When it comes to securing data transmitted between a user’s browser and your WordPress site, the choice between TLS (Transport Layer Security) and SSL (Secure Sockets Layer) is crucial. Both protocols encrypt data to prevent unauthorized access, but they have key differences. Here’s a guide to help you decide which protocol is best suited for your WordPress website.
Understanding SSL and TLS
SSL was the original protocol designed to secure communication over the internet. However, due to vulnerabilities, it has largely been deprecated, and its use is discouraged. TLS is the successor to SSL, designed to address the weaknesses of its predecessor. It provides a more secure and robust framework for securing data during transmission.
Security Considerations
SSL has known vulnerabilities, including the infamous POODLE and BEAST attacks. These vulnerabilities pose a significant risk to the security of data transmission. TLS is continuously updated to address security flaws. It is considered more secure than SSL, with the latest versions providing strong encryption algorithms and protocols.
Protocol Versions
SSL has several versions (SSL 1.0, SSL 2.0, SSL 3.0), but all of them are now considered obsolete and insecure. SSL 3.0, the last version, is particularly vulnerable to attacks.
TLS has undergone multiple versions, with TLS 1.2 and TLS 1.3 being the latest secure versions. TLS 1.3, in particular, offers improved performance and enhanced security features.
Browser and Server Compatibility
Most modern browsers have deprecated or removed support for SSL protocols due to security concerns. TLS is the standard for secure communication, and browsers widely support it. Web servers and hosting platforms have also shifted towards TLS. Many servers no longer support SSL, and hosting providers encourage users to use TLS for enhanced security.

Compliance and Regulations
In certain industries and regions, compliance standards require the use of specific encryption protocols. TLS, being the more modern and secure option, aligns better with these compliance standards.
Performance Impact
TLS 1.3, the latest version, is designed for better performance. It reduces latency, improves connection times, and enhances overall website speed compared to older SSL versions.
Implementation in WordPress
WordPress recommends and supports the use of TLS for securing communication between the server and users. Most plugins and themes are designed to work seamlessly with TLS. Due to security concerns, major web browsers are also gradually deprecating support for SSL. Using TLS ensures compatibility with evolving web standards and future-proofing your website.

To Conclude
Given the security vulnerabilities and deprecated status of SSL, it is strongly recommended to use TLS for securing your WordPress site. TLS provides not only enhanced security but also better performance and compatibility with modern web standards. When configuring your website’s security settings, prioritize the use of TLS protocols, especially TLS 1.3, to ensure a secure and compliant online environment for your users.
