CycloneSSL is a lightweight TLS / DTLS implementation targeted for use by embedded application developers. It provides the ability to secure communications over the Internet (e.g. IoT protocols, electronic mail, web server, file transfer, VoIP).
CycloneSSL is available either as open source (GPLv2 license) or under a royalty-free commercial license (non-GPL license). We also propose an evaluation license (90-day license in source form) with technical support for an easier onboarding and effective evaluation of our software.
