WoSign is a certificate authority that offers a range of digital security solutions, including SSL/TLS certificates, designed to secure and authenticate websites and online communications. The company provides various types of certificates to accommodate different security needs, from basic domain validation to more comprehensive organization validation. WoSign is committed to promoting a safer internet by enabling encrypted connections. However, it is important to note that WoSign faced significant scrutiny and loss of trust in 2016 due to incidents involving improper certificate issuance and management, which led to major web browsers and operating systems removing WoSign from their trusted root certificate programs. This has impacted its reputation and acceptance in the digital security landscape.
