That leaves freight operators open to email impersonation, payment-redirect fraud, and cargo theft via phishing. Edition: 2026-Q2 State rank: #49 Carriers: 1,069 Domains: 987 By [Stefan Efros](https://www.linkedin.com/in/stefanefros-cyberdefense/), CEO & Founder, EFROS Updated · May 19, 2026 No enforced DMARC 74.9% national: 80.1% p=reject 9.0% national: 7.5% Microsoft 365 41.2% national: 38.1% M365 + no DMARC (carriers) 281 national: 92,822 MTA-STS 3.6% national: 3.3% DNSSEC 3.3% national: 6.1% Dead domains 45 of 987 scanned Total carriers 1,069 45 with dead domain ## Risk bands: Rhode Island carriers Carrier counts by risk band (composite email-security pain score).

Rhode Island carriers adopt the enforced p=reject DMARC policy at a meaningfully higher rate than the national pool. At the protective end of the distribution, 9.0% of Rhode Island domains are at p=reject, the only DMARC policy that actually instructs receivers to drop spoofed mail. **Microsoft 365 surface.** Microsoft 365 mailflow adoption is heavier than the national distribution, which is consequential: every M365 tenant already includes the controls needed to enforce DMARC, so the 281 M365 carriers in Rhode Island with DMARC disabled are leaving paid-for protection switched off. That share is **26.3%** of all Rhode Island 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 sits at 3.6%, materially below the threshold a freight payment-redirect attacker would have to clear to be inconvenienced by transport-layer policy. DNSSEC adoption in Rhode Island runs at **3.3%** (vs 6.1% national), which matters for downstream DKIM and MTA-STS validation but is still a minority signal. **Risk-band shape.** Rhode Island's critical and high bands combine to 37.0% of state carriers, close to the national distribution, so remediation prioritization here should follow the same shape as the national program. 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 Rhode Island-based carriers, the operational exposure is the 74.9% 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 Rhode Island with other states States closest in carrier-count rank to Rhode Island. Each is scored on the same DNS-derived control set, so the comparison is apples-to-apples.
