SYBA Cybersecurity Agent for Mac

The AI agent that guards your whole computer. And shows you how.

A cybersecurity agent that lives on your Mac. It watches your screen for scams, guards your network, scans for compromised software, and answers “am I safe?” by actually checking. You watch it think the whole way. Free, private, on-device-first, backed by the people who pay the claim.

What it does

Nine ways it has your back, all day.

Watches your screen, not just your browser

The agent reads what is actually on your screen the way a fraud analyst would — across every app, not just the web. It catches the fake invoice, the bogus support pop-up, the scam your browser never sees.

Stops the scam mid-call

When a remote-access tool is running and a banking or crypto page is open, the agent steps in with a full-screen stop and a spoken warning. The single moment that saves you — or a parent — from a live social-engineering scam.

Guards your network

See every device on your Wi-Fi, get told the moment a new one joins, and know if your DNS, Wi-Fi security, or open ports leave you exposed. All on-device, no packet snooping.

Scans for compromised software

A read-only inventory of your installed packages, editor and browser extensions, and developer tools — checked against the latest known-bad list. Catches the supply-chain compromise before it catches you.

A chat agent that does, not just talks

Ask "am I exposed?" or "is this safe?" and it actually runs the scan — your machine, your network, your software — then answers in plain English. Attach your screen to any question.

Quick-ask from anywhere

Press ⌘⇧Space and a calm spotlight appears over whatever you are doing. Ask a question, get a security-grounded answer with sources, close it. No app-switching.

Watch it think

A live trail of thought shows you exactly what the agent is checking, in real time. Protection you can see is protection you can trust.

A tamper-evident record

Every verdict is written to a cryptographically chained log. If the worst happens, you have a verifiable record of what was flagged and when.

Privacy you can audit

Everything is screened on your Mac first. A privacy receipt shows you exactly what left the device and what was held back — down to the byte. Nothing else leaves.

How it works

Up and running in two minutes.

Download and grant

Install the app, grant Screen Recording and Notifications, and the on-device protection turns on. The local checks — screen heuristics, network sentry, machine hygiene — run with no account and no data leaving your Mac.

Let it guard you

Turn it on and forget it. The agent watches quietly, narrates what it sees, and only speaks up when something actually matters — a scam, a new device, a compromised package.

Always on
