In-depth guides to understand every finding DomainRisk.io surfaces - what it means, why it matters and exactly how to fix it.

An email lands in your customer's inbox, sent from your exact domain, with your visual identity — but you never sent it. That is domain spoofing. No network configuration prevents it by default. Here is how attackers pull it off, what it costs, and how to close every vector.
By default, DNS has no authentication — anyone who can intercept or poison a response can silently redirect your users to a malicious server. DNSSEC closes that gap with cryptographic signatures on every record. Here is how the chain of trust works and how to enable it.
BIMI is the only email standard that lets you display a verified brand logo directly in the inbox — combining anti-phishing protection with a measurable trust signal. Here is how the technical chain works, when you need a VMC, and how to implement it step by step.
Finding lists are useful — but they are not decisions. A domain security score collapses dozens of signals into a single number with clear thresholds. Here is how it is built, what each band means, and why a guardrail prevents a 90/100 from hiding a critical flaw.
Registration age, registrar reputation, WHOIS redaction, DNS configuration, SSL metadata, typosquatting distance, subdomain proliferation — none is sufficient alone. Here is how to combine all seven signals into a composite risk verdict.
Without DKIM, your emails carry no cryptographic proof of origin — and your DMARC policy rests on SPF alone, which breaks under forwarding. Learn how DKIM works, how to configure it for every sending service, and how to rotate keys safely.
A missing SPF record leaves your domain open to spoofing. A broken one silently blocks your own email. Learn how SPF works, what every mechanism does, and how to avoid the 10-lookup trap.
Every subdomain you ever created left a DNS record. Every cloud service you ever cancelled left a CNAME pointing nowhere. Attackers scan for these orphaned records systematically — here is how to find them first.
By default, any certificate authority in the world can issue an SSL certificate for your domain. A single DNS record — the CAA record — restricts that authority to a whitelist you control.
Every article in this knowledge base maps to a real finding DomainRisk.io can detect automatically. Add your domain and get a full WHOIS, DNS, SSL and email-auth report in under 60 seconds.
