Data stays in Thailand

Customer data stays in Thailand, and AI models run on our GPU servers in a Thai data center. The data center network denies outbound connections by default.

Organisations are isolated

Every customer-owned table records its owning organisation and carries a row-level policy in the database. The application connects with an account that cannot bypass that policy.

No leaks, not even hints

A hidden document and a missing document get the identical response. Permission filters sit inside the query, never applied afterwards.

Hash-chained audit log

Append-only, with SHA-256 hashes linking entries into a chain per organisation. The application account may only insert and read. A verification page recomputes the chain and shows its integrity. No passwords, tokens or document content are stored in the log.

Identity and sessions

Accounts are by invitation only. Access tokens last 15 minutes, and sessions are revoked on logout or suspension. TLS is used on every connection.

Uploads are checked

File types are sniffed from content, sizes are limited and files are scanned for malware before processing.

Certifications and standards

We do not currently claim any certification or external audit. If your organisation needs technical detail or the current status of a specific control, please contact us.
