[daily-firewall-report] Daily Firewall Report - May 4, 2026

[github-actions[bot]]

Executive Summary

This report covers firewall activity across all agentic workflows for the 7-day period ending May 4, 2026. A total of 12 workflow runs across 7 distinct workflows were analyzed. Overall firewall health is good — 90.4% of requests were allowed — with all blocked traffic originating from a single workflow (Dev) attempting to reach internal api-proxy endpoints that are not on any allowlist.

Key Metrics

Metric	Value
Workflow runs analyzed	12
Workflows with firewall enabled	7
Total network requests monitored	209
✅ Allowed requests	189 (90.4%)
Blocked requests	20 (9.6%)
Unique blocked domains	2
Block rate	9.6%

Firewall Activity Trends

Request Patterns

The vast majority of firewall activity is legitimate AI engine traffic (Copilot, Anthropic). The Dev workflow stands out as the sole source of blocked traffic, accounting for all 20 blocked requests. The [aw] Failure Investigator workflow generated the highest request volume (74 requests), all to api.anthropic.com, reflecting its extended 6-hour runtime.

Top Blocked Domains

Both blocked endpoints are internal api-proxy addresses (ports 10000 and 10002), not external internet domains. This strongly suggests the Dev workflow is attempting to route through an internal proxy that the firewall is not configured to permit.

Security Recommendations

1. Investigate the Dev workflow — All 20 blocked requests came from this single workflow, targeting api-proxy:10000 and api-proxy:10002. These appear to be internal proxy endpoints. The workflow's network configuration may be misconfigured or missing an explicit AI engine domain allowlist entry. If api-proxy is a legitimate internal routing mechanism for an AI engine, it should be added to the workflow's network.allowed list.

2. No external suspicious domains detected — All blocked traffic is to internal endpoints, not external third-party services. There are no signs of data exfiltration attempts or unauthorized external access.

3. Firewall coverage is healthy — 7 out of 12 runs had firewall enabled. Consider auditing the remaining runs to ensure firewall is intentionally disabled where it is.

4. Anthropic traffic volume — The Failure Investigator workflow made 74 requests to api.anthropic.com in a single 6-hour run. This is expected but worth monitoring for token cost and rate-limit implications.
