DomainScan vs Agari (Fortra) — DMARC & Brand Protection Comparison

Agari (now Fortra Email Security after the 2021 acquisition) is the enterprise DMARC and brand-impersonation defense platform used by governments and Fortune 100 companies. DomainScan gives you DMARC monitoring plus wider domain intelligence at self-serve pricing.

Verdict
Agari / Fortra wins on brand-impersonation defense at enterprise scale, embedded threat intelligence, and DoD-level customer references. DomainScan wins on price accessibility, wider domain-security coverage, AI-generated remediation, and MCP-native API — the stronger fit for teams outside the F100.

Agari (acquired by Fortra in 2021, folded into Fortra Email Security) is one of the two enterprise DMARC platforms — the other being Valimail — that dominate F100 and government deployments. Their brand-impersonation defense product is the reason a lot of household-name banks stopped losing customers to phishing campaigns.

The catch is the enterprise-sales motion: quotes, procurement, six-figure ACVs, and an assumption that DMARC and BEC defense are your only concern. If they are, Agari is world-class. If they aren’t — if you also need DNS monitoring, SSL lifecycle tracking, subdomain-takeover audits, and blacklist visibility — DomainScan bundles all of that at self-serve pricing.

Where Agari (Fortra) wins

  • Brand impersonation defense. Their identity graph tracks look-alike domains and impersonation attempts across the wider internet — genuinely industry-leading for regulated brands.
  • BEC protection. Enterprise threat models covered end-to-end: executive impersonation, vendor fraud, invoice manipulation.
  • DoD / F100 references. Their customer list is the reason they command enterprise pricing.
  • Managed service option. Full-service DMARC deployment with named engineers.

Where DomainScan wins

  • Coverage breadth. DMARC is one signal. DomainScan tracks DNS records, SSL cert lifecycle, WHOIS changes, blacklist status, security headers, and subdomain-takeover risk — every one of them a real vector.
  • Self-serve access. Sign up, add a domain, see results in seconds. No procurement, no quotes.
  • Prism AI remediation. Every finding comes with a paste-ready fix.
  • MCP integration. Any AI agent can call DomainScan directly.
  • Price accessibility. $9/month starter. $99/month for MSP-scale.

Bottom line

If you’re a regulated enterprise — bank, insurer, healthcare system, critical infrastructure operator — with a mandate to prevent brand impersonation and BEC and are already budgeting six figures for email security, Agari / Fortra is a defensible choice. For everyone else, DomainScan gives you the DMARC signal plus every other domain-security signal without the enterprise sales cycle.
