Hotspot Shield vs. Project Shield Comparison Chart

Project Shield, created by Google Cloud and Jigsaw and powered by Google Cloud Armor, provides free unlimited protection against DDoS attacks, a type of digital attack used to censor information by taking websites offline. Project Shield filters out malicious traffic using Google's infrastructure and DDoS tools. If your website is targeted by a DDoS attack, our servers will block attacking traffic to keep your website up and running. Project Shield can be configured to fetch content from your website's servers once and serve a cached copy on subsequent requests. This reduces traffic to your servers and absorbs potential DDoS attacks. Project Shield caches content to strengthen DDoS defenses, improve site performance, and save bandwidth to sites. Users have the ability to invalidate caches for their site's needs. Project Shield provides controls such as JavaScript cookies and IP denylists for increased site protection.
