Daily Firewall Report - 2026-04-02

[github-actions[bot]]

Executive Summary

This daily firewall report covers all agentic workflow runs with the firewall feature enabled over the past 7 days. Analysis is based on 33 runs from 2026-04-02, representing today's activity. The overall block rate is very low at 1.0% — the vast majority of network requests were served correctly, with only 8 blocked requests across 4 unique domains. All blocked requests appear to stem from codex/smoke-test workflows that attempted to access domains outside their configured allowlists.

📈 Firewall Activity Trends

Request Patterns

The firewall processed 805 total requests today, with an excellent 99.0% allow rate. The 8 blocked requests (1.0% block rate) are all attributable to smoke-test and changeset-generation workflows that attempted connections to non-allowlisted domains. This low block rate indicates that production workflows have well-configured network permissions.

Top Blocked Domains

The most-blocked domain is chatgpt.com:443 (3 blocks), followed by github.com:443 and api.github.com:443 (2 blocks each). These blocks appear in smoke-test and changeset generator workflows — likely expected test behavior to verify firewall enforcement. The ab.chatgpt.com:443 domain (1 block) is a subdomain of chatgpt.com, also blocked in the same context.

Top Blocked Domains

Domain	Blocks	Block Rate	Workflows	Category
chatgpt.com:443	3	–	Changeset Generator, Smoke Call Workflow, Smoke Codex	AI Services
github.com:443	2	–	Changeset Generator, Smoke Call Workflow	Development
api.github.com:443	2	–	Changeset Generator, Smoke Call Workflow	Development
ab.chatgpt.com:443	1	–	Smoke Call Workflow	AI Services

Note on github.com and api.github.com blocks: These domains appear blocked in smoke-test and changeset-generator runs that use the codex engine with restricted allowed_domains: [defaults, node, go]. The Codex engine attempted to access GitHub APIs directly rather than through the GitHub MCP server — this is expected behavior verified by the smoke tests.

Security Recommendations

1. ✅ No production workflow concerns — All blocked domains were in smoke-test or CI validation workflows. These blocks appear intentional (testing firewall enforcement).

2. 🔧 Codex engine network access — The Changeset Generator workflow using the codex engine had blocked access to github.com and api.github.com. If this workflow needs GitHub access, consider using the GitHub MCP server toolset (tools.github.toolsets: [default]) instead of direct API access, as the Copilot agent cannot access api.github.com directly.

3. 🚫 ChatGPT domain blocks — chatgpt.com and ab.chatgpt.com were blocked across multiple smoke-test workflows. These appear to be probe requests from the Codex engine trying to reach its backend. If these workflows require OpenAI/Codex API access, ensure api.openai.com is in the allowlist (it is allowed by the defaults preset).

4. 📊 Low block rate is healthy — A 1.0% block rate with all blocks in test workflows indicates good network permission hygiene across production workflows. No suspicious or unexpected domain access patterns were detected.

5. 📈 Monitor for trends — Only one day of data is available in this analysis period. Running this report daily will build historical trends to detect anomalies over time.
