Shires Crichton

Spear’s Review

Shires Crichton serves as CEO of Amba Defence, a security and intelligence organisation that looks after high-profile individuals, ultra-high-net-worth clients and corporate entities.

Amba helps clients in four ways: by mitigating risk and managing strategy as a consultancy service; by using technology to help manage risks; by working within a family office or family unit setting to deliver their residential security programme; and by monitoring threats via a 24/7 control centre.

It is with the latter that Amba has ‘plugged the gap’ in the security and intelligence market to be a ‘real 24-hour business’. Through this model, Crichton says, they are able to provide ‘real, current, live advice’ to maximise the impact of a threat response. 

Adviser Profile 

With over 25 years of experience devising sophisticated security strategies for ultra-high-net-worth individuals, global corporations and foreign governments, Shires Crichton leads Amba Defence Global with precision and vision. Under his leadership, Amba is now one of the UK’s foremost security and surveillance firms, with a growing international footprint.

‘As security continues to be top of mind across the world, ADG remains at the forefront of security delivery. Technology and AI are key in keeping one step ahead in today’s ever dangerous world,’ commented Crichton.

In the 18 months since the formation of Modicum Consulting – a specialised advisory arm dedicated exclusively to the UHNW sector – the firm continues to deliver bespoke security strategies and risk assessments to private clients, royal households, family offices and top legal firms. Working closely with its sister company, Amba Defence Global, Modicum draws on an elite in-house team of security specialists to offer cohesive, high-level protection solutions.

‘Our ethos is about loyalty and privacy to every single client, large or small. We have a complete commitment to every piece of work we execute,’ said Crichton. ‘Our point of difference comes from an integrated 360-degree security approach based on the initial conversation to understand the real requirement through implementation, monitoring and continued client support.’

When we look at the future, we see an ever-changing security landscape, with new technology developing rapidly and artificial intelligence making its mark on the industry. The team at Amba Defence and Modicum Consulting are involved in developing security solutions for tomorrow’s world, pre-empting change and preparing for what comes next.
