The Agent and MCP Security Gateway
Unified Security forAI Agents and MCPs
AI agents and MCP tools are already operating on your data — SIEM, DLP, and identity layers can't see. GuardionAI sits in the execution path to discover, redact sensitive data, and enforce protection.

Threat Coverage
What We Protect Against
The most critical threats to AI agents — from malicious inputs to autonomous mistakes. Mapped to OWASP LLM Top 10 and Agentic AI threat frameworks.
Prompt Injection
Detect and block attempts to override system instructions or hijack agent behavior through crafted user inputs.
System Override
Prevent attackers from manipulating the agent into ignoring safety boundaries or executing unauthorized actions.
Web Attacks
Guard against XSS, CSRF, and web-based exploits targeting agent-powered interfaces and APIs.
MCP Tool Poisoning
Detect compromised or malicious tool definitions in Model Context Protocol integrations before execution.
Malicious Code Execution
Block attempts to generate, inject, or execute harmful code through agent code interpreters and sandboxes.
NSFW Content
Filter unsafe, explicit, or inappropriate content across 12 risk categories with configurable sensitivity thresholds.
PII & Credential Exposure
Identify and redact PIIs and secrets before it reaches external models or storage.
Confidential Data
Prevent sensitive business data, trade secrets, and proprietary information from leaking through AI interactions.
Off-Topic Drift
Keep agents focused on their intended purpose and prevent misuse for unrelated or unauthorized tasks.
Unauthorized Access
Prevent unauthorized access to sensitive data and resources through agent interactions.

The product
One Gateway. Four layers of protection.
No code changes. No SDKs. A drop-in proxy that sits between your AI tools and your systems — giving you instant observability, enforcement, and compliance coverage.
Agent Action Tracing
Every tool call, data access, and autonomous decision captured and traced in real-time. Eliminate the black box before your auditors do it for you.
Rogue Agent Prevention
Detect prompt injection, unauthorized API calls, shell execution, and capability drift the moment they happen — not after the incident report.
Automatic PII & Secrets Redaction
SSNs, API keys, credentials — stripped from inputs and outputs before they ever leave your perimeter.
Adaptive Guardrails
Prompt/content-based and behavior-based guardrails tuned continuously to your use case, your users, and your risk appetite.

SOC 2 Type II, GDPR, HIPAA, and LGPD-ready. Incident-ready logs exportable to your SIEM. Built for LatAm and global regulatory environments.
Dedicated Onboarding
A GuardionAI engineer joins your team for the first 30 days. Custom guardrail configuration, integration review, and go-live sign-off. Deployment guaranteed in under 20 minutes.
BYOM Guardrails
Bring your own fine-tuned model to power the guardrails layer. Combine with our pre-built policies or replace them entirely. Your risk surface, your rules.
SLA & Uptime
99.99% gateway uptime SLA. Distributed infrastructure with automatic failover. P99 < 20ms overhead on agent workflows.
Trusted by CISO-Grade Teams
Deployed in production at leading LatAm fintechs. Founded by former Apple Siri runtime security engineers. Backed by Google for Startups, NVIDIA Inception, and Entrepreneurs First.
“GuardionAI gave us the visibility we were missing. We deployed agentic workflows across our entire customer operations team — with a kill-switch and a full audit trail for every autonomous action. Our compliance team finally stopped asking us to slow down.”
