• Web Application Firewall - Helps prevent automated attacks, SQL injections & XSS javascript injections!

HTTP/2 provides significantly faster page load times than HTTP because of its ability to deliver more HTTP requests at once and prioritize those requests. HTTP/2 delivers files 20%-30% faster than HTTP. Based on Google's SPDY project, HTTP/2 actually marks the first major HTTP update since 1999!

SPDY is a Google developed protocol designed to deliver website content both faster and more securely. While SPDY is available with your A2 Hosting account, Google has announced SPDY will be replaced by HTTP/2.

With ESI, you no longer have to designate an entire page as non-cacheable just because one portion cannot be cached. Instead you can easily designate portions of your page to be cached (or not cached) with ESI. This is significant especially for sites created by applications like Magento or WordPress.

WebSocket's create two-way interaction between a browser and a website possible for a realtime web experience.
