Firewall-as-a-Service (FWaaS) provides cloud-delivered next-generation firewall capabilities — eliminating the need for physical firewall hardware at branch locations while providing consistent security policy enforcement for all internet-bound traffic regardless of where users and devices connect.
FWaaS is a core SASE component that replaces the data center backhaul model for branch security — but inspection quality, policy migration complexity, and latency impact vary significantly across providers. RLM advises on FWaaS platform selection and the migration from hardware firewalls.
A structured advisory process — from discovery and market evaluation to vendor selection and post-deployment optimization — tailored to your specific environment and objectives.
We document your current firewall architecture — rulesets, inspection policies, network segmentation, and the traffic flows that determine FWaaS requirements — establishing the migration baseline.
We evaluate FWaaS platforms — Palo Alto Prisma Access, Zscaler Internet Access, Cato Networks, Check Point Harmony Connect — against your inspection requirements, policy complexity, and geographic coverage.
Migrating firewall policies to FWaaS is often the most complex part of the transition. We design the policy migration approach — policy rationalization, translation methodology, and validation testing.
FWaaS latency depends on proximity to inspection PoPs. We evaluate PoP coverage for your user locations and design the traffic routing architecture that minimizes inspection latency.
These are the dimensions that consistently separate successful network deployments from costly ones — and the questions RLM will help you answer before any commitment.
FWaaS inspection capabilities vary significantly — SSL/TLS decryption, application identification, threat prevention, and URL filtering quality differ across platforms. Evaluate inspection depth against your security policy requirements.
Complex hardware firewall rulesets don't translate directly to FWaaS policies. Evaluate the effort required to rationalize and migrate your existing policy to the FWaaS model before committing to a platform.
Cloud-delivered inspection adds latency. Evaluate PoP proximity to your user locations and the measured latency impact on your latency-sensitive applications.
FWaaS handles internet-bound traffic; private application access requires ZTNA or SD-WAN integration. Evaluate how the platform handles split-tunneling between internet and private application traffic.
FWaaS must provide the traffic logs required for compliance frameworks. Evaluate log retention, log forwarding to SIEM, and the completeness of connection-level logging for your compliance requirements.
FWaaS licensing costs must be modeled against hardware firewall CapEx and support costs. Evaluate the multi-year TCO including hardware refresh cycles, support contracts, and operational overhead.
"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."
Start with a no-cost conversation with an RLM network advisor — vendor neutral, no agenda, just clarity on the right path forward for your environment.
