What is Shared SSL? Technologies for sharing SSL certificates

Introduction

SSL (Secure Sockets Layer) certificates play a critical role in securing websites and ensuring that sensitive information is transmitted securely over the internet. Traditionally, each website required its own SSL certificate, which can be costly and time-consuming to manage. However, with the advancement in technology, a solution called Shared SSL has emerged, allowing multiple websites to share a single SSL certificate. In this blog post, we will explore what Shared SSL is and how it works.

Understanding Shared SSL

Shared SSL, also known as a shared certificate or a wildcard certificate, enables multiple websites hosted on the same server to share a single SSL certificate. Instead of each website having its own unique certificate, all websites are assigned a common certificate. This not only saves costs but also simplifies certificate management for website owners.

How Shared SSL Works

When a visitor accesses a website protected by shared SSL, their browser establishes a secure connection with the server using the shared SSL certificate. The certificate verifies the identity of the server, ensuring the authenticity of the website. However, with shared SSL, the individual domain names of the websites are not present in the certificate. Instead, a wildcard or a common name is used in the certificate, allowing it to be shared across multiple websites.

Benefits and Limitations of Shared SSL

Benefits:
1. Cost savings: Shared SSL eliminates the need for each website to have its own certificate, reducing costs for website owners.
2. Simplified management: With shared SSL, website owners only need to manage a single certificate, making the management process more efficient.
3. Seamless scalability: Shared SSL makes it easier to add or remove websites on the same server without the need for additional certificates.

Limitations:
1. Limited control: Shared SSL provides less control compared to dedicated SSL certificates, as the configuration and settings are shared among multiple websites.
2. Branding limitations: Shared SSL certificates do not display the individual website’s domain name, which may impact brand recognition and trust.
3. Security risks: If one website sharing the SSL certificate is compromised, it could potentially affect the security and trustworthiness of other websites using the same certificate.

Conclusion

Shared SSL certificates offer a cost-effective and convenient solution for website owners to secure multiple websites without the need for individual certificates. However, it is essential to consider the limitations and potential security risks associated with shared SSL. Depending on the specific requirements of your website, shared SSL might be a suitable option or you may opt for dedicated SSL certificates for greater control and branding advantages.
