🔥 Executive Summary

Report date: 2026-09-27 (covering the last 24 hours)

This report analyzes firewall activity across 87 workflows (201 workflow runs) that had the firewall feature enabled during the period. Out of 304 total run directories cached locally, 88 had no run_summary.json file present and were skipped (not malformed — simply absent).

Overall, network activity was overwhelmingly clean: of 13,921 total monitored requests, only 10 were blocked (a 0.07% block rate), spread across just 2 unique domains. This indicates the current firewall allowlists are well-tuned to the workflows' actual needs, with only minor incidental noise from background OS/browser telemetry domains.

⚠️ Note on chart generation: The firewall-chart-generator sub-agent could not be invoked in this run (400 model "gpt-5.4-mini" is not accessible via the /chat/completions endpoint). Trend charts are omitted from this report; all underlying data is still presented in the tables below.

⚠️ **Note on policy rule (redacted) No policy_analysis field was present in any of the 201 cached run_summary.json files for this period, so Section 4 (Policy Rule Attribution) is not available this cycle. Only domain-level allow/block counts (from firewall_analysis) could be aggregated.

📊 Key Metrics

Metric	Value
Workflows analyzed	87
Runs analyzed	201
Total network requests monitored	13,921
✅ Allowed requests	13,911
🚫 Blocked requests	10
Block rate	0.07%
Unique blocked domains	2

Terminology Note: Allowed requests successfully reached their destination; blocked requests were prevented by the firewall.

🚫 Top Blocked Domains

Domain	Times Blocked	Workflows	Category
clients2.google.com	7	Daily Model Inventory Checker, Smoke Agent: scoped/approved, Smoke Claude, Smoke Copilot, Smoke Copilot - AOAI (apikey), Smoke Copilot ARM64	Other (Google Chrome/OS update-check telemetry)
host.docker.internal:4173	3	Smoke Agent: scoped/approved	Development Services (local Docker container callback)

Section 4: Policy Rule Attribution

Not available this cycle — the cached run_summary.json files for this period do not include a policy_analysis field (no rule-level hit counts, SSL Bump/DLP status, or explicit rule attribution for denies). All denial data available is limited to the domain-level firewall_analysis.requests_by_domain breakdown shown above and in the details below.

🔐 Security Recommendations

• clients2.google.com is a well-known Google Chrome/ChromeOS component-update check-in domain, likely triggered incidentally by a headless browser or system process during CI (e.g. Playwright/Chromium-based tooling). It carries low security risk but appears repeatedly across many unrelated "Smoke" workflows and the "Daily Model Inventory Checker." If none of these workflows intentionally use Chrome update services, no allowlisting action is needed — the block is working as intended and this traffic is expected background noise from bundled browser binaries.
• host.docker.internal:4173 appearing only in "Smoke Agent: scoped/approved" suggests a local container is attempting to call back to a host-side service (port 4173 is the default Vite preview server port). This looks like an intentional local dev/test dependency that may need to be added to that workflow's network.allowed list if the smoke test expects to reach a locally-served preview app; otherwise, this is likely a leftover config that should be removed from the test setup.
• No suspicious or unexpected third-party/tracking domains were observed this period — overall block volume (10 requests / 13,921 total) is negligible and does not indicate a firewall misconfiguration or security incident.
• Data gap: Policy rule (policy_analysis) data was absent from all cached summaries this period. To enable Section 4 rule-level attribution and rule-effectiveness analysis (busiest allow rules, deny rules catching the most traffic, unused rules), ensure the firewall log collector captures and persists policy rule hit counts and per-request rule attribution in future runs.
• Chart generation gap: The chart-generation sub-agent was unreachable this cycle due to a model access error; consider verifying firewall-chart-generator agent configuration/model availability before the next scheduled run so trend visualizations can resume.
