An SSL certificate secures the connection between your website and server, allowing information to be transmitted safely. Customers will access your website with https instead of the insecure http – they’ll also see a security lock in the browser.
As of July 2018, Google Chrome displays a ‘Not Secure’ warning message for all websites that do not have an SSL certificate
In May 2018, GDPR replaced the Data Protection Act. Businesses can be fined for failing to secure customer data.
SSL certificates cost us a lot less because we buy in bulk. It would cost you at least £50 per year just to buy a single certificate, plus you’ll have to figure out how to install it or pay someone to do it for you.
