We serve as well the profit as the non-profit sector. The basis for our way of working is a personal approach, competitive pricing, integrity, and, last but not least, global expertise.Implementing and maintaining a security management system can be a time-consuming process. Certain aspects of the system might require external advice. From us, you may expect:

Customized approach: Our services will fit your organization’s requirements, mandate, capabilities, and limitations.

Competitive tariffs: In our quotations, we will specify and be transparent on how we come to our tariffs

Integrity: In security management, confidentiality is key. Confidential data from the customer must, under all circumstances, remain safe. Please find our privacy statement under terms & conditions

Expertise: Our experience reaches back to 1994. Before specializing in safety and security, William held senior positions by a variety of INGO and IO’s. As a delegate of the International Red Cross Movement for 12 years, Incident investigator and safety and security advisor on country, global and regional level, the expertise to assist and advise upon any security issue you may be confronted with is there.
