CREST is a UK academic "think tank", with substantial funding from the security & intelligence agencies and only id'd yesterday. CREST explains itself:
The Centre for Research and Evidence on Security Threats (CREST) is a national hub for understanding, countering and mitigating security threats. CREST brings together the UK’s foremost expertise in understanding the psychological and social drivers of the threat, the skills and technologies that enable its effective investigation, and the protective security measures that help counter the threat in the first place. It does so within a context of significant stakeholder and international researcher engagement, and with a clear plan for sustained and long-term growth.
