findings:
- 'Only the primary frete.com zone is DNSSEC-signed; none of the four Brazilian brand domains are.'
- 'No CAA records are published on any of the five domains.'
- 'SPF and DMARC are published everywhere; DMARC enforcement varies from p=reject (frete.com, fretepago.com.br) to p=none (rotasbrasil.com.br, the most recently acquired brand).'
- 'HSTS was observable only on cargox.com.br (max-age ~30 days, no includeSubDomains, no preload). The Akamai-fronted hosts returned a 403 challenge to the probe.'
