Lavabit
Lavabit is a secure email service that emphasizes privacy and security. It provides end-to-end encryption for users' email messages, making it difficult for anyone else to intercept or read the messages. The company was founded in 2004 and is based in the United States. Lavabit also offers a range of additional security features, such as two-factor authentication and the option to encrypt email attachments. The service is popular among journalists, activists, and others who need to protect sensitive information from prying eyes. Lavabit gained widespread attention in 2013, when it shut down its service in order to avoid complying with government demands for user data. The company has since returned with a renewed focus on privacy and security.
