generated: '2026-07-27' method: probed source: >- live DNS/TLS/HTTP probes of apis.yml + OpenAPI hosts (0-working/probe-domain-security.py), corrected and extended by hand on the same date: the script's HSTS check reported null for hosts that do serve Strict-Transport-Security, and it did not cover the AER-operated Product Reference Data host that serves AGL's plans. Both were re-probed with `curl -D -` and `dig`, and the observed header values are recorded verbatim. hosts: - host: www.agl.com.au role: corporate website https: true http_status: 403 http_status_note: Akamai edge (server AkamaiGHost) denies all non-browser clients. tls_version: TLSv1.3 cert_expires: Oct 12 23:59:59 2026 GMT hsts: true hsts_header: 'max-age=86400 ; includeSubDomains ; preload' hsts_max_age: 86400 hsts_note: >- max-age is 1 day — well below the 31536000 (1 year) that HSTS preload submission requires, despite the preload token being present. - host: public.cdr.agl.com.au role: AGL CDR public base URI https: true http_status: 200 http_status_note: 200 on /cds-au/v1/discovery/status; nginx 404 at the host root, which is correct. tls_version: TLSv1.3 cert_expires: Nov 6 23:59:59 2026 GMT hsts: true hsts_header: 'max-age=63072000; includeSubDomains;' hsts_max_age: 63072000 other_headers: - 'x-content-type-options: nosniff' - 'x-frame-options: DENY' - 'access-control-allow-origin: *' - host: cdr.energymadeeasy.gov.au role: AER-operated central energy Product Reference Data host serving AGL's plans operated_by: Australian Energy Regulator (not AGL) https: true http_status: 200 tls_version: TLSv1.3 cert_expires: Jan 31 23:59:59 2027 GMT hsts: false hsts_note: No Strict-Transport-Security header returned on the AGL PRD path. - host: www.aer.gov.au role: AER documentation host referenced from apis.yml https: true tls_version: TLSv1.3 cert_expires: Oct 5 08:19:20 2026 GMT hsts: null domains: - domain: agl.com.au dnssec: false caa: - 0 issue "amazon.com" - 0 issue "amazontrust.com" - 0 issue "digicert.com" - 0 issue "awstrust.com" - 0 issue "amazonaws.com" - 0 issue "letsencrypt.org" spf: true dmarc: true dmarc_policy: reject - domain: energymadeeasy.gov.au dnssec: false caa: - 0 issuewild "amazon.com" - 0 issuewild "amazonaws.com" - 0 issuewild "amazontrust.com" - 0 issuewild "awstrust.com" spf: true spf_record: 'v=spf1 include:amazonses.com -all' dmarc: true dmarc_policy: quarantine - domain: aer.gov.au dnssec: false caa: [] spf: true dmarc: true dmarc_policy: reject summary: hosts_probed: 4 https_everywhere: true tls_1_3_everywhere: true hsts_on_api_host: true dnssec_anywhere: false caa_published: [agl.com.au, energymadeeasy.gov.au] dmarc_enforcing: [agl.com.au (reject), aer.gov.au (reject), energymadeeasy.gov.au (quarantine)]
