AI Security Gateway acts as a specialized firewall and LLM proxy designed for developers integrating large language models into sensitive environments. It functions as a stateless governance layer that sits between your application and over 300 supported AI models.
The platform prioritizes data sovereignty by enforcing real-time redaction of more than 28 PII entities, including image-based data via OCR. Beyond security, it addresses operational overhead through autonomous cost-optimized routing and per-project budget enforcement, which can significantly reduce expenses compared to standard GPT-4o usage.
Users can implement the gateway with minimal code changes, gaining access to audit-ready security logs and token quota management. It is designed for organizations needing to meet compliance standards like GDPR, HIPAA, or PCI-DSS while maintaining model versatility.
By preventing vendor lock-in and ensuring no prompt content is persisted, the tool provides a neutral infrastructure for scaling AI deployments safely. Buyers should evaluate the specific PII detection limits and the "Wallet mode" requirements for their specific organizational workflows.

The gateway uses a built-in DLP policy engine to scan incoming and outgoing requests. It identifies over 28 types of PII entities, including text and images via OCR. Once detected, sensitive data is automatically redacted or cleaned before the prompt reaches the model provider, ensuring that PII never leaves your controlled environment or persists in third-party logs.
Yes, but this capability depends on your subscription level. While the gateway supports over 300 models, the Bring Your Own Key (BYOK) feature is specifically reserved for users on the Pro plan. This allows for zero-percent markup on provider costs while still benefiting from the gateway's security, routing, and budget enforcement features.
