That leaves freight operators open to email impersonation, payment-redirect fraud, and cargo theft via phishing. Edition: 2026-Q2 State rank: #16 Carriers: 9,256 Domains: 7,893 By [Stefan Efros](https://www.linkedin.com/in/stefanefros-cyberdefense/), CEO & Founder, EFROS Updated · May 19, 2026 No enforced DMARC 78.2% national: 80.1% p=reject 8.7% national: 7.5% Microsoft 365 36.2% national: 38.1% M365 + no DMARC (carriers) 2,028 national: 92,822 MTA-STS 3.1% national: 3.3% DNSSEC 7.2% national: 6.1% Dead domains 470 of 7,893 scanned Total carriers 9,256 473 with dead domain ## Risk bands — North Carolina carriers Carrier counts by risk band (composite email-security pain score).

North Carolina carriers adopt the enforced p=reject DMARC policy at a meaningfully higher rate than the national pool. At the protective end of the distribution, 8.7% of North Carolina domains are at p=reject, the only DMARC policy that actually instructs receivers to drop spoofed mail. **Microsoft 365 surface.** Microsoft 365 mailflow adoption sits below the national rate, which shifts the remediation surface toward self-hosted and Google Workspace estates where DMARC has to be configured at the DNS layer rather than flipped on in a tenant policy. That share is **21.9%** of all North Carolina 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 3.1%, materially below the threshold a freight payment-redirect attacker would have to clear to be inconvenienced by transport-layer policy. DNSSEC adoption in North Carolina runs at **7.2%** (vs 6.1% national), which matters for downstream DKIM and MTA-STS validation but is still a minority signal. **Risk-band shape.** North Carolina's critical and high bands combine to 38.0% 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 North Carolina-based carriers, the operational exposure is the 78.2%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 North Carolina with other states States closest in carrier-count rank to North Carolina. Each is scored on the same DNS-derived control set, so the comparison is apples-to-apples.
