Stop Phishing Attacks
at the Source
A new phishing site goes live every 20 seconds. Your email gateway catches some. Training catches some more. But what about the lookalike domains targeting your customers on channels you don't control?
DefendDomain detects and shuts down impersonating domains, fake sites, and rogue SSL certificates before they reach a single victim.

Real threats targeting your domainExpert consultation, not a sales pitchNo obligation
Phishing costs businesses $4.88 million per breach on average. Even small organisations lose $120,000–$1.6 million per incident.
We catch the attack infrastructure before it's ever used.
DefendDomain monitors the domains, websites, and certificates that attackers register to impersonate your brand and alerts you the moment they appear, often before a single phishing email is sent.
Understanding the threat
What are Phishing Attacks?
Phishing is a cyber attack where adversaries impersonate a trusted entity to deceive victims into revealing sensitive information, transferring funds, or installing malware.
External (Spoofing)
Attackers spoof your exact email domain to attack customers or employees. This happens when DMARC/SPF records are missing or misconfigured.
We don't help with this (handled by DMARC).
Internal (Inbound)
Your company receives phishing emails from external adversaries targeting your employees directly.
Handled by existing email gateways/spam filters.
External & Internal
Attackers register lookalike domains (e.g., your-company.co) to bypass gateways and trick employees, customers, or suppliers.
We detect if these lookalike domains have registered working email (MX) and if they have a live site.

Threats arrive pre-triaged with WHOIS data and risk scores. Focus only on what actually needs action.
Compliance & GRC Teams
Produce audit-ready evidence of external threats
Immutable audit trail of every domain threat. Generate ISO 27001 and NIST CSF reports in one click.
SOC & Incident Response
Pre-triaged domain threats in existing workflows
Alerts flow into Slack, Teams, Splunk, or Sentinel with full evidence packages attached.
Why Your Current Controls Leave Gaps
Determined attackers find the blindspots in even well-configured security stacks. Here's what we hear most often — and why it matters.
"We have DMARC and SPF"
DMARC only protects emails sent from your exact domain. If an attacker registers your-company.co or yourcompany-login.com, DMARC has zero visibility. Lookalike domain phishing bypasses email authentication entirely.
Why DMARC alone isn't enough"We use an email gateway"
Email gateways filter inbound threats to your employees but can't stop phishing that targets your customers via personal email, SMS, social media, or search ads. The attack surface extends far beyond your corporate inbox.
Gaps in gateway-only protection"Our employees are trained"
With over 90% of phishing sites now using HTTPS, the padlock icon is meaningless as a trust signal. Sophisticated lookalike domains fool even security-aware users, especially when they're busy or on mobile.
Why training needs a safety net"We already bought similar domains"
There are virtually infinite permutations across 200+ TLDs. You can't buy them all. Attackers only need one you missed, like a country-code TLD or keyword variant. Defensive registration alone is a losing strategy.
Moving from reactive to proactiveFour layers of protection
How DefendDomain Stops Phishing
Every attack relies on infrastructure — a domain, a certificate, a cloned site. We detect each one the moment it appears.
Layer 1
Domain Monitoring
Proactively monitors for lookalike domains that could be used to impersonate your brand. Our AI generates thousands of domain variations including typos, homoglyphs, and keyword combinations, then continuously scans for registrations.
- Detects typosquatting and phishing domains
- Monitors domain registrations in real-time
- AI-powered threat scoring and prioritization
- Automated evidence collection for takedowns
