Protection
A fresh threat feed, every day.
Rempart relies on a signature package updated daily, signed and verified, then scans your Mac without sending anything.
The journey of an update
Collection
Every day, our server fetches the ClamAV signature database and compiles our own list of Mac-specific threats from recognized public sources: Objective-See, Malwarebytes Labs, Apple's XProtect rules and recent macOS vulnerabilities published by the NVD.
Assembly
Signatures are deduplicated, versioned and bundled into a package. A per-version diff avoids re-downloading what your Mac already has.
Signing
The package is signed with an Ed25519 key that never leaves our server. The app verifies this signature before any use: a modified or corrupted package is rejected.
Local scan
Rempart compares your files with the signatures directly on your Mac. No file and no file name is sent to our servers.
In practice
Daily update
Automatic, in the background, a few seconds a day.
Two complementary sources
ClamAV for breadth, our own list for Mac-specific threats.
Ed25519-signed
The same chain of trust as app updates.
Nothing leaves your Mac
The scan and its results stay on your machine.
What protection does not do
MacNeat complements the protections built into macOS (Gatekeeper, XProtect, System Integrity Protection) without replacing or disabling them. Signature-based detection catches known threats: keep macOS up to date and install your apps from trusted sources.
