Security teams on the ground across the Denver metro

Through 28 September, 2026, Denver PD recorded 20,671 property crimes year to date, a 6.4% decline from 2025 and 20.6% below the three-year average . The decline is meaningful, but 20,000 incidents in nine months means these incidents are still common across the metro. Kastle has provided security services for over 50 years, protecting more than 10,000 properties and 60,000+ businesses across the United States and Australia. Denver coverage extends from the central business district to Aurora, Lakewood, Westminster, Arvada, and surrounding communities.

One partner, every stage

Designed, installed, monitored, and maintained by one team

Denver's commercial market includes office towers, multi-tenant buildings, healthcare facilities, retail locations, and mixed-use developments across the metro and surrounding areas like Aurora, Lakewood, and Arvada. Each property type has different access requirements, compliance obligations, and patterns of daily foot traffic. Managing access control across that range demands more than hardware at the door. It requires a single program responsible for the initial site assessment, physical installation, around-the-clock monitoring, and ongoing maintenance, with one point of accountability from the first walkthrough through year ten and beyond.

Site assessment and system architecture for access control in Denver

Denver recorded 30,682 property crimes in 2025, more than any other jurisdiction in Colorado. That is the threat environment Denver facility managers are defending against. A managed access control deployment begins with a physical walkthrough of the building, identification of every controlled entry point, and a risk-based assessment that accounts for the property's use, tenant mix, and applicable compliance requirements. The design that follows specifies readers, credentials, controllers, and integration points before hardware is ordered.

  • Physical walkthrough of every door, garage, elevator, and stairwell.

  • Credential strategy matched to your building's tenant mix and turnover.

  • System architecture documented and reviewed before hardware is ordered.

Built and run by one team

What every stage of a Denver access control project covers

  • Consult: A security architect assesses your Denver property, maps every entry point, and identifies the access requirements for your building type and tenant mix.
  • Design: The team specifies readers, credentials, controllers, and integration points based on the assessment. The system architecture is documented and reviewed before any hardware is ordered.
  • Install: Kastle-employed technicians install and commission the system door by door, with a phased plan that keeps the building protected throughout the transition.
  • Monitor and maintain: The system is monitored around the clock from a dedicated operations center. Firmware updates, hardware maintenance, and credential reviews happen on a scheduled cycle with a single point of contact for any issue.
