The Crisis

A grandmother opens an email and loses her retirement savings. A student watches their crypto wallet drain in real time. A small business owner gets a ransom note on Monday and closes their doors by Friday. This isn't hypothetical — the FBI received 859,000 cybercrime complaints last year, with losses exceeding $16.6 billion (FBI IC3, 2024). Cybercrime is now a $10.5 trillion industry (Cybersecurity Ventures) — bigger than the GDP of every country except the US and China. And 68% of breaches start with a single human mistake (Verizon, 2024) — clicking one wrong link, opening one bad attachment. The protection that actually stops this? Enterprises pay $10-20 per device per month for it. Everyone else gets Norton from 2005.

What We Built Instead

We took the same protection that enterprises pay thousands for and made it run entirely on your machine. Nothing leaves your machine. No cloud. No telemetry. No one watching you. 588 security modules that guard against ransomware, detect if someone's accessing your webcam, alert you when an AirTag is following you, check if your passwords were leaked in a breach, and scan your home network for devices that shouldn't be there. That includes 90 AI agent security modules. Every AI assistant, every chatbot, every agent you let touch your files can be hijacked — prompt injection, tool manipulation, silent data exfil. No one else protects against this. We ship 90 modules for it, and they're all free. The core — 227 modules across 11 domains — is free. Not freemium-free where they harvest your data. Actually free. The full suite is $99 once, forever. No subscription. No renewal. Because when protection costs us nothing to deliver, charging you monthly is just greed.
