Asset Discovery & Reconnaissance

You can't protect what you don't know exists. We map your external attack surface just like an attacker would, continuously discovering subdomains, open ports, and technologies to find weak spots before they do.

A Complete Attacker's-Eye View

Our engine delivers a detailed intelligence report on every asset. Here's the kind of critical information you'll receive:

Multi-Vector Subdomain Enumeration

We combine passive discovery and active brute-forcing to find forgotten dev, staging, and API endpoints that are often unpatched and vulnerable.

Uncover High-Risk Assets Like:
api-v1.your-domain.com dev-jenkins.your-domain.com backup.your-domain.com old-portal.your-domain.com

Open Port & Service Analysis

We scan for all open ports to identify potential entry points and fingerprint the services running on them, pinpointing exploitable and outdated software.

Identify Exposed Services:
Web Servers (HTTP/S) Mail Servers (SMTP) Remote Access (SSH) Databases (MySQL)

In-Depth DNS Intelligence

Your DNS records are a public roadmap. We analyze them to map your infrastructure, validate critical security policies, and prevent threats like email spoofing.

  • NS Records: Uncover your DNS provider (e.g., Cloudflare, AWS Route 53).
  • MX Records: Identify the organization's email provider (e.g., Google Workspace, Microsoft 365).
  • Email Security: Verify the enforcement of SPF, DKIM, and DMARC policies.

Technology Stack Fingerprinting

Understanding your stack is key to threat modeling. We identify web servers, frameworks, and third-party services to reveal your software supply chain.

Identify Technologies Like:
AWS Nginx React WordPress

Our Discovery Engine: Passive Intel + Active Probing

Our reconnaissance process mirrors an attacker's methodology by combining two powerful techniques for maximum coverage:

  1. 1
    Passive Reconnaissance

    We start by silently gathering intelligence from public sources like Certificate Transparency logs to build an initial map of your assets without sending a single packet to your servers.

  2. 2
    Active Enumeration

    Next, we launch a safe, concurrent brute-force enumeration against your domain using a curated wordlist to uncover unlinked or hidden subdomains that passive methods miss.

Benefits of Our Methodology

Maximum Coverage

Combining passive and active techniques ensures we find assets that other tools might miss.

High Signal, Low Noise

Every discovered asset is validated, giving you an accurate and actionable inventory.

Safe for Production

Our passive-first approach and controlled active probing are designed to be non-disruptive.
