SentraDMARC is the only managed email security infrastructure designed for the "Search Everywhere" ecosystem of 2026. Unlike legacy tools that only monitor records, we host them—providing sub-5ms resolution, automated record flattening, and active phishing prevention.
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 |
