Data security, encryption, and UK data residency

Security Philosophy

Bidding and procurement involve commercially sensitive information, pricing models, and private evidence. Velstrian Tenderworks implements enterprise-grade zero-trust principles across all customer data.

UK Data Residency

All Velstrian infrastructure, databases, and document vaults reside in sovereign UK data centres (London region). Your data never leaves UK jurisdiction, satisfying crown procurement standards and NHS Digital guidelines.

Data Encryption & AI Privacy

• At rest: AES-256 encryption across all storage volumes, database entries, and backups.
• In transit: TLS 1.3 enforced across all API endpoints and web connections.
• No AI Model Training: Your uploaded documents, bids, and prompt responses are strictly private. We never use your proprietary data to train public or shared artificial intelligence models.
