Philip Grindell
Spear’s Review
After Philip Grindell retired from the police in 2019, having led the effort to protect MPs after the death of Jo Cox, he set up Defuse to safeguard high-profile individuals and corporations from physical, reputational and psychological harm.
‘Our goal, our purpose, is to help clients feel safer,’ Grindell tells Spear’s. ‘Anybody can make somebody feel safe ... but the real skill is in ensuring that security.’
Grindell’s service combines protective intelligence, forensic psychology and rigorous data analysis in order to eliminate the anxiety caused by intimidation and threats, whether it is stalking and harassment or data breaches. Strategies are tailored to each client based on their individual circumstances. ‘What we do, what we focus very deeply on, is solving the problem rather than putting sticky plasters on,’ he says. ‘Our goal is to actually instigate services and processes so that they have one less thing to worry about.’
Adviser Profile
When ultra-high-net-worth families face serious threats, Philip Grindell gets the call others can’t handle.
While most security firms deploy bodyguards and technology, Grindell stops threats at their source – before they escalate, cause damage and define clients’ lives by fear.
As founder of Defuse Global, he leads a hand-picked team of globally recognised experts who solve what others miss entirely. Obsessive stalkers who’ve studied clients for months. Coordinated harassment campaigns targeting multiple family members. The Privacy Package – his signature solution – mitigates the methodology used by fixated people, activists and criminals to target prominent families.
His track record speaks volumes. Hand-picked to lead Parliament’s response after Jo Cox’s assassination, Grindell’s team prevented a second MP murder – identifying and stopping a terrorist plot in 2017. That same methodology, delivered through his specialist team, now protects prominent families worldwide.
Trained by Dr Robert Fein, architect of the US Secret Service threat assessment model, Grindell applies behavioural analysis techniques no other consultant possesses. He’s among fewer than 300 Chartered Security Professionals globally, leading experts in understanding complex threat patterns.
A well-renowned commentator on targeted attacks against public figures, Grindell regularly appears in national media discussing the evolving threat landscape facing prominent individuals.
Family office directors describe identical outcomes: hypervigilance ends, everyday life resumes, and principals focus on business rather than survival. One noted, ‘Philip’s team transformed our lives from concern to confident living.’
Author of Personal Threat Management, Grindell has quietly become the consultant other advisers call when conventional security isn’t enough.
