EASM is the continuous mapping, profiling, and discovery of public digital footprint assets (IP addresses, subdomains, SSL certificates, exposed APIs) to evaluate potential vulnerability risk exposures.
HTTP security headers instruct consumer browsers to enforce strict client-side sandboxing, preventing framing hijack, cross-origin scripting injection, and credential leak risks.
By uploading a static text file containing a generated authentication token under the domain's web root, owners authorize our scanner to perform comprehensive ports mapping and directory discovery.
