By Cargo / Liquids / Gas (Tanker)
Liquids / Gas (Tanker) Carriers — Email Security
70.9% of active liquids / gas (tanker) carrier domains have no enforced DMARC. That leaves this segment open to email impersonation, payment-redirect fraud, and cargo theft via phishing.

Liquids / Gas (Tanker) vs. national average
What the Liquids / Gas (Tanker) numbers actually mean
Segment exposure framing. Liquids/gas tanker fleets handle high-value, environmentally sensitive cargo. A payment-redirect or load-redirect attack can also create regulatory liability for the shipper if the receiving party is not the intended consignee.
DMARC posture. The liquids / gas (tanker)segment's share of carrier domains with no enforced DMARC sits at 70.9%, better than the national average by 9.2 points. Liquids / Gas (Tanker) carriers adopt enforced p=reject DMARC at a meaningfully higher rate than the national pool. At the protective end of the distribution, 12.3% 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 4,076 M365 carriers in this segment with DMARC disabled are leaving paid-for protection switched off. That share is 24.4% of all liquids / gas (tanker) 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 (the encrypted-transport policy that prevents DNS-downgrade interception) runs above the national rate, but the absolute floor is still under 9%, well short of where freight payment flows should sit. DNSSEC adoption across liquids / gas (tanker) carriers runs at 5.2% (vs 6.1% national).
Risk-band shape. Liquids / Gas (Tanker)'s critical-band share is 6.3% versus 8.4% nationally, with the pressure shifting into the high band (23.5% of segment carriers) where one or two control gaps still leave room for impersonation.
Best-practice control for this segment. Operators dispatching liquid/gas tanker loads should require DMARC-verified email and BSA/AML-grade payee verification before any wire authorization.
