DMARC Monitoring and
Lookalike Domain Protection

Brand Protection + Email Security. Both halves. One platform.

Lock down email authentication so attackers can't send mail as you. Monitor the open web so they can't register lookalike domains either. Two products, sold separately, both starting at $0.

Why both halves

A locked front door does not help if attackers open a fake store next to yours.

DMARC stops attackers from sending mail as you. Lookalike monitoring stops them from registering domains that look like you. Most security tools do one or the other. Real coverage requires both.

Inside-out defense

Direct domain spoofing

The threat: attackers send email using your exact address (ceo@yourbrand.com) because your domain has no DMARC enforcement.

The defense: DMARC, SPF, and DKIM alignment. PhishFence ingests your DMARC reports, flags unauthorized senders, and walks you safely from p=none to p=reject.

Email Security
Outside-in defense

Lookalike typosquatting

The threat: attackers register yourbrand-login.com or yourbrand.io, set up their own DMARC on that domain, and email your customers. Your DMARC cannot touch this. They own a different domain.

The defense: Certificate Transparency monitoring plus registrar sweeps. PhishFence checks hundreds of variants per domain on every scan, scores each by active infrastructure (DNS, SSL, MX, HTTP), captures screenshots to detect content cloning and brand impersonation, and generates registrar takedown reports.

Brand Protection

From detection to takedown, in one workflow.

Find lookalike domains the moment they appear, see what makes each one dangerous, and submit takedowns without leaving the app.

Every variation, automatically

PhishFence checks every way an attacker could twist your domain name: typos, homoglyphs, hyphen insertions, TLD swaps. Thousands of variants on every scan. The squat that other tools miss is usually the one that hits your customers.

Early Warning via CT logsStarter+

PhishFence taps Certificate Transparency feeds so you see new lookalike registrations within minutes of an attacker requesting a TLS certificate, often before the phishing campaign even goes live.

Signal-based risk scoring

Every lookalike is scored by active signals: DNS resolution, SSL certificates, live web content, MX records (mail capability). You see exactly what each domain is doing and which ones to triage first.

Visual proof of cloningPro

Screenshots of every lookalike are captured automatically and tracked over time so you can spot when a dormant domain turns into an active phishing site, plus see what your customers would see if they landed on it.

Takedown reports in minutes

Stop hunting registrar abuse contacts by hand. PhishFence does the RDAP lookup, pre-fills the report, and links directly to the registrar's abuse form. What used to take days takes minutes.

Report to blocklists

One-click submission to Netcraft, plus deep links and pre-filled reports for Google Safe Browsing, Microsoft SmartScreen, PhishTank, and Cloudflare. Track which services you have reported to per alert so nothing gets double-filed or forgotten.

Email Security Free to $399/mo

From visibility to enforcement, in one workflow.

Ingest DMARC reports daily, see exactly who is sending mail as you, find out why anything is failing, then move from p=none to p=reject without breaking legitimate email.

Daily DMARC ingestion

Point your DMARC aggregate (rua) reports at PhishFence and we parse, dedupe, and store every record. Gmail, Microsoft, Yahoo, ProtonMail. All major receivers send reports our way every day, and you get a single pane of glass.

Know who is sending

Every sending IP is enriched with PTR, ASN, and ESP attribution. So instead of 209.85.220.41, you see "Google Workspace" or "SendGrid (acme-corp instance)". Unknowns become obvious immediately.

Posture score per domain

A single posture score across DMARC, SPF, DKIM, MTA-STS, and TLS-RPT. See at a glance which records are weak, which are missing, and which ones attackers love to exploit. Tells you what to fix first.

Per-message forensics

For deep dives on individual failures, PhishFence ingests forensic (ruf) reports too. Full message envelopes, header chains, and ARC results per-incident. The data you need to write a real incident report.

DNS record builders

Skip the DNS record guesswork. Answer a few questions and PhishFence generates the exact DMARC, SPF, and MTA-STS records you need, with safe-rollout guidance so you can move to enforcement without breaking legitimate email.

Enforcement WizardStarter+

PhishFence checks whether every real sender is currently aligning, then walks you from p=none through quarantine to reject at the pace your real traffic supports. No more guessing whether tomorrow's marketing email gets blocked.

Actionable Playbooks

Step-by-step guides for protecting your email, filing abuse reports, getting phishing sites blocked, and registering defensive domains. Written by security practitioners for security practitioners.
