xFi Blocking My Org's Website

Hi, it appears my website is being blocked by Comcast's advanced security settings. The website is www.sonomaequity.org and I need to figure out how to make sure everyone can see the site. Right now, many people are seeing it blocked as a security issue. @ComcastJosh I saw in a different forum you've been able to help with that. Can you help clearing this up? Thanks!
