DSI delivers custom security engagements for clients and partners worldwide. These engagements are tailored to fit the specific needs of enterprises and organizations confronted with threats to personnel and assets.

Industry PetroChem 500All engagements begin with a vulnerability analysis, a process of identifying, quantifying, and prioritizing the vulnerabilities in a system. In general, a vulnerability analysis serves to categorize key assets and drive the risk management process.

Whether a high rise in an urban environment or a manufacturing plant in a rural area, each site comes with a unique set of physical security challenges and requirements. Physical security controls are essential to protecting facilities, sensitive information, and personnel from natural and human threats.

Industrie Manufacturing 500Our teams perform an on-site assessment of selected facilities and evaluates your organization’s physical security, and with your experts, evaluate the perimeter, access control systems, video surveillance, insider threat, and other areas essential to an effective physical security program. DSI’s teams draw from extensive backgrounds in military/paramilitary operations, security auditing, and emergency response.

Our professional experience includes threat intelligence, policy development, and tactical operations planning, training, and response. This allows our team the ability pinpoint gaps in physical security controls and recommend both tactical and strategic improvements that support your business goals in a cost effective manner.

We provide vulnerability assessments as a stand-alone service and as the front-end to longer term engagements requiring detailed budgets and proposals.
