What are SSL & TLS Certificate Providers for Windows?

SSL and TLS certificate providers issue digital certificates that secure online communications by encrypting data between a user’s browser and a website. These certificates authenticate the identity of a website, building trust with visitors and protecting sensitive information like passwords, credit card details, and personal data. SSL/TLS providers offer various types of certificates, such as domain validation (DV), organization validation (OV), and extended validation (EV), each with increasing levels of verification. Many providers also offer tools for managing and renewing certificates, as well as scanning for vulnerabilities to enhance site security. With SSL and TLS certificates, businesses ensure their websites are secure, compliant, and trustworthy for users.
