What is SurfaceDiff?

SurfaceDiff is a continuous external attack surface monitoring platform for domains you own or are authorized to manage. It observes publicly exposed infrastructure, stores each scan as a snapshot, and shows what changed between scans.

Key capabilities:

Baseline scan of a domain's publicly exposed assets
Scheduled monitoring and automatic change detection
Discovery and tracking of subdomains, DNS records, open ports, TLS certificates and web services
Incidents with supporting evidence and change history
Drift analysis and comparison of historical snapshots
Evidence Center with signed PDF reports documenting the observed state
Domain ownership verification via DNS record or server file

SurfaceDiff is not a conventional vulnerability scanner. Its primary purpose is to help infrastructure, DevOps and security teams identify changes in public exposure and determine whether those changes were expected and authorized.

The Free Plan includes one verified domain and one scheduled scan per day with no time limit. No payment card is required. Users create an account, add a domain, verify ownership and run the first scan to establish the initial baseline.
