GPTStone by Trust Fabric
GPTStone, by Trust Fabric, is a zero-trust AI security platform that sits between you and any LLM, checking messages both ways in real time (a "dual-layer AI firewall"). It strips sensitive data from prompts before the AI sees them, then scans replies for data leaks, prompt injection, and policy violations, using a purpose-built security model. Data in transit is encrypted with TLS 1.3, stored data with AES-256 (ISO/IEC 18033), and logins/API keys with FrodoKEM, a post-quantum method built to resist future quantum attacks. It also aligns with major privacy laws, GDPR (EU), FADP (Switzerland), CPRA (California), and KVKK (Turkey), and is available individually via the website or for enterprises via API.
