NTPsec
A secure, hardened, and improved implementation of Network Time Protocol

NTPsec is an open-source, security-hardened implementation of the Network Time Protocol (NTP), derived from NTP Classic originally created by Dave Mills. The project focuses on delivering a codebase suitable for deployments with stringent security, availability, and assurance requirements. It applies best practices in code auditing, verification, and testing, with full public source code access.
NTPsec provides a rigorously audited, open-source NTP implementation available via a public git repository, enabling community review and secure time synchronization deployments.
