Loyd K, a South Korean enterprise AI search and agent platform company led by CEO Kim Dae-hoon, has launched DO-GATE, an AI security gateway that helps companies apply consistent security rules when employees use external commercial large language models such as ChatGPT, Claude and Gemini.

The product targets a growing problem in finance, telecoms, retail and other sectors: "shadow AI", the unauthorised use of AI services, which raises the risk of leaking core corporate assets and personal data. DO-GATE sits between a company's internal systems and external LLM services, controlling access rights and monitoring data traffic in real time. Rather than blocking outside services outright, it creates a policy-based environment in which they can be used safely.

Loyd K has filed a patent application for the core technology, a method and device for filtering, justification-approval vector issuance and anomaly monitoring to control LLM-based AI use.

Demo and talk in Daegu

The company is showing the product at N³etFraST 2026, held from November 11 to 13 at the Interburgo EXCO Hotel in Daegu and organised by the Korea Institute of Science and Technology Information (KISTI). At its booth, Loyd K demonstrates DO-GATE's real-time security filtering and governance controls.

On November 12, security director Oh Se-hyun speaks on security technology and governance in the AI era, covering how generative AI changes the threat landscape and a framework for balancing data control with productivity. "The success of generative AI adoption depends on the control that balances protecting sensitive data with using external services," Oh said, adding that DO-GATE aims to ease concerns about leaks while supporting compliance and productivity.

What comes next

Loyd K plans to combine DO-GATE with its earlier enterprise AI work platform, DO Solution 3.0. The goal is a product family that lets companies deploy AI agents while keeping full control of internal data, and a management system covering generative AI from evaluation and operation to post-incident security audits.
