Azure Firewall

Protect Your Network at Cloud Scale 
Your network perimeter is only as strong as the controls enforcing it. Azure Firewall gives you a fully managed, stateful firewall-as-a-service built natively into Azure so you get enterprise-grade protection without the overhead of managing appliances. 

Centralized Policy Management

Define and enforce network and application rules across all your subscriptions and virtual networks from a single place using Azure Firewall Policy.

We act as an extension of their IT team, responsible for day‑to‑day operations, security monitoring, incident response, and continuous optimization. Our focus is on reducing risk, improving reliability, and ensuring the environment evolves as business needs change. Rather than reactive support, we deliver proactive management, governance, and visibility—allowing clients to focus on their business while we ensure the platform remains secure, compliant, and performing as intended.

Threat Intelligence-Based Filtering

Automatically block traffic to and from known malicious IP addresses and domains using Microsoft's continuously updated threat intel feed.

IDPS (Intrusion Detection & Prevention)

Detect and block known attack patterns and suspicious traffic in real time with signature-based IDPS.

TLS Inspection

Decrypt, inspect, and re-encrypt outbound TLS traffic to catch threats hidden in encrypted sessions.

FQDN Filtering

Control outbound internet access at the domain level not just by IP including dynamic FQDN resolution for services like Windows Update.

Hub-and-Spoke Architecture Support

Deploy Azure Firewall in a hub VNet and route traffic from all connected spoke networks through it for consistent, centralized enforcement.

Forced Tunneling & BGP Route control

Route internet-bound traffic back to on-premises or through specific paths without disrupting ExpressRoute connectivity..

Why Work with Red X Carbon

Deploying Azure Firewall is straightforward. Deploying it right — with a policy hierarchy that scales, UDRs that don't break your existing routing, and rules that are actually maintainable — takes deep hands-on experience. Red X Carbon has designed and implemented Azure Firewall solutions for organizations across healthcare, financial services, and enterprise sectors.

Proven Architecture Patterns

We bring a structured hub-and-spoke design methodology with firewall policy hierarchies (base and child policies) built to scale across subscriptions.

Rule Migration Expertise

We migrate existing firewall rules from NVAs or on-premises appliances to Azure Firewall Policy without service disruption.

UDR and Routing Design

We design User Defined Routes that enforce traffic flows through the firewall without breaking ExpressRoute or spoke-to-spoke connectivity.

Diagnostics and Tuning

We configure structured logging, diagnostic settings, and alert rules so your security team has full visibility into firewall activity from day one.

Policy Governance

We establish naming conventions, change management processes, and rule review cadences to keep your firewall policy maintainable long-term.

Cross-Sector Delivery Experience

Red X Carbon has delivered Azure Firewall solutions for clients in healthcare, financial services, and enterprise — including regulated environments with strict egress controls.
