To remain competitive you must protect the data of your visitors & customers by confirming the security of your website.
Business owners providing services or commerce via the internet must protect sensitive information by ensuring that communication between the customer, the application, and the web server is secure.
In October 2017 Google launched a new effort to standardize security on all websites by displaying a NOT SECURE warning on websites without valid security. Website owners that have yet to install an SSL certificate run the risk of losing clients who may fear having their data stolen by doing business on an unsecured website.
Having an SSL certificate installed on the server meets this requirement.
