Access Control Systems

Access control systems help organizations control who can enter specific areas, when they can enter, and under what conditions. Gallagher’s integrated solutions bring together readers, controllers, and security software to help small businesses, enterprise organizations, and critical infrastructure sites improve security, support compliance, and manage access at scale.

What is Access Control?

Access control sits at the intersection of physical security, regulatory pressure, and operational efficiency. The right system does more than lock and unlock. It's a source of business insight, shaping how your organization moves, decides, and grows.

With Gallagher Security’s access control systems you can:

  • Manage entry points in real time, from a single door to thousands across multiple sites.
  • Track personnel movement and access activity with detailed reporting.
  • Meet industry-specific regulations without manual workarounds.
  • Connect access control with your alarms, surveillance, and building management systems so they work as one.

Gallagher's solutions scale with you across a single site or a global operation, unlocking efficiency, insight, and value most security systems never reach. Because protecting your people and assets is where we start, not where we stop.

    Gallagher Controllers act as the central hub, securely processing access requests, managing data, and communicating with connected systems. Strong authentication and encryption between the controller and Gallagher system ensure the highest level of cybersecurity.
  • Software Management
    Assign roles, set access schedules, and monitor activity through our centralized platform, Command Centre, that offers customizable dashboards and detailed reporting.
  • System Integration
    Gallagher’s integration capabilities connect your security and operational systems into a single platform. Connect everything from building systems (e.g., lighting, HVAC), Video Management, and elevators to wireless access control and vehicle access control.
  • Real-Time Monitoring
    Receive instant alerts for unauthorized attempts, emergencies, or security breaches to enable immediate action.

Frequently Asked Questions (FAQs)

  • What is an access control system?
    An access control system manages and monitors who can enter or exit a building, site, or zone. Instead of relying on physical keys, it uses credentials, such as cards, mobile devices, or biometrics, verified by readers and controllers to make real-time access decisions. A software layer gives administrators the ability to configure permissions, monitor alarms, and generate reports across an entire site or organization.
  • What is the difference between cloud-based and on-premises access control?

    Cloud-based access control allows authorized administrators to manage site security through cloud technology, which can support easier remote management and faster deployment. On-premises access control is installed and operated within an organization's physical environment, giving businesses greater control over hardware, data, and system configuration.

  • What is the best access control system?
    The best access control system is the one that matches an organization's specific security requirements, scale, and risk profile, rather than a single one-size-fits-all product. Consider the number of doors and sites, the level of security needed, integration with existing infrastructure such as video or building management systems, and whether the business needs on-premises control, cloud-based flexibility, or a hybrid set-up. Gallagher Security offers a range of solutions spanning small business, enterprise, and high-security deployments, so organizations can select the level of functionality and compliance that fits their environment.
  • How does a commercial access control system differ from a traditional lock-and-key building security setup?
    Unlike static physical keys that provide unmonitored access and require costly re-keying when lost, a commercial access control system delivers centralized digital management, real-time audit trails, and instant credential revocations. Replacing mechanical locks with door readers, mobile credentials, and intelligent controllers, gives organizations visibility over who enters specific zones, lets them enforce automated access schedules, and integrates physical security directly with site operations.
  • Is Gallagher’s access control solution compliant with government security standards?
    Yes, Gallagher’s access control solution is compliant with government security standards. Gallagher Security has a proven history and global reputation for delivering access control solutions that meet the world’s most stringent government security standards. Our solutions comply with local government standards including FIPS, NPSA, and Class 5, as well as other global standards including ISO27001 and SOC 2. 
  • How do modern keyless access control systems work?
    Modern keyless access control systems replace physical keys with digital credentials such as smart cards, mobile credentials, or biometrics, that are read by a door reader and verified by a controller before granting access. Because credentials can be issued, updated, or revoked remotely, keyless systems give administrators real-time visibility and control without the security gaps or costs associated with rekeying physical locks.
  • How much does an access control system cost?
    The cost of an access control system depends on the number of doors, sites, users, credentials, integrations, compliance needs, and the level of security required. A small business may need a simple mobile-based system, while an enterprise or critical infrastructure site may require a larger solution with advanced reporting, monitoring, and integration capabilities.
  • Can access permissions be managed centrally across multiple sites in different countries?
    Yes. Gallagher's Command Centre supports multi-site deployments from a single management interface, allowing administrators to assign, modify, and revoke access permissions across geographically distributed sites without requiring separate systems at each location. A single credential can grant a cardholder access across multiple sites globally, with role-based operator permissions controlling what each regional administrator can view or action within the platform.
  • How does Gallagher integrate with building management systems?

    Gallagher integrates with building management systems using the BACnet protocol, a global standard for building automation. As part of an integrated security system, BACnet enables seamless communication between Gallagher’s Command Centre and various building systems like HVAC, lighting, and fire control. By integrating with business management systems, businesses can streamline operations, save costs, and enhance energy efficiency.

  • What types of access control systems does Gallagher offer?
    Gallagher offers access control solutions for small businesses, enterprise organizations, and high-security sites. This includes mobile-based cloud security for smaller or multi-site businesses, Command Centre for enterprise access control, and High Security solutions for critical infrastructure and sensitive environments.
