Plug in
It shows up as a network device.
The AI Firewall
A machine-wide firewall for AI tools
Guardrails on every request and response. No harness setup.
Prelaunch is live. $500 goal. 30-day campaign when funding opens.
The problem
Your AI software talks to the internet all day. Almost nobody is watching what it sends or receives.
ChatGPT, Claude, Copilot, Cursor, and coding agents pull untrusted pages in and send data out to servers you do not control.
Antivirus and browser protection usually miss that path. The traffic is encrypted. A bad command, a poisoned instruction on a webpage, or a private leak can happen before you notice.
What Aegis does
A firewall for that traffic
ScopeAnthropic, OpenAI, Gemini, and local models you run yourself.
InspectRequests and responses both ways, including live streams.
DecideAllow, block, modify, or ask. If something fails, Aegis blocks. No special plugin in the AI tool.
| Decision | Target | What was gated | Direction |
|---|---|---|---|
| Allow | Anthropic /v1/messages | Request body matched allow rules | Out |
| Block | Fetched webpage → prompt | Prompt injection classifier | In |
| Ask | Cursor tool: Read | Waiting for your OK before the file goes out | Out |
| Modify | Gemini stream | NSFW filter on a response frame | In |
| Allow | Local model on your network | Hosted and local models both count | Out |
No rows match this filter.
Example rows, not live traffic.
Cloud, Dongle, and Edge
One filter stack. Cloud, USB, or local.
Aegis cloud filtering service
SaaS · standalone installer · or through the USB products
- The filter stack as SaaS: prompt injection classification and NSFW filtering.
- Zero data retention from day one. No telemetry.
- The filter backend never sees API keys. Keys stay yours. It only sees payloads.
USB Plug and Play AI Security Dongle
$50 · Raspberry Pi Zero 2 W · Wi‑Fi · custom 3D printed case
- Runs Aegis on the device. A regular USB network device.
- Classification uses the cloud filter stack, so prompts go to us. Zero data retention applies.
- AI agents cannot tamper with it.
- Micro-USB to USB-C cable included. Host still needs certificates and network settings.
USB Plug and Play Edge Filtering Device
$500 · Raspberry Pi 5 + AI HAT+ 2 · Ethernet and Wi‑Fi
- Same network software as the Dongle, plus Ethernet.
- Runs the same filter backend as cloud, locally, for one deployment. Prompts stay on the device.
- Needs its own power adapter. Ships with adapter and USB-C cable.
- AI agents cannot tamper with it. A regular USB network device.
Setup
Plug in the USB device. Finish certificates on a setup page.
02
Setup page opens
Like airport or university Wi‑Fi: a page walks you through certificates and network settings.
03
Keep your tools
Aegis is on the network path. No special plugin in the AI tool.
Who it is for

You use AI coding tools and want control over what they send, receive, and execute.
Teams
You need to manage AI traffic across machines.
Everyday use
You want a gate on what reaches your AI.
Parents
You want oversight of how your kids use AI.

FAQ
Prompts, keys, platforms, and speed.
The cloud service runs the filter stack as SaaS. The Dongle uses that cloud stack, so prompts go to us. We offer a zero data retention policy, like popular VPN services. The Edge Filtering Device runs the same filter backend locally, so those prompts stay on the device.
No. Keys stay yours. The filter backend never sees API keys, it only sees payloads.
No. “Virus” in computer terms means code that does what you did not intend. We are not promising to stop every jailbreak forever. We ship inspect / allow / block / log / modify at the AI chokepoint, with fail-closed defaults.
The USB products are regular USB network devices. Cloud filtering is also a standalone installer. Mobile is a stretch goal, but we are designing for phone support.
The project will be open source with a non-permissive license for commercial use. If the company folds, early backers get a perpetual license to all source code. We have a working proof of concept on GitHub under GPLv3.
Yes, a bit, especially when gating streams. Correctness first. Expect filter latency on gated events, not random freezes.
