Subdomains are often created for temporary use. Many are never properly decommissioned.
Over time, these forgotten assets remain active without monitoring or maintenance.
This makes them attractive targets for attackers.
Common issues include:
• outdated services still running
• subdomains pointing to unused resources
• lack of visibility into existing subdomains
Attackers actively enumerate subdomains to identify weak points.
Every asset connected to your domain increases your attack surface.
