Clue launches new report on tackling insider threats through intelligence-led prevention

Clue has released a new report exploring the growing risk of insider threats and how organisations can build intelligence-led capabilities to prevent them before harm is done.
As insider incidents grow in scale and severity – from data leaks and sabotage to ransomware and espionage – Insider Threat Assessment: The Case for Intelligence-Led Prevention highlights the urgent need for a proactive, joined-up approach to this rising security challenge.
In the report’s foreword, Matt Horne, Director of Intelligence & Investigations at Clue, writes:
“Insider threats are not merely technical anomalies – they are intelligence failures. Failing to anticipate, contextualise, and understand insider behaviour is a failure to see the full risk picture.”
Drawing on real-world case studies from policing, defence, and corporate security, the report reveals how traditional detection tools often miss key warning signs and how organisations can move beyond reactive response to strategic prevention.
The report explores:
- The evolving motivations behind insider behaviour—from ideology to coercion
- Critical case studies from national security and corporate environments
- A behavioural-led framework for risk detection and cross-functional response
- Why traditional tools like SIEMs are falling short
- How Clue enables integrated, intelligence-driven insider threat prevention
Insider threats are no longer fringe risks – they’re a mainstream security challenge impacting governments, businesses, and institutions alike. The report calls on organisations to rethink outdated approaches and embrace intelligence as a core function of insider risk management.
