What are Free SSL & TLS Certificate Providers?
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. Compare and read user reviews of the best Free SSL & TLS Certificate providers currently available using the table below. This list is updated regularly.

ManageEngine Key Manager Plus is a web-based key management solution that helps you consolidate, control, manage, monitor, and audit the entire life cycle of SSH (Secure Shell) keys and SSL (Secure Sockets Layer) certificates. It provides visibility into the SSH and SSL environments and helps administrators take total control of the keys to preempt breaches and compliance issues. Similarly, managing a Secure Socket Layer (SSL) environment can be daunting when organizations use a large number of SSL certificates issued by different vendors with varying validity periods. On the other hand, SSL certificates left unmonitored and unmanaged could expire, or rogue/invalid certificates could be used. Both scenarios could lead to service downtime or display of error messages that would destroy customer trust in data security and, in extreme cases, even result in security breaches.Starting Price: $595 per year

SSL For Free
SSL For Free
Never pay for SSL again. Powered by ZeroSSL with free 90-day certificates. Our free SSL certificates are trusted in 99.9% of all major browsers worldwide. Protect user information, generate trust and improve search engine ranking. Wildcard certificates allow you to secure any sub-domains under a domain. If you want to secure any sub-domains of example.org that you have now or in the future you can make a wildcard certificate. To generate wildcard certificates, add an asterisk to the beginning of the domain(s) followed by a period. Wildcard certificates will also secure the root domain, so there is no need to re-enter the root domain in the process. For example, to create a wildcard domain for example.org, enter *.example.org. If you need certificates for multiple domains, such as example.org and example.com, you will need to create a separate wildcard certificate for each domain. Domain verification will be required for each domain. -
