Security Considerations

While seesaa.net is an established platform, these capabilities require extra vigilance.

File Hosting

seesaa.net allows users to upload and share files. Any file you download was uploaded by another user—not the platform operator. Scan downloads with antivirus software and only download from sources you trust.

Document Hosting

seesaa.net hosts documents and pages shared via links. Because the domain is trusted, links pass through email spam filters easily. Attackers exploit this to host fake invoices, login pages, or malware download prompts.

User-Generated Content

seesaa.net 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

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

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