The Daily Security Observability Report for 2026-07-06 analyzes 20 firewall-enabled workflow runs from the last 7 days across the github/gh-aw repository. Firewall telemetry from 17 sandbox sessions reveals a healthy posture with a low 1.3% block rate (12 blocked out of 899 total requests). Two distinct domains were blocked: proxy.golang.org (Go module proxy, 3 blocks) and awmg-mcpg (internal MCP gateway, 9 blocks), both consistent with expected policy enforcement — neither represents external threat activity.
The DIFC integrity-filtering system recorded zero filtered events in the last 7 days, indicating either no integrity/secrecy policy violations occurred or the filtered-integrity log collection timed out. The cached DIFC snapshot from 2026-06-23T16:50:31Z is 13 days old and was treated as stale; fresh collection also returned no events. This is a positive signal — the agentic workflows are operating within their configured integrity boundaries.
No cross-cutting concerns were identified between the two signals; no workflow appeared in both firewall block lists and DIFC filtering simultaneously.

📈 Firewall Request Trends
Firewall activity peaked on 2026-07-06, accounting for the majority of observed requests (469 allowed, 9 blocked), consistent with a high-volume day of workflow executions. Earlier dates (2026-06-27 and 2026-06-30) show moderate traffic with minimal blocking. The block rate has remained consistently low (under 2%) across all observed days, indicating a stable and well-tuned allowlist policy.
Top Blocked Domains
Two domains account for all 12 blocked requests: awmg-mcpg (9 blocks, the internal MCP gateway host) and proxy.golang.org (3 blocks, the Go module proxy). The awmg-mcpg blocks are expected as agent sandboxes should not be directly accessing the MCP gateway host via the outbound proxy. The proxy.golang.org blocks indicate Go build or module fetch attempts from within the agent sandbox, which should be allowlisted if Go development workflows are expected.

🔒 Firewall Security Recommendations
Add proxy.golang.org to the allowlist if Go development workflows (e.g., Daily Formal Spec Verifier) need to fetch Go modules during execution. This domain is blocked 3 times and causes potential build failures. Consider also adding sum.golang.org and storage.googleapis.com which are typically needed alongside proxy.golang.org.
Investigate awmg-mcpg direct access attempts from agent sandboxes. The internal MCP gateway should only be accessed via the designated DIFC proxy, not directly through the outbound firewall proxy. Review the Test Quality Sentinel baseline configurations to ensure MCP is properly routed.
Verify api.pi.ai allowlist entry — the Pi AI endpoint is allowlisted but no traffic was observed in this period. If this endpoint is no longer used, consider removing it to reduce the attack surface.
Review historical block spike — the cached historical data shows a large blocking event on 2026-06-22 (8,345 blocked, likely Google API/browser automation domains). Ensure any browser-based workflows are running in appropriately configured sandboxes with their own allowlist profiles.

📈 DIFC Events Over Time
No DIFC integrity-filtered events were recorded in the last 7 days. This may reflect genuine policy compliance across all agentic runs, or the DIFC integrity log collector may have timed out before completing its scan (the filtered_integrity query exceeded the 60-second timeout). The cached DIFC snapshot is from 2026-06-23 and was treated as stale (> 7 days).
🔧 Top Filtered Tools
No tools triggered DIFC filtering in the analysis window.
🏷️ Filter Reasons and Tags
No integrity or secrecy tag violations were recorded. The DIFC system appears to be functioning but may require log collection configuration review given the timeout encountered.

💡 DIFC Tuning Recommendations
Investigate DIFC log collection timeout — the filtered_integrity logs query timed out (60s), preventing fresh DIFC data collection. Consider increasing the timeout or reducing the collection window to avoid missing data in future reports.
Update the DIFC cache snapshot — the cached snapshot is 13 days old (2026-06-23), exceeding the 7-day freshness window. The next successful run should update the cache at /tmp/gh-aw/cache-memory/security-observability/filtered-logs.snapshot.json.
Confirm DIFC coverage — validate that all 20 firewall-enabled workflows analyzed also have DIFC coverage enabled. A zero-event result with no timeout on collection would be a strong positive signal, but a timeout makes it ambiguous.
Cross-correlate with historical data — the previous DIFC snapshot from 2026-06-23 also showed 0 runs, suggesting either this is a period of true compliance or the collection mechanism has been consistently failing. Investigate the DIFC log pipeline health.
