What is an SSL certificate?

An SSL certificate is a digital certificate that ensures a secure and encrypted connection between a website and its visitors. It protects sensitive information like passwords and credit card details from unauthorized access. It also provides visual indicators, like the padlock icon and "https://" in the URL, to reassure users of a secure connection. An SSL certificate enhances customer trust, boosts website credibility, and safeguards valuable online assets.
