Edition: 2026-Q2 State rank: #43 Carriers: 1,736 Domains: 1,539 By [Stefan Efros](https://www.linkedin.com/in/stefanefros-cyberdefense/), CEO & Founder, EFROS Updated · May 19, 2026 No enforced DMARC 77.3% national: 80.1% p=reject 8.6% national: 7.5% Microsoft 365 37.0% national: 38.1% M365 + no DMARC (carriers) 401 national: 92,822 MTA-STS 4.6% national: 3.3% DNSSEC 5.6% national: 6.1% Dead domains 43 of 1,539 scanned Total carriers 1,736 43 with dead domain ## Risk bands — Hawaii carriers Carrier counts by risk band (composite email-security pain score).

Hawaii carriers adopt the enforced p=reject DMARC policy at a meaningfully higher rate than the national pool. At the protective end of the distribution, 8.6% of Hawaii domains are at p=reject, the only DMARC policy that actually instructs receivers to drop spoofed mail. **Microsoft 365 surface.** Microsoft 365 mailflow adoption tracks the national distribution closely, so the 401 M365 carriers in Hawaii with DMARC disabled represent the same "paid-for-but-switched-off" pattern that drives the national headline. That share is **23.1%** of all Hawaii carriers — a one-flag-flip remediation set that any regional MSP or in-house IT lead can clear in a single quarter. **Transport encryption.** MTA-STS adoption (the encrypted-transport policy that prevents DNS-downgrade interception) runs above the national rate, but the absolute floor is still under 10%, well short of where freight payment flows should sit. DNSSEC adoption in Hawaii runs at **5.6%** (vs 6.1% national), which matters for downstream DKIM and MTA-STS validation but is still a minority signal. **Risk-band shape.** 9.2% of Hawaii carriers sit in the critical risk band (score 70+), above the national share of 8.4%. A disproportionate cluster carries simultaneously broken SPF, missing or monitor-only DMARC, and no MTA-STS. The composite pain score blends SPF posture, DMARC enforcement, MTA-STS presence, and DNSSEC, so a carrier clusters in the critical band only when several controls fail together. Remediation that flips DMARC to enforcement plus turns on MTA-STS typically moves a carrier two bands down in one quarter. **What this means for buyers and shippers.** If you are dispatching freight, settling broker payments, or receiving rate confirmations from Hawaii-based carriers, the operational exposure is the 77.3%of domains that cannot stop a stranger from sending email in the carrier's name. Payment-redirect and load-redirect fraud rides on exactly that gap. Verifying a counterparty's DMARC posture before a first wire (a 30-second DNS lookup) is the cheapest control in the freight stack. ## Compare Hawaii with other states States closest in carrier-count rank to Hawaii. Each is scored on the same DNS-derived control set, so the comparison is apples-to-apples.
