That leaves this segment open to email impersonation, payment-redirect fraud, and cargo theft via phishing. Edition: 2026-Q2 Segment rank: #12 Carriers: 8,085 Domains: 7,175 By [Stefan Efros](https://www.linkedin.com/in/stefanefros-cyberdefense/), CEO & Founder, EFROS Updated · May 19, 2026 No enforced DMARC 77.1% national: 80.1% p=reject 9.3% national: 7.5% Microsoft 365 40.4% national: 38.1% M365 + no DMARC (carriers) 1,984 national: 92,822 MTA-STS 3.7% national: 3.3% DNSSEC 6.1% national: 6.1% Dead domains 552 of 7,175 scanned Total carriers 8,085 552 with dead domain ## Risk bands — Oilfield Equipment carriers Carrier counts by risk band (composite email-security pain score). Critical = score 70+; Minimal = score <15. | Risk band | Score range | Carriers | Domains | | --- | --- | --- | --- | | Critical | score 70+ | 608 | 564 | | High | score 50–69 | 2,276 | 2,009 | | Medium | score 30–49 | 3,155 | 2,806 | | Low | score 15–29 | 1,412 | 1,182 | | Minimal | score ## Oilfield Equipment vs. national average No enforced DMARC 77.1% vs 80.1% national p=reject adoption 9.3% vs 7.5% national MTA-STS 3.7% vs 3.3% national DNSSEC 6.1% vs 6.1% national ## 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. ## Compare Oilfield Equipment with other cargo segments Segments closest in carrier-count rank to Oilfield Equipment. Each is scored on the same DNS-derived control set, so the comparison is apples-to-apples.
