generated: '2026-08-10' method: probed source: live DNS/TLS/HTTP probes of apis.yml + OpenAPI hosts note: >- The centrical.com row is written by 0-working/probe-domain-security.py from apis.yml. The centrical.me rows were measured by hand on 2026-08-10 with the same method (openssl s_client for TLS version and cert expiry, HEAD for HSTS, dig for DS/CAA/SPF/DMARC) after a DNS sweep found Centrical's production application and API hosts on its second domain, which apis.yml does not reference. Two findings worth naming: centrical.com sets an HSTS max-age of only 300 seconds (5 minutes), which is far too short to offer real protection and below the 31536000 the centrical.me app hosts use; and api.centrical.me — the production API host — sends no HSTS header at all. Neither domain publishes DNSSEC or CAA. hosts: - host: centrical.com role: marketing site (WordPress) https: true tls_version: TLSv1.3 cert_expires: Sep 30 12:47:49 2026 GMT hsts: true hsts_max_age: 300 hsts_include_subdomains: false note: HSTS max-age of 300s is effectively non-protective. - host: api.centrical.me role: production API host (AWS API Gateway, us-east-1) https: true tls_version: TLSv1.3 cert_expires: Feb 1 23:59:59 2027 GMT cert_issuer: Amazon RSA 2048 M01 hsts: false hsts_max_age: null note: No Strict-Transport-Security header on the API host. - host: app.centrical.me role: tenant customer application (CloudFront) https: true tls_version: TLSv1.3 cert_expires: Nov 30 23:59:59 2026 GMT hsts: true hsts_max_age: 31536000 hsts_include_subdomains: true - host: docs.centrical.me role: tenant customer application (CloudFront) https: true tls_version: TLSv1.3 cert_expires: Nov 30 23:59:59 2026 GMT hsts: true hsts_max_age: 31536000 hsts_include_subdomains: true - host: powerup.centrical.me role: mobile/PowerUp client SPA (CloudFront) https: true tls_version: TLSv1.3 cert_expires: Nov 30 23:59:59 2026 GMT hsts: true hsts_max_age: 31536000 hsts_include_subdomains: true domains: - domain: centrical.com dnssec: false caa: [] spf: true dmarc: true dmarc_policy: quarantine - domain: centrical.me dnssec: false caa: [] spf: true spf_record: 'v=spf1 include:spf.protection.outlook.com include:spf.mandrillapp.com include:mail.zendesk.com -all' dmarc: true dmarc_policy: quarantine dmarc_rua: dmarc-reports@centrical.me
