One layer, used deliberately.
Syspeace detects repeated failed sign-in attempts on Windows Server and blocks the offending addresses. This page explains where that fits, and how to verify what you download.
A complement to your existing controls, not a replacement.
Syspeace does not provide multi-factor authentication, patch management, network segmentation, account lockout policy, endpoint protection, or firewall policy — those remain necessary regardless of whether Syspeace is installed. Syspeace adds a response to a specific pattern: repeated failed sign-in attempts against a server's own authentication surface. See the product page for the full picture.
Confirm what you install matches what Syspeace published.
Every installer on the downloads page is published with a SHA-256 checksum. Compare it against the file you downloaded before installing it on a production server — see Verifying a downloaded installer checksum for the exact steps.
