That leaves freight operators open to email impersonation, payment-redirect fraud, and cargo theft via phishing. Edition: 2026-Q2 State rank: #29 Carriers: 4,768 Domains: 3,748 By [Stefan Efros](https://www.linkedin.com/in/stefanefros-cyberdefense/), CEO & Founder, EFROS Updated · May 19, 2026 No enforced DMARC 75.6% national: 80.1% p=reject 10.9% national: 7.5% Microsoft 365 40.8% national: 38.1% M365 + no DMARC (carriers) 1,093 national: 92,822 MTA-STS 3.9% national: 3.3% DNSSEC 5.6% national: 6.1% Dead domains 227 of 3,748 scanned Total carriers 4,768 227 with dead domain ## Risk bands — Kansas carriers Carrier counts by risk band (composite email-security pain score).

Kansas carriers adopt the enforced p=reject DMARC policy at a meaningfully higher rate than the national pool. At the protective end of the distribution, 10.9% of Kansas 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 1,093 M365 carriers in Kansas with DMARC disabled are leaving paid-for protection switched off. That share is **22.9%** of all Kansas 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 3.9%, materially below the threshold a freight payment-redirect attacker would have to clear to be inconvenienced by transport-layer policy. DNSSEC adoption in Kansas 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.** Kansas's critical-band share is 7.3% versus 8.4% nationally, with the pressure shifting into the high band (29.1% of state carriers) where one or two control gaps still leave room for impersonation. 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 Kansas-based carriers, the operational exposure is the 75.6%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 Kansas with other states States closest in carrier-count rank to Kansas. Each is scored on the same DNS-derived control set, so the comparison is apples-to-apples.
