It is primarily developed and maintained by Simon Tatham. PuTTY is available for Windows and Unix platforms and includes an `xterm` terminal emulator. The latest version, 0.83, was released on February 8, 2025. Key Features and Functionality: - Protocol Support: PuTTY supports multiple network protocols, including SSH, Telnet, Rlogin, and SUPDUP, allowing secure and flexible remote connections. - Cross-Platform Availability: Compatible with both Windows and Unix systems, PuTTY provides a consistent user experience across different operating environments. - Terminal Emulation: It includes an `xterm` terminal emulator, facilitating the execution of terminal-based applications on remote systems. - Security Enhancements: The latest release, version 0.83, introduces support for ML-KEM, a NIST-standardized post-quantum key exchange mechanism, enhancing security against potential future quantum computing threats. - Unicode Support: Improved Unicode support allows for the use of characters outside the Windows system code page, accommodating a broader range of languages and symbols. Primary Value and User Solutions: PuTTY addresses the need for secure, reliable, and versatile remote access to computers over a network. By supporting multiple protocols and platforms, it enables users to manage and interact with remote systems efficiently. The inclusion of advanced security features, such as post-quantum key exchange mechanisms, ensures that users' connections remain protected against evolving cybersecurity threats. Additionally, its improved Unicode support enhances usability for a global user base, accommodating diverse linguistic requirements. - **4** discussions - · **100%** answered - · **9** participants ![PuTTY](https://images.g2crowd.com/uploads/product/image/large_detail/large_detail_91ba385b963fa00bce23b532cca3ebba/putty.png "PuTTY") PuTTY Discussions Most CommentedMost HelpfulCommon QuestionsNewest Showing **4** discussions ![Pinned by G2 as a common question](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Pinned by G2 as a common question") G2 Pinned by G2 as a common question • about 3 years ago More Options - Share [![linkedin](/assets/social-logos/linkedin-afe65e46604a5bd5105ab9c856116204040b6b3f2b2d42562fc8071ca0c48ca0.svg "linkedin")](https://www.linkedin.com/shareArticle?mini=true&summary=What+is+PuTTY+used+for%3F&title=What+is+PuTTY+used+for%3F&url=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-putty-used-for) [![twitter](/assets/social-logos/twitter-61aaec80434c71387b8f7326e480592eae71c0a65afd051d66fce9b75a9bf417.svg "twitter")](https://twitter.com/intent/tweet?text=What+is+PuTTY+used+for%3F&url=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-putty-used-for&via=G2dotcom) [![facebook](/assets/social-logos/facebook-350d0b410d6b10debcf893050e803a8633d53561aa42807b087b8daf9be3668f.svg "facebook")](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-putty-used-for) [![gmail](/assets/social-logos/gmail-6db42f21e7c254fae201b112bef0dd15d25223a5cbb32691ce80eab43761eadf.svg "gmail")](https://mail.google.com/mail/?view=cm&fs=1&tf=1&to=&su=What+is+PuTTY+used+for%3F&body=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-putty-used-for%0aWhat+is+PuTTY+used+for%3F) [![mail](/assets/social-logos/mail-d55c53b04bf49872e40cd2443b85a99caa23394e6cf154ae32a9d08377c15d86.svg "mail")](mailto:?subject=What+is+PuTTY+used+for%3F&body=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-putty-used-for%0aWhat+is+PuTTY+used+for%3F) - Copy link - [ ## What is PuTTY used for? ](/discussions/what-is-putty-used-for) What is PuTTY used for?
