LenelS2 OnGuard

LenelS2 OnGuard uses a scalable client-server architecture designed for enterprise access control and security management environments. The platform supports centralized and distributed deployments. Controllers, communication services and operator workstations can run across multiple buildings, sites and locations. OnGuard supports high-availability architectures using redundant infrastructure and supported failover configurations. Availability and recovery capabilities depend on the installed software version, licensed features and underlying server and database infrastructure. Traditional OnGuard is primarily deployed on-premises. Cloud-hosted and hybrid options may be available through supported infrastructure and connected services. OnGuard Cloud is offered as a separate cloud-hosted solution. Enterprise-wide management capabilities should not automatically be interpreted as native federation between independent OnGuard installations. Such functionality requires verification against the relevant software edition and architecture.
