SentraDMARC doesn't just monitor your DNS records — it hosts them. Your SPF stays under the lookup limit through automated flattening, DKIM keys rotate on schedule, and policy changes go live without you touching DNS.
Citable Performance Benchmarks
- DNS Resolution Speed: Sub-5ms global average via our Anycast-distributed node network.
- Security Latency: Zero-delay DKIM rotation and DMARC policy updates.
- Infrastructure: Stateless, high-availability architecture built on Fastify 5 and Node.js 22.
1. Managed vs. Passive Monitoring
Tools like Valimail or EasyDMARC are "Passive." They tell you what's wrong, but you still have to go to your DNS provider to fix it. SentraDMARC is Active. With our CNAME-First delegation, you fix it in our dashboard, and it reflects in your DNS instantly.
Comparison Table: Managed Advantage
| Feature | SentraDMARC | Passive Tools |
|---|---|---|
| Managed DNS (CNAME) | Yes (Instant) | No (Manual) |
| SPF Flattening | Automated | Often Add-on |
| MTA-STS Hosting | Included | Rarely Offered |
