THE PROBLEM WITH CLOUD AI SECURITY
Most AI security platforms route your prompts through their own cloud to analyze them. That means your sensitive data is sent to yet another external server — before any protection even kicks in.
01
Cloud-routed analysis
Your prompts travel through a vendor's servers for scanning. Who's securing the security tool itself?
02
Single-tool coverage
Most solutions protect only one application. Employees using other AI tools remain completely unmonitored.
03
Requires connectivity
Cloud-dependent security fails offline, in air-gapped environments, or during vendor downtime.
Patronus never sends your data anywhere. Everything happens on your device — in real time, under your control.
HOW PATRONUS WORKS
Local-first security in three steps.
1
Intercept
A lightweight network-layer agent installed on the endpoint captures every AI request made by the device — regardless of app, browser, or provider. Nothing bypasses it.
2
Analyze Locally
The on-device inspection engine checks every prompt and response against your configured policies. No data leaves the machine during this process.
3
Enforce Policy
Threats are blocked, PII is automatically redacted, suspicious activity is flagged. Every event is logged locally, providing a forensic audit trail for compliance.
SYSTEMWIDE COVERAGE
Patronus operates at the network layer — not inside a browser extension or a single app. It intercepts every AI request the device makes, regardless of tool, provider, or application. Shadow AI has nowhere to hide.

LOCAL-FIRST ARCHITECTURE
Unlike cloud-based security vendors who analyze your AI traffic on their own servers, Patronus runs the entire inspection pipeline locally. Full GDPR compliance by design, zero additional data exposure, and complete protection in air-gapped environments.
REAL-TIME PROTECTION
Patronus inspects every prompt and response in milliseconds on the device itself. Prompt injections, jailbreak attempts, PII leaks, and policy violations are caught and stopped before they reach the model — with zero impact on workflow speed.

WHO PATRONUS PROTECTS
1
Enterprise AI Rollouts
Monitor and control Copilot, ChatGPT Enterprise, and custom LLMs company-wide without per-tool configuration.
2
High-Compliance Industries
Finance, legal, and healthcare teams proving GDPR & CCPA compliance for every single AI interaction.
3
AI Agent Environments
Autonomous agents accessing files and APIs — Patronus defines exactly what actions they are permitted to take.
4
Air-Gapped Deployments
Defence, critical infrastructure, and secure facilities where cloud connectivity is simply not an option.
DATA SOVEREIGNTY
Your infrastructure.
Your rules. Your data.
Patronus runs entirely on the endpoint. No prompts, no documents, no metadata ever leave your perimeter. GDPR and CCPA compliance is a consequence of how we're built, not a setting.
Audit-Ready by Default
Every AI interaction logged with forensic-grade detail. Generate GDPR, CCPA, and SOC 2 compliance reports on demand.
SIEM Integration
Stream AI security events to Splunk, Elastic, or Datadog. Native connectors embed Patronus in your existing SOC.
SECURITY & COMPLIANCE
Enterprise-grade security, built for every industry.
