planck

planck Secure Email is the end-to-end encryption and decentralized identity management plugin for your own email client. It does not require migration or installation of any new infrastructure. You keep using your current e-mail client by installing a simple plug-in. Unlike centralized server-based security, planck Secure Email works directly on your devices, based on Zero Trust principles. As you keep communicating with your internal and external contacts, encryption keys are automatically exchanged, and your devices are always in sync. By working client side, it provides superior security, giving you full control of senders' identity trust. It adds unique functionality, such as anti-malware detection on end-to-end encrypted content.
