ModernGuard: LLM guardrail API

Intro

GuardionAI provides runtime guardrails for AI agents and multi-channel platforms (MCPs). It is positioned as a unified security gateway for agentic workflows and MCP tools, aiming to secure those workflows with real-time protection and compliance guardrails. The product emphasizes runtime protection rather than development-time controls and offers features intended to reduce prompt-injection and similar runtime threats.

Key Features

• Real-time prompt attack detection to identify and block prompt-injection and related runtime threats.
• PII redaction to remove personally identifiable information from data processed at runtime.
• Compliance guardrails geared toward enterprise GenAI workflows to help enforce policy checks during operation.
• Platform capabilities to protect, monitor, and control AI applications in real time.
• Integration options that include an API for quick integration and a Guardion AI Gateway component to sit between agents/MCPs and downstream services.

Who this is for

GuardionAI is aimed at organizations operating AI agents and MCP tools, and at developers or integrators who use APIs to protect AI applications. The vendor offers enterprise-focused options and contracts, and the commercial model supports pay-as-you-go usage as well as enterprise agreements. Organizations that need runtime monitoring and operational guardrails for agentic workflows are the primary audience.
