National Protective Security Authority (NPSA)

---

NPSA is the UK's national technical authority (NTA) dedicated to enhancing physical security, countering terrorism, and mitigating hostile state activities to ensure our country remains safe. We primarily serve the UK's critical national infrastructure (CNI), government, and other high-risk, sensitive sectors. Our expertise also extends to advising on other nationally important assets or events, including high-profile iconic targets, where the consequences of damage would be similarly severe.
