Adding an SSL certificate provides an extra and crucial layer of protection against malicious attacks.
Even if the website doesn’t accept transactions, you still need to protect users’ login details, addresses, and other personal information.
Websites without SSL certificates use HTTP, a text-based protocol, meaning it’s easier to intercept and read its traffic. HTTPS uses cryptographic keys to encrypt data, providing more complex security and making it difficult for potential attackers to intercept the data exchange.
Thus, the HTTPS protocol protects your website against digital threats such as man-in-the-middle (MITM) attacks. These attacks take place when someone intercepts the traffic between the website’s server or the client’s browser.
Attackers may either steal information exchanged or redirect traffic to a phishing website, where they ask for login credentials or other sensitive data.
Even if an attacker intercepts your connection, having an SSL certificate ensures that they cannot decrypt the information passed.
