Sensitive data stays on the device, not with the provider.

The starting point
AI is already in the building.
Nobody knows where.
Shadow AI
A typical mid-sized company runs more than 20 AI tools. Two of them are approved.
Discover shadow AI →Company secrets in the prompt
Price lists, design data, HR files, source code. Once pasted, they leave the building.
Stop data loss →No evidence
The EU AI Act requires you to know and log your AI usage. An outdated spreadsheet will not do.
See AI Act compliance →What you get
See it. Rule it. Prove it.
A small piece of software on the company machine handles three things, without anyone changing how they work.
01
A complete AI inventory
Visible within minutes: which tool, which department, how often. Including the tools nobody ever approved.
02
Guardrails instead of bans
Define per team what is allowed and what never leaves the building. Enforced in real time, on the device.
03
Evidence as a by-product
Every decision is logged. For an audit, ISO or the AI Act, one click is enough.

In the live demo you pick a case, set a rule and watch what reaches the provider and what lands in the audit log. Runs in your browser, takes a minute.
Cross-Provider Protection
One firewall around every AI provider.
Detection works on traffic behavior, not on names. New tools show up the moment they appear.
AI Security is fragmented across tools
How Patronus works?
Patronus starts with the foundation most teams are missing today: visibility. From there, protection, policy, and governance become much easier to implement with confidence.
On-Device AI Firewall
Instead of relying on multiple tools, integrations, or extensions, Patronus is designed as an AI firewall operating in the network path on the endpoint. Our novel detection mechanism identifies AI traffic in one-digit milliseconds and allows us to detect AI interaction across apps, browsers, and providers.
On-Device Protection
Nobody likes another cloud dependency, especially when dealing with sensitive data, which is common in AI systems. Cloud compute enables fast detection, but comes at the cost of privacy and doesn't always deliver the best performance. At Patronus, we design and build our own AI systems to run directly on-device, in real time. Our methods achieve state-of-the-art performance, competing with LLM-based solutions at a fraction of the cost.
01 / AI Detection
See AI traffic before it looks familiar.
Provider-agnostic network intelligence that detects AI traffic in real time, before encryption hides the signal.

02 / AI Act Readiness
Assess your AI Act readiness.
23 questions derived from the original text of Regulation (EU) 2024/1689, focused on the technical and organizational obligations applicable to deployers. The output is a personalized PDF report with sub-scores per dimension and prioritized findings.

03 / AI Models
Purpose-built models for runtime protection.
Detect prompt injection, data exposure, and agent abuse before threats reach the model, locally and in real time.

04 / Security Library
Keep AI security local, fast, and auditable.
Patronus Ark brings prompt injection, DLP, PII, and agentic tool protection into one open-source local security gateway.

For who is Patronus?
Patronus protects AI interactions at the endpoint. The value looks different depending on whether you own security, build with models every day, roll AI out across a company, or use AI privately.
Make AI usage visible, auditable, and controllable across the company.
Patronus gives security teams company-wide visibility into AI activity on managed devices, with audit-ready logs, runtime control over AI usage, and local protection for sensitive data.
- Generate audit-ready logs for AI usage across tools, providers, and local models.
- Enforce runtime control over which AI systems, prompts, and actions are allowed.
- Strengthen SIEM, compliance, and incident response workflows with endpoint-level AI visibility.
What teams use Patronus for
From shadow AI discovery to EU AI Act compliance, four ways organizations put the on-device AI firewall to work.
A new era of AI Security
As AI systems become more powerful and autonomous, security must move closer to the user. Patronus Protect delivers on-device protection that safeguards privacy and data sovereignty while detecting threats before data leaves the device. We prevent malicious actions and provide real access control for autonomous agents - locally, transparently, and in real time.
