All SSL Certificates will ensure your data send from your website (forms, logins etc..) is sent encrypted (HTTPS://).  Starting in July of 2018, Google will now penalize your site in search results if it does not have an SSL Certificate. It will also mark it as not Secure. 
We offer several common SSL Certificates to meet your needs, starting at a couple bucks a month.  You can view and compare SSL Certificates here.

The price includes having Northwoods Web Designs install it to your account.  Its possible your website needs internal code changes to fully operate within an HTTPS environment, we can review it and provide a quote of the estimated work effort to assure your site will be fully HTTPS operational after the installation of a SSL Certificate.
