Attack Surface
Also known as: Digital attack surface
An attack surface is the total set of points where an attacker could attempt to enter or extract data from a system. Compromised credentials and exposed sessions from infostealers expand the attack surface by creating legitimate-looking entry points.
What is an attack surface?
The attack surface includes every exposed asset, account, and entry point — internet-facing services, employee accounts, third-party integrations, and more. Reducing and monitoring it is a core security objective.
Infostealers and the attack surface
Each set of stolen credentials effectively adds a door to the attack surface — and one that looks legitimate when used. Mapping where your credentials appear in stealer logs reveals attack-surface exposure that traditional asset scanning misses.
VantaPrism maps credential-level exposure — the part of the attack surface created by stolen logins and sessions — so teams can close doors that vulnerability scanners do not see.
