reactive-biosciences-domain-security.yml Raw ↑ 
generated: '2026-07-20'
method: probed
source: live DNS/TLS/HTTP probes of the organization domain (apis.yml declares no
  API hosts; company website is pre-launch, so the registrable org domain was probed
  directly)
hosts:
- host: reactivebio.com
  https: true
  tls_version: TLSv1.3
  cert_expires: Mar  2 23:59:59 2027 GMT
  cert_cn: '*.wpengine.com'
  cert_matches_host: false
  hsts: false
  note: TLS terminates on WP Engine with a wildcard *.wpengine.com certificate that
    does not match the host; the site returns HTTP 404 "not configured", i.e. the
    public website is not yet launched.
domains:
- domain: reactivebio.com
  dnssec: false
  caa: []
  spf: true
  spf_record: v=spf1 include:spf.protection.outlook.com -all

  dmarc_record: v=DMARC1;p=reject;sp=reject;pct=100;ri=86400;fo=1;
  mx: reactivebio-com.mail.protection.outlook.com
  note: Email is on Microsoft 365; strong outbound email posture (SPF hard-fail plus
    DMARC p=reject). No CAA and no DNSSEC.
- domain: reactivebiosciences.com
  dnssec: false
  caa: []
  spf: false
  dmarc: false
  note: Parked/for-sale lander (GoDaddy parking); returns HTTP 200 for every path
    including /.well-known/* and /security.txt, so those responses are not genuine
    endpoints. No API or developer surface.
