refers to US policy, and yes during both the first Trump administration and second administration there were significant changes and cuts to cyber security funding and agencies that impacted US and global cyber security including Australia. In 2018, the Trump administration created CISA, the Cybersecurity and Infrastructure Security Agency, which strengthened federal cyber security, but also cut the White House cybersecurity coordinator position. In 2020, budget proposals sought cuts to some cyber programs but Congress restored many. More significantly, in early 2025 during second Trump administration, the administration implemented major cuts and restructuring affecting cyber security. According to reports, the administration cut CISA staffing by about 30%, reduced funding for election security, disbanded or downsized advisory committees like the Cyber Safety Review Board, and paused some grants for state and local cyber security. The administration also proposed cuts to State Department cyber diplomacy and reduced funding for NIST cyber programs. These cuts raised concerns among US cyber professionals that US cyber defence would weaken against Russian, Chinese and ransomware threats. For Australia, US cuts affect Five Eyes intelligence sharing and joint cyber operations, but Australian cyber funding increased under its own Cyber Security Strategy 2023-2030 with $2.3B investment, so Australia is not directly cutting. So while Trump both created CISA and later cut parts of cyber security bureaucracy, the net effect in 2025 was reduction in federal cyber workforce and grants.
