azure-firewallGuidance for Azure Firewall — managed cloud-native L3-L7 stateful network firewall for centralised egress, east-west, and ingress control.
Azure Firewall is an agent skill from vinayaklatthe/microsoft-security-skills. Guidance for Azure Firewall — managed cloud-native L3-L7 stateful network firewall for centralised egress, east-west, and ingress control. Covers SKU choice (Basic vs Standard vs Premium), Firewall Policy hierarchy, application/network/DNAT rules, threat intelligence and IDPS, TLS inspection, hub-spoke deployment with UDRs, and forced tunneling. WHEN: Azure Firewall, network firewall, egress filtering, FQDN filtering, Firewall Policy, IDPS, TLS inspection, forced tunneling, central network control, firewall SKU…
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Network security, Cloud networking and OSINT. It works with Microsoft Azure. The repository describes itself as: Curated Microsoft Security skills for AI agents - Defender, Sentinel, Entra, Purview, Intune, Security Copilot. The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 15f16df. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
learn.microsoft.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Azure Firewall loads about 1.7k tokens when it runs. Until then it costs about 199 tokens; SKILL.md has 748 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/azure-firewall/SKILL.md (or your agent's skills folder).Azure Firewall is a managed, highly available, cloud-native stateful network firewall used to centrally govern and log traffic, typically deployed in the hub of a hub-spoke network. It is the choke point that enforces a default-deny egress posture across an Azure estate.
Centralising egress (and east-west / ingress) traffic control and inspection across an Azure network estate. Use this skill to pick the SKU, design rules, and deploy in the hub.
Do not use this skill for L7 web app protection (WAF on Front Door / App Gateway), subnet
microsegmentation (NSGs - see azure-network-security-design), or third-party NVA design.
| Requirement | SKU | Notes |
|---|---|---|
| SMB / dev / small estate, < 250 Mbps | Basic | Cost-optimised; no threat intel deny |
| Standard egress filtering, FQDN, threat intel | Standard | Default for most enterprise hubs |
| TLS inspection, IDPS signatures, URL filtering, web categories | Premium | Regulated / high-assurance |
| Multi-hub global deployment | Premium + Firewall Manager + Virtual WAN | Centralised policy at scale |
Rule of thumb: Standard SKU is right for most enterprise hubs in 2026. Move to Premium only when you have a concrete TLS-inspection or IDPS requirement - the certificate / PKI overhead of TLS inspection is real and breaks some apps. Basic only for SMB or sandbox.
Deploy in the hub — Single firewall per region in the hub VNet (with at least two availability zones for resilience). All spokes peer to the hub; egress and east-west traffic flows through. Verify: firewall has public IP for egress, deployed across ≥ 2 AZs, capacity baseline established.
Use Firewall Policy (not classic rules) — Author rules in Azure Firewall Policy with hierarchical parent + child policies (e.g. parent = enterprise baseline, child = region-specific). Don't author rules per firewall. Verify: policy hierarchy mapped; one base policy reused across regional firewalls.
Default-deny + structured rule collections — Order: DNAT (inbound) → Network rules (IP/port/protocol) → Application rules (FQDN/URL). Inside each collection group, priority controls evaluation. Default action = deny. Verify: a probe from a spoke to an unallowed FQDN is logged as deny.
Application rules with FQDN tags — Use built-in FQDN tags (WindowsUpdate, AzureKubernetesService, Office365) for Microsoft service egress instead of hand-curated lists. Custom FQDNs for third-party SaaS.
Force spoke egress through firewall via UDRs — User-defined routes on spoke subnets:
0.0.0.0/0 next hop = firewall private IP. Without UDRs, traffic bypasses the firewall.
Verify: Get-AzEffectiveRouteTable on a spoke NIC shows next hop = firewall.
Enable threat intel + IDPS (Premium) — Threat-intel-based filtering in Deny mode for known-bad IPs / FQDNs. Premium: enable IDPS in Alert+Deny for high-severity signatures; tune false positives.
Stream logs and monitor capacity — Send to Log Analytics / Sentinel using structured firewall logs. Use the workbook for top denied flows, capacity / throughput. Verify: firewall workbook populated; alert on > 80% throughput sustained for 15 minutes.

Guidance for Azure Firewall — managed cloud-native L3-L7 stateful network firewall for centralised egress, east-west, and ingress control. Azure Firewall is an agent skill from vinayaklatthe/microsoft-security-skills. Guidance for Azure Firewall — managed cloud-native L3-L7 stateful network firewall for centralised egress, east-west, and ingress control.
Azure Firewall fits situations like: L7 web application protection (use Front Door / Application Gateway WAF); subnet microsegmentation (use NSGs in azure-network-security-design); third-party NVA design.
Run `npx skills add vinayaklatthe/microsoft-security-skills --skill azure-firewall -a claude-code`. Or copy the skill folder (skills/azure-firewall in vinayaklatthe/microsoft-security-skills) into .claude/skills/azure-firewall in your project. Claude Code loads it when a task matches its description.
Run `npx skills add vinayaklatthe/microsoft-security-skills --skill azure-firewall -a codex`. Or copy the skill folder (skills/azure-firewall in vinayaklatthe/microsoft-security-skills) into .agents/skills/azure-firewall in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add vinayaklatthe/microsoft-security-skills --skill azure-firewall -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/azure-firewall, .gemini/skills/azure-firewall, .github/skills/azure-firewall and .opencode/skills/azure-firewall in your project.
SKILL.md names no scripts, command-line tools or credentials: Azure Firewall is instructions for the agent only.
SKILL.md names 1 domain. As links in the text: learn.microsoft.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Azure Firewall is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.7k tokens (SKILL.md is roughly 6.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
