What is Atrium
Atrium is an enterprise visitor management platform that digitizes the entire front desk workflow — from pre-registration and check-in to document signing, WLAN provisioning, and check-out. It replaces paper sign-in sheets, manually created guest WiFi accounts, and disconnected spreadsheets with a single integrated system.
What it does
- Pre-registration — Hosts schedule visits in advance. Visitors receive an email with a QR code and can review and sign required documents before arrival.
- Kiosk check-in — Visitors scan their QR code at a tablet in the lobby. The kiosk displays documents for acknowledgment, captures a digital signature, and issues time-bound WLAN credentials — all without receptionist involvement.
- Network access control — Guest WLAN accounts are provisioned automatically via RADIUS. When a visit ends or expires, active WiFi sessions are terminated on the firewall — not just the credentials, but the live connections.
- Real-time dashboard — A live view of everyone currently on site, filterable by status. Doubles as an evacuation list.
- Document management — Customizable document templates (NDAs, safety policies, data processing notices) with version tracking. Every signed document is archived as a tamper-evident PDF.
- Multi-site operation — Centralized management across locations, with per-site configuration for documents, kiosks, and network settings.
- CRM and calendar integration — Visitor records sync with your CRM. Meeting rooms are looked up and booked via Exchange or Google Calendar.
What it is not
Atrium focuses on the visitor lifecycle and guest network access. It does not manage physical access control (badge readers, turnstiles, door locks), corporate network infrastructure, or package deliveries.
System components
Atrium consists of three components that work together:
| Component | Purpose |
|---|---|
| Atrium Server | The core application. Handles visitor lifecycle, authentication, the admin dashboard, the kiosk UI, document management, notifications, and all integrations. This is what you interact with daily. |
| Atrium Agent | An optional on-premises component for network integration. Handles RADIUS authentication for guest WiFi and communicates with your firewall to terminate sessions. Deployed as a single Docker container on your local network. |
| Atrium Control Plane | Manages licensing, software updates, and feature configuration across all Atrium deployments. You don't interact with it directly — it works in the background. |
Most users only interact with the Atrium Server — specifically the admin dashboard (for managing visits, users, and settings) and the kiosk UI (for visitor self-service check-in).
Deployment options
Atrium runs the same code in two deployment modes:
- SaaS — We operate the infrastructure. You sign up, configure your tenant, and start managing visitors. The Atrium Agent can be deployed on your local network for WiFi integration.
- Self-hosted — You deploy the full Atrium stack on your own infrastructure as a Docker Compose stack. Same features, same code, full data sovereignty. See Self-Hosted Deployment for details.
Both modes connect to the Control Plane for licensing and updates. Self-hosted deployments operate autonomously if the connection is temporarily unavailable.
User roles
Atrium has three user roles with different levels of access:
| Role | What they can do |
|---|---|
| Tenant-Admin | Full access across all sites. Manages users, sites, identity provider configuration, and tenant-wide settings. |
| Site-Admin | Manages one or more assigned sites. Configures document templates, kiosk tablets, network settings, and handles visitor management for their sites. |
| Member | Invites visitors, views their own visitor history, and receives arrival notifications. Cannot access admin functions. |
Every authenticated user — regardless of role — can act as a host: invite visitors, receive check-in notifications, and view their own visitors' status.
