Understanding SSL vs TLS: What US Enterprises Need to Know

In the realm of cybersecurity, trust is the currency that fuels the digital economy. For US enterprises, ensuring secure communication and safeguarding customer data are non-negotiable priorities. But navigating the technical landscape can often be confusing, especially when it comes to understanding SSL Certificates and TLS Certificates. While these terms are frequently used interchangeably, they represent distinct stages in the evolution of encryption protocols. 

At eMudhra, we understand the importance of security in fostering trust. We enable organizations to leverage robust encryption technologies like SSL and TLS for secure and seamless digital interactions. This blog aims to clarify the differences between SSL and TLS, helping you make informed decisions for your enterprise. 

What Are SSL and TLS? 

• SSL (Secure Sockets Layer) 

Developed in the mid-1990s, SSL was the original encryption protocol used to secure internet communications. SSL established the foundation for encrypted communication by encrypting data exchanged between clients (like web browsers) and servers. This ensured that sensitive information, such as login credentials and credit card details, was protected from prying eyes. 

However, SSL had its limitations and vulnerabilities, leading to the need for stronger encryption protocols. The last version of SSL, SSL 3.0, was deprecated in 2015 due to significant security flaws. 

• TLS (Transport Layer Security) 

TLS Certificates succeeded SSL and are now the standard protocol for secure communications. TLS offers enhanced encryption, authentication, and integrity compared to its predecessor. While many still refer to secure certificates as "SSL Certificates," most enterprises today use TLS for secure communication. 

TLS operates in two primary versions: 

• TLS 1.2: Widely adopted and highly secure. 

• TLS 1.3: Introduced in 2018, it delivers faster performance and improved security by eliminating older cryptographic algorithms. 

Key Differences Between SSL and TLS 

While TLS is an upgraded version of SSL, understanding the differences is crucial for businesses aiming to implement the best security practices: 

• Encryption Strength: TLS uses stronger encryption algorithms compared to SSL, making it more resilient to modern cyber threats. 

• Handshake Process: The TLS handshake process is faster and more efficient, reducing latency during secure communication. 

• Compatibility: TLS supports Perfect Forward Secrecy (PFS), ensuring past communications remain secure even if encryption keys are compromised. 

• Support and Updates: SSL is obsolete, while TLS continues to receive updates and enhancements, with TLS 1.3 being the latest version. 

Why SSL Certificates Are Still Relevant?

Despite the shift to TLS, the term SSL Certificates is still widely used in the industry. This is because the digital certificates enabling encrypted communication were first associated with SSL. Today, these certificates support both SSL and TLS protocols, depending on the server configuration. 

For enterprises, investing in modern certificates that support TLS Certificates is essential to ensure secure transactions and maintain customer trust. 

The Importance of SSL/TLS for US Enterprises 

In 2024, cyberattacks cost US businesses over $9.44 million on average per breach (IBM Cost of a Data Breach Report 2023). Secure communication protocols like TLS are critical to protecting sensitive data and maintaining compliance with regulatory frameworks such as HIPAA, GDPR, and CCPA. 

Key Applications of SSL/TLS in Business: 

• Securing E-commerce Transactions: Protecting payment information during online transactions. 

• Email Security: Encrypting email communications to prevent data leaks. 

• Remote Work Security: Safeguarding connections to enterprise systems for remote workers. 

• IoT Device Communication: Ensuring secure data exchange in IoT ecosystems. 

Statistics Highlighting the Need for TLS Certificates 

• Over 95% of web traffic is encrypted today, a significant increase from just 50% in 2016 (Google Transparency Report). 

• Adoption of TLS 1.3 has grown by 33% year-over-year, as businesses prioritize faster, more secure encryption (SSL Labs). 

Choosing the Right Certificates for Your Enterprise 

For US businesses, transitioning from SSL to TLS Certificates is not just a best practice—it’s a necessity. Here’s how to ensure you’re making the right choice: 

• Invest in Modern Certificates: Ensure your certificates support the latest TLS versions, including TLS 1.2 and TLS 1.3. 

• Monitor Certificate Lifecycles: Avoid expired certificates that can disrupt services and erode trust. 

• Automate Certificate Management: Use solutions like emSign to streamline issuance, renewal, and monitoring.
