Solution / Shadow AI
See which AI tools your team uses.
Discover AI activity on company computers, including use outside your approved tool list. Monitor gives you visibility. Protect adds rules to allow or block detected AI connections.

01
Why your current stack can't see it
CASB sees the SaaS, not the prompt
Cloud access brokers know chatgpt.com was visited, not that customer data was pasted into it.
DLP sees encrypted bytes
Classic DLP inspects file transfers. AI prompts travel inside encrypted API calls it can't interpret.
Firewalls see a destination
A domain allow-list can't distinguish harmless AI use from an agent exfiltrating your source code.

How Patronus discovers shadow AI
Network-layer detection
A lightweight endpoint component identifies AI traffic across all apps and browsers, provider-agnostic, before encryption hides the signal.
AI inventory
Every discovered tool, model and provider lands in a live inventory: who uses what, how often, with which risk profile.
From visibility to control
Once usage is visible, define policies: allow, monitor, or block specific AI systems, enforced locally on the device.

Shadow AI, frequently asked questions
What is shadow AI?
Shadow AI is the use of AI tools, models or AI-powered features inside an organization without the knowledge or approval of IT and security teams, from ChatGPT in the browser to AI extensions, local LLMs and embedded AI features in SaaS products.
Why is shadow AI a security risk?
Unmonitored AI usage moves sensitive data outside your control: prompts can contain customer data, credentials or source code, and AI agents can execute actions on internal systems. Without visibility there is no policy, no audit trail and no GDPR/AI Act compliance.
How does Patronus detect shadow AI without seeing my data in the cloud?
Detection runs entirely on the endpoint, in the network path. AI traffic is classified locally using pre-TLS signals and behavioral fingerprints, no prompts or documents ever leave the device.
Does this work for AI tools you don't know yet?
Yes. Detection is provider-agnostic and behavior-based, so unknown or obfuscated AI transports are classified without relying on a list of known API signatures.
Why can't our firewall catch AI tools running locally on laptops?
Because a network firewall only sees traffic that leaves the laptop, and only as an encrypted destination. A local model produces no outbound traffic at all, and a browser AI extension looks like ordinary HTTPS. Detection has to happen on the device, where the process, the payload and the destination are still visible.
Is there a tool that monitors AI usage before it hits our network?
Yes. Patronus runs on the endpoint and classifies AI traffic in the local network path, before encryption and before the request reaches your gateway. It covers browser tools, desktop apps, IDE assistants, local models and agents, without per-tool integrations.
How do I get visibility into what data employees are feeding into local LLM models?
Only an endpoint component can see that, because prompts to a local model never cross the network. Patronus captures the prompt on the device, classifies it for PII, secrets and document type, and records the decision in a local audit log. The content itself does not leave the machine.
Which tools help discover shadow AI in an organization?
Three approaches exist: CASB and proxy logs (they see SaaS domains, not prompts or local models), surveys and licence audits (they see what people admit to), and endpoint-level detection (it sees actual usage, including local models and extensions). Patronus takes the third route and builds the inventory from real traffic on the device.
Does Patronus use an LLM to detect AI?
No. Detection works with signals from network traffic and with small, specialized classification models such as Wolf Defender. No prompt is sent to a language model, and Patronus does not generate text itself.
Does Patronus send my prompts to OpenAI or another provider?
No. The check runs on the device. Only what your rules allow goes to the AI tool you chose yourself. No content goes to Patronus.
Do I have to replace ChatGPT or Copilot with something else?
No. You keep using your tools as before. Patronus sits on the computer in front of them and makes the usage visible, Protect also checks content and actions.
Is Patronus a VPN or a proxy?
No. Patronus runs as software on the device in the network path. Traffic takes no detour through third-party servers, and there is no central point that can fail.
Can my employer see what I write to the AI?
Content stays on the device. Only metadata can reach a central view: which tool, which category, which decision. Whether and how that metadata is evaluated is up to your company.
Does Patronus work with local models such as Ollama?
Yes. Detection works on how a connection behaves, not on the provider's name. Local models, internal services and new tools are covered just like the big providers.
Do I need an internet connection?
No. Detection, inspection and decision run offline on the computer. That includes isolated networks.
Does Patronus slow down my computer?
The models are built for their task: under 10 ms per detection and under 100 MB of memory. There is no noticeable difference in chat.
