Mobile network firewalls protect the cellular-connected edge — enforcing security policies for mobile devices, mobile hotspots, cellular-connected branch offices, and IoT endpoints that traverse public cellular networks without the security controls of a corporate WAN.
Cellular-connected devices often bypass enterprise network security controls — traffic flows directly from device to internet without traversing the corporate firewall. Mobile firewall solutions address this through cloud-delivered security services, on-device VPN with firewall enforcement, or cellular gateway firewalls that apply corporate policies to all traffic traversing the mobile connection. RLM advises on mobile security architecture that extends enterprise security policy to cellular-connected endpoints.
A structured advisory process — from environment assessment and carrier/vendor evaluation to deployment support and ongoing optimization.
We assess the security posture of your mobile environment — documenting traffic flows for cellular-connected devices, identifying the security controls that are bypassed on cellular connections, and the threat exposure created by uncontrolled mobile traffic.
We design the mobile firewall strategy — evaluating cloud-delivered security (SASE/SSE for mobile), on-device security with enterprise VPN, and gateway-level cellular firewall appliances — against your threat model and management architecture.
We design the policy enforcement architecture for mobile traffic — DNS security filtering, application-layer inspection, geo-blocking for high-risk regions, and the compliance enforcement that aligns mobile policy with corporate network security standards.
We design integration between mobile firewall controls and enterprise security infrastructure — SIEM log integration, threat intelligence feeds, and the identity-based policy enforcement that applies per-user security policies to mobile traffic.
The dimensions that separate high-performing mobility deployments from costly ones — and the questions RLM helps you answer before any commitment.
Traditional VPN back-hauls all mobile traffic through corporate infrastructure — adding latency and WAN costs. SASE architectures enforce security at cloud points of presence closer to users. Evaluate the trade-offs for your application landscape and cloud adoption level.
Security controls that add latency or break application functionality reduce adoption. Evaluate the user experience impact of mobile firewall implementations — particularly split-tunnel vs. full-tunnel VPN configurations.
IoT devices often can't run endpoint security agents. Evaluate gateway-level cellular firewall controls that protect IoT device traffic without requiring on-device software.
Some compliance frameworks require documentation of network security controls for mobile devices. Evaluate whether mobile firewall capabilities satisfy your compliance audit requirements — particularly for PCI, HIPAA, and SOC 2.
SASE security enforcement adds latency relative to direct internet access. Evaluate regional point-of-presence coverage and the latency impact on latency-sensitive applications before committing to cloud-delivered mobile security.
"RLM helped us rationalize our mobile fleet across four carriers and cut our monthly spend by 31%. They handled the whole transition — we didn't lose a single device."
"We needed private LTE across 12 distribution centers. RLM mapped the vendors, ran the RFP, and had us live in 90 days. Their knowledge of the carrier landscape is unmatched."
