Your DNS is the foundation everything else runs on — email, websites, APIs, internal tools. When something goes wrong at the DNS level, the impact is immediate and often invisible until it’s too late. DNSVigil gives you complete visibility into your domain infrastructure so you can catch misconfigurations, forgotten subdomains, and unauthorized changes before they become security incidents.

Find Every Subdomain You Own
Most organizations have more subdomains than they realize — leftover staging environments, old marketing campaigns, abandoned partner integrations. Each forgotten subdomain with an active DNS record is a takeover risk. We find them all.

✔ Takeover vulnerability detection
✔ Orphaned and forgotten subdomain flagging
✔ Shadow IT and test environment identification
✔ New and removed subdomain tracking over time
Email DNS Protection
If your SPF, DKIM, or DMARC records are wrong — or missing — anyone can send emails pretending to be you. We validate your email DNS configuration and watch for unauthorized changes that could open the door to spoofing attacks.
✔ SPF record validation and monitoring
✔ DKIM key presence and correctness checks
✔ DMARC policy analysis
✔ Unauthorized change alerts
✔ Step-by-step remediation guidance
