Harden your perimeter against phishing and ensure your emails reach the primary inbox. Every. single. time.Stop compromising between security and deliverability. We hardens your domain perimeter against phishing while ensuring your brand reaches the primary inbox - every. single. time.
And 2 000+ other registrars. We integrate seamlessly with any platform that allows CNAME records.
SentraDMARC isn't just a monitor. It actively enforces policies across your entire email infrastructure.
Enforced Encryption
All features deployed via CNAME delegation. No infrastructure changes required.
It's not just about compliance. Failing to enforce email governance leads to compounding, catastrophic damage to your business.
Without strict protocol enforcement across your domain, email providers silently drop or quarantine up to 20% of your legitimate transactional emails over time.
A DMARC policy of p=none leaves your perimeter defenseless. Attackers can seamlessly impersonate your executives to your clients.
Unmanaged sender sources eventually lead to aggregate blacklisting. When your legitimate IPs get flagged, automated recovery takes months.
Stop wrestling with brittle DNS records. Move from human error and XML blindspots to absolute infrastructure-as-a-service certainty.
Complex DNS Edits
Manual TXT record updates across multiple providers with constant syntax error risks.
Constant Monitoring
Reading raw XML reports—or paying for basic dashboard aggregators—to hunt for misconfigurations.
SPF Lookup Limits
Hitting the 10-lookup barrier immediately, causing silent, catastrophic email bounces.
No "Reject" Confidence
Stuck indefinitely in p=none monitoring mode out of fear of blocking legitimate business mail.
1-Click Implementation
A single NS record delegate. You point to us once; we handle thousands of underlying cryptographic records autonomously.
Proactive Rotation
DKIM keys and MTA-STS policies are generated, installed, and rotated proactively to stay ahead of cryptographic decay.
Dynamic SPF Flattening
ExclusiveWe intercept and recursively flatten your complex SPF chains into a single lookup on the fly. Infinite includes.
Guaranteed Enforcement
A safe, mathematically guided path to p=reject. Our algorithms detect safe enforcement states so you can block spoofers without fear.
Have questions? Here's the transparent truth about implementing our governance suite.
Absolutely not. That's exactly why SentraDMARC exists. We start your domain in "Monitoring" mode (p=none) where we act as a silent observer, gathering forensic data on every source sending email on your behalf. We only guide you to "Reject" mode once all your legitimate services (Google Workspace, Mailchimp, Salesforce, etc.) are cryptographically verified and authorized.
We don't lock your infrastructure hostage. If you choose to leave SentraDMARC, you simply remove our CNAMES Pointing from your DNS registrar. Your domain will revert to your manual DNS entries. You won't lose your domain, but you will lose the automated SPF flattening and dynamic active threat response our network provides.
Manually maintaining text records exposes your company to silent failures. You must manually parse XML reports, manually check your SPF 10-lookup limits, and manually rotate MTA-STS policies. SentraDMARC replaces that fragile human workflow with deterministic infrastructure-as-a-service, ensuring your domain logic is evaluated flawlessly milliseconds before an email is delivered.
