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. 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.
