Our approach

Vysiion takes a consultative approach to all physical security and surveillance deployments, interpreting or developing a set of Site Specific Operational Requirements (SSOR), in order to guarantee an efficient, successfully deployment. This begins with a comprehensive onsite survey, to ensure the specifics of the existing OT security infrastructure have been fully understood. 

The specifics of each survey will be bespoke to each site, but will typically encompass the following categories: 

  • Beyond the perimeter 
  • Perimeter 
  • Within the site 
  • Security 
  • Assets 

Once these areas have been thoroughly assessed and project specifications agreed upon, suitable designs can then be developed, drawing on Vysiion’s well-established network of trusted suppliers and solutions, including CPNI accreditation, when required. 

Based on these findings, a fully integrated service wrap will be proposed and agreed upon, in order to fulfil all current requirements, while leaving plenty of scope for future agility and scalability.
