SSL vs. TLS. What is the Difference?

The typical internet user may give security a little nod when completing online banking or other transactions. Still, in reality, the integrity of all internet communications should also be encrypted and secure. We will briefly examine SSL vs. TLS, the difference, and why it matters.


Secure Sockets Layer (SSL) is the original security technology protocol established to keep internet communication safe with an encrypted link between a website/browser and a server. This digital certificate authenticates the website’s identity, ensuring that the website is secure. If the website you are visiting begins with HTTPS://and you visually see a padlock, it has an SSL certificate. Multiple encryptions and validation certificates fall under the umbrella of SSL, which we won’t discuss in this blog.


Transport Layer Security (TLS) is the updated version of the standard SSL. The terms SSL and TLS are often used interchangeably when discussing security certificates. The newest version, TLS 1.3, “was “introduced to reduce unsafe technologies like outdated algorithms, enable backward compatibility with older protocol versions, speed up connections, improve security, and use newer techniques like allowing fewer, more trusted cipher options (


TLS and SSL are relatively the same; however, there are minor differences in the mechanisms of how they work. This chart is adapted from and breaks down these differences.

Websites need an SSL or TLS Certificate to protect and prevent hackers from creating fake websites. This credibility and trust are passed on to the users, ensuring their data and information are secure.
