Guest networking provides internet access to visitors, contractors, and personal devices without exposing internal corporate resources — using captive portals, VLAN segmentation, and bandwidth management to deliver a professional guest experience while maintaining security separation.
Guest WiFi that's misconfigured or inadequately isolated is a security risk. RLM advises on guest network architecture, captive portal design, and the security controls that provide a good guest experience while protecting your corporate environment.
A structured advisory process — from discovery and market evaluation to vendor selection and post-deployment optimization — tailored to your specific environment and objectives.
We define guest network requirements — expected concurrent users, bandwidth needs, authentication requirements (open, social login, registration, sponsor approval), and the compliance requirements that govern internet access.
We design the guest network segmentation — VLAN isolation, firewall policy between guest and corporate networks, DNS filtering, and the guest DHCP/addressing scheme — that provides proper separation.
We evaluate captive portal platforms and design the guest authentication experience — branded portal, authentication methods, terms acceptance, and session management — appropriate for your guest population and brand standards.
Guest networks require bandwidth management to prevent guest traffic from impacting corporate users. We design the bandwidth policies, rate limiting, and application controls appropriate for your guest use cases.
These are the dimensions that consistently separate successful network deployments from costly ones — and the questions RLM will help you answer before any commitment.
Guest VLAN isolation must be complete — guests should not be able to reach corporate VLANs, printers, internal services, or management interfaces even through firewall misconfiguration. Evaluate the isolation architecture thoroughly.
The appropriate authentication model depends on your guest population: open access for retail customers, registration for visitors, sponsor approval for contractors. Evaluate security vs. friction for each model.
Guest networks benefit from DNS filtering to prevent malware distribution and compliance liability from inappropriate content. Evaluate the filtering approach and its management overhead.
Without bandwidth management, individual guest devices can consume disproportionate capacity. Evaluate per-device rate limiting and the mechanism for prioritizing corporate traffic over guest traffic during periods of congestion.
In some jurisdictions, providing public WiFi creates logging and compliance obligations. Evaluate the logging requirements and the liability protections appropriate for your guest networking scenario.
BYOD corporate devices on guest networks create management complexity and potential security issues. Evaluate whether your guest network is truly guest-only or whether it needs to support corporate device connectivity with appropriate access controls.
"RLM gave us an objective view of our network options that no single vendor could. We replaced aging MPLS across 40 locations and came in 28% under our original budget."
"The RLM team understood our network complexity from day one. Their vendor-neutral approach helped us find the right solution — not just the one with the biggest marketing budget."
