🔒 Enterprise Security Architecture

KKCSI Security & Infrastructure

Version 2.4 · OVH Singapore Tier-3 Infrastructure & Multi-Tenant Defense

Security, tenant data confidentiality, and infrastructure resilience are foundational to the KKCSI AI Assistant SaaS platform. We employ a defense-in-depth architecture across application logic, database partitions, and network routing.

1. Security Architecture Pillars

🛡️ Multi-Tenant Isolation

Strict organizational boundary separation. PostgreSQL row-level partitions and vector namespaces ensure data never leaks across tenant accounts.

🔐 End-to-End Encryption

TLS 1.3 encryption for all data in transit. API tokens, WhatsApp secrets, and database credentials are encrypted at rest with AES-256 GCM.

🇸🇬 Tier-3 Singapore Hosting

Enterprise OVH Singapore datacenters with redundant power, NVMe enterprise storage, hardware RAID, and sub-15ms regional latency.

⚡ DDoS & Edge Protection

Cloudflare Enterprise Edge CDN integration, automated Web Application Firewall (WAF), and Fail2Ban automated IP rate-limiting.

2. Data Isolation & Zero Public Model Training

We treat your proprietary corporate knowledge with the highest standard of confidentiality:

No Public Foundation Model Training: Your business documents, customer chats, and knowledge vectors are used solely to generate answers for your organization. They are never ingested into third-party public AI training sets.
Ephemeral Processing: In-flight prompt evaluations and RAG vector searches occur in isolated memory partitions with strict session timeouts.
Role-Based Access Control (RBAC): Granular permissions separate administrative console functions, billing controls, support ticketing, and knowledge ingestion.

3. Authentication & Credential Protection

Customer accounts and API access points are protected by robust authentication controls:

Cryptographic Password Hashing: Passwords are protected using salt-hashed scrypt algorithms with high computational complexity.
Secure Session Management: HttpOnly, Secure, SameSite session cookies with automatic CSRF token verification on all state-mutating requests.
Two-Factor Authentication (2FA): Time-based One-Time Password (TOTP) 2FA support for administrative accounts.

4. Backup, Disaster Recovery & 99.9% Uptime

Automated Daily Backups: Database tables, configuration states, and knowledge embeddings undergo automated encrypted backups daily.
Disaster Recovery: Rapid containerized orchestration via Docker Compose enables rapid node failover in under 5 minutes.
Live Health Monitoring: Real-time automated probes continuously monitor API latency, PostgreSQL connectivity, Redis cache health, and LLM inference uptime via System Status.

5. Vulnerability Disclosure & Responsible Reporting

We welcome responsible vulnerability reports from security researchers and customers:

Please submit suspected security vulnerabilities privately to security@kkcsi.com or via the Client Portal.
Include detailed reproduction steps and refrain from accessing or modifying other tenants' data.
We commit to acknowledging valid security reports within 24 hours and deploying mitigations promptly.
