SSL Statistics By Cipher Usage, Certificate Market And Industry Trend (2025)

Introduction

SSL Statistics: SSL, also known as Secure Sockets Layer, is an encryption-based Internet security protocol that locks the shares of information between a website and your browser. SSL helps in building trust by creating a secure connection, which keeps personal details like passwords, credit card numbers, and messages private and secure. Without SSL, websites are more vulnerable to data theft and cyberattacks.

This article encompasses all current statistical analyses, drawing on various insights, covering the overall market trend, key features, industry usage, country-specific trends, and numerous other factors.

• When a website uses SSL/TLS, its web address starts with “https” instead of just “http”, which makes the connection more encrypted.
• Data is scrambled with strong algorithms so that only the sending and receiving computers can read it.
• Websites present digital certificates from trusted authorities to prove they are legitimate.
• Message Authentication Codes (MACs) are used to ensure the data hasn’t been changed during transit.
• Each session uses temporary keys to keep the past session data safe.
• The handshake process decides the version, encryption methods, and verifies the parties.
• SSL works with most browsers, servers, and major internet protocols.
