LLM Security Gateway - Guardian Layer

Guardian Layer is a sovereign enterprise AI gateway and LLM proxy that secures AI usage by masking PII, enforcing policies, managing LLM access, tracking costs, and generating compliance evidence. It sits inline between enterprise applications and Large Language Models to deliver centralized governance and observability across 100+ AI models. The system is built by Hidden Brains, a 23-year-old AI-powered advanced software development company.

The platform provides real-time redaction that strips PII, PHI, secrets, and proprietary code from traffic in under 30 milliseconds using a hybrid engine combining pattern matching with transformer-based semantics. It also blocks prompt injection, jailbreak attempts, and denial-of-wallet abuse at the boundary before the model sees them. Every response is checked for hallucination risk, toxicity, and brand-voice drift before delivery.

Guardian Layer operates as a single endpoint that allows secure access, routing, and cost management across 100+ LLMs by connecting existing OpenAI-compatible SDKs. It is LLM-agnostic and can be hosted in your cloud, VPC, or on-premises infrastructure. Users can deploy it in minutes by simply swapping one line of code in their base_url configuration.

The system offers immutable audit trails and visibility tools that help organizations demonstrate compliance across every AI application. It supports policy-as-code governance to ensure consistent enforcement of rules. These features are designed to protect sensitive data and enforce AI policies in real time.

The solution is designed for enterprises that need to secure interactions with 100+ AI models while maintaining centralized control. It suits organizations deploying custom AI apps, AI code assistants, MCP integrations, or homegrown GenAI pipelines. It is particularly useful for those concerned about data leaks to third-party LLMs or vector databases.

To get started, visitors can book a live demo or request a call by providing their name, email, phone, organization, and requirements through the contact form. The platform also offers a REST API for direct integration. Users can explore real-world use cases to see how it protects every AI interaction before it reaches the model.

The platform is developed by Hidden Brains, which describes itself as a 23-year-old AI-powered advanced software development company. It is headquartered in the UAE with an office at Metropolis Tower, Al Abraj Street. The company focuses on building secure, scalable, and intelligent enterprise solutions.

The system integrates with major providers including OpenAI, Anthropic, and self-hosted LLMs. It also connects with vector databases to prevent data leaks. The architecture allows for seamless swapping of one line of code to route traffic through the gateway.

Some reviewers on Reddit have expressed concerns about prompt injection, agent tool-abuse, and unintended tool calls in production environments. They are looking for ways to handle bypassing guardrails and data exfiltration through RAG context. Guardian Layer aims to address these specific production challenges.

The platform supports continuous monitoring and 24/7 alerting to detect and respond to threats in real time. It provides visibility and enforcement tools within a dedicated guardian portal. This allows security teams to manage risks proactively rather than reactively.

The system maps its controls directly to the OWASP LLM Top 10 and NIST AI RMF standards. It covers 0 OWASP LLM risks according to the company's claims. This alignment ensures that security teams receive runtime enforcement rather than just a static checklist.

The service includes content moderation to stop harmful, inappropriate, or off-brand output from reaching users. It also filters and obfuscates PII and secrets on the fly to prevent data leakage. These capabilities help maintain brand consistency and data integrity.

The contact information provided includes a business phone number at +971505417174. Users can also reach out via the website's contact form which requires name, email, and phone details. No personal or employee email addresses are listed in the public profile.

The platform claims to be deployed in minutes with a simple configuration change. It is designed to be LLM-agnostic and works across various environments including on-premises and cloud setups. The goal is to deliver enterprise-grade AI guardrails through real-time data redaction and policy enforcement.
