By Cargo / Oilfield Equipment
Oilfield Equipment Carriers — Email Security
77.1% of active oilfield equipment carrier domains have no enforced DMARC. That leaves this segment open to email impersonation, payment-redirect fraud, and cargo theft via phishing.

| High | score 50–69 | 2,276 | 2,009 |
| Medium | score 30–49 | 3,155 | 2,806 |

Oilfield Equipment vs. national average
What the Oilfield Equipment numbers actually mean
Segment exposure framing. Oilfield-equipment carriers move on rig-completion timelines where a missed delivery cascades into rig-day costs measured in five figures per day.
DMARC posture. The oilfield equipmentsegment's share of carrier domains with no enforced DMARC sits at 77.1%, better than the national average by 3.0 points. Oilfield Equipment carriers adopt enforced p=reject DMARC at a meaningfully higher rate than the national pool. At the protective end of the distribution, 9.3% of segment domains are at p=reject, the only DMARC policy that actually instructs receivers to drop spoofed mail.
Microsoft 365 surface. Microsoft 365 mailflow adoption runs heavier than the national distribution. Every M365 tenant already includes the controls needed to enforce DMARC, so the 1,984 M365 carriers in this segment with DMARC disabled are leaving paid-for protection switched off. That share is 24.5% of all oilfield equipment carriers — a one-flag-flip remediation set that segment-specific MSPs can clear in a single quarter without touching DNS infrastructure.
Transport encryption. MTA-STS adoption sits at 3.7%, materially below the threshold a freight payment-redirect attacker would have to clear to be inconvenienced by transport-layer policy. DNSSEC adoption across oilfield equipment carriers runs at 6.1% (vs 6.1% national).
Risk-band shape. Oilfield Equipment's critical-band share is 7.5% versus 8.4% nationally, with the pressure shifting into the high band (28.2% of segment carriers) where one or two control gaps still leave room for impersonation.
Best-practice control for this segment. Operators dispatching oilfield equipment should require DMARC-verified mail and treat carrier email-security posture as part of the same vendor-management discipline as DOT and rig-pad safety compliance.
