Currency 80/100
Maturity consistent
Limiting factor: Resolver agreement is low for this scan — some protocols returned inconsistent results across resolvers
Currentness Excellent
TTL Compliance Excellent
Completeness Degraded
Source Credibility Good
TTL Relevance Adequate
ICuAE Details
The following DNS record TTLs deviate from recommended values. Incorrect TTLs can cause caching issues, slow propagation, or unnecessary DNS traffic.
| Record Type | Observed TTL | Typical TTL | Severity | Context |
|---|---|---|---|---|
| A | 1058s |
1 hour (3600s) |
medium | A TTL is below typical — observed 1058s, typical value is 1 hour (3600s). Short TTLs increase DNS query volume but enable faster propagation. If you are preparing for a migration or need rapid failover, this may be intentional (RFC 1035 §3.2.1). For steady-state production, consider 3600 seconds per NIST SP 800-53 SI-7 relevance guidance. Use the TTL Tuner for profile-specific recommendations. |
| TXT | 4s |
1 hour (3600s) |
high | TXT TTL is below typical — observed 4s, typical value is 1 hour (3600s). Short TTLs increase DNS query volume but enable faster propagation. If you are preparing for a migration or need rapid failover, this may be intentional (RFC 1035 §3.2.1). For steady-state production, consider 3600 seconds per NIST SP 800-53 SI-7 relevance guidance. Use the TTL Tuner for profile-specific recommendations. |
| NS | 16459s |
1 day (86400s) |
medium | NS TTL is below typical — observed 16459s, typical value is 1 day (86400s). Short TTLs increase DNS query volume but enable faster propagation. If you are preparing for a migration or need rapid failover, this may be intentional (RFC 1035 §3.2.1). For steady-state production, consider 86400 seconds per NIST SP 800-53 SI-7 relevance guidance. Use the TTL Tuner for profile-specific recommendations. |
| AAAA | 439s |
1 hour (3600s) |
medium | AAAA TTL is below typical — observed 439s, typical value is 1 hour (3600s). Short TTLs increase DNS query volume but enable faster propagation.

Big Picture Questions
- How often do you actually change this record? If it hasn’t changed in months, a short TTL is generating unnecessary DNS queries without any benefit.
- Are you preparing for a migration or IP change? Short TTLs make sense temporarily — but should be raised back to 1 hour (3600s) once the change is complete.
- Every DNS lookup adds 20–150ms of latency. With a 60s TTL, returning visitors trigger a fresh lookup every minute. With 3600s, they get cached responses for an hour — faster page loads, no extra infrastructure needed.
- Google runs A records at ~30s because they operate a global anycast network and need to steer traffic dynamically. For a typical website without that infrastructure, copying those TTLs increases query volume with zero upside.

Email Security Methodology Can this domain be impersonated by email? No SPF and DMARC reject policy enforced
SPF Record RFC 7208 §4 Consistent
Does this domain declare who may send email on its behalf?
Yes
Success
-all

SPF valid with strict enforcement (-all), 5/10 lookups
v=spf1 include:_spf-a.microsoft.com include:_spf-b.microsoft.com include:_spf-c.microsoft.com include:_spf-ssg-a.msft.net include:_spf1-meo.microsoft.com -all
RFC 7489: -all may cause rejection before DMARC evaluation, preventing DKIM from being checked
RFC 7208 Conformant — This SPF record conforms to the syntax and semantics defined in RFC 7208 §4.
RFC Failure Mode: Unlike DMARC (where unknown tags are silently ignored per RFC 7489 §6.3), SPF with unrecognized mechanisms produces a PermError per RFC 7208 §4.6 — the record fails loudly rather than silently.
Related CVEs:
CVE-2024-7208 (multi-tenant domain spoofing),
CVE-2024-7209 (shared SPF exploitation),
CVE-2023-51764 (SMTP smuggling bypasses SPF)
SPF hard fail (-all): compliance-strong, but can short-circuit DMARC.
RFC 7489 notes that -all can cause some receivers to reject mail during the SMTP transaction — before DKIM is checked and before DMARC can evaluate the result. A message that would pass DMARC via DKIM alignment may be rejected prematurely. For most domains, ~all + DMARC p=reject is the strongest compatible posture — it allows every authentication method (SPF, DKIM, DMARC) to be fully evaluated before a decision is made.
DMARC is set to reject — enforcement is strong. However, some receivers may still reject messages on SPF hard fail before DKIM alignment is checked. Switching to ~all + p=reject would provide the same enforcement with full DMARC compatibility.
DMARC is set to reject — enforcement is strong. However, some receivers may still reject messages on SPF hard fail before DKIM alignment is checked. Switching to ~all + p=reject would provide the same enforcement with full DMARC compatibility.
DMARC Policy RFC 7489 §6.3 Consistent
Are spoofed emails rejected or quarantined?
Yes — reject policy
Success
p=reject

Alignment:
SPF relaxed
DKIM relaxed
No np= tag (DMARCbis) — non-existent subdomains inherit p= policy but adding np=reject provides explicit protection against subdomain spoofing
Forensic reporting (ruf) is configured, but most major providers do not send forensic reports.
RFC 7489 §7.3 warns that forensic reports can expose PII (full message headers or bodies). Google, Microsoft, and Yahoo do not honour ruf= requests. The DMARCbis draft (draft-ietf-dmarc-dmarcbis) has formally removed ruf= from the specification. Consider removing this tag to simplify your record.
RFC 7489 §7.3 — Forensic Reports
RFC 7489 Conformant — DMARC record conforms to RFC 7489 §6.3 with full enforcement.
DMARCbis (Pending): draft-ietf-dmarc-dmarcbis will elevate DMARC to Standards Track, obsolete RFC 7489, replace
pct= with t= (testing flag), add np= (non-existent subdomain policy), and mandate DNS tree walk for policy discovery instead of the Public Suffix List.Related CVEs:

DANE / TLSA Consistent Recon Methodology Can mail servers establish identity without a public CA? via MTA-STS (CA)
DANE not available — Microsoft 365 does not support inbound DANE/TLSA on its MX infrastructure
DANE not deployable on Microsoft 365
Microsoft 365 does not support DANE for inbound mail. Microsoft uses its own certificate pinning mechanism.
Recommended alternative: MTA-STS (already configured)
Email Transport Security
Two mechanisms protect email in transit. DANE is the primary standard; MTA-STS is the alternative for domains that cannot deploy DNSSEC:
- DNSSEC + DANE (RFC 7672) — Cryptographic chain of trust from DNS root to mail server certificate. Eliminates reliance on certificate authorities. No trust-on-first-use weakness. Requires DNSSEC.
- MTA-STS (RFC 8461) — HTTPS-based policy requiring TLS for mail delivery. Works without DNSSEC but relies on CA trust and is vulnerable on first use (§10). Created for domains where “deploying DNSSEC is undesirable or impractical” (§2).
Industry trend: Microsoft Exchange Online enforces inbound DANE with DNSSEC (GA October 2024), and providers like Proton Mail and Fastmail also support DANE. Google Workspace does not support DANE and relies on MTA-STS. Both mechanisms coexist because DANE is backward-compatible — senders skip the check if the domain isn't DNSSEC-signed (RFC 7672 §1.3).
Brand Security Can this brand be convincingly faked? Possible DMARC reject policy blocks email spoofing (RFC 7489 §6.3) and CAA restricts certificate issuance (RFC 8659 §4), but no BIMI brand verification — lookalike domains display identically in inboxes without visual proof of authenticity
BIMI BIMI Spec Consistent Warning
Is the brand identity verified and displayed in inboxes?
No
No BIMI record found
CAA RFC 8659 §4 Consistent Success
Does this domain restrict who can issue TLS certificates?
Yes
CAA configured - specific CAs authorized
0 contactemail "caarecordaware@microsoft.com"
Since September 2025, all public CAs must verify domain control from multiple geographic locations (Multi-Perspective Issuance Corroboration, CA/B Forum Ballot SC-067). CAA records are now checked from multiple network perspectives before certificate issuance.

Public Exposure Checks Are sensitive files or secrets exposed? No
No exposed secrets detected in public page source — same-origin, non-intrusive scan of publicly visible page source and scripts.
No exposed secrets, API keys, or credentials were detected in publicly accessible page source or scripts.
What type of scan is this?
This is OSINT (Open Source Intelligence) collection — we check the same publicly accessible URLs that any web browser could visit. No authentication is bypassed, no ports are probed, no vulnerabilities are exploited.
Is this a PCI compliance scan? No. PCI DSS requires scans performed by an Approved Scanning Vendor (ASV) certified by the PCI Security Standards Council. DNS Tool is not an ASV. If you need PCI compliance scanning, engage a certified ASV such as Qualys, Tenable, or Trustwave.
Is this a penetration test? No. Penetration testing involves active exploitation attempts against systems with authorization. Our checks are passive observation of publicly accessible resources — the same methodology used by Shodan, Mozilla Observatory, and other OSINT platforms.

Domain Security Methodology Can DNS responses be tampered with in transit? Possible DNSSEC is not deployed, DNS responses are not cryptographically verified
DNSSEC RFC 4033 §2 Consistent Unsigned
DNSSEC not configured - DNS responses are unsigned
Enterprise DNS Context: DNSSEC is the only standardized, DNS-verifiable mechanism that cryptographically authenticates responses between authoritative servers and resolvers (RFC 4033 §2, RFC 4035). Without it, DNS responses are technically vulnerable to in-transit tampering. Enterprise operators may employ compensating controls (anycast, DDoS mitigation, private peering, TSIG) — however, these do not provide DNS-layer data authentication to third-party resolvers and are not verifiable via DNS alone.
Visibility: DNS-only — network-layer compensating controls cannot be observed or verified through DNS queries. This assessment reflects what is provable from the DNS evidence available.

Showing 354 of 674 discovered subdomains, curated by security relevance.
Multiple cooperative discovery methods — including CT logs (RFC 6962), DNS probing, and CNAME chain traversal — feed into a unified view.
Well-known service names (mail, vpn, api, sso, admin, etc.), DNS-resolving hosts, and subdomains with the most certificate activity are prioritized.
345 expired-certificate-only subdomains included where relevant.

DNS History Timeline BETA

DNS History Timeline BETA
When was a record added, removed, or changed — and could that change be the problem?
Confirm Your Email Configuration
This tool analyzes DNS records, but to verify actual email delivery, send a test email to Red Sift Investigate. Their tool shows exactly how your emails arrive, including SPF/DKIM/DMARC pass/fail results in the headers.
DATA FRESHNESS & METHODOLOGY
All security-critical records (SPF, DMARC, DKIM, DANE/TLSA, DNSSEC, MTA-STS, TLS-RPT, BIMI, CAA) are queried live from authoritative nameservers and cross-referenced against 5 independent public DNS resolvers (Cloudflare, Google, Quad9, OpenDNS, DNS4EU) at the time of each analysis. No security verdict uses cached data.
Registrar data (RDAP) is cached for up to 24 hours because domain ownership and registration details change infrequently. Certificate Transparency logs (subdomain discovery via RFC 6962) are cached for 1 hour because CT entries are append-only historical records. Sections using cached data are marked with a CACHED badge; live queries show LIVE.
Subdomain curation: 674 subdomains were discovered — the most security-relevant are displayed, prioritized by: well-known service names (mail, vpn, api, sso, admin, etc.), DNS-resolving hosts, and subdomains with the most certificate activity. CNAME chain resolution and provider identification run on the curated set for accuracy. The complete list is available via CSV export.
Intelligence Sources
This analysis used 4 DNS resolvers (consensus), reverse DNS (PTR), Team Cymru (ASN attribution), IANA RDAP (registrar), crt.sh (CT logs), and SMTP probing (transport). All using open-standard protocols.
Verify Report Integrity SHA-3-512 Has this report been altered since generation? Verify below
This cryptographic hash seals the analysis data, domain, timestamp, and tool version into a tamper-evident fingerprint. Any modification to the report data will produce a different hash. This is distinct from the posture hash (used for drift detection) — the integrity hash uniquely identifies this specific report instance.
236764fd128be46c84edf83151dc5f16126d5ed84e73d6f9491835a1586c0aea7c34a737d70e9ef053b4892a3516f3c9a5c5ea7bc03fbd01a7fa958b36ac2187
Evaluations reference 12 RFCs. Methods are reproducible using the verification commands provided. Results reflect DNS state at 15 Apr 2026, 14:12 UTC.
Download the intelligence dump and verify its integrity, like you would a Kali ISO or any critical artifact. The SHA-3-512 checksum covers every byte of the download — deterministic serialization ensures identical hashes across downloads.
After downloading, verify with any of these commands:
Tip: cd ~/Downloads first (or wherever you saved the files).
OpenSSL + Sidecar (macOS, Linux, WSL)
cat dns-intelligence-microsoft.com.json.sha3 && echo '---' && openssl dgst -sha3-512 dns-intelligence-microsoft.com.json
Python 3 (cross-platform)
python3 -c "import hashlib; print(hashlib.sha3_512(open('dns-intelligence-microsoft.com.json','rb').read()).hexdigest())"
sha3sum (coreutils 9+)
sha3sum -a 512 dns-intelligence-microsoft.com.json
Compare the output against the
.sha3 file or the checksum API at /api/analysis/12397/checksum. Hash algorithm: SHA-3-512 (Keccak, NIST FIPS 202).
Every finding in this report is backed by DNS queries you can run yourself. These vetted one-liners reproduce the exact checks used to build this report for microsoft.com. Our analysis adds multi-resolver consensus, RFC-based evaluation, and cross-referencing — but the underlying data is always independently verifiable. We are intelligence analysts, not gatekeepers.
