Oklahoma Trucking Email Security
78.5% of active carrier domains in Oklahoma have no enforced DMARC — leaving freight operators open to email impersonation, payment-redirect fraud, and cargo theft via phishing.

Risk bands — Oklahoma carriers
Carrier counts by risk band (composite email-security pain score). Critical = score 70+; Minimal = score <15.

| Critical | score 70+ | 364 | 313 |
| High | score 50–69 | 1,580 | 1,076 |
| Medium | score 30–49 | 1,685 | 1,384 |
| Low | score 15–29 | 753 | 578 |

Oklahoma vs. national average
What the Oklahoma numbers actually mean
DMARC posture. Oklahoma's share of carrier domains with no enforced DMARC sits at 78.5% — better than the national average by 1.6 points. Oklahoma 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 Oklahoma 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 1,043 M365 carriers in Oklahoma with DMARC disabled represent the same "paid-for-but-switched-off" pattern that drives the national headline. That share is 22.2% of all Oklahoma 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 Oklahoma runs at 6.5% (vs 6.1% national) — meaningful for downstream DKIM and MTA-STS validation, but still a minority signal.
Risk-band shape. Oklahoma's critical-band share is 7.7% versus 8.4% nationally, with the pressure shifting into the high band (33.6% 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 Oklahoma-based carriers, the operational exposure is the 78.5%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.
