StratoKey Unveils API Gateway for SaaS, Cloud and AI Security

APIs are now the connective fabric of modern enterprise systems, and securing them has become critical. StratoKey’s new API Gateway applies field-level encryption, tokenization, and policy enforcement to data in motion, closing exposure gaps that traditional gateways do not address. The release marks a significant evolution of the StratoKey Cloud Data Protection Platform, already trusted for data and identity protection in regulated industries including defense, manufacturing, healthcare, financial services, and infrastructure.

What is an API Gateway?

An API Gateway is a control point that manages and secures traffic between applications, services and external systems. It routes requests, enforces authentication, rate limits and other request-level policies, serving as the control plane for APIs.

Payload-Level Security, Not Just Traffic Management

Most gateways secure the connection. StratoKey secures the payload. Sensitive fields are encrypted or tokenized before leaving the environment, ensuring that regulated data remains controlled even when sent to cloud, SaaS, or AI services. This makes the gateway ideally suited to assist organizations meet compliance requirements whilst operating with connected systems where data moves rapidly between distinct systems.

A Response to AI Growth and Increasing Compliance Pressure

Analysts warn that surging adoption of SaaS, automation, and generative AI is increasing exposure risk for sensitive and regulated data. Gartner projects that by 2028, one in three enterprise applications will include agentic AI, up from less than one percent in 2024. These systems are already triggering workflows, transferring data, and creating new integrations at speed.

Regulated sectors, including defence, aerospace, healthcare, and finance, now face the dual challenge of modernizing infrastructure while maintaining compliance with frameworks such as CMMC, ITAR, and HIPAA. The StratoKey API Gateway addresses this without re-architecting existing systems, acting as a policy and protection layer that secures data flows across cloud, legacy, and AI-driven environments.

Designed for Compliance, Modernization and High Assurance Use Cases

The API Gateway introduces field-level encryption, tokenization, data sovereignty enforcement, and real-time policy control. It generates structured audit logs and streams telemetry across integrated systems. Because no code changes are required, legacy systems can be modernized progressively and without operational disruption.

AI, SaaS, and Third-Party Access Controls Built Into the Pipeline

The API Gateway inspects and governs data sent to AI systems, SaaS platforms, and external integration layers. Sensitive data is can be redacted, tokenized, or blocked before leaving compliant environments. Inputs and outputs are sanitized to reduce prompt-injection risk and limit what external systems can access or infer. This enables controlled adoption of AI and third-party services without uncontrolled data exposure.

Complements Existing StratoKey Products for Full End-To-End Data Protection

The API Gateway can be licensed standalone or as part of the overall StratoKey data protection platform. Many organizations begin by securing SaaS applications with the StratoKey Cloud Data Protection and Identity Gateways, then extend controls to data in motion using the API Gateway. Together, they form a unified architecture for identity, data and API security across the Cloud Data Protection Platform.
