Strengthened security for assets

Each keyholder only has access to the areas for which he/she has a responsibility. The restriction on access linked to the key makes those working in any area more conscious of security, and significantly reduces the risk of theft or damage.

Increased staff security

Managing the flow of people using a masterkey system prevents unauthorized movement or access to at-risk spaces within a site. Access to hazardous areas is only permitted for authorized persons. Security personnel with a pass can access the site of an incident more quickly.
