In the digital landscape, subdomains often act as hidden annexes. They are the forgotten staging environments, deprecated marketing sites, and rogue developer APIs that exist entirely outside the view of your central security team. If these pathways are abandoned and left off official IT blueprints, they bypass all primary security checkpoints, becoming the exact routes intruders use to compromise your entire facility.

Legacy internal security tools and scanners require restrictive seed data, administrative credentials, or heavy software agents to map an attack surface. This inherently limits their visibility to the infrastructure your IT team already knows about. If your IT team does not know that a rogue developer API exists, a legacy tool that requires an internal agent will never find it.

ThreatNG takes a completely frictionless, zero-connector approach. Operating as an unauthenticated external Scout, it shatters the blind spots of legacy tools by automatically detecting and inventorying HTTP, HTTPS, and Kubernetes API endpoints across all domains and subdomains from the outside looking in. It actively probes and continuously monitors HTTP responses and unexpected redirects to uncover structural faults that internal checklists miss.

A Subdomain Takeover occurs when an organization abandons a cloud resource or third-party service but forgets to delete the DNS record pointing to it. ThreatNG’s DarChain Methodology maps exactly how this minor IT oversight chains into a catastrophic business consequence:

• The Exposure: ThreatNG discovers a forgotten customer support subdomain that points to a third-party vendor (such as Zendesk) your company no longer uses.

• The Exploit: Because the DNS record is left dangling, an attacker registers the abandoned vendor namespace, executes a subdomain takeover, and sets up an MX record to spoof your domain—bypassing your DMARC and SPF validation.

• The Consequence: The adversary launches a massive Business Email Compromise (BEC) and phishing campaign from your trusted subdomain, destroying brand equity and resulting in severe financial fraud.

Yes. ThreatNG reveals exactly where subdomains are hosted, uncovering environments on major public clouds (Amazon Web Services, Microsoft Azure, Google Cloud Platform) and third-party vendors (Zendesk, HubSpot, Heroku). This maps subdomain hosting locations to identify shadow cloud infrastructure and unmanaged SaaS platforms without requiring access to internal APIs.

Managing external infrastructure is often plagued by operational guesswork. ThreatNG replaces this with a deterministic proof by identifying the exact IP addresses, DNS records, and active ports associated with a subdomain. This delivers Contextual Certainty and Legal-Grade Attribution, mathematically proving ownership and highlighting the exact state of your external exposure.

When ThreatNG identifies malicious redirects or potential phishing sites mimicking your legitimate subdomains, it does not just send a generic alert. It compiles this deterministic intelligence into Forensic Evidence Packages. You can hand this business-aligned proof directly to your legal counsel or third-party takedown services, equipping them to execute a frictionless, guaranteed strike against the adversary's infrastructure.

Subdomain Intelligence is the ultimate structural inspection tool for M&A. Before a deal closes, ThreatNG maps the complete, unvarnished digital footprint of an acquisition target, exposing hidden technical debt, unsecured APIs, and forgotten infrastructure. This ensures that you do not inherit critical vulnerabilities and shadow IT from the acquired entity.

Absolutely. ThreatNG aggressively hunts for exposed infrastructure, leveraging specialized frameworks to pinpoint exposed AI development environments (such as Langflow or n8n) and unsecured web applications. This allows governance teams to rein in Shadow AI before it exposes sensitive corporate data.
