We just launched myracloud which is an IaaS for protecting sites from DDoS attacks.

This is a very affordable solution which proxies your website, and we filter out all bad traffic.

Compared to Verisign/Prolexic/Akamai this is a very affordable solution which offers even more fantastic features. E.g. InstantDisplay delays executing Javascript (inline+external) until the page has rendered.

No changes necessary, we do all the hard work.
