Frequently asked questions
What is DomainGuard?
DomainGuard is a domain impersonation monitoring service for small businesses. It watches Certificate Transparency logs for rogue certificates issued in your name, scans thousands of typosquat and lookalike domains targeting your brand, and checks your CAA DNS posture — alerting you the moment anyone impersonates your domain.
What is domain impersonation?
Domain impersonation is when attackers register lookalike domains (typosquats like yourbrand-login.com) or obtain certificates for your name, then use them to phish your customers. In March 2026, one extra letter in a lookalike domain cost the town of Surfside Beach, SC $545,598 — documented by the Cloud Security Alliance.
How does DomainGuard detect impersonation?
Three ways: (1) we poll Certificate Transparency logs so you're alerted the moment any certificate is issued for your domain — the same technique Google publicly recommends; (2) we generate thousands of typosquat permutations and check which are actually registered; (3) we check your CAA DNS posture and scan registered lookalikes for phishing-kit indicators.
What is a CAA record and why does it matter?
A CAA DNS record tells the world which certificate authorities are allowed to issue certificates for your domain. Without one, any CA can issue. Publishing two lines of DNS stops most rogue issuance — we check yours and give you the exact records to add.
What do I do when DomainGuard finds a phishing domain?
Every finding ships with a takedown packet: registrar abuse contact, hosting provider abuse, Google Safe Browsing and Microsoft SmartScreen report links, PhishTank, and IC3. Follow the packet and most phishing domains come down in hours to days.
Is the free report really free?
Yes. For $0/mo you get a one-time impersonation exposure report for one domain: certificate history, registered lookalikes found, and your CAA posture. No credit card. Continuous monitoring with instant alerts is Pro ($29/mo).
What if I want a refund?
One-click refund, no questions asked. Reply to any email or use the billing page within 30 days: your license key is revoked and your payment refunded the same day.
