Subdomain Cloud Hosting
End EASM Fatigue: Move from Chaotic Subdomain Inventory to Risk-Based Prioritization
The relentless sprawl of Shadow IT and the complexity of multi-cloud vendor environments have created a critical, high-reward attack vector: the Dangling DNS vulnerability. Attackers are actively scanning for decommissioned cloud assets that still retain a legitimate CNAME record, exploiting this inherited trust to hijack your brand and launch massive phishing campaigns. ThreatNG’s enhanced Subdomain Cloud Hosting capability transforms this chaotic external threat landscape into decisive security insight by moving beyond mere inventory to provide the industry’s only Specific Validation Check that confirms real-world exploitability, ensuring your team focuses resources only on the threats that matter.
Reduce Risk, Enhance Security, Gain Control: ThreatNG Subdomain Intelligence Maps Your Subdomain Cloud Ecosystem
Reduce Risk
By identifying all subdomains and their hosting locations, you gain a comprehensive view of your organization's external attack surface. This allows you to pinpoint potential vulnerabilities and prioritize security efforts, reducing the risk of breaches and data exposure.
Understanding your reliance on third-party cloud vendors helps you assess and manage fourth-party risks, ensuring compliance and minimizing supply chain vulnerabilities.
Enhance Security
Knowing which assets reside on public clouds (AWS, Azure, GCP) enables you to implement appropriate Cloud Security Posture Management (CSPM) solutions. This ensures your cloud configurations adhere to best practices and regulatory standards.
For assets hosted by other cloud vendors, you can leverage SaaS Security Posture Management (SSPM) tools to maintain strong security controls and data protection measures.
Gain Control
ThreatNG provides a clear picture of your organization's digital presence, empowering you to make informed decisions about resource allocation and security investments.
With a comprehensive understanding of your cloud ecosystem, you can optimize cloud usage, improve efficiency, and strengthen your overall security posture.
End the EASM Guesswork and Achieve Certainty
Stop Cataloging Chaos: Gain Decisive, Risk-Based Prioritization
Your security resources cannot be wasted navigating exhaustive, unprioritized lists of potential threats. ThreatNG eliminates this EASM fatigue by performing a proprietary Specific Validation Check to confirm whether a CNAME pointing to an external service on our Vendor List is truly inactive or unclaimed. This immediate confirmation of the "dangling DNS" state converts ambiguous data into prioritized, actionable intelligence, ensuring time is spent mitigating high-risk assets rather than solving non-existent issues. Therefore, you know exactly where the real threats lie.
Protect Brand Value and Avoid Catastrophic Loss
Cost Avoidance is Compliance: Protecting Against the $4.88M Global Breach Cost
A successful Subdomain Takeover immediately weaponizes your brand's reputation for phishing and fraud, leading directly to financial and market consequences. This solution is essential insurance against documented risks: the average cost of a breach is $4.88 million, and studies confirm that 81% of consumers may cease engaging with a brand after an incident. ThreatNG protects your Brand Damage Susceptibility Security Rating by mapping external, unmanaged configurations—a common source of audit failure—to critical GRC frameworks, including GDPR, HIPAA, and PCI DSS. This provides auditable evidence that your organization proactively controls the Decommissioned Cloud Resource Liability and justifies your strategic security spend to the board.
Outpace Shadow IT with the External Adversary View
Defeat Organizational Sprawl: Continuous Monitoring for All External Vendors
The CISO cannot control what the organization cannot see. Development, Marketing, and Operations teams are constantly integrating new cloud and SaaS platforms (AWS, Heroku, Shopify, Zendesk, etc.), which creates Shadow IT blind spots that attackers target. ThreatNG operates from the External Adversary View, continuously performing unauthenticated discovery across a broad range of specialized vendors to ensure comprehensive visibility into your digital footprint. ThreatNG is your vigilant eye, empowering your team to detect and neutralize the Inherited Trust Attack before the opportunistic attacker can claim a forgotten asset.
Illuminate Your Cloud Presence: ThreatNG Exposes Hidden Risks and Opportunities Across All Cloud Platforms
Gain complete visibility into your organization's external attack surface with ThreatNG's Subdomain Intelligence.

Frequently Asked Questions (FAQ): Cloud-Based Subdomain Intelligence
The Foundational Challenge: Granular Cloud & SaaS Visibility
-
The cornerstone of effective External Attack Surface Management (EASM) is moving beyond generic IP identification to precise platform attribution. ThreatNG achieves this foundational step using a purely external, unauthenticated process:
External Discovery and DNS Enumeration: The system first identifies all associated subdomains of the organization and then performs DNS enumeration to locate CNAME records. These records signify a delegation of trust from your domain to an external third-party service.
Comprehensive Vendor Cross-Referencing: The external service hostname is then systematically cross-referenced against ThreatNG’s exhaustive, proprietary Vendor List (DarCache). This list provides granular classification across thousands of external technologies, ensuring every element of your Shadow IT footprint is accounted for.
This process immediately maps external assets to specific platforms. The Vendor List includes services categorized across numerous domains :
Cloud & Infrastructure: Including granular breakdowns for Storage & CDN (like AWS/S3, Cloudfront, Microsoft Azure) and PaaS & Serverless (like ElasticBeanstalk, Heroku, Vercel).
Development & DevOps: Covering Version Control (like Bitbucket, Github), API Management, and Developer Tools.
Website & Content: Including Storefront Platforms (like Bigcartel, Shopify, Zendesk), Content Management Systems (like Wordpress, Pantheon), and Visual Designers (like Tilda, Webflow).
Customer Engagement: Ranging from Service Desks (like Freshdesk, Help Scout, Zendesk) to Live Chat/Feedback systems.
Marketing & Sales: Including Page Builders (like Instapage, Unbounce) and CRM/Email services (like ActiveCampaign, Hubspot).

For the CISO, platform identification converts raw inventory into a strategic risk assessment. Knowing the host platform is essential for three reasons:
Targeted Remediation: It allows your team to instantly identify the operational owner and apply the correct, platform-specific remediation workflow. Different cloud platforms have distinct asset reclamation and configuration procedures.
Accurate Risk Profiling: Different platforms present different inherent security risks and Subdomain Takeover vectors. A misconfigured AWS S3 bucket requires a different validation and remediation strategy than an unclaimed storefront, ensuring security teams can allocate resources correctly.
Closing Shadow IT Blind Spots: As the external attack surface includes thousands of potentially untracked third-party applications, comprehensive mapping ensures that even niche platforms used for temporary projects are continuously monitored for misconfigurations that attackers rely on.
Decisive Risk Validation: Subdomain Takeover Susceptibility
-
The Dangling DNS vulnerability is the critical configuration error that enables Subdomain Takeover. It arises from organizational complexity and poor cleanup—when a development or marketing team deletes a temporary cloud resource to save costs, but forgets to remove the corresponding CNAME record from the company’s DNS zone.
The record is left "dangling," pointing to a resource that is now inactive or unclaimed on the third-party platform. This is highly exploitable because an attacker can simply register an asset with the same name on that platform, instantly inheriting the brand’s domain name and the inherited trust associated with it. This low-effort attack enables adversaries to launch devastating phishing campaigns and distribute malware under the guise of your legitimate corporate domain.
-
ThreatNG eliminates the paralyzing ambiguity that characterizes traditional external scanning by performing a Specific Validation Check. This feature provides Decisive Security Insight, moving beyond flagging every CNAME as a potential risk :
After finding a CNAME record and successfully identifying its external vendor (as outlined in Q1), ThreatNG performs a dedicated validation.
This check determines whether the CNAME currently points to a resource that is definitively inactive or unclaimed on that vendor's platform.
This final, rigorous step confirms the "dangling DNS" state, ensuring your team focuses resources only on verified, critical, exploitable threats rather than wasting time on low-priority or non-existent issues. This high-confidence validation is essential for effective Risk-Based Prioritization.
CISO Strategic Value: Risk Reduction and Control
-
Failure to maintain continuous control over external, misconfigured assets, such as dangling DNS entries, is a demonstrable regulatory liability. The exploitation of such a flaw can result in data exposure and severe penalties.
ThreatNG provides an External GRC Assessment that functions as a continuous, outside-in evaluation of your compliance posture. It maps exposed assets and critical vulnerabilities, like Subdomain Takeover Susceptibility, directly to required controls within critical frameworks: PCI DSS, HIPAA, GDPR, NIST CSF, and POPIA. By proactively providing this auditable evidence of external configuration control, you strengthen your overall GRC standing and mitigate the risk of regulatory fines.
-
This capability delivers Relief and Certainty by resolving the core CISO challenge: complexity in risk prioritization.
The cost of inaction is staggering, approaching the global average breach cost of $4.88 million. When your EASM results in chaotic inventory, your team is effectively forced to waste resources on non-critical issues. ThreatNG’s decisive validation capability solves this by immediately prioritizing the high-impact threats—the confirmed, exploitable assets. This accelerated focus on validated, critical threats improves incident response and leads to a measurable, rapid reduction of your external attack surface, ensuring resources are allocated effectively to defend against the most immediate financial and reputational losses.
