Enterprise Security

Enterprise access control is the foundation of an enterprise security system. It answers three questions at scale: who is allowed where, when are they allowed there, and can you prove it. The difficulty at enterprise level is answering those questions consistently across dozens or hundreds of sites and thousands of credential holders.

Gallagher’s enterprise access control manages credentials, permissions, and policies centrally through Command Centre. Change a policy once and it propagates across every site. Revoke a credential and it is revoked everywhere. When an auditor asks for an access-history report spanning multiple facilities, it comes from a single data source. Access control for multiple sites is handled natively, so an organization defines its enterprise-wide policies once and layers site-specific rules on top where local requirements differ.

Mobile credentials enable smartphone-based access for organizations moving toward a cardless credential strategy, reducing card management overhead and simplifying provisioning at scale.

Intruder detection is the response layer that access and perimeter events feed into. Because it runs on the same platform, an alarm arrives with the context of what happened around it.

From Command Centre, operators arm and disarm intruder alarm zones across every site, schedule when each zone is active, and route alerts to a monitoring station so the right people can respond. Because intruder, access, and perimeter events share one view, an operator can follow the whole sequence of an incident as it develops.

Perimeter security is the first layer of a defensive security model. For enterprise environments, it means protecting the physical boundary of every site, from fence lines and vehicle gates to building envelopes and restricted outdoor areas. A perimeter security system both deters intrusion and detects it early, before an intruder reaches the building.

Gallagher’s perimeter solutions combine monitored security fence hardware with detection sensors that identify and locate breach attempts along the boundary. When a perimeter alarm triggers, it carries location data and can start an automated workflow within seconds, notifying the nearest response team, recording associated video, locking nearby access points, and creating an incident record. That whole chain is captured in the audit trail. For sites with high-security requirements, these solutions support the layered detection models that critical infrastructure, government, and defense environments demand.

A visitor management system is a core security and compliance layer. At enterprise scale, it controls how every visitor and contractor enters the estate, captures who was on site and when, and removes access the moment a visit ends. An enterprise visitor management gives security teams the same visibility over temporary guests as they have over permanent staff.

The essential features that matter for enterprise visitor management are pre-registration of expected visitors, customizable sign-in workflows, automatic host notification when a guest arrives, and QR or biometric check-in for fast, accurate identification. Through a secure integration with Command Centre, our visitor management system, powered by Kenai, issues the right credential automatically, whether that is a QR code, a mobile credential, or a physical badge, and revokes it the moment a visit ends. Induction and qualification requirements can be enforced as access prerequisites, so only people who meet site safety rules are admitted. Zone-based access and visitor-type access groups mean a contractor, a job candidate, and a maintenance technician each get exactly the access their visit calls for, and nothing more.

When you choose a visitor management system for an enterprise estate, the test is whether it shares the same platform, audit trail, and policy engine as the rest of your security.

At enterprise scale, security does not operate in isolation. It connects to HR systems, building management, video surveillance, identity platforms, and operational technology. Gallagher’s integration capabilities bring these systems together within Command Centre, creating a single operating platform that reduces the number of interfaces a security team manages and improves the quality of data available for decisions.

The real value comes from workflows that span those systems. When an employee’s status changes in the HR system, their access permissions update automatically. When a building management system flags an after-hours HVAC activation, Command Centre surfaces the matching access event for investigation. And a video management system links its alarm footage straight to the incident record.

Typical integrations connect the systems an enterprise already runs. Video management supports alarm verification and investigation, HR and identity platforms automate credential provisioning, and building management coordinates HVAC and lighting. Elevator control restricts floor-level access, intercom systems verify entry, vehicle access uses LPR and RFID for gate automation, and biometric readers authenticate high-security zones.
