SYBA Guardian · macOS

Watches your screen. Stops the scam. Lowers your premium.

Guardian sits quietly on your Mac and reads what you read. The instant a phishing page, a fake invoice, or a tech-support scam appears, it steps in before you click. No noise the rest of the time.

It watches quietly

Guardian runs in the background and stays silent. It only speaks up, with a clear, plain-language warning, for a real threat in front of you.

Built private

What stays on your Mac, stays on your Mac.

Guardian is local-first. Every frame is screened on your device before anything is ever sent anywhere. The everyday work on your screen never leaves it.

Local-first screening

Each frame is checked on-device first. If nothing looks wrong, that is the end of it, no network, no cost, no record.

PII redacted before it leaves

Only a frame that already looks suspicious is escalated, and personal information is stripped before it does.

Only suspicious frames are sent

The second-opinion vision model sees the rare risky moment, never your inbox, your banking, or your day.

The insurance angle

Protection you run is protection underwriters reward.

Running Guardian feeds your Cyber Hygiene score. Active, continuous protection is the strongest signal an underwriter can see, and it moves your premium down over time. The coverage behind it is endorsed by Chubb, with capacity up to $5M.

Cyber Hygiene score
A+

Guardian running on your device is one of the score's strongest inputs. Higher score, lower premium, backed by Chubb.

Questions

Is SYBA Guardian on the Mac App Store?

No. Guardian is a direct, Apple-signed download from sybainsurance.com so it can watch your screen and step in instantly, capabilities the App Store sandbox does not allow. You install the signed .dmg yourself.

Does SYBA Guardian send my screen to the cloud?

Almost never. Guardian screens every frame on your device first. Only a frame that already looks suspicious is sent, with personal information redacted, to a vision model for a second opinion. Safe frames never leave your Mac.

How does running Guardian lower my premium?

Guardian feeds your Cyber Hygiene score. Continuous, active protection is the strongest signal an underwriter can see, and it gives Syba a cleaner picture of your risk over time.
