Segment networks
Separate tills, guests, staff, building systems, signage and management with explicit policies.

Security and monitoring for live site operations.
Security does not end at the firewall. a4o combines segmentation, secure access, central monitoring and clear response paths into an operation that detects and contains incidents.

Make security and monitoring visible
Security that fits the site
Control access
Protect administration and supplier access through roles, MFA, time limits and logging.
Monitor the operating state
Bring lines, firewalls, switches, access points, players and critical services into one prioritised view.
Turn alerts into action
Runbooks, escalation levels and owners ensure an alert leads to the right response.
Examples from the field
Restaurant: keep the till path available
An access point fails during lunch service. Monitoring identifies the site and impact and escalates only when till or kitchen traffic is at risk.
Hotel: isolate building systems
Guests get simple internet access without reaching access control or building systems. Supplier access is time-limited and auditable.
Signage: content did not arrive
Support can distinguish a CMS, line or player issue from the last connection, version and site state instead of guessing.
Office: investigate an unusual access
An unusual pattern is linked to a site and zone so access can be contained without shutting down the entire location.
From protection to response
Step 1
Define protection needs
Identify critical services, data sensitivity and acceptable downtime for each site type.
Step 2
Design zones and access
Document network segments, firewall rules, remote access and operational ownership.
Step 3
Connect monitoring and runbooks
Give every relevant alert a threshold, owner, first action, escalation path and recovery step.
Step 4
Test real scenarios
Simulate line, device and access failures and improve response before peak operations are affected.
Security is what works during operations.
Let us check whether your site network only raises alarms or also enables the right response.
