Email Security Posture Management

Stop email spoofing before it reaches your customers

ESPM monitors DMARC, SPF, and DKIM across every domain you own, turns raw aggregate reports into clear grades and AI-written fixes, and alerts your team the moment something looks wrong.

Send a real email to a one-time address and get back your SPF/DKIM/DMARC results, blacklist status, and a spam score — no account, no credit card. Business email addresses only.

Everything you need to secure your email

One dashboard for DMARC compliance, threat intelligence, and email authentication — no separate tools required.

DMARC, SPF & DKIM grading

Every domain gets a clear A–F grade for its email authentication posture, so you know exactly where you're exposed.

Aggregate report analysis

Upload or auto-ingest DMARC (RUA) reports and see pass/fail breakdowns, sending sources, and alignment failures at a glance.

Automated RUA ingestion

Point your DMARC record at your ESPM reporting address once — reports flow in automatically, no mailbox to babysit.

AI-powered explanations

Claude-powered root-cause explanations turn cryptic authentication failures into plain-English fixes for SOC, dev, and execs alike.

Threat intelligence

Flag suspicious sending IPs, track reputation, and catch spoofing and forwarding attempts before they reach an inbox.

Live DNS tools

Run real-time SPF, DKIM, DMARC, and MX lookups against any domain, right from the dashboard.

Smart alerts

Get notified the moment compliance drops or a new threat appears — routed straight to Slack or PagerDuty.

Integrations

Connect Cloudflare, Slack, PagerDuty, SendGrid, Microsoft 365, and more to fit right into how your team already works.

Enterprise-grade security

Verified email, MFA, encrypted credentials at rest, and scoped API keys for programmatic access.

Anyone can send email pretending to be you

SMTP was never designed to verify who's actually sending a message. Without DMARC enforcement, attackers can forge your domain in the "From" field and send phishing emails that pass every visual check your customers know to look for — right down to your logo and tone of voice.

  • Every unauthenticated domain is a target for business email compromise and invoice fraud.
  • Without visibility into DMARC reports, you have no idea it's happening until a customer complains.
  • Moving from p=none to p=reject blind risks blocking your own legitimate mail.

With ESPM

See every sending source for your domain, legitimate or not, in one place.
Get a clear grade and a prioritized, AI-explained path from p=none to p=reject.
Get alerted the moment a new, unrecognized IP starts sending as you.

Fits right into your stack

Up and running in minutes

1

Add your domain

Connect via Cloudflare or add it manually — verification takes one DNS TXT record.

2

Point your DMARC record at ESPM

Add the generated rua= address to your DMARC TXT record so receivers report back to us.

3

Get graded, alerted, and explained

Reports are parsed automatically into a real-time grade, trend charts, and AI-written fixes.

Frequently asked questions

DMARC (Domain-based Message Authentication, Reporting & Conformance) is the DNS record that tells receiving mail servers what to do with email claiming to be from your domain — and tells them to report back to you about it. Without it, anyone can spoof your domain to send phishing emails that look completely legitimate.
