Edward Nicole

Founder & Managing Director

After serving as a Reconnaissance Officer in the British Army, Edward Nicole worked for two leading international security and intelligence companies.

Frustrated at a lack of professionalism in the industry and a culture of backhanders and kickbacks, he founded Marengo with the backing of his former employers. Edward wanted to show that security companies can be honest brokers and provide the level of service that discerning clients require.

​​Marengo offers a service that combines expert advice with individual client needs. It delivers comprehensive, thoughtful solutions to complex security and intelligence problems. This means clients can enjoy a better, more reliable, more secure lifestyle.

Edward is a Certified Security Management Professional who advises some of the world’s most high-profile family offices, law firms, conglomerates, and sports companies.

Mathew Davis

Operations Specialist & Security Advisor

Matt brings extensive experience and deep strategic insight to Marengo. With over 30 years of distinguished service in the Metropolitan Police, his experience in covert policing, counterterrorism, and high-level armed security strengthens Marengo’s capabilities in addressing complex security challenges. His collaborative work with UK Special Forces and the MoD, particularly in combating organised crime and terrorism, means he is well-positioned to advise HNWs, family offices, and corporates.

Matt played a key role in establishing the Counterterrorism Operations Centre (CTOC) and is a specialist in command and control. He planned the security for numerous high-profile London events, including protection of the Royal Family. He commanded many of the recent armed policing operations in London including the Platinum Jubilee, President Biden’s state visit, the late Duke of Edinburgh’s funeral, and the largest ever: the funeral of Queen Elizabeth II.

Specialisms in covert surveillance, hijack, siege, hostage rescue, close target reconnaissance, and advanced driving make him an asset to Marengo and its clients.
