sine cura (Latin), without worry
Your PCs already have protection. Sine Cura tells you, in plain English, whether it's working.
How it works
Install the free Windows helper
A small helper app on each PC reads the status of the built-in Windows Security (Microsoft Defender).
Pair with the code from your phone
The iPhone app shows a short pairing code. Type it into the helper and that PC is linked to your account.
Get plain-English alerts
If protection is turned off, falls out of date, or finds a threat, your phone tells you what happened and what to do next.
Features
Every PC at a glance
See whether real-time protection is on and security updates are current on each paired PC, with an overall security score.
Alerts that make sense
Push notifications when Windows Security reports a threat or protection is turned off, written in plain English, not error codes.
Security activity
A history of what Windows Security reported on each PC: threats found, actions taken, and when protection came back on.
Risks to review
Missing updates and known weaknesses on your PCs, such as a version of Windows that no longer gets security updates.
Uses what you already have
No extra antivirus to buy or install. Sine Cura reads the protection that comes with Windows.
You stay in control
Remove a PC or delete your whole account from Settings in the app at any time.

An honest note
Sine Cura Cyber monitors and reports. It does not block, quarantine or remove threats. That job stays with Windows Security (Microsoft Defender) on your PC. Sine Cura tells you whether that protection is on and working, and what to do when it isn't.
