Need to make site secure?

It never hurts to add a layer of security to your site, but your website doesn’t get banking or credit card information. PayPal handles all that. However, you are still getting some personally identifiable information, so you should make sure to update your site regularly, keep plugins up to date, and possibly use a security plugin like Wordfence, Securi, or iThemes Security. I use all of them on most of my sites.
