ntpd-rs is a security-focused implementation of the NTP protocol, founded by the [[Internet Security Research Group]] as part of their Prossimo initiative for the creation of memory safe Internet infrastructure. ntpd-rs is implemented in [[Rust (programming language)|Rust programming language]] which offers [[memory safety]] guarantees in addition to the [[Real-time computing]] capabilities which are required for an NTP implementation. ntpd-rs is used in security-sensitive environments such as the [[Let's Encrypt]] non-profit Certificate Authority.<ref>{{cite web |last1=Aas |first1=Josh |title=More Memory Safety for Let’s Encrypt: Deploying ntpd-rs |url=https://letsencrypt.org/2024/06/24/ntpd-rs-deployment/ |website=Let's Encrypt |publisher=Let's Encrypt |access-date=18 December 2024 |ref=LEntpd}}</ref> Support for NTS is available.<ref>{{Cite web |title=Network Time Security - ntpd-rs documentation |url=https://docs.ntpd-rs.pendulum-project.org/guide/nts/ |access-date=2025-01-13 |website=docs.ntpd-rs.pendulum-project.org}}</ref> ntpd-rs is part of the "Pendulum" project which also includes a [[Precision Time Protocol]] implementation "statime".
