What is a Namespace?

Your company's complete presence across the internet

In Simple Terms

A namespace is everything on the internet that represents your organization—all your domain names, subdomains, websites, email systems, and digital services that share your company's identity.

Think of it like your company's "digital real estate"—all the addresses and properties you own or control across the internet.

What's Part of Your Namespace?

Primary Domains

Your main company domains like example.com, example.co.uk, example.io—the top-level names that identify your organization.

Subdomains

All the variations under your domains: www.example.com, api.example.com, mail.example.com, staging.example.com, and hundreds more you may not even know about.

Certificates & Security

TLS/SSL certificates protecting your domains and subdomains, ensuring secure HTTPS connections for your users.

Email Infrastructure

Email domains, MX records, SPF/DMARC/DKIM configurations that let you send and receive email from @example.com addresses.

Brand Variants

Related domains you own for brand protection, regional variants, product lines, or acquisitions—like example.net, example-shop.com, oldcompany.com.

Shadow IT & Forgotten Assets

Test sites, old staging environments, third-party integrations, SaaS subdomains, and other assets you may have lost track of but still operate under your namespace.

Real-World Example

Let's say your company is "Acme Corp" and you own acme.com. Your namespace includes:

Production Sites
  • • www.acme.com
  • • shop.acme.com
  • • support.acme.com
  • • blog.acme.com
Email & Services
  • • mail.acme.com
  • • @acme.com addresses
  • • api.acme.com
  • • cdn.acme.com
Internal & Dev
  • • intranet.acme.com
  • • staging.acme.com
  • • dev.acme.com
  • • vpn.acme.com
Legacy & Brand
  • • acme.co.uk (UK site)
  • • acme.io (redirect)
  • • oldcompany.com (acquired)
  • • acmeapp.com (product)

All of these together form Acme Corp's namespace. NodeZro discovers all of this automatically, including assets you may have forgotten.

Why Your Namespace Matters

Security

Every subdomain is a potential attack surface. Forgotten or misconfigured assets in your namespace can be exploited by attackers to compromise your organization.

Compliance

Auditors want to know: "What data is out there under your domain?" If you can't enumerate your namespace, you can't prove compliance with GDPR, SOC 2, or other regulations.

Brand Protection

Typosquatters and phishers register domains similar to yours (like "acme-support.com" or "acme-login.com") to trick your customers. Monitoring your namespace helps you detect and take down brand abuse.

Operational Visibility

You can't manage what you can't see. Without a comprehensive inventory of your namespace, you can't track certificate expirations, DNS misconfigurations, or infrastructure dependencies.

Cost Control

Organizations often pay for domains, certificates, and hosting for assets they no longer use. A clear namespace inventory helps identify waste and reduce spending.

Common Namespace Problems

Shadow IT

Developers spin up test sites or SaaS tools that create subdomains under your namespace. These get forgotten but remain accessible—often with weak security or sensitive data.

Dangling DNS

DNS records pointing to infrastructure you've decommissioned (old S3 buckets, deleted cloud servers). Attackers can claim these resources and host malicious content on YOUR domain.

Expired Certificates

TLS/SSL certificates protecting subdomains expire without warning because no one tracked them. Sites go down, users see security warnings, and trust erodes.

Inconsistent Governance

Different teams manage different parts of the namespace with different standards. Result: some assets have MFA, monitoring, and backups—others have none.

How NodeZro's Namespace Command Center Helps

Autonomous Discovery

NCC discovers your external namespace automatically—no spreadsheets, no manual audits, no missed assets. Just submit your primary domains and get a comprehensive inventory in less than 24 hours.

Continuous Monitoring

Your namespace changes constantly (new subdomains, expiring certs, DNS updates). NCC monitors continuously and alerts you to changes, gaps, and risks.

Risk Scoring

Every asset in your namespace is scored for exploitability, business impact, and SPOF exposure so you know what to fix first.

Policy Enforcement

Define governance policies (e.g., "all production domains must have valid TLS certificates") and NCC automatically validates compliance across your external namespace.
