General Freight vs. national average
What the General Freight numbers actually mean
Segment exposure framing. General freight is the largest single segment and the easiest target for high-volume payment-redirect fraud — a small percentage success rate across a giant pool still pays attacker margins.
DMARC posture. The general freightsegment's share of carrier domains with no enforced DMARC sits at 80.6% — within 0.5 points of the national average. enforced p=reject DMARC adoption tracks the national pool — meaning most domains in this segment either have no DMARC at all or are stuck at the monitor-only p=none policy. At the protective end of the distribution, 7.4% 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 sits below the national rate, which shifts the remediation surface toward self-hosted and Google Workspace estates where DMARC has to be configured at the DNS layer rather than flipped on in a tenant policy. That share is 23.2% of all general freight 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 3.1%, materially below the threshold a freight payment-redirect attacker would have to clear to be inconvenienced by transport-layer policy. DNSSEC adoption across general freight carriers runs at 8.0% (vs 6.1% national).
Risk-band shape. General Freight's critical and high bands combine to 37.5% of segment carriers — close to the national distribution, meaning remediation prioritization here should follow the same shape as the national program.
Best-practice control for this segment. For brokers and shippers running high-frequency general-freight tenders, DMARC verification of every new carrier domain before a first wire is the cheapest fraud control in the stack.
