DISCOVERY OF ATTACK SURFACE

The official inventory is not your attack surface. Preliminary analysis shows what is outside of it.

Subdomain enumeration only shows what you already expect to find. The ML-Powered Discovery by CSURFACE maps what is outside the inventory—subsidiaries, related organizations, shadow IT, and forgotten assets. Request a free preliminary analysis and see your company's real attack surface.

WHAT DISCOVERY REVEALS

The surface that subdomain enumeration does not reach

Listing subdomains of a known domain is the starting point — not the end result. The preliminary analysis starts from your company name and expands the discovery to everything connected to it, even outside the official inventory.

Forgotten assets — legacy environments, old domains, and published hosts without follow-up.
Shadow IT — cloud services and applications uploaded by teams without going through IT or security.
Subsidiaries and related organizations — assets of group companies, brands, and acquisitions that expand your exposure.
Assets outside the inventory — domains, certificates, and infrastructure not listed in any spreadsheet or CMDB.

How it works

1 · You fill in the data next to you — the discovery starts from your entire company, starting with a domain.
2 · CSURFACE correlates public signals with ML-Powered Discovery to find what is outside the inventory. Everything passive, nothing installed.
3 · You receive the real attack surface portrait by email within 48 business hours.

No cost, no commercial commitment. The analysis is performed exclusively upon acceptance of the Terms and declaration of ownership of assets — conditions that ensure responsible use of the process.
