We do everything everything in our power to keep you site safe and secure, as with any security, you are only as strong as your weakest link.
Here are a handful of basic security precautions you should be taking with any website:
Use a strong password for your hosting account, FTP accounts, email accounts, and any other accounts associated with your website. Do not use the same password for all your different accounts. Do not email your password or store it in plain text anywhere. Keep all of your software and plugins up to date. Back up your data regularly. Enable HTTPS on your site by getting an SSL certificate.
