Security Considerations

While zrok.io is an established platform, these capabilities require extra vigilance.

User-Generated Content

zrok.io hosts content created by its users, not the platform operator. Individual posts, profiles, or pages may contain scams, misinformation, or phishing attempts that the platform hasn't yet detected or removed.

Custom Subdomains

zrok.io allows users to create custom addresses like "anything.zrok.io". An address like "paypal-secure.zrok.io" may look official but is actually controlled by whoever registered that subdomain—not NetFoundry.

Remember: The platform itself is established, but even established platforms can be abused.
