Zendrive Domain Security

generated: '2026-09-05'
method: probed
source: dns + tls probe of zendrive.com and docs.zendrive.com
name: Zendrive domain security posture
description: >-
  Probed by hand rather than by probe-domain-security.py, which reported "no-hosts" because
  this record deliberately wires no Website pointer and no API baseURL — Zendrive has no live
  web host to point at. The DNS-layer posture is still measurable, and it is the most
  interesting finding in this profile: the zendrive.com zone is actively maintained even
  though nothing is served from it. A Google Trust Services certificate covering zendrive.com
  and *.zendrive.com was issued on 2026-08-26 (Cloudflare Universal SSL), DMARC is at
  p=reject with strict alignment and a live reporting mailbox, and CAA is a long, curated
  issuer allowlist with an iodef security contact. Someone is still holding and defending this
  domain; they have simply removed every A record.

    reachable: false
    note: No A/AAAA record. Connection cannot be established, so TLS and HSTS are unmeasurable at this host.

      note: >-
        The iodef address is a CAA certificate-violation reporting contact (RFC 8659), NOT a
        vulnerability disclosure program. It is recorded as a security contact of record and
        nothing more; no Security or VulnerabilityDisclosure pointer is emitted from it.

      present: false
      note: No TXT records at all on the apex, so no SPF policy is published.

      A currently valid certificate, issued well after the company wound down its developer
      program — consistent with Cloudflare Universal SSL renewing automatically for a zone
      that is still on the account.
  dns:
    a_records:
    - 172.67.161.199
    - 104.21.9.243
    provider: Cloudflare
findings:
- Domain is retained and actively certificated, but serves nothing.
- DNSSEC is not enabled.
- DMARC is strong (p=reject, sp=reject, strict alignment); SPF is absent, which is a real gap.
- CAA is present and unusually thorough, with an iodef security contact.
- No HSTS can be observed anywhere, because no host serves a successful response.
