The Texas story: Texas has the largest public-sector entity count of any state (6,365) with exceptional domain coverage (73% vs 51% national avg). K-12 performance is a standout — 67.2% DMARC ranks in the top 3 nationally. The challenge is Texas's 3,035 special districts: water districts, MUDs, hospital districts, and ESDs make up nearly half of all TX entities and likely have the lowest authentication rates, dragging the overall state average down to #21.

Recommended DIR Action Items — Based on Data Findings

  1. Special districts are the highest-risk segment: 3,035 TX special districts (water, MUD, hospital, ESD) likely have DMARC below 30%. A targeted DIR outreach campaign could significantly move the state's overall ranking.
  2. SPF-to-DMARC conversion opportunity: Texas has 78.3% SPF but only 46.9% DMARC — roughly 31pp of entities have SPF deployed but haven't enforced DMARC policy. A DIR directive or guidance document could accelerate this final step.
  3. Gateway adoption lags national average: TX proxy rate (12.8%) is below the 14.2% national avg. DIR can recommend qualified email security gateways to state entities through the Texas DIR Cooperative Contracts program.
  4. Leverage K-12 success: TX K-12 performance (#3 nationally) suggests that TEA guidance and district IT consolidation programs work. Replicate this model for municipal and special district sectors via COG outreach.
