Digital Footprint Analysis

Digital Footprint Analysis, sometimes called External Attack Surface Management (EASM), starts from the premise that most organizations do not actually know the full extent of what they have exposed to the internet. Subsidiaries acquired years ago, marketing microsites spun up by a contractor, forgotten development subdomains, and cloud storage buckets provisioned outside change control all expand the real attack surface well beyond what any internal asset inventory captures. The service maps this surface from the outside, the same vantage point an attacker starts from, using passive techniques — certificate transparency logs, WHOIS and ASN registration data, passive DNS records, and public code repositories — to discover candidate assets without ever touching the target directly.

Discovery alone is not enough; every candidate asset must be attributed back to the organization with reasonable confidence before it is actionable, distinguishing genuinely owned infrastructure from coincidentally similar third-party assets. Confirmed assets are then assessed for exposed services, outdated software versions, missing security headers, and misconfigurations, and cross-referenced against credential-leak and dark web monitoring to surface exposed employee or customer data tied back to the organization's domains. Because the footprint changes continuously — new subdomains appear, certificates expire, contractors spin up new infrastructure — this is run as an ongoing process aligned with the Continuous Threat Exposure Management (CTEM) model rather than a single point-in-time report.
