DOMINION FORTRESS / Attack Surface
See your external attack surface before someone else does.
An external attack surface assessment maps publicly discoverable domains, subdomains, services, applications and technology signals so your team can understand what is exposed.

Domains and DNS
Public DNS records and related domain infrastructure within the agreed scope.
Web applications
Publicly reachable sites and applications and their visible technology signals.
Services and exposure
Externally discoverable services and configuration signals that warrant review.
Email security
SPF, DMARC and related public mail-domain signals.
Why start externally?
Your public attack surface changes as teams launch domains, SaaS products, cloud services and marketing sites. An external view helps identify assets your internal inventory may not capture.
Assessment boundary
Initial public checks are passive. Intrusive testing is never implied and requires explicit authorization and defined scope.
