Close protection

We provide industry-leading close protection services for VIPs, business executives, celebrities, and high-profile individuals.

Our experienced close protection officers (CPOs) and security drivers are smart, adaptable, and discreet. Drawn from police, military, or special forces backgrounds, they receive regular training to provide effective, unobtrusive, and inconspicuous protection for our clients.


Residential security

Our security guards oversee the protection of private properties, commercial offices, and development sites.

From urban centres to sizable country estates, our professionals customise their strategies to ensure the safety of you, your organisation, and your property.

Service Travel Security

Travel security & travel risk reports

Our services encompass itinerary management, physical security protection, and executive travel support. We use intelligence-led approaches, incorporating embedded security professionals, GPS tracking, and meticulous medical and logistical planning.

We provide country- and region-specific security information such as advised GPs, routes, providers, and localised best practice personal security guidance.

Service Event Security

Event security

Securing premises and individuals during events requires specialised expertise. We offer a professional, seamless, and efficient event security service.

Our team provides comprehensive support throughout, including planning, risk assessment, event setup, asset protection, and close protection for high-profile individuals at the event.

Services Security Reviews

Security reviews

We independently review, design, and implement security systems for residential houses, corporate offices, and commercial sites to help create a secure environment for you, your family, or your organisation.

We help to cut costs of excessive security equipment peddled by equipment providers, and ensure that security infrastructure is proportional, tasteful, and functional.

Services Contingency Planning

Security management

Marengo provides clients with comprehensive contingency and response planning services. We begin by conducting a thorough assessment of all relevant threats to which our clients may be exposed. This includes evaluating the likelihood and potential impact of each risk.

Once identified, we prioritise these risks based on their significance.

We implement additional proportional security measures tailored to each client’s specific needs. We issue guidance on preparation planning and response procedures, ensuring that our clients are well-equipped to handle unforeseen circumstances.

We aim to arm clients with the necessary tools and strategies to minimise disruption, protect assets, and maintain operational continuity following an incident.

Service Penetration Security Testing

Penetration testing

We use a range of techniques to conduct simulated attacks on offices, commercial sites, and private properties. We expose potential vulnerabilities in the existing security plan using strategies commonly used by organised criminal gangs and threat actors. These include hostile reconnaissance, RFID cloning, lockpicking, climbing, and social engineering.

Following an initial reconnaissance phase, we develop a plan to enter the site, comprehensively stress-testing the existing security.

Techniques used, courses of action taken, security vulnerabilities, and recommended additional security measures are then outlined in a written report or oral brief to the client.
