Immunai Domain Security

    No Strict-Transport-Security response header. Served by Flywheel/5.1.0 (managed

  note: >-
    An A record exists but no Immunai service answers on it. TCP 443 connects to a
    Google Cloud front end, then the TLS handshake is reset before any certificate is
    presented (no peer certificate available). Port 80 does not answer either. This is
    a stale DNS record pointing at a Google Cloud address that no longer terminates for
    this hostname — not an Immunai API host.

  tls_version: TLSv1.3
  cert_expires: Aug 26 23:59:59 2026 GMT
  hsts: null
  dns: 34.144.219.193
  http_status: 403
  note: >-
    An A record exists but the address is not serving Immunai. TLS completes and
    presents a certificate for an unrelated third party — subject CN=*.asa.com.br,
    issued by ZeroSSL — so the hostname fails certificate validation for any client.
    Ignoring validation, the Google Cloud front end returns 403 Forbidden. This is a
    dangling DNS record aimed at a Google Cloud address now held by another tenant.

  summary: >-
    Two immunai.com subdomains publish A records into Google Cloud address space where
    no Immunai service is reachable. app.immunai.com presents a valid certificate for a
    wholly unrelated domain (*.asa.com.br), which is the signature of an address
    released back to the cloud provider and reallocated to another tenant while the DNS
    record was left in place. Recorded as observed fact; no exploitation was attempted
    and no takeover is asserted.
  observed: '2026-08-04'
- id: no-hsts
  severity: informational
  hosts:
  - www.immunai.com
  summary: >-
    The primary web host does not send Strict-Transport-Security, so it does not opt
    into HSTS preloading or protect against a first-request downgrade.
  observed: '2026-08-04'
- id: no-dnssec
  severity: informational
  hosts:
  - immunai.com
  summary: The immunai.com zone is not DNSSEC signed.
  observed: '2026-08-04'
strengths:
- CAA is published and pins issuance to Let's Encrypt, Amazon and DigiCert.
- CAA carries an iodef reporting address (security@immunai.com) for certificate misissuance.
- SPF is published and DMARC is enforced at policy p=reject.
- TLS 1.3 on the primary web host.

  note: >-
    api.immunai.com and app.immunai.com were recorded as unresolved by the prior
    enrichment round. They do resolve; this round probed them directly and recorded the
    real state. Neither serves an Immunai API.
