Attack Surface Mapping
Discover every asset, subdomain, and entry point across your external perimeter. See what attackers see before they do.
How it works
Subdomain Enumeration
Multi-source discovery combining Certificate Transparency logs, passive DNS databases, and search engine analysis to find every subdomain.
Asset Correlation
Automatically link discovered subdomains, IPs, and services into a unified asset inventory with relationship mapping.
Shadow IT Detection
Identify forgotten dev environments, decommissioned servers, and unauthorized cloud instances that expand your attack surface.
Your complete external footprint
The attack surface expands organically through cloud migrations, DevOps automation, mergers and acquisitions, and decentralized IT procurement. Deft tracks this growth continuously.
Our multi-source enumeration strategy combines Certificate Transparency logs, passive DNS databases, search engine dorking, and DNS zone analysis to build a comprehensive map of your external presence.
Each discovered subdomain undergoes the same comprehensive port scanning and service identification process, ensuring no asset goes unmonitored.
