Security Overview

Link Astra Limited operates a secure AI inference infrastructure platform designed to protect customer data, ensure system reliability, and maintain service integrity.

We adopt a defense-in-depth security strategy covering infrastructure, data, access control, and operational security.

1. Infrastructure Security

Our AI inference infrastructure is deployed on secure GPU computing environments. We implement:

TLS encryption in transit
Encryption at rest
DDoS protection and traffic scrubbing
Regular security updates and patch management

2. API Security

Our API is designed with security-first principles:

API key authentication
Request rate limiting
Input validation and sanitization
Abuse detection and alerting

3. Data Security

Data processing follows minimization principles:

Input data processed in real-time, not stored long-term
Output data not used for model training
Log data encrypted at rest
Data retention follows minimum periods

4. Access Control

Role-based access control
Principle of least privilege
Additional authentication for high-risk operations
Regular permission audits

5. Compliance

We continuously track and follow applicable data protection regulations, regularly assessing security policy effectiveness.

Our security controls are designed to support the data security principle under the Hong Kong Personal Data (Privacy) Ordinance.
